Reg. 10.28 Current through Register 1517, March 15, 2024 Section 10.28 - Coastal Dunes(1)Preamble. All coastal dunes are likely to be significant to storm damage prevention and flood control, and all coastal dunes on barrier beaches and the coastal dune closest to the coastal beach, also known as the Primary Frontal Dune as defined in 310 CMR 10.04, in any area are per se significant to storm damage prevention and flood control. The Coastal. High Hazard Area or Velocity Zone extends at a minimum to the inland limit of the Primary Frontal Dune along the open coast. Coastal dunes are also often significant to the protection of wildlife n habitat. to Coastal dunes aid in storm damage prevention and flood control by supplying upp y g sand coastal beaches. Coastal dunes protect inland coastal areas from storm damage and flooding by storm waves and storm elevated sea levels because such dunes are higher than the coastal beaches which they border. In order to protect this function, coastal dune volume must be maintained while allowing the coastal dune shape to conform to natural wind and water flow patterns. Vegetation cover contributes to the growth and stability of coastal dunes by providing conditions favorable to sand deposition. On.tetreating shorelines, the ability of the coastal dunes bordering the coastal beach to move landward at the rate of shoreline retreat allows these dunes to maintain their form and volume, which in turn promotes their function of protecting against storm damage or flooding. A number of birds, most commonly terns and gulls, nest at the base or sides of dunes. In some dune systems other birds also nest in the interdunal area, the species being determined by the plant community structure, topography, and hydrologic regime of the area. In a few dune systems, wet meadows or vernal pool habitats occur, which serve as important feeding areas for a wide variety of bird species. When a proposed project involves the dredging, filling, removal or alteration of a coastal dune, the issuing authority shall presume that the area is significant to the interests of storm damage prevention, flood control and the protection of wildlife habitat. This presumption may be overcome only upon a clear showing that a coastal dune does not play a rote in storm damage prevention, flood control or the protection of wildlife habitat, and if the issuing authority makes a written determination to that effect. When a coastal dune is significant to storm damage prevention, flood control or the protection of wildlife habitat, the following characteristics are critical to the protection of those interest(s): (a) the ability of the dune to erode in response to coastal beach conditions;(b) dune volume;(c) dune form, which must be allowed to be changed by wind and natural water flow;(d) vegetative cover;(e) the ability of the dune to move landward or laterally; or(f) the ability of the dune to continue serving as bird nesting habitat.(2)pefinition. Coastal Dune means any natural hill, mound or ridge of sediment landward of a coastal beach deposited by wind action or storm overwash. Coastal dune also means sediment deposited by artificial means and serving the purpose of storm damage prevention or flood control. WHEN A COASTAL DUNE IS DETERMINED TO BE SIGNIFICANT TO STORM DAMAGE PREVENTION, FLOOD CONTROL OR THE PROTECTION OF WILDLIFE HABITAT, 310 10.28(3) THROUGH (6) SHALL APPLY: (3) Any alteration of, or structure on, a coastal dune or within 100 feet of a coastal dune shall not have an adverse effect on the coastal dune by:(a) affecting the ability of waves to remove sand from the dune;(b) disturbing the vegetative cover so as to destabilize the dune;(c) causing any modification of the dune form that would increase the potential for storm or flood damage;(d) interfering with the landward or lateral movement of the dune;(e) causing removal of sand from the dune artificially; or(f) interfering with mapped or otherwise identified bird nesting habitat.(4) Notwithstanding the provisions of 310 CMR 10.28(3), when a building already exists upon a coastal dune, a project accessory to the existing building may be permitted, provided that such work, using the best commercially available measures, minimizes the adverse effect on the coastal dune caused by the impacts listed in 310 CMR 10.28(3)(b) through (e). Such an accessory project may include, but is not limited to, a small shed or a small parking area for residences. It shall not include coastal engineering structures.(5) : The following projects may be permitted, provided that they adhere to the provisions of 310 CMR 10.28(3):(a) pedestrian walkways, designed to minimize the disturbance to the vegetative cover and traditional bird nesting habitat;(b) fencing and other devices designed to increase dune development; and(c) plantings compatible with the natural vegetative cover.(6) Notwithstanding the provisions of 310 CMR 10.28(3) through (5), no project may be permitted which will have any adverse effect on specified habitat sites of Rare Species, as identified by procedures established under 310 CMR 10.37. 310 CMR 10.28 Amended by Mass Register Issue 1272, eff. 10/24/2014.

The proposed project involves the installation of pervious pavers, a small addition to a red brick ground -level patio and an After the Fact permit for the previous installation of a redbrick patio and an above ground hot tub. All of this work is inside the 100 foot buffer zone to Upper Mill Pond. The property was purchased in 2003. Roughly a year later we installed an above ground hot tub and a red brick patio off a walk out basement. Both installations were done within the 100 foot buffer to Upper Mill Pond. Neither installation secured the approval of the Conservation Commission due to our ignorance of the DEP requirement. In March 2017 we filed an RDA for the installation of a retaining wall necessitated by the construction of a one car garage on the southwest side of our property. That wall is also inside the 100 foot buffer zone. The ConsCom reviewed the application and unanimously agreed that the proposed work "is not subject to the review and approval by the Town of Brewster". The retaining wall was installed shortly thereafter. This current project seeks to install pervious pavers across the existing footprint defined by the retaining wall and add additional red bricks to the existing walk out patio. The proposed work area is approximately 500 square feet. Thank you in advance for your consideration.

Lean why this is important Dear Ms. Wright, I received your phone inquiry regarding the project at 8 Marshview Lane in Brewster. After speaking with the staff reviewer who was assigned to the project, I learned that because the project was only slated for local archaeological review (i.e. Brewster Conservation Commission Order of Conditions) the MHC did not choose to comment on the project. Because the MHC did not comment within 30 days the project may proceed as planned (see out FAQ page here: hms://www.sec.state.ma.us; mhc;'mhcrevcom!revcomidx.htm ) Please let me know if I can provide any further information.

The Division also received the MESA Review Checklist and supporting documentation for review pursuant to the MA Endangered Species Act Regulations (321 CMR 10.18). A portion of the proposed Project, as currently proposed, will occur within the mapped habitat of Salt Reedgrass (Spartina cynosuroides), a state -listed Threatened species. This species and its habitats are protected in accordance with the MESA. WETLANDS PROTECTION ACT (WPA) Based on a review of the information that was provided and the information that is currently contained in our database, the Division has determined that this project, as currently proposed, will not adversely affect the actual Resource Area Habitat of state -protected rare wildlife species. Therefore, it is our opinion that this project meets the state -listed species performance standard for the issuance of an Order of Conditions. Please note that this determination addresses only the matter of rare wildlife habitat and does not pertain to other wildlife habitat issues that may be pertinent to the proposed project.

O'Reilly & Associates, Inc. 1573 Main Street Brewster, MA 02361 Re: 8 Marshview Drive, Brewster, MA Mr. O'Reilly, This letter is an environmental assessment report concerning the above mentioned undeveloped property, wooded property, located at 8 Marshview Drive, at the intersection of Marshview Drive and Upland Circle in Brewster, MA. Independent Environmental Consultants, Inc. (IEC) conducted a site inspection and evaluation on 2-27-24 to review the existing wetland delineation flagging of the wetland resource areas located within this subject coastal property. The wetland resource areas were delineated by Matthew Farrell of J.M. O'Reilly & Associates, Inc. The subject wooded property is located at the intersection of Marshview Drive and Upland Circle in Brewster. Existing topography drops in elevation from Marshview Drive to existing wetlands located downgradient within the property. There is a salt marsh located at the lowest elevation within this property. The salt marsh contains a large stand of Phragmites Communis, an invasive plant species. The landward limit of salt marsh has been delineated in the field by Matthew Farrell. This delineation of the boundary of the salt marsh is correct. There is a bordering vegetated wetland (BVW), wooded swamp, located at the bottom of slope. The edge of wetlands for the BVW wetland is located slightly upgradient of the previous mentioned boundary of the salt marsh. At the delineated edge of the BVW wetland, there is a minor inland bank feature (raised topography) located directly adjacent to the delineated boundary of bvw wetland. The wooded swamp continues downgradient connecting to the previously mentioned salt marsh. The BVW wetland contains greater than 50% wetland vegetative species, hydric soils, saturated soils, and high groundwater conditions. The inland bank feature at the delineated edge of wetlands physically contains the subject BVW wetland (wooded swamp) located at the bottom of slope. The delineation of the edge of wetlands (BVW) by Matthew Farrell is a very reasonable and correct wetland delineation. The BVW wetland continues off property. The BVW wetland has a 50' buffer zone and a 100' buffer zone associated with the edge of wetlands. The 100' buffer zone extends upgradient towards Marshview Drive, and Upland Circle. The low-lying BVW wetland is hydrologically connected to the downgradient salt marsh (coastal wetland), which is subject to daily coastal flows of tidal marine waters. A FEMA 100 year flood zone (land subject to coastal storm flowage) is associated within this coastal wetland system. Sections of this property may be classified as Estimated and/or Priority Habitat of Endangered & Rare Species by NHESP. The wetland delineations of the salt marsh and the BVW wetland by Mathew Farrell are accurate wetland delineations within this subject undeveloped property at 8 Marshview Drive. Again, there is a minor inland bank feature located at the delineated edge of BVW wetlands within the field, at the delineated wetland edge located closest to Marshview Drive/Upland Circle. According to site plans and the field staking located within the field, there are no proposed site alterations located within the salt marsh, the BVW wetland, the inland bank, or the 50' buffer zone measured from the edge of BVW wetland and the inland bank feature. The wetland resource areas and wetland buffer zones are under the jurisdiction of the Brewster Conservation Commission, and DEP SERO. Paul J. Shea, PWS President qVA J.M. & O'REILLY ASSOCIATES, INC.

O'REILLY & ASSOCIATES INC., is requesting the Brewster Conservation Commission review and approve an Order of Conditions for the construction of a single family dwelling at the above referenced vacant property. Along with the offices of J.M. O'REILLY & ASSOCAITES, the project team includes the project architect Ms. Leslie Schneeberger of Schneeberger Collective, and the Landscape Architect Thomas Mulcahy of Mulcahy Design Group. The enclosed submission package includes copies of the Site & Sewage Disposal System Plan (Site Plan), a landscape plan (2 sheets) and the schematic house plans Plan (4 sheets) all of which outline the proposed improvements to the parcel. The Applicant purchased the property from her family members, in October 2021, to build her home in Brewster. The Pagos family originally purchased the property in 1996 so her parents could build a summer home. The parents, due to personal issues, did not build on the parcel. The parcel represents one of the last vacant parcels in the Seaview Subdivision. Wetland Resources: This property is somewhat unique in the configuration of the parcel and the varied wetland resources associated with it. The parcel contains about 99,575 sf of land area. The northern portion of the parcel has a small area above the 14 -foot contour, which represents the 100 -year flood boundary. The larger portion of upland is the southern portion of the parcel, adjacent to the roadway. The southern portion of the parcel is proposed to be improved with the single family dwelling. The two upland areas are separated by vegetated wetlands. The upland portion of the southern area is approximately 42,000 sf of land area. The parcel is bordered to the north by the large salt marsh system which is associated with the Namskaket Creek. A portion of the salt marsh extends south onto the parcel on the west. This landward extent of the salt marsh has been flagged using eight (8) points and has been labeled in the field as SM1 to SM8. No work is proposed within the BVW. 1573 MAIN STREET, P.O. BOX 1773, BREVVSTER, MA 02631 • PHONE: (508) 896-6601 • FAX: (5o8) 896-6602 WWW.JMOREILLYASSOC.COM 2 Adjacent to the salt marsh, to the east, is a bordering vegetated wetland (BVW). The BVW is located at the bottom of a small bank and runs east from the salt marsh and over to the abutting properties to the north-east. The landward extent of the BVW has also been flagged using seven (7) points and has been labeled in the field as BV1 to BV7. No work is proposed within the BVW. Also adjacent to the BVW and salt marsh is an elevated landform which, due to the 100 -year flood elevation, is defined as a Coastal Bank. The 100 -year flood boundary is Zone AE with a base flood elevation of 14. The 14 -foot contour intersects the existing slope and as per the MA DEP Wetlands Program Policy - 92-1, the coastal bank has been defined as either the 14 -contour line OR at the break in slope of less than 4 to 1 (4:1). The Bank has been defined using Figures 2 & 3 of Policy 92-1. No work is proposed on the Coastal Bank The parcel also contains an area of Estimated Habitats of Rare Wildlife. The boundary of the Rare Species is shown on the Site Plan. The location of the boundary falls along the limit of work line on the west side of the parcel and then runs in a northeast direction down the slope and away from the proposed dwelling on the east. A copy of the application has been sent to the Natural Heritage Program for review and comment. No work is proposed within the mapped area for Rare Species. The portion of the parcel from the edge of the BVW to the north is within the Inner Cape Cod Bay ACEC. The ACEC boundary is the 10 -foot contour which corresponds to the bottom of the slope at the BVW. Similar to the BVW, no work is proposed within the ACEC Boundary. The 50 and 100 -foot Buffer Zones have been established from the location of the Coast Bank. The project involves work within the 50 to 100 -foot Buffer Zone. No work is proposed within the 50 -foot Buffer. Please refer to the Site Plan for additional notes and details of the resources. Project Narrative: The Applicant proposes to construct a single family dwelling, decks, driveways and landscape on the locus parcel. The dwelling footprint is approximately 2,490 sf, which includes a cantilevered area along the north (rear) side of the dwelling. The rear portion of the dwelling includes a partial walkout basement adjacent to the elevated deck. Adjacent to the rear wall of the dwelling the Applicant has proposed a 3 - foot wide stone (gravel) walkway. The walkway will serve as an access point to the walk out area and rinse station. The dwelling has been designed according to the area available for the proposed structure. The location of the 50 -foot Buffer from the Bank and the 40 -foot front building setback from the roadway dictates the shape of the house to run more east to west (width) rather than north to south (depth). The proposed width of the dwelling is about 106 feet long and varies in depth from 24 feet to 26 feet. The Applicant and the team informally met with the Commission in January to seek some input on the dwelling and proposed location. The Applicant listened to the Commission and has worked with the team to reconfigure the footprint layout, shift the footprint to the west and slightly reduced the dwelling's footprint. Although the house appears to be sprawling, the 2,500 sf home footprint is in keeping with the existing home sizes in the neighborhood. The 2,500 sf home footprint represents a building coverage of about 6% +1- of the southern portion of the locus parcel. PAGOS-HALLER NOTICE OF INTENT 8 MARSHVIEW LANE FEBRUARY 22, 2024 BREWSTER, MA JMO-9042 3 As stated above the dwelling has been designed to account for the available room for the structure. The dwelling's basement elevation has been designed to account for the existing grades along the rear of the dwelling. The distance between the proposed limit of work line and the dwelling is close at 5 feet on the west and just over 7.5 feet on the east, adjacent to the walkout. Obviously, we contend the dwelling can be built and maintained with the proposed limit of work. To support our opinion, we have added to the Site Plan a section (Section A — 'A') at the closest point to the Limit of Work Line, the rear western corner of the proposed dwelling. This point is also the location of the deepest excavation to install the footing for the foundation. The soil testing completed for the sewage system design was similar to other properties this office has worked on within the Seaview Subdivision. The area contains a significant layer of silt loam soil over a medium or fine sandy material. The soil testing completed on the western portion of the parcel found a silt loam material between 32 and 34 -inches below existing grade. The section shows the footing and wall can be constructed without impacting the proposed limit of work line. The silt loam material is a very firm soil which will hold a near vertical sidewall (Soil Type A — Slope %2 to 1) and allows for the 5 foot excavation to the top of the footing (bottom of basement slab). The sandy topsoil and subsoil will be stabilized at a 1 to 1 slope for the construction. Once backfilled the grade at the building corner will be slightly lower than the existing grade at the limit of work boundary. The slope of 4 to 1 will be landscaped and stabilized per the landscape plans. In addition to the dwelling, the project proposes a sewage system for the potential 4 bedroom dwelling, stormwater controls, driveways with walkways and a native landscape proposal. Please refer to the Site Plan for additional details and notes. The limit of work line for the project is proposed to be a combination of both a 9 -inch straw wattle and an erosion (silt) fence. The bottom of the fence will be dug into the ground and then fortified with the straw wattle along the base. Upon the completion of the landscape, a series of 1.5 -foot dia. boulders shall be placed along the limit of work line to delineate the limit of activities on the parcel. Please refer to the Site Plan for the limit of Work details and boulder locations. The project does trigger a Major Stormwater Permit from the Town of Brewster. Under a separate cover, the Applicant has provided the Commission with the applicable reports and calculations to reflect that the project is designed in accordance with the requirements of the Town of Brewster Stormwater Regulations. The stormwater facilities include two water quality swales and two subsurface leaching facilities. The swales are proposed to handle the stormwater from the two driveways proposed for the dwelling. Although the majority of the two driveways are beyond the 100 -foot Buffer, the water quality swales do represent a benefit to the water quality of the parcel's runoff. The swales will address hydrocarbons from the driveway areas as well as the phosphorus and nitrogen runoff from the landscape areas. The drainage facilities have been designed to limit the post construction runoff to less than the pre -construction peak discharge. Please refer to the Stormwater Permit Application for additional information and details. Work Protocol: PAGOS-HALLER 8 MARSHVIEW LANE BREWSTER, MA NOTICE OF INTENT FEBRUARY 22, 2024 JMO-9042 4 1. Prior to starting work, the Applicant shall obtain all necessary state and local permits associated with the construction of a single family dwelling. 2. The limit of work line shall be re -staked prior to the installation of the wattles and fence along work limit line. Prior to installation, the contractor shall coordinate the installation of the limit of work line with the Brewster Conservation Agent to address any vegetation in the way of the work line. 3. Trees and vegetation shall be cut and removed from the project site. 4. The stumps shall be grubbed, and the topsoil removed. The stumps are to be removed from the project area. The topsoil can be removed or stockpiled for use later. The stockpile material shall be beyond the 100 foot Buffer zone and protected with a row of straw wattles, on the down hill side of the pile. 5. The excavation for the foundation shall be completed. The frost footings along the rear of the dwelling shall be constructed first then the remaining footings installed. Once the footings are ready, the concrete foundation walls can be constructed. 6. The backfilling of the foundation shall be completed. The rear portion of the foundation shall be backfilled from the inside of the foundation. The foundation walls along the rear of the building are not full walls and can be easily backfilled without having to place a machine at the rear. 7. Once the foundation is complete the wood frame portion of the dwelling shall be started. 8. The swales shall be constructed once the home is tight to the weather. The swales shall be constructed to time with the seasonal planting periods (Spring or Fall). The planting season will allow the swales to be established so when the final landscape is completed and stabilized, the swales can be utilized. a. The contractor shall review Stormwater Operation and Maintenance Report, as developed under the Brewster Stormwater Permit. b. The swales shall be protected during construction with a straw wattle along the top crest of the swale and along the bottom of the swale. Two rows of straw wattles for each Swale. 9. The subsurface leaching facilities and sewage system can now be installed. Connect all leaching facilities with the piping from the swales and the roof leaders. 10. Complete the final landscape and hardscape improvements. 11. Monitor the planted vegetation and replace as necessary if not successful. Refer to the Orders of Conditions for monitoring and reporting requirements for the project. Pertormance Standards: Salt Marsh (310 CMR 10.32): The proposed project activities are within the Buffer Zones the salt marsh. The boundary of the salt marsh is about 84 feet to the Limit of Work Line. The proposed walkway and dwelling are proposed to be about 85 and 88.5 feet, respectively. As such: Salt Marsh 310 CMR 15.32 WHEN A SALT MARSH IS DETERMINED TO BE SIGNIFICANT TO THE PROTECTION OF MARINE FISHERIES, THE PREVENTION OF POLLUTION, STORM DAMAGE PREVENTION OR GROUND WATER SUPPLY, 310 CMR 10.32(3) THROUGH (6) SHALL APPLY: PAGOS-HALLER NOTICE OF INTENT 8 MARSHVIEW LANE FEBRUARY 22, 2024 BREWSTER, MA JMO-9042 5 (3) A proposed project in a salt marsh, on lands within 100 feet of a salt marsh, or in a body of water adjacent to a salt marsh shall not destroy any portion of the salt marsh and shall not have an adverse effect on the productivity of the salt marsh. Alterations in growth, distribution and composition of salt marsh vegetation shall be considered in evaluating adverse effects on productivity. • The proposed activities will take place about 84 feet from the edge of the salt marsh. The native vegetation between the proposed limit of work and the Salt Marsh will remain and will continue to provide significant buffer to the resource. • The stormwater controls, specifically the western swale within the lawn area, were designed to catch the surface runoff from the front lawn area. The stormwater will be contained within the shallow swale and will prevent potential direct discharges towards the resource areas to the north, including the Salt Marsh. (4) Notwithstanding the provisions of 310 CMR 10.32(3), a small project within a salt marsh, such as an elevated walkway or other structure which has no adverse effects other than blocking sunlight from the underlying vegetation for a portion of each day, may be permitted if such a project complies with all other applicable requirements of 310 CMR 10.21 through 10.37. • Not applicable, the Applicant is not proposing any walkway over or through the Salt Marsh. (5) Notwithstanding the provisions of 310 CMR 10.32(3), a project which will restore or rehabilitate a salt marsh, or create a salt marsh, may be permitted in accordance with 310 CMR 10.11 through 10.14, 10.24(8), and/or 10.53(4). • Not applicable, the project does not include any alteration within the Salt Marsh. (6) Notwithstanding the provisions of 310 CMR 10.32(3) through (5), no project may be permitted which will have any adverse effect on specified habitat sites of Rare Species, as identified by procedures established under 310 CMR 10.37. • The Salt Marsh and a portion of the upland area is within a mapped area of Rare Wildlife. As such the Applicant has submitted the Notice of Intent to the Natural Heritage Program for review and guidance. Coastal Bank (310 CMR 10.30): The proposed project activities are within the Buffer Zones of the Coastal Bank. As noted above, the Bank has been determine based on the MA DEP Wetlands Program Policy - 92-1. THE Bank is an elevated Iandform which is significant to flood damage prevention and is NOT a sediment source to a Coastal Beach. As such: 310 CMR 10.30: WHEN A COASTAL BANK IS DETERMINED TO BE SIGNIFICANT TO STORM DAMAGE PREVENTION OR FLOOD CONTROL BECAUSE IT IS A VERTICAL BUFFER TO STORM WATERS, 310 CMR 10.30(6) THROUGH (8) SHALL APPLY: (6) Any project on such a coastal bank or within 100 feet landward of the top of such coastal bank shall have no adverse effects on the stability of the coastal bank. PAGOS-HALTER 8 MARSHVIEW LANE BREWSTER, MA NOTICE OF INTENT FEBRUARY 22, 2024 JMO-9042 6 • The closest excavation area to the Bank is on the western side of the rear corner of the proposed dwelling. The detail section on the Site Plan shows the limit of excavation will be to the Limit of Work line, 51 feet away from the Bank. The excavation needed for the foundation and the associated grading along the rear of the dwelling will NOT have an adverse impact to the stability of the Bank. (7) Bulkheads, revetments, seawalls, groins or other coastal engineering structures may be permitted on such a coastal bank except when such bank is significant to storm damage prevention or flood control because it supplies sediment to coastal beaches, coastal dunes, and barrier beaches. • Not Applicable, the project does not propose a bulkhead or revetment along the Bank. (8) Notwithstanding the provisions of 310 CMR 10.30(3) through (7), no project may be permitted which will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species, as identified by procedures established under 310 CMR 10.37. • The Coastal Bank and a portion of the upland area is within a mapped area of Rare Wildlife. As such the Applicant has submitted the Notice of Intent to the Natural Heritage Program for review and guidance. Estimated Habitat of Rare Wildlife (for Coastal Wetlands) 310 CMR 10.37: Estimated Habitats of Rare Wildlife (for Coastal Wetlands) The boundary of the Rare Species is shown on the Site Plan. No work is proposed within the mapped area. A copy of the application has been sent to the Natural Heritage Program for review and comment. Area of Critical Environmental Concern (ACEC) The portion of the parcel from the edge of the BVW to the north is within the Inner Cape Cod Bay ACEC. The ACEC boundary is the 10 -foot contour which corresponds to the bottom of the slope at the BVW. As noted above, the project does not propose any alteration of the land area within the ACEC boundary. In conclusion, J.M. O'REILLY & ASSOCAITES, INC. believes the project can be approved with conditions and not result in impacting the adjacent resources associated with the property.

O'Reilly & Associates, Inc. 1573 Main Street Brewster, MA 02361 Re: 8 Marshview Drive, Brewster, MA Mr. O'Reilly, This letter is an environmental assessment report concerning the above mentioned undeveloped property, wooded property, located at 8 Marshview Drive, at the intersection of Marshview Drive and Upland Circle in Brewster, MA. Independent Environmental Consultants, Inc. (IEC) conducted a site inspection and evaluation on 11-21-23 to review the existing delineation flagging of wetland resource areas located within this property. The wetland resource areas were delineated by Matthew Farrell of J.M. O'Reilly & Associates, Inc. The subject wooded property is located at the intersection of Marshview Drive and Upland Circle in Brewster. Existing topography drops in elevation from Marshview Drive to existing wetlands located within the property. There is a Bordering Vegetated Wetland (BVW), wooded swamp, located at the bottom of slope. At the delineated edge of wetlands, there is a minor inland bank feature located directly adjacent to the delineated boundary of wetlands (Flags BV1 - BV7). The wooded swamp continues downgradient connecting to a low-lying wetland, with an emergent plant community, containing a large percentage of Phragmities Communis, an invasive plant species. The BVW wetland contains greater than 50% wetland vegetative species, hydric soils and high groundwater conditions. The inland bank feature at the delineated edge of wetlands contains the subject BVW wetland located at the bottom of slope. The wetlands continue off property. The BVW wetland has a 50' buffer zone and a 100' buffer zone associated with the edge of wetlands. The 100' buffer zone extends towards Marshview Drive, and Upland Circle. The low-lying wetlands are connected to coastal wetlands which are subject to coastal flows during coastal storm events. A FEMA 100 year flood zone may be associated within this wetland system. Sections of this property may be classified as Estimated and/or Priority Habitat of Endangered & Rare Species by NHESP. The wetland delineation of the BVW wetland by Mathew Farrell is an accurate wetland delineation within this subject property at 8 Marshview Drive. Again, there is a minor inland bank feature located at the delineated edge of wetlands in the field, at the wetland edge closest to Marshview Drive/Upland Circle (Flags BV1— BV7). Paul J.

MHC #RC.50268 Dear Mr. Miller: Staff of the Massachusetts Historical Commission (MHC) have reviewed the Project Notification Form (PNF) prepared and submitted by Tighe & Bond, Inc for the project referenced above, and the MHC's files. The PNF indicates that the project requires permitting from the US Army Corps of Engineers, the Massachusetts Department of Environmental Protection, and the Brewster Conservation Commission. The PNF and project plans indicate that the project includes the rehabilitation to the Stony Brook Grist Mill Headrace Pond Retaining Wall. Tasks include repairing and replacing stone masonry walls in the headrace pond and improvements to an associated fishway. The Stony Brook Grist Mill Headrace Pond Retaining Wall project area of potential effect is located within the Stony Brook -Factory Village Historic District (BRE.J), which is included in the National Register of Historic Places. The project area of potential effect also includes the Stony Brook Gristmill (BRE.66), listed in the National Register of Historic Places. After review of the information submitted, the MHC believes that the project will have "no adverse effect" (36 CFR 800.5(b); 950 CMR 71.07(2)(b)(2)) on the Stony Brook -Factory Village Historic District (BRE.J) or the Stony Brook Gristmill (BRE.66) and is unlikely to affect any other significant historic and archaeological resources. These comments are offered to assist in compliance with Section 106 of the National Historic Preservation Act of 1966 as amended (36 CFR 800), M.G.L. c. 9, ss. 26-27C (950 CMR 70-71), and MEPA (301 CMR 11). Please contact Caitriona Parker of my staff, if you have any questions or require more information.

Chapter 131, §40) and its implementing regulations and Chapter 172 of the Town of Brewster's Wetlands Protection Bylaw ("Town Bylaw"), as amended December 3, 2018, and its implementing regulations. The Stony Brook Fishway at Stony Brook Grist Mill and Museum is located at 830 Stony Brook Road and 0 Stony Brook Road in Brewster, Massachusetts. The existing grist mill and surrounding property are owned by the Town of Brewster and overseen by the Mill Sites Committee. The mill itself dates to the 1600s and has great historical significance. Additionally, Stony Brook and the mill ponds are thriving fish migration routes spawning habitat. The Lower Mill Pond Dam is located to the south of the existing grist mill and is approximately 100 -feet long. Flow is discharged from Lower Mill Pond either through the primary spillway located on the east side of the dam and down the existing fish passage channel, or through a slide gate on the west side of the dam and down the headrace pond to the grist mill. The Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project is being conducted to stabilize the stone masonry wall that retain a narrow berm separating the headrace pond from the fish channel, repair a stone masonry wall along the fish pool located upstream of the Stony Brook culvert and to install a geosynthetic clay liner (GCL) in the headrace pond to provide wall stability and longevity. Additionally, the project will also implement several improvements to the existing fishway on the north side of Stony Brook Road to enhance fish passage. These improvements entail replacing existing weirs in the fishway, the construction of additional weirs, and grouting a small section of loose stones that tend to trap fish during their migration to the Lower Mill Pond. Ongoing vegetative management within the channel, headwalls, paths, and vegetative fringe of the fish run requires periodic maintenance by Town staff, volunteers, and contractors. To ensure a viable fish passage, this work is necessary for personnel access and fish passage. This work is in keeping with prior Conservation permit approval, Determination of Applicability issued on February 10, 2021, and approved MassDEP Policy 22-1 Memorandum Fish Run Maintenance ratified by the Brewster Conservation Commission during the March 14, 2023, Commission Public Meeting with additional Special Conditions. See Appendices I, 3 & K. Given the nature of the proposed activities, the project qualifies for consideration as a Limited Project per 310 CMR 10.53(3)(i) and as an Ecological Restoration Limited Project per 310 CMR 10.53(4)(e)(5). Qualifying activities for this status include the restoration Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 1-1 Section 1 Introduction Tighe&Bond of fish passage structures and improvements to the headrace pond to minimize the impacts of hydrostatic pressure from the headrace on the structural integrity of the surrounding fishway. 1-2 SECTION 2 Tighe&Bond Section 2 Existing Environment This section provides a site description and wetland characterization for the Project Site and surrounding area. Land use in the general vicinity of the Project Site was determined through direct observations made during a site visit on October 5, 2023, and a review of data available through the Massachusetts Geographic Information System ("MassGIS"). 2.1 Project Site The Project Site is located at 830 Stony Brook Road and 0 Stony Brook Road and is identified as Map 35, Lots 47 and 15 in the Town of Brewster's Assessors Maps. The Town -owned parcels are part of a historic grist mill and are bound by Lower Mill Pond to the south, residential properties to the east, and undeveloped land to the north and west. The historic, yet operable grist mill functions as a museum and the complex (i.e. the mill building, Stony Brook, Lower Mill Pond and other, upland areas) is used for recreational activities. The iconic and historic Stony Brook fish run is designated as one of the most popular herring runs in the Commonwealth of Massachusetts'. Site access is available via Stony Brook Road, a public road. Walking trails and boardwalks adjacent to and downstream of the dam provide public access to the area. The Lower Mill Pond is the only source of water supply for the historic grist mill. Land use within the vicinity of the dam consists of mainly undeveloped lands with residential properties abutting the pond perimeter. The project location is shown on the USGS Site Location Map (Figure 1) provided in Appendix A. The site and surrounding area are also shown on the Massachusetts Department of Environmental Protection ("MassDEP") Priority Resources Map (Figure 2) and an Orthophotograph Site Plan (Figure 3) in Appendix A. Proposed construction is shown on the drawing set included in Appendix B. Photographs of the Project Site and surrounding area are provided in Appendix C. 2.2 Methodology of Resource Area Investigations Tighe & Bond conducted wetland resource area investigations within the limits of the proposed project and the area immediately surrounding the Stony Brook Grist Mill on October 5, 2023. Wetland resource areas were named based on the wetland system number alphabetical letter in the order in which they were observed (i.e., "1A-1" refers to the first resource area delineated within wetland system 1). Wetland resource areas were delineated in accordance with local, state, and federal guidelines, including the Town of Brewster Wetlands Regulations 3.02(2)(c), the Massachusetts Wetlands Protection Act (MAWPA M.G.L. c. 131 sec. 40) and associated Wetlands Protection regulations (310 CMR 10), and the United States Army Corps of 1 Massachusetts Division of Fisheries and Wildlife.

This bank coincides with the wall of the Lower Mill Pond Dam and the pond's Mean Annual High Water ("MAHW") line for most of its length within the investigation area. This bank is composed of the Lower Mill Pond Dam, a cast -in -place concrete dam faced with decorative stone. The dam maintains the pond at a constant water level, resulting in coincident mean annual low flow level and mean annual flood level. No emergent vegetation is present along the impounded portion of the bank under normal conditions. South of the dam, the bank consists of shallow vegetation on the lower fringes of the bank while the bank itself contains a mixture of buttonbush (Cephalanthus occidentalis, Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 2-2 Section 2 Tighe&Bond OBL), sweet pepperbush (Clethra alnifolia, FAC), silky dogwood (Corpus amomum, FACW), royal fern (Osmunda regalis, OBL), black locust (Robinia pseudoacacia, FACU), red maple (Acer rubrum, FAC), and Norway maple (Acer platanoides, UPL). 2.3.1.2 Flag Series 2A (Headrace Pond) The inland Bank of the headrace pond is delineated by Flag Series 2A. The pond is an impounded waterbody fed by one of the outlets of the Lower Mill Pond Dam and exhibits a consistent water level controlled by stop logs at the downstream end of the headrace pond. Consequently, the bank of the headrace pond coincides with the pond's MAHW line. Water levels within the pond are controlled via either the inlet from Lower Mill Pond, or two outlets: the grist mill's wooden raceway or the structure's wooden spillway. The banks of the headrace pond consist of rock walls for the majority of the pond's perimeter which vary in height from six (6) inches to four (4) feet and are nearly vertical for their entire length. Vegetation on the unwalled portions of the bank consisted primarily of jewelweed (Impatiens capensis, FACW), sensitive fern (Onoclea sensibilis, FACW), and cattail (Typha latifolia, OBL). 2.3.1.3 Flag Series 3A (Stony Brook) Stony Brook is a perennial freshwater stream that begins at the outlet of Lower Mill Pond, flows northward to a culvert beneath Stony Brook Road, and continues north out of the investigation area. Stony Brook is primarily characterized as a channelized fish ladder that serves as a herring run. The banks of the stream mainly consist of unvegetated, vertical stone walls three feet (3) to six (6) feet in height. 2.3.1.4 Flag Series 3B (Bypass Channel) A former millrace, the existing Bypass Channel, dates from the 17th or 18th century and is a perennial freshwater stream formed by a bifurcation of Stony Brook downstream of the culvert. The Bypass channel runs for approximately 150 feet before rejoining Stony Brook. Stop logs control the volume of water entering the Bypass Channel. The downstream portion of the Bypass channel is characterized by a steep drop-off, the location of a former mill's waterwheel, after which the channel rejoins Stony Brook. Vertical stone walls demarcate the stream banks which vary in height from six (6) feet to three (3) feet in height upstream and six (6) to eight (8) feet in height downstream of the drop-off. 2.3.2 Land Under Waterbodies and Waterways (LUW) As defined at 310 CMR 10.56(2), "LUW is the land beneath any creek, river, stream, pond or lake." LUW within the Project Site is present beneath the Lower Mill Pond (Flag Series 1A), the Headrace Pond (Flag Series 2A), Stony Brook (Flag Series 3A), and the Bypass Channel (Flag Series 3B). 2.3.2.1 Flag Series 1A (Lower Mill Pond, LU1BH) Flag Series 1A demarcates the limits of Lower Mill Pond's LUW. This LUW coincides with the foot of the Lower Mill Pond Dam and the pond's Mean Annual Low Water (MALW) line for most of its length. This limits of the LUW is defined by the Lower Mill Pond Dam and the banks of the pond. The dam maintains the pond at a constant water level, resulting in coincident mean annual low flow level and mean annual flood level. The pond substrate consists of unconsolidated sediment and some unidentified aquatic vegetation is also present. No emergent vegetation is present along the impounded portion of the Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 2-3 Section 2 Tighe&Bond bank under normal conditions. The pond is fringed by swamp loosestrife (Decodon verticillatus, OBL) to the south of the dam. 2.3.2.2 Flag Series 2A (Headrace Pond, LU1BH) The LUW of the Headrace Pond is delineated by Flag Series 2A. The pond is an impounded waterbody fed by Lower Mill Pond that exhibits a consistent water level. Consequently, the LUW of the headrace pond coincides with the pond's MAHW line. Water levels within the pond are controlled via either the inlet from Lower Mill Pond or two outlets: the grist mill's wooden raceway or the structure's wooden spillway. The LUW limits of the headrace pond consist of retaining walls for the majority of the pond's perimeter. The pond's substrate consisted of unconsolidated sediment with some unidentified submergent aquatic vegetation present. About 20% of the pond's total surface was covered with emergent vegetation. This vegetation was largely limited to the southern portion of the headrace pond, near the pond's inlet. Observed emergent vegetation included a mixture of common reed (Phragmites australis, FACW), cattail (T. latifolia, OBL), multiflora rose (Rosa multiflora, FACU), jewelweed (L capensis, FACW), sensitive fern (0. sensibilis, FACW), duck potato (Sagittaria latifolia, OBL), and pickerelweed (P. cordata, OBL). 2.3.2.3 Flag Series 3A (Stony Brook, R5UBH) Stony Brook is a perennial freshwater stream that begins at an outlet of Lower Mill Pond, flows northward to a culvert beneath Stony Brook Road, and continues north out of the project area. Stony Brook is primarily characterized as a channelized fish ladder that facilitates a herring run. The brook forms a large pool (the tailrace pond) immediately upstream of the culvert. The stream forks downstream of the culvert, with the two channels flowing parallel to each other before converging approximately 150 feet downstream. During this split the main channel still operates as the primary fish run and is lined with concrete fish weirs. Vertical stone masonry walls line the banks of Stony Brook, and the streambed is composed of unconsolidated substrate (primarily sand with gravel, cobbles, and boulders present along the stream). 2.3.2.4 Flag Series 3B (Bypass Channel, R5UBH) A former millrace, the existing Bypass Channel dates from the 17th or 18th century and is a perennial freshwater stream formed by a bifurcation of Stony Brook downstream of the culvert. The Bypass Channel runs for approximately 150 feet before rejoining Stony Brook. Stop logs control the volume of water entering the Bypass Channel, which is managed to maintain adequate flow for the Stony Brook fish ladder. A steep drop-off is present on the downstream end of the Bypass Channel before it reunites with Stony Brook. Vertical stone walls demarcate the stream banks. The stream bed is primarily sandy with a mixture of gravel, cobbles and boulders present. The bed is occasionally dredged to maintain the site's historic character and desired water levels to ensure the proper function of the fish ladder. Vegetation present within the stream channel consists of pickerelweed (P. cordata, OBL), soft rush (Juncus Effusus, OBL), devil's beggarticks (Bidens frondosa, FACW), and swamp loosestrife (D. verticillatus, OBL). 2.3.3 Bordering Vegetated Wetlands (BVW) Two (2) Bordering Vegetated Wetlands were identified within 100 feet of the Project Site. Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 2-4 Section 2 Tighe&Bond 2.3.3.1 Flag Series 5A (PSS) This BVW is located to the north of the project area along the right bank of Stony Brook. This is a groundwater -based wetland that is primarily fed by hillside seeps along the slope of the right bank and is classified as Palustrine Scrub Shrub (PSS). Hydrologic indicators include one (1) inch of surface water, a high-water table (zero (0) inches from soil surface), saturation at soil surface, drainage patterns, and water -stained leaves. Commonly identified vegetation observed in the herbaceous layer included jewelweed (1. capensis, FACW, 30%), English ivy (Hedera helix, FACU 20%), skunk cabbage (Symplocarpus foetidus, OBL, 10%), and Virginia creeper (Parthenocissus quinquefolia, FACU, 5%). The shrub layer is composed of multiflora rose (R. multiflora, FACU, 25%), sweet pepperbush (C. alnifolia, FAC 20%), and speckled alder (Alnus incana, FACW, 20%). Woody Vines include the Fox grape (Vitis (abrusca, FACU 60%). Red Oak (Quercus rubra, FACU, 50%) and Norway Maple (A. platanoides, UPL, 10%) comprise the tree layer. Hydric soil indicators include a Sandy Mucky Mineral (S1). 2.3.3.2 Flag Series 6A (PSS) This BVW is also a PSS groundwater -based wetland fed by hillside seeps located across from Flag Series 5A on the left bank of Stony Brook. Hydrologic Indicators include one (1) inch of Surface Water, a high water table (zero (0) inches from soil surface), saturation at soil surface, drainage patterns, water -stained leaves, and a hydrogen sulfide odor. Commonly identified vegetation in the herbaceous layer included Jewelweed (1. capensis, FACW, 50%), sensitive fern (0. sensibilis, FACW, 30%), swamp loosestrife (D. verticillatus, OBL, 15%), and skunk cabbage (S. foetidus, OBL, 15%). The shrub layer consisted of swamp rose (Rosa palustris, OBL, 50%), multiflora rose (R. multiflora, FACU, 40%), and meadowsweet (Filipendula ulmaria, FAC 10%). Fox grape (V. /abrusca, FACU, 10%) was the only woody vine present and Norway maple (A. platanoides, UPL, 10%) was the only tree observed in the tree layer. Soil indicators consisted of Hydrogen sulfide (A4) and Sandy Mucky Mineral (S1). 2.3.4 Banks of or Land under the Ocean Ponds, Streams, Rivers, Lakes, or Creeks that Underlie an Anadromous/Catadromous Fish Run 2.3.4.1 Flag Series 1A (Lower Mill Pond) Flag Series 1A demarcates the limits LUW in Lower Mill Pond. This LUW is part of the larger Stony Brook Fish Run and serves as an important spawning ground for anadromous alewife (Alosa pseudoharengus). 2.3.4.2 Flag Series 3A (Stony Brook) Stony Brook is a perennial freshwater stream that begins at an outlet of Lower Mill Pond, flows northward to a culvert beneath Stony Brook Road, and continues north out of the project area. Stony Brook is primarily characterized as a channelized fish ladder that facilitates the annual herring run for anadromous alewife (A. pseudoharengus). The brook forms a large pool (the tailrace pond) immediately upstream of the culvert. The stream forks downstream of the culvert, with the two channels flowing parallel to each other before reconverging approximately 150 feet downstream. Across this split, the main channel still operates as the primary fish run and contains a series of concrete fish weirs. Vertical stone walls line the banks of Stony Brook, and the streambed is composed of unconsolidated substrate (primarily sand with gravel, cobbles, and boulders present along the stream). Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 2-5 Section 2 Tighe&Bond 2.3.5 Riverfront Area As Stony Brook is a perennial stream and is depicted as such on the USGS quadrangle, it is afforded a 200 -foot Riverfront Area which extends outward from the MAHW line. Riverfront Area associated with Stony Brook is dominated by vertical stone walls, with the upstream limit of the stream demarcated by Lower Mill Pond Dam. Extending horizontally from the stream, this area includes the entirety of the mill complex and the surrounding forested slopes. Upstream of Stony Brook Road, Riverfront Area to the east of Stony Brook is composed of a pervious recreation area, a single-family residence, and undeveloped woodlands. Riverfront Area west of Stony Brook contains the headrace pond, the historic grist mill, a single-family residence, a tennis court, and undeveloped woodland. Lower Mill Pond dominates Riverfront Area south of Stony Brook. Riverfront Area downstream of the Stony Brook Road is dominated by undeveloped woodland on both sides of Stony Brook and the Bypass Channel. 2.4 Rare Species The Massachusetts Natural Heritage and Endangered Species Program (NHESP) (Atlas, 15th edition, effective August 1, 2021, and MassGIS online mapping data (August 1, 2021)) were reviewed during the preparation of this application. According to these sources (Appendix A), the proposed work is located within the limits of mapped Priority Habitats of Rare Species (PH559) and Estimated Habitats of Rare Wildlife (EH543) for the Eastern Box Turtle (Terrapene carolina), as shown on the MassDEP Priority Resource Map and Site Plan (Figure 2 and Figure 3 in Appendix A). Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 2-6 SECTION 3 Tighe&Bond Section 3 Project Description This section provides a description of the proposed repairs and improvements to the headrace pond wall and fishway, protective measures, post -construction site restoration and stabilization and vegetative management of the channel, headwalls, access paths and vegetated fringe. 3.1 Proposed Activities The proposed project involves the stabilization of stone masonry wall that separate the headrace pond and fishway, the repair of the stone masonry walls along the fish pool upstream of Stony Brook Road culvert, and installation of a geosynthetic clay liner (GCL) in the headrace pond. Additionally, the project will include improvements to the existing fishway on the north side of Stony Brook Road to enhance fish passage and vegetative management of the channel, headwalls, access paths and vegetated fringe to provide personnel access and increased fish passage in keeping with the Determination of Applicability issued on February 10, 2021 and approved MassDEP Policy 22-1 Memorandum Fish Run Maintenance ratified by the Brewster Conservation Commission during the March 14, 2023 Commission Public Meeting with additional Special Conditions. See Appendices I, J & K. 3.1.1 Stone Wall Rehabilitation The east headrace stone wall supporting the berm that separates the headrace pond from the fish passage is in distress and requires stabilization. Therefore, the project includes installation of a cast -in -place concrete retaining wall immediately in front of the existing stone wall to mitigate the risk. This stone wall will be faced with decorative "Cape Cod" stone that will be cut to match the size of the existing west headrace pond wall. Stone will be installed with the weathered side facing outward to maintain the current appearance of the wall. 3.1.2 Line Headrace Pond & Repair Walls Hydrostatic pressure caused by infiltration from the headrace pond is a major factor compromising wall stability. Therefore, the project includes the installation of a geosynthetic clay liner (GCL) along the base of the headrace pond to extend the longevity of the historic mill complex and protect the structural integrity of the fishway. The purpose of the GCL along the bottom of the headrace pond is to limit seepage through the earthen berm from the headrace pond to the fishway. Seepage behind the existing fishway stone masonry wall increases detrimental freeze/thaw action which causes frost jacking of stone masonry that leads to unacceptable movement of, and potential failure of the wall. One area on the stone masonry wall along the fishway side of the berm will be repaired in kind. The proposed sequence of steps includes draining the pond by redirecting flow through the fishway, pulling the stoplogs at the downstream end of the pond to drain the majority of the pond, and utilizing pumps to drain the remaining water to allow the sediment to dewater in place to the extent feasible. Sediment will then be excavated as needed to construct the new headrace pond retaining wall and to install the new pond liner. In total, approximately 325 cubic yards will be excavated and stockpiled in the pond to air dry again before being removed from the headrace pond and stockpiled on site. The excavated pond will then be lined with a GCL and backfilled with stockpiled native sediment to restore the original elevation of Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 3-1 Section 3 Tighe&Bond LUW in the pond. Any excess dredge material will be moved offsite and disposed of in accordance with the applicable regulations. 3.1.3 Fishway Improvements Improvements to the fishway are proposed to enhance Stony Brook's carrying capacity of migrating alewife and improve ease of passage. Existing weirs require modification to improve hydraulic performance of the fishway. Consequently, proposed activities require redirecting flow from Stony Brook into the Bypass Channel and replacing the ten existing concrete and field stone weirs in Stony Brook. Additionally, the project includes installation of three (3) new concrete weirs on the north (downstream end) of the existing fishway. Following construction of the weirs, flow will be redirected to pre - construction conditions from the Bypass Channel back into Stony Brook. 3.1.4 Vegetative Management Periodic vegetative management within the channel, headwalls, paths, and vegetative fringe of the fish run is required to provide personnel access and maintain viable fish passage. Proposed maintenance will be conducted by Town staff, volunteers and contractors. This proposed work is in keeping with prior Conservation permit approval, Determination of Applicability issued on February 10, 2021, and approved MassDEP Policy 22-1 Memorandum Fish Run Maintenance ratified by the Brewster Conservation Commission during the March 14, 2023, Commission Public Meeting with additional Special Conditions. See Appendices I, J & K. 3.1.5 Construction Sequence Based upon our experience with similar projects, the general construction sequence is anticipated to include the following steps in this approximate order. • Re -flag wetlands and other sensitive resources adjacent to work areas and access roads; • Pre -construction Work Notification Meeting with the Conservation Administrator • Conduct vegetation management (mowing as necessary); • Establish and Install Best Management Practices ("BMPs"); • Establish staging areas; • Drain the headrace pond; • Dredge the pond bottom; • Install the new headrace pond retaining wall; • Line the pond bottom with a Geosynthetic Clay Liner and cover with dredged materials; • Redirect flow from Stony Brook into the headrace pond; • Conduct fishway wall spot repair; • Re-establish normal flow through the headrace pond and fishway south of Stony Brook Road; • Redirect flow north of Stony Brook Road through the Bypass Creek; • Install cofferdams on the downstream portions of Stony Brook to enable work on fish weirs; Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 3-2 Section 3 Tighe&Bond • Demolish existing fish weirs and replace with new, stone faced cast in place concrete weirs; • Redirect flows from the Bypass Channel back to Stony Brook; • Apply grout to fill voids at downstream end of the Bypass Channel that trap fish; • Via pumps, bypass Stony Brook flows around work area of three new weirs at downstream end of fishway; • Construct three new weirs at downstream end of fishway for improved fishway hydraulics; • Remove bypass pumps and cofferdams and restore flow through Stony Brook; • Restore affected area as necessary, including revegetation of disturbed areas, and conducting follow up inspections, as required. 3.2 Protective Measures The various protective measures that will be implemented prior to and during construction activities are described below. These measures are shown and described on the project drawings provided in Appendix B. 3.2.1 Erosion Control Barriers Erosion control barriers will consist of 12 -inch diameter compost filter tubes placed along the downgradient limits of work. Filter tubes will be staked using a two (2) x two (2) inch wooden stake installed to a minimum depth of 12 inches, to minimize the potential for the migration of disturbed soil. The contractor will be required to maintain the barriers in good working order and to repair and replace sections, if necessary. Upgradient limits of work will be demarcated with orange safety fencing to ensure the contractor is restricted to the project area. A minimum of 50 feet long and six (6) inches deep track out mat, consisting of at least two (2) inches of stone underlain by filter fabric, will be placed at the site entry to minimize soil track out onto Stony Brook Road. 3.2.2 Surface Water Control Since work will occur below the Mean Annual High Water (MAHW) line during construction of both the fishway and the headrace pond, work will occur in phases. First, the headrace pond will be temporarily drained, and flow will be directed through the fishway during construction of the headrace wall. Once this construction phase is complete, flow will be redirected into the headrace pond during repair of the wall separating the fish ladder and the headrace pond. While working north of Stony Brook Road, flow through the fishway will be redirected to the Bypass Channel during construction on fish weirs 1-10 (Appendix B). Temporary cofferdams and bypass pumping will be utilized during construction on Weirs A -C. The type of coffer dam to be constructed shall be left to the discretion of the contractor, but may consist of sandbags, Portadams®, or an equivalent. The Conservation Administrator will be kept notified of the selected coffer dam. Unconsolidated material (e.g. an earthen berm) will not be used for the cofferdams. 3.2.3 Construction Dewatering Once a cofferdam is installed, standard temporary dewatering measures will be required during portions of the rehabilitation work which require excavation or other activities where groundwater may interfere with the work. Construction dewatering discharge to a Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 3-3 Section 3 Tighe&Bond surface water body shall be pretreated for sediment removal by passing through appropriately sized filter bags or a fractionation/sedimentation tank prior to discharge. 3.2.4 Time of Year Restrictions All work will be conducted in compliance with applicable Time of Year ("TOY") construction restrictions as work will occur in a herring run. Current TOY restrictions for Stony Brook are from February 1st to November 15th (Massachusetts Division of Marine Fisheries Technical Report TR-47). All work will be coordinated with the Department of Marine Fisheries ("DMF") and NHESP comments on Special Conditions to ensure the project is in full compliance with these regulatory agencies. 3.3 Post Construction Restoration Following the completion of construction activities, disturbed upland areas within the limit -of -work will be restored. Restoration will include the restoration of topsoil or placement of imported loam as such that a minimum of six (6) inches of suitable material is present and appropriately limed, fertilized, graded, and scarified. Areas within the 100 -foot buffer will be seeded with New England Conservation/Wildlife Mix (Table 3-1) manufactured by New England Wetland Plans, Inc. or and approved equivalent in areas specified by the Brewster Conservation Commission. Where otherwise not specified, disturbed wetland areas will be seeded with "New England Erosion Control/Restoration Mix" for moist sites, as manufactured by New England Wetland Plants, Inc. (Table 3-2), or an equivalent mixture.

The following alternatives were considered for this project. 3.4.1 No Action The no action alternative would entail leaving the headrace wall in poor condition and susceptible to additional deterioration and eventual failure. Continued hydrostatic pressure on the headrace walls will continue to weaken the structures and can potentially lead to the failure of the berm separating the headrace pond from the fish ladder. While the fishway would still be operable without the replacement of existing weirs and installation of three new weirs, it would not result in optimal passage between the spawning grounds to the sea and lower the overall success rate of migrating alewife (A. pseudoharengus). 3.4.2 Replacement of the Existing Headrace Pond Wall Complete replacement of the existing east headrace retaining wall was considered. However, this alternative would require a large excavation into the earthen berm between the headrace pond and the fishway which would compromise the berm and the Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 3-5 Section 3 Tighe&Bond retaining wall along the fishway. Besides being more economical, the proposed approach is safer and has less impact on the berm and fishway. It should be noted that the west headrace retaining wall was overlaid with a new concrete wall with stone facing in a similar manner as currently proposed for the east wall. 3.4.3 Replacement of Fishway Wall with Reinforced Concrete Structure The purpose of the liner along the bottom of the headrace is to limit seepage through the earthen berm from the headrace pond to the fishway. Seepage behind the existing fishway stone masonry wall increases detrimental freeze/thaw action which causes frost jacking of stone masonry that leads to unacceptable movement of, and potential failure of the wall. The alternative would be to replace the fishway stone masonry wall with a reinforced concrete wall. While a new wall could be stone faced similar to other elements at the site, this wall is larger and has more exposed face that will diminish the historical character of the site. Just as important and similar to the headrace pond wall, replacement of the fishway wall would also require a large excavation into the berm between the headrace pond and the fishway which would compromise the berm and the retaining wall along the headrace pond. Besides being more economical, the proposed approach is safer and has less impact on the berm, fishway, and headrace pond retaining wall.

A total of 260 If will be impacted permanently as a result of installing a new headrace pond wall, raising wall elevations, and installation of new fish weirs. This work is not expected to impair the stability or ecological function of the bank. The performance standards for inland Bank are set forth at 310 CMR 10.54 (4)(a) and are addressed below. (a) Where the presumption set forth in 310 CMR 10.54(3) is not overcome, any proposed work on a Bank shall not impair the following: 1. The physical stability of the Bank; This project involves installation of a new wall along the east side of the headrace pond and repairs to the stonewalls along the fishway that function as Bank and is thus expected to improve the overall bank stability. 2. The water carrying capacity of the existing channel within the Bank; This project does not modify the existing dimensions or carrying capacity of the exiting channel within the banks. 3. Ground water and surface water quality; Construction period protective measures (e.g. erosion/sedimentation controls) have been incorporated into project design, as needed, to limit impacts to ground and surface water quality. The site will be revegetated following the end of construction activities and the project is not expected to impact groundwater or surface water quality. 4. The capacity of the Bank to provide breeding habitat, escape cover and food for fisheries; The proposed project is intended to improve the breeding habitat of migrating alewife (A. pseudoharengus) and work will be phased to not significantly impair these habitat functions while construction is underway. Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-2 Section 4 Tighe&Bond 5. The capacity of the Bank to provide important wildlife habitat functions. A project or projects on a single lot, for which Notice(s) of Intent is filed on or after November 1, 1987, that (cumulatively) alter(s) up to 10% or 50 feet (whichever is less) of the length of the bank found to be significant to the protection of wildlife habitat, shall not be deemed to impair its capacity to provide important wildlife habitat functions. In the case of a bank of a river or an intermittent stream, the impact shall be measured on each side of the stream or river. Additional alterations beyond the above threshold may be permitted if they will have no adverse effects on wildlife habitat, as determined by procedures contained in 310 CMR 10.60. This project is focused on previously altered sections of the stream bank and construction will be phased so as to not impair fish passage. Therefore, no adverse effects on the wildlife habitat of the area are expected. To minimize impacts, the project will comply with the aforementioned Best Management Practices (BMPs) and all applicable TOY restrictions. 6. Work on a stream crossing shall be presumed to meet the performance standard set forth in 310 CMR 10.54(4)(a) provided the work is performed in compliance with the Massachusetts Stream Crossing Standards by consisting of a span or embedded culvert in which, at a minimum, the bottom of a span structure or the upper surface of an embedded culvert is above the elevation of the top of the bank, and the structure spans the channel width by a minimum of 1.2 times the bankfull width. This presumption is rebuttable and may be overcome by the submittal of credible evidence from a competent source. Notwithstanding the requirement of 310 CMR 10.54(4)(a)5., the impact on bank caused by the installation of a stream crossing is exempt from the requirement to perform a habitat evaluation in accordance with the procedures contained in 310 CMR 10.60.

A total of 250 If will be impacted permanently as a result of installing a new headrace pond wall, raising wall elevations, and installation of new fish weirs. The proposed work will be conducted to improve the efficiency and long-term viability of the fish run and is thus expected to increase the net productivity of the fish run. This section describes the applicable Fish Run performance standards at 310 CMR 10.35(3) through (5). (3) Any project on such land or bank shall not have an adverse effect on the anadromous or catadromous fish run by: a. impeding or obstructing the migration of the fish, unless DMF has determined that such impeding or obstructing is acceptable, pursuant to its authority under M.G.L. c. 130, § 19; b. changing the volume or rate of flow of water within the fish run; or c. impairing the capacity of spawning or nursery habitats necessary to sustain the various life stages of the fish. Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-5 Section 4 Tighe&Bond The purpose of this project is to improve fish migration. Alterations to the fishway will increase the overall carrying capacity of the fish run. The project will take place outside the fish migration abiding by TOY restrictions. Therefore, the project will have a positive, rather than adverse effect on the fish run. (4) Unless otherwise allowed by DMF pursuant to M.G.L. c. 130, § 19, dredging, disposal of Dredged Material or filling in a fish run shall be prohibited between March 15th and June 15th in any year. This project shall be conducted in accordance with relevant TOY restrictions and in coordination with the DMF so that the fish run is not negatively impacted by construction. (5) Notwithstanding the provisions of 310 CMR 10.35(3), no project may be permitted which will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species, as identified by procedures established under 310 CMR 10.37. While the project site has been identified to include habitat for the Eastern Box Turtle, (T. carolina) the project is being reviewed by the DMF and NHESP to ensure that there will be no adverse effect on the species. Accordingly, the project will adhere to all BMPs and TOY restrictions imposed by NHESP during their review. 4.1.3.4 Riverfront Area Work within Riverfront Area is limited to 5,700 sf of temporary impacts associated with material staging and stockpiling, installation of a construction entrance, and activities associated with the wall repairs.

Where the presumption set forth in 310 CMR 10.58(3) is not overcome, the applicant shall prove by a preponderance of the evidence that there are no practicable and substantially equivalent economic alternatives to the proposed project with less adverse effects on the interests identified in M.G.L. c.131 § 40 and that the work, including proposed mitigation, will have no significant adverse impact on the riverfront area to protect the interests identified in M. G.L. c. 131 § 40. In the event that the presumption is partially overcome, the issuing authority shall make a written determination setting forth its grounds in the Order of Conditions and the partial rebuttal shall be taken into account in the application of 310 CMR 10.58 (4)(d)1.a. and c.; the issuing authority shall impose conditions in the Order that contribute to the protection of interests for which the riverfront area is significant. (a) Protection of Other Resource Areas. The work shall meet the performance standards for all other resource areas within the riverfront area, as identified in 310 CMR 10.30 (coastal bank), 10.32 (salt marsh), 10.55 (Bordering Vegetated Wetland), and 10.57 (Land Subject to Flooding). When work in the riverfront area is also within the buffer zone to another resource area, the performance Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-6 Section 4 Tighe&Bond standards for the riverfront area shall contribute to the protection of the interests of M.G.L. c. 131, § 40 in lieu of any additional requirements that might otherwise be imposed on work in the buffer zone within the riverfront area. Compliance with other resource area performance standards are reviewed in this section of the NOI narrative. The project qualifies for consideration as an Ecological Restoration Limited Project and has been designed to meet performance standards to the maximum extent practicable. (b) Protection of Rare Species. No project may be permitted within the riverfront area which will have any adverse effect on specified habitat sites of rare wetland or upland, vertebrate or invertebrate species, as identified by the procedures established under 310 CMR 10.59 or 10.37, or which will have any adverse effect on vernal pool habitat certified prior to the filing of the Notice of Intent. The project area has been identified as habitat for the Eastern Box Turtle, (T. carolina, (Appendix D). The proposed work is not expected to have any adverse effects on the habitat of rare species and will adhere to all BMPs and TOY restrictions. This NOI is being concurrently submitted to NHESP for streamlined review. No vernal pool habitat was identified at or near the project site. (c) Practicable and Substantially Equivalent Economic Alternatives. There must be no practicable and substantially equivalent economic alternative to the proposed project with less adverse effects on the interests identified in M.G.L. c. 131 § 40. Section 3.4 presents a summary of the alternatives assessment conducted for the project. The proposed work activities were determined to be the most cost- effective method to stabilize the headrace wall and improve the fishway with minimal environmental impacts to Resource Areas. (c) No Significant Adverse Impact. The work, including proposed mitigation measures, must have no significant adverse impact on the riverfront area to protect the interests identified in M.G.L. c. 131, § 40. The project will not result in a significant change in character of or adverse impact to Riverfront Area. The project disturbance focuses on improving the quality of the fishway to promote greater fish passage. To ensure this is the case, the project will comply with the aforementioned BMPs and all applicable TOY restrictions. 4.2 Town of Brewster Wetlands Bylaw 4.2.1 Variance Request As the proposed work will alter existing resource areas protected under the Town of Brewster Wetlands Bylaw, Tighe & Bond requests (3) variances pursuant to Ch. 172 Section 5.01 of the Town's Wetlands Protection Regulations for work in Fish Runs, Banks, and Land Under Water Bodies. Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-7 Section 4 Tighe&Bond The project's proposed mitigation measures, discussed previously in this narrative and specifically applied to the applicable resource areas in the following subsections, are designed to contribute and enhance protection of the resource values in the Town's Wetlands Bylaw. These measures were found to be the best alternative for this project, as described in the alternative analysis in Section 3.4. As such, the proposed work and its natural and consequential effects are expected to have no adverse effect upon the interests specified in the Bylaw and meets the variance provisions described in the Town's Wetland Bylaw and associated wetland regulations. 4.2.1.1 Fish Run The proposed project is being conducted to improve the quality of the fish run to enhance fish passage within Stony Brook. Consequently, the project meets the performance standards set forth in the Town Bylaw §172 2.09 and Town Wetland Regulations §2.09(4): (4) Any activity which is allowed under a variance granted pursuant to Section 5.01 of these regulations on the bank of a fish run, land under a fish run, or land within 50 feet of the bank of a fish run shall comply with the following regulations: (a) Any project on such land or bank shall not have an adverse effect on the anadromous or catadromous fish run by: 1. Impeding or obstructing the migration of the fish; or by causing mortality to adult or juvenile fish; or The project is being conducted in part to enhance migratory fish passage and remove potential impedances and obstructions to migration under existing conditions. 2. Changing the volume or rate of flow of water within the fish run; or The overall volume and flow rate of Stony Brook is expected to remain unchanged by the project. Minor changes to flow velocity within the Fish Run are being incorporated to create deep pools where migrating fish can rest, benefiting the fish, and facilitating easier fish passage. 3. Impairing the capacity of spawning or nursery habitats necessary to sustain the various life stages of the fish. Work being conducted in the Fish Run is designed to facilitate easier migratory passage to the spawning habitat and will not negatively affect the spawning habitat itself. Increased fish passage and survivability would likely lead to increased spawning and recruitment. (b) Dredging, disposal of dredge material or filling in a fish run shall be prohibited. All proposed dredging work will occur within the headrace pond which is outside of the area of the Fish Run. No disposal of dredge material in or filling of the Fish Run is proposed. Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-8 Section 4 Tighe&Bond 4.2.1.2 Inland Bank Proposed work on Inland Bank is being conducted to improve the structural stability of existing manmade structures and will not result in adverse impacts to the natural characteristics of the bank. Consequently, the project meets the performance standards set out in the Town Bylaw §172 3.01 and Town Wetland Regulations §3.01(4): (4) Any activity which is allowed under a variance granted pursuant to Section 5.01 of these regulations on the bank of a fish run, land under a fish run, or land within 50 feet of the bank of a fish run shall comply with the following regulations: (a) Any proposed work on a Bank or within 100 feet of a Bank shall not impair the following: 1. the physical stability of the Bank; The project is being conducted in part to improve the physical stability of the Banks of Stony Brook through repair of its walled sections. 2. the water carrying capacity of the existing channel within the Bank; The project retains existing characteristics of the stream channel and will have no effect on the water carrying capacity of the existing channel within the Banks. 3. ground water and surface water quality; The project is designed such that it will have no impact on ground water and surface water quality. 4. the capacity of the Bank to provide breeding habitat, escape cover and food for fisheries. The existing Banks consist primarily of heavily modified manmade walls and the proposed work maintains these existing conditions. Therefore, the project will result in no significant alterations to the functional capacities of the existing Bank. 4.2.1.3 Land Under Waterbodies Proposed work within LUW includes the installation of fish weirs and the installation of the GCL underneath the headrace pond. Once the GCL is installed, it will be covered with native sediment and the natural bathymetry of the headrace pond will be restored, thus maintaining the pond's functionality as LUW. The installation of the fish weirs and new headrace pond wall will result in approximately 400 sf of loss resource area. The proposed work still likely warrants a variance however, as the installation of the fish weirs will enhance the ability of the fishway to convey migrating alewife to their spawning grounds and work on the headrace wall is needed to enhance the longevity of the historic mill complex and fishway. Consequently, the project meets the performance Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-9 Section 4 Tighe&Bond standards set out in the Town Bylaw §172 3.03 and Town Wetland Regulations §3.03(4): (4) Any activity which is allowed under a variance granted pursuant to Section 5.01 of these regulations on land under a waterbody shall comply with the following regulations: (a) Any proposed work upon land under a waterbody shall not impair the following: 1. The water carrying capacity within the defined channel, which is provided by said land in conjunction with the banks; The proposed work will maintain the existing stream channel characteristics and is designed to have no impact on the carrying capacity of water within the defined channel. 2. Ground and surface quality; The project is designed such that it will have no impact on ground water and surface water quality. 3. The capacity of said land to provide breeding habitat, escape cover and food for fisheries. Following installation of the GCL, the headrace pond will be backfilled with native sediment to restore the pond back to its pre -construction conditions. No loss of capacity to provide breeding habitat, escape, cover, and food is expected from this project. 4.3 Other Regulatory Programs 4.3.1 MA Endangered Species Act The project is subject to the Massachusetts Endangered Species Act (MESA) regulations set for at 321 CMR 10.00, as administrated by NHESP. MESA jurisdiction is triggered by activities proposed within mapped Natural Heritage and Endangered Species Program (NHESP) Priority Habitats of Rare Species and Estimated Habitats of Rare Wildlife for the eastern box turtle. Protective measures are proposed to protect this species at the site. Qualified biologists possessing a Scientific Collection Permit will train contractors performing the work on proper turtle identification and protocols should a turtle be encountered. Additionally, protective barriers will be installed surrounding active work areas in an effort to exclude this species from the work area if work is to occur during their active season (April 1 to November 1). Construction areas will be surveyed for eastern box turtles by the qualified biologist over two non-consecutive days to clear the work area of any turtles if working during their active period. Turtle barriers will be inspected daily and maintained in good condition for the duration of any work that overlaps with their active period following any NHESP and Town of Brewster Conservation Commission TOY restrictions. A copy of the NOI has been sent to NHESP for streamlined review under both the MAWPA and MESA. Notice of Intent Stony Brook Grist Mill Headrace Pond Retaining Wall and Fishway Rehabilitation Project 4-10 Section 4 Tighe&Bond 4.3.2 MA Public Waterfront Act The project falls under the purview of Chapter 91 of the Massachusetts Public Waterfront Act as Stony Brook is a jurisdictional waterway. However, maintenance on headrace walls and fishways are both considered exempt activities (310 CMR 9.05(3)(g) and thus do not require permit authorization. 4.3.3 Sections 404 and 401 of the Clean Water Act This project involves the dredging of the headrace pond during the repair and stabilization of the headrace and fishway walls and thus requires permitting under Sections 404 and 401. 4.3.4 Massachusetts Historical Commission The proposed project includes work in areas known to contain sensitive archeological resources. A Project Notification Form (PNF) will be submitted to the Massachusetts Historical Commission for the proposed work. An inventory of known historic and archeological resources within the vicinity of the proposed project site is included in Appendix H.

Based on the information provided, this project site or a portion thereof is located within the current Massachusetts Natural Heritage Atlas. The following state -listed species are mapped for both Priority Habitat (PH) and Estimated Habitat (EH), as indicated in the following table: Scientific Name Terrapene carolina Common Name Taxonomic Group State Status EH PH Eastern Box Turtle Reptile Special Concern 390 892 The species listed above is protected under the Massachusetts Endangered Species Act (MESA) (M.G.L. c. 131A) and its implementing regulations (321 CMR 10.00). State -listed wildlife are also protected under the Massachusetts Wetlands Protection Act (WPA) (M.G.L. c. 131, s. 40) and its implementing regulations (310 CMR 10.00). Fact sheets for most state -listed species can be found on our website (www.mass.gov/nhesp). Please note that projects and activities located within Priority and/or Estimated Habitat must be reviewed by the Division for compliance with the state -listed species protection provisions of MESA (321 CMR 10.00) and/or the WPA (310 CMR 10.00). Wetlands Protection Act (WPA) If the project site is within Estimated Habitat and a Notice of Intent (NOI) is required, then a copy of the NOI must be submitted to the Division so that it is received at the same time as the local conservation commission. If the Division determines that the proposed project will adversely affect the actual Resource Area habitat of state -protected wildlife, then the proposed project may not be permitted (310 CMR 10.37, 10.58(4)(b) & 10.59). In such a case, the project proponent may request a consultation with the Division to discuss potential project design modifications that would avoid adverse effects to state -listed wildlife habitat. MASSWILDLIFE NHESP No. IR-65047 Page 2 A streamlined joint MESA/WPA review process is available. When filing an NOI, the applicant may file concurrently under the MESA and qualify for a 30 -day streamlined joint review. Please visit our website for filing instructions: www.mass.gov/regulatory-review. MA Endangered Species Act (MESA) If the proposed project is located within Priority Habitat and is not exempt from review (see 321 CMR 10.14), then project plans, a fee, and other required materials must be submitted to the Division to determine whether a Take under the MA Endangered Species Act would occur (321 CMR 10.18). Please note that all proposed and anticipated development must be disclosed, as MESA does not allow project segmentation (321 CMR 10.16). Please visit our website for filing instructions: www.mass.gov/regulatory-review. We recommend that state -listed species habitat concerns be addressed during the project design phase prior to submission of a formal MESA filing, as avoidance and minimization of impacts to state -listed species and their habitats is likely to expedite regulatory review. Please visit our website for more information on how to request a pre -filing consultation with the Division: www.mass.gov/how-to/request-a-pre-filing-consultation This evaluation is based on the most recent information available in the NHESP database, which is constantly being expanded and updated through ongoing research and inventory. If the purpose of your inquiry is to generate a species list to fulfill the federal Endangered Species Act (16 U.S.C. 1531 et seq.) information requirements for a permit, proposal, or authorization of any kind from a federal agency, we recommend that you use the NOAA Fisheries Greater Atlantic Region ESA Section 7 Mapper (https://noaa.maps.arcgis.com/apps/webappviewer/index.html?id=1bc332edc5204e03b250ac11f9914a27) and the U.S. Fish and Wildlife Service's Information for Planning and Conservation website (https://ecos.fws.gov/ipac). If you have any questions regarding this letter please contact Emily Holt, Endangered Species Review Assistant, at Emily.Holt@mass.gov.

Also at this site at various times were a tannery, fulling mill, cobbler, and blacksmith; the brook has been and continues to be a noted herring run. Several late 18th and early 19th century residences nearby would also be included (at least one, on Run Hill Road, was home to a miller associated with the industrial site, but it may he too removed from the core of the district by later construction to be included within the district boundaries), including a 1 738 Georgian house (MHC #84), an 18th century half house (MHC #62), ca. 1800 Federal houses (MHC #s 63 and 67), and a ca. 1840 half cape (MHC #65). Also within the district boundaries would be the Dillingham family burial ground on Stony Brook Road. it is likely that this district has strong prehistoric as well as historic archaeological potential, although the area immediately around the mill has been heavily landscaped at some point in the 20th century and is now a public park. A site visit wilt be necessary to confirm boundaries and to determine whether the district should exten up Run Hill Road and east along Stony Brook Road as far as Paine Hollow Road, Massachusetts Cultural Resource Information System Scanned Record Cover Page Inventory No: BRE.L Historic Name: Stony Brook Gristmill Common Name: City/Town: Brewster Village/Neighborhood: West Brewster; Local No: Year Constructed: Use(s): Grist Mill; Museum; Park; Significance: Archaeology, Historic; Architecture; Industry; Recreation; Designation(s): Building Materials: Demolished No The Massachusetts Historical Commission (MHC) has converted this paper record to digital format as part of ongoing projects to scan records of the Inventory of Historic Assets of the Commonwealth and National Register of Historic Places nominations for Massachusetts.

L BRE.66 n Recommended for listing in the National Register of Historic Places. If checked, you must attach a completed National Register Criteria Statement form. ARCHITECTURAL DESCRIPTION This form was prepared at the request of the MHC to document changes made by the Town of Brewster as part of the rehabilitation of the Lower Mill Pond Dam and Fish Ladder in April 2013. The form expands on an existing inventory form for the Stony Brook Gristmill (BRE.66). The Stony Brook Gristmill property occupies a triangular -shaped, approximately 0.66 -acre lot located at the western end of the town of Brewster on Cape Cod in Plymouth County, Massachusetts at 830 Stony Brook Road. It is bound to the north by Stony Brook Road, to the south by Lower Mill Pond, and to the east and west by privately owned, predominantly wooded lots. The property is a small-scale, restored, late -nineteenth-century water -powered mill complex anchored to the south by a mill pond dam (Photographs 1, 2 and 3). The complex is generally divided into two parts. While the western half contains water power infrastructure for gristmill, the eastern half primarily consists of a fish ladder that supports the movement of anadromous fish. To the southeast of the fish ladder are remnants of the original borrow pit that was, according to local historians, used to provide the fill for construction of the original dam is located in the southeast corner of the property on the edge of a steep hill (Condit 2012). Circulation through the site consists of a dirt loop path leading from a brick patio at the northwestern corner of the gristmill around the perimeter of the property. A second path bisects the northern end of the loop path. Three simple wood plank bridges (ca. 1941; repaired 2013) allow pedestrians to cross the northern and southern ends of the various water features. The Stony Brook Gristmill (BRE.66; Photograph 4) is a rectangular, side -gabled, two-story, three -bay by two -bay, wood frame building constructed in 1873 in a vernacular style of architecture. Located in the northwest corner of the parcel, the mill faces northeast towards Stony Brook Road. The building has a wood shingle roof and siding, wood corner boards and rests on a mortared fieldstone foundation that was constructed in 1665 to support a fulling mill on the site. Fenestration is regular with predominantly 6/6, double -hung, wood sash windows and entries consisting of wood plank doors with iron strap hinges set within simple wood frames. The mill is powered by water from the Lower Mill Pond, the headwaters of Stony Brook. The Lower Mill Pond Dam (Photograph 5; reconstructed in 2013) impounds the pond at the reservoir's north end. The dam is an approximately 45 - foot -long and two -foot -wide concrete structure sheathed in mortared fieldstone veneer. Water exits the impoundment through two outlets. On the west side of the dam, water flows through the Lower Mill Pond Dam Gate (Photograph 6, replaced 2013), a steel, welded, vertical -lift head gate in a metal L -channel gate frame. On the east side of the dam, water also flows through a second opening, a concrete spillway weir (reconstructed in 2013) that leads to a fish ladder, discussed below. Water from the Lower Mill Pond Dam Gate flows into the Water Wheel Holding Pond (Photograph 7), which is retained at its north end by the Water Wheel Holding Pond Dam (Photograph 8). This generally oval -shaped, mortared, stone -lined basin acts as a forebay for the mill. The Holding Pond Dam (reconstructed in 1995) is a low concrete structure topped with courses of fieldstone and fitted with two openings. On the west side of the dam, a rectangular opening directs water to the mill wheel via the Box Flume (Photographs 8 and 9), (reconstructed in 1995) which is mounted on a wood trestle. On the east side of the dam, the water flows through a waste gate into a narrow Stone -Lined Channel (Photographs 8 and 2), constructed after 1950. The water from both the channel and water wheel continue to flow into the Stony Brook Mill Catch Basin (Photograph 9) (reconstructed in 1968), an irregularly shaped, stone -lined body of water immediately south of Stony Brook Road. The flume brings water to the Water Wheel (Photograph 9, reconstructed 1964), a wood breast Continuation sheet 1 INVENTORY FORM A CONTINUATION SHEET MASSACHUSETTS HISTORICAL COMMISSION 220 MORRISSEY BOULEVARD, BOSTON, MASSACHUSETTS 02125 BREWSTER STONY BROOK GRISTMILL Area Letter Form Nos. L BRE.66 wheel mounted in cast metal bearings. The east bearing rests on a reconstructed concrete masonry pier (rebuilt in 2010) sheathed in locally supplied fieldstone. On the east side of the Lower Mill Pond Dam, the Lower Mill Pond Spillway Weir (Photograph 10) allows water to flow into the narrow, stone -lined Fish Ladder (Photographs 11 and 12) that contains small, intermittently spaced weirs (all either repaired or replaced in 2013) allowing anadromous fish to ascend the channel to the pond above the dam. The stonework in the southern portion of the fish ladder (relocated eastward around 1968) is mortared, while that of the northern portion is dry -laid. The water flows through the fish ladder into the circular stone -lined Catching Pool (Photograph 13), where migrating fish can pause before climbing the fish ladder. HISTORICAL NARRATIVE In the late -seventeenth century, Stony Brook in West Brewster was identified as an ideal location for mills due to a drop in elevation between the brook's headwaters at local ponds and Cape Cod Bay. Over the course of time, five mills were constructed along this stretch of the brook, which came to be known as Stony Brook Factory Village. The first dam constructed in the village was an earth and stone structure built on the north side of the present-day road alignment. It is likely that shortly afterward, the Upper and Lower Mill Ponds and an earth and stone dam, which came to be known as the Lower Mill Pond Dam, were constructed just south of Stony Brook Road. Local historians state that the original Lower Mill Pond Dam was formed using earth from a borrow pit on the eastern boundary of the dam (Jenkins 2000; Condit 2012). The earliest identified building on the present-day Stony Brook Gristmill property was a fulling mill constructed in 1665 by property owner Kenelm Winslow and his son with the help of local residents John Dillingham, Dillingham's son, and Joseph Wing. Until the late -nineteenth century, the property remained under ownership of the Winslow family, who continued to develop Stony Brook for milling purposes. In addition to the fulling mill, the Winslows constructed a gristmill in the late -seventeenth century and a tannery in 1830 across Stony Brook Road along the eastern bank of the brook (Condit 2012; Ellis 1980; Jenkins 2000). On June 6, 1871, a major fire destroyed the Winslow gristmill and tannery. By this time, Stony Brook Factory Village had been affected by a region -wide industrial decline attributed to the development of Cape Cod Central Railroad (1865- 1938), which put local industries out of business as it made cheaper, mass-produced goods from other areas more readily available. Despite this decline, agricultural activity continued to provide a need for local gristmills. Following the fire, property owner William Winslow sold the land south of Stony Brook Road to Bartlett Winslow and T.D. Sears, who subsequently constructed the Stony Brook Gristmill (BRE.66; BRE.HA.10) in 1873 (Jenkins 2000; Jenkins 1995; Ellis 1980; Stackheim 1969). Operation of the Stony Brook Gristmill was short lived and little is known of its history. J. Howard Winslow, likely a relative of William Winslow, has been identified as the first possible miller, while Benjamin Ellis, according to his son, was the last to grind corn on a regular basis. The gristmill was subsequently used for a variety of purposes including as a dwelling and for the manufacture of overalls, ice cream, and electricity until the early twentieth century. Photographs taken during this period reveal an attached, enclosed wheelhouse on the southeast elevation. In the 1880s, a metal turbine replaced the waterwheel within the existing wheelhouse. Around 1908 Valentine B. Newcomb and his partner A. Percie Newcomb of the Stony Brook Cranberry Company took title to the property and its water privileges. The Newcombs soon leased the mill to Andrew C. Hastings of Cape Cod Yarns, Inc. By 1926, after receiving complaints from cranberry growers that their water source was being interrupted, Hastings ceased use of the mill and invested in the construction of a wooden fish passage to Lower Mill Pond on the property. The gristmill wheelhouse was removed the following year (Jenkins 2000; Jenkins 1995; Ellis 1980; Stackheim 1969). Continuation sheet 2 INVENTORY FORM A CONTINUATION SHEET MASSACHUSETTS HISTORICAL COMMISSION 220 MORRISSEY BOULEVARD, BOSTON, MASSACHUSETTS 02125 BREWSTER STONY BROOK GRISTMILL Area Letter Form Nos. L BRE.66 A community -wide vision of citizens, town officials, and civic and business leaders resulted in the development of the Stony Brook Gristmill property as a local industrial heritage site. The effort was spearheaded by property owners A. Percie Newcomb and Valentine B. Newcomb, who turned down a private bid of $5,000 in order to sell the land for $2,200 to the Town of Brewster on April 15, 1940. The town appropriated $1,000 and private donors presented the town with $1,200. Following the Newcomb's transaction, a second property located directly across the street from the Stony Brook Gristmill was also sold to the town. At the time, this property, owned by Arthur W. Hart, contained the remains of the Abraham Winslow House. Today, these remnants are no longer extant. The town subsequently combined the two properties, transforming the land into a historical and recreational attraction, the "Stony Brook Mill Sites," that would be maintained by a committee consisting of town selectmen and other individuals appointed by the town moderator. The site has been identified as "one of the first successful historic preservation efforts on Cape Cod" (Jenkins 2000). On June 22, 1940, the Brewster Mill Sites, consisting of the Stony Brook Gristmill site and the adjoined Abraham Winslow House property, officially opened. That summer, over 2,000 visitors from 29 states were recorded. In the 1940s, the town made several improvements to the property for the purpose of providing public access, interpretation, and safety. Work included clearing underbrush, laying out unpaved footpaths, installing wood benches and bridges, restoring the mill building, erecting interpretive signage, and repairing the dam, which was leaking and deteriorating. In 1941, a new catching pool was constructed under supervision of the State Department of Conservation. Between 1946 and 1947, the Stony Brook Gristmill was wired for electricity. At some point between 1940 and 1964, the turbine was removed from the gristmill. A new and slightly smaller replica of the original water wheel was installed in 1964. In 1968, the Town of Brewster Alewife Committee implemented the relocation of the herring run fish ladder and reconstruction of the Water Wheel Holding Pond Dam. The southern end of the fish ladder was relocated slightly east and reconstructed with in -kind materials around 1995 and the wood box flume that conveys water from the holding pond to the water wheel was reconstructed to resemble an earlier flume shown in historical images (Jenkins 2000; Condit 2012). The property was first listed in the National Register of Historic Places in 1995 as a contributing resource to the Brewster Old King's Highway National Register Historic District (BRE.G), which was found to be significant at the local, regional, and state level for its close ties to "most of the important persons and events that have shaped Brewster's unique character and heritage" between 1650 and 1945 (Jenkins 1995). In 2000, the property was again listed in the National Register as part of the Stony Brook/Factory Village Historic District (BRE.J), which was found to be significant at the local level under Criteria A, C, and D with a period of significance from 1660 with the establishment of the original Gristmill to 1948, when the industrial heritage of the area was consciously recognized and preserved by the community at large (Jenkins 1995; Jenkins 2000; Ellis 1980; Stackheim 1969). Between 2010 and 2013, the site, now known as the Stony Brook Factory Village Gristmill and Museum, was substantially rehabilitated. In 2010, the pier supporting the water wheel was reconstructed using stone purchased from a local supplier. By late 2011, the Massachusetts Department of Conservation and Recreation's Office of Dam Safety had determined that the Lower Mill Pond Dam was deficient, with an overall physical condition rated as Poor. Portions of the stone fish ladder upstream of Stony Brook Road were also cited as deficient. The Town of Brewster, with funding from NOAA and assistance from Tighe and Bond Consulting Engineers, completed a rehabilitation of the Lower Mill Pond Dam and Fish Ladder. NOAA consulted with the Brewster Historical Committee, Old King's Highway Regional Historic District Commission, and the Massachusetts Historical Commission to identify potential adverse effects to the historic property that could result from the rehabilitation and to develop appropriate designs that would maintain the historic and aesthetic appearance of the site. The dam was replaced with a new, similar structure and the Lower Mill Pond Dam Gate; a steel, bolted vertical -lift head gate in a metal L -channel gate frame; was replaced with a welded gate of similar design. A concrete gate with a semi -permanent wooden face and frame to control water level on the eastern half of the dam was replaced with a cast -in -place concrete Lower Mill Pond Spillway Weir. Certain weirs within the fish ladder were either repaired or replaced in -kind. Fencing, pedestrian bridges, signage, and benches were temporarily removed and replaced. All vegetation was removed and the land was re -seeded. The completed rehabilitation project improved the condition of the dam in accordance with Massachusetts dam safety regulations, maintained the historic and aesthetic appearance of the dam, and protected the river herring run on Stony Brook (Brewster 2012).

Polito Martin Suuberg Lieutenant Governor Commissioner April 27, 2022 Daniel McKiernan, Director Massachusetts Division of Marine Fisheries 251 Causeway Street Suite 400 Boston, MA 02114 Dear Director McKiernan, I am pleased to announce that MassDEP has recently adopted (and attached) a new policy to help the Massachusetts Division of Marine Fisheries (DMF) improve fish runs and protect marine fisheries. The Wetlands Program Policy: Diadromous Fisheries Stream Management responds to concerns raised by DMF regarding the need for performance standards to prevent impediments to fish migration, maintain stream flows within fish runs, and preserve spawning or nursery habitats. The policy incorporates the 2016 DMF Stream Maintenance Protocols and provides further guidance for conservation commissions when reviewing stream maintenance projects to improve fish runs. The policy provides standards of review commensurate with the level of activity proposed in stream channels. The policy encourages minor stream maintenance efforts to protect marine fisheries, including elimination of obstructions to improve surface flows, reduction of debris jams, and promotion the natural scour function of streams to reduce invasive plant growth. Special thanks to Brad Chase of your staff for his assistance in the development of this policy. I anticipate that this policy will provide the necessary guidance for conservation commissions to help expedite DMF's effort to improve fish runs in the 46 coastal communities, and approximately 150 diadromous fish runs, in the Commonwealth. Sincerely, -4J(&z__ Lisa Rhodes Wetlands Program Chief This information is available in alternate format. Contact Glynis Bugg at 617-348-4040.

Supersedes Policy: None Approved by: Stephanie Moura, Director - Wetlands and Waterways Division Purpose: This policy sets forth the Department's standards for stream maintenance associated with Massachusetts Division of Marine Fisheries (DMF) sponsored diadromous fisheries. Statutory and Regulatory Background MGL c. 131, s. 40: Wetlands Protection Act ("Act") and 310 CMR 10.00. M.G.L Chapter 130 §19 Marine Fish and Fisheries Diadromous Fisheries Management MassDEP supports the maintenance of anadromous/catadromous (diadromous) fish runs which are significant to the protection of marine fisheries, an interest protected under the Wetlands Protection Act (M.G.L Chapter 131 §40). The DMF is authorized pursuant to M.G.L Chapter 130 §19 to maintain passageways for diadromous fish in the Commonwealth of Massachusetts. DMF routinely provides related guidance to property owners and municipalities on the proper methods for maintenance of stream channels to allow safe and efficient fish passage. Standards of Review Banks of or Lands that underlie a diadromous fish run are significant to the protection of marine fisheries (310 CMR 10.35). Any project on such banks or land shall not have an adverse effect on the fish run by 1) impeding or obstructing the migration of fish, 2) changing the volume or rate of flow of water within the fish run, or 3) impairing the capacity of such banks or land in providing spawning or nursery habitats necessary to sustain the various life stages of the fish. Historically, stream channel maintenance was typically conducted by municipal herring wardens and had been limited to hand cutting vegetation and debris removal that offered enough relief from channel obstructions to allow fish passage. More recently, incentives and municipal funding for herring wardens have diminished, contributing to a loss of continuity and familiarity with stream maintenance practices. This loss of consistent stream maintenance has led to the obstruction of passageways in some rivers caused by native and invasive vegetation overgrowth, sedimentation, and jams caused by debris and tree falls. DMF has developed standards for stream channel maintenance to provide safe and efficient passage for diadromous fish. In general, these standards recommend Fall (October to mid -December) and Winter (February to mid -March) inspections of stream channels. Streams that are prone to debris accumulation should be inspected on a more frequent basis. Significant obstructions or impediments to the fish run can be removed during the spring diadromous migratory period following consultation with DMF. MassDEP has determined that certain stream maintenance activities are beneficial to the protection of marine fisheries. This Policy sets forth the different levels of review, deemed necessary by MassDEP, for the stream maintenance activities, depending on the scale of the project: 1. Two types of stream channel maintenance projects should be considered to have negligible wetland impacts. A. First are projects that include work done by hand, or by means of hand tools (e.g., saws/clippers). Such projects include the removal of debris, tree fall jams, or other vegetative obstructions to fish migration to improve stream flow and to enhance spawning or nursery habitats. Any dead wood that is part of a debris jam should be placed where the water meets the bank to provide bank structure and habitat. Stream channel maintenance measures are limited to Banks of or Land under streams that underly an Anadromous/Catadromous Fish Run. B. Second are projects that involve maintenance of existing fishway structures. This maintenance would include fixing boards in weirs, patching and pointing repairs of concrete fish channels, or other minor repairs to fish ladders. These activities would likely result in no impacts to the wetland resource areas. Provided the projects outlined in paragraphs A & B comply with the Stream Maintenance Criteria listed in this Policy, the activities should be considered as having negligible impacts and may proceed without additional review under the WPA. 2. Stream channel maintenance work to improve fish runs that involves replacement of existing small wood or aluminum fish ladders, repair of concrete fish ladders, or other activities designed to improve stream flow and fish passage, and do not require substrate excavation, should be reviewed under a Request for Determination of Applicability. In general, MassDEP supports these maintenance projects because they contribute to the protection of fisheries without foreseeable alterations to wetland resources. The MassDEP presumes these activities will further the goals of this policy provided the conservation commission agrees that the activity constitutes work to an existing structure identified in DMF's published survey of diadromous fish passages and the project otherwise complies with the Stream Maintenance Criteria listed in this Policy. 3. MassDEP recommends that a Restoration Notice of Intent be filed for stream channel projects involving new construction, reconstruction, and/or replacement of fish ladders (other than existing wood ladders), in -stream dredging, or other activities involving the use of heavy equipment. Stream Maintenance Criteria: MassDEP supports diadromous fisheries stream channel maintenance provided the following criteria are met: • The work is undertaken by DMF, DMF is a cooperating agency for the work, or the work is directly supervised by DMF. • Work is undertaken pursuant to a DMF-approved Stream Management Plan. • Written notice to the conservation commission is provided 30 days prior to the work and DMF addresses reasonable requests related to the project. • The work is subject to time -of -year restrictions of April 1 to May 31 for river herring runs and March 1 to May 31 for locations with brook trout or rainbow smelt present unless otherwise allowed in a specific DMF-approved fisheries management plan for a particular watercourse or to remove a significant obstruction to fish passage following DMF approval. • The project is designed to maintain stream flow sufficient to sustain diadromous fish passage and promote stream heterogeneity (e.g., stream riffles) and channel morphology. • Live vegetation removal is limited to mid -channel rooted vegetation or snag debris that threatens to reduce water flow or impede fish passage, or that has the potential to reduce water flow or impede fish passage with further growth and debris accumulation. Root masses in the stream channel can be considered for removal if their continued growth could threaten fish passage or encourage channel braiding. • In -channel maintenance is limited to the removal of trash, debris and tree falls that can directly impede and block fish passage. • Any realignment of displaced stones at existing weirs provides backwater shallow channels to assist fish passage. • All stream maintenance is conducted by hand (i.e., saws and clippers). • Cutting of riparian vegetation and stream canopy is minimized to preserve overhanging branches which shade the stream channel, moderate stream water temperatures, and inhibit algal growth. • Stream bank growth is preserved, or minimally disturbed, except in rare cases such as the uprooted trunks of large caliper trees that can destabilize and erode banks leading to diversions from main stem flow. • Mowing of stream banks is prohibited. • Removal of dead vegetation debris is limited to that which impedes fish, impinges fish, or encourages additional accumulation of stream obstructions. Logs or stumps within stream banks may enhance river habitat and should be altered only as necessary to provide fish passage. Strategic bank and near -bank placement of woody debris instead of removal should be considered in all stream maintenance plans. Stephanie Moura Director Wetlands and Waterways Division CHARLES D.

POLITO Lt. Governor KATHLEEN A. THEOHARIDES Secretary RONALD 5. AM1DON DANIEL I_ MCKIERNAN Commissioner Director MEMORANDUM Stream Channel Maintenance for Diadromous Fish Passage To: Brewster Conservation Commission From: Bradford Chase, MA DMF Date: December 10, 2020 Location: Stony Brook, Brewster The Massachusetts Division of Marine Fisheries (MA DMF) regulates the passage of diadromous fish in Massachusetts' coastal rivers and provides guidance to property owners and municipalities on the maintenance of passageways. The relevant authorities include M.G.L Chapter 130 §19 on maintaining sea - run fish passage, the Wetlands Protection Act (WPA), and Massachusetts regulations (principally CMR 310 10.35). The recommended actions are focused on manual vegetation cutting and debris removal and designed to offer enough relief from channel obstructions to allow fish passage with no impedance of natural resource functions or WPA performance standards. Further, we support the tradition of Towns using the process and authority of M.G.L Chapter 130 §94 to enable Town -appointed Herring Wardens to maintain passageways with technical support from MA DMF. The WPA provides Conservation Commissions with authority to regulate activities within 100 ft. of wetlands and streams. In recent years, the approach for local maintenance of river herring runs by Town officials has included Conservation Commission approval through a Determination of Applicability or administrative processes. Town officials charged with marine resource management and enforcement responsibilities can access private property to reach the waterways and tidelands of the Commonwealth. Coordination is recommended with private property owners to reach an agreeable consensus on stream access, especially if volunteers are used. If access is contested, MA DMF is available to consult with the private property owner to describe their responsibility to provide passage for sea -run fish in Massachusetts and the benefits of working cooperatively with Town officials to achieve this goal. This memorandum was prepared for your Commission's review and to assist mutual interests in natural resource management. Stony Brook Stream Channel Maintenance Plan Area of Work. The Stony Brook Watershed has several locations that needs annual attention to support the migratory path of diadromous fish. The Brewster Natural Resources Department is the primary Town Department to annual address stream maintenance in the following stream sections: 1.) Stream channel inspection north of the Stony Brook Mill to tidal zone. 2.) Channel inspection, periodic sediment removal from fishway pools, seasonal installation and maintenance of electronic fish counter, and vegetation removal from stone retaining walLs at Stony Brook Mill. 3.) Hand digging of excess sediment accumulation, gabion repair, and vegetation removal in channel between Lower and Upper Mill Ponds. Important to keep Phragmites in check with hand cutting and to schedule fall inspections for juvenile herring emigration. 4.) Inspect narrows between Upper Mill Pond and Walkers Pond annually. Remove debris jams and wetland shrubs that threaten to close narrows. 5.) Inspect channel from Walkers Pond to Slough Pond to remove debris jams from culvert and channel. Consideration should be made in low flow years to screen off entrance to channel to prevent adult herring from spawning in Slough Pond with subsequent poor juvenile herring survival. If temporary screen is installed is will require weekly inspection during spring and removal by July 15t. 5.) Inspect channel from Walkers Pond to Elbow Pond. Consider if fish passage is possible, and as needed, remove debris from channel and inspect for road stormwater issues. 6.) Inspect channel from Slough Pond to Pine Pond. Consider if fish passage is possible, and as needed, remove debris from channel and inspect for road stormwater issues. 7.) Inspect channel from Long Pond to Greenland Pond. Remove debris and jams from channel and culvert pipe. Coordinate with Town of Harwich Department of Natural Resources on water surface elevation management at Long Pond outlet and develop targets based on staff gauge data. 8.) Coordinate with Town of Harwich DNR on fish passage from Long Pond into Blacks Pond. Remove debris from fishway and hand dig sand accumulation as needed. 9.) Coordinate with Town of Harwich DNR annually on fish passage from Long Pond into Mill Pond (Girl Scout Pond). Remove debris from fishway and hand dig sand accumulation as needed. Participants. Approval of this plan by the Brewster Conservation Commission allows Town of Brewster staff, led by the Natural Resources Department, and appointed volunteers to conduct stream channel maintenance in the Stony Brook watershed. Season. Two periods should be targeted for annual work in stream channels to remove passage impediments to migratory fish: the fall (October to mid -December) to identify obstructions and conduct maintenance, and winter (February to early March) to continue work before the spring fish runs. This approach allows for a second round of work if dense growth or large fallen trees are found at early visits. Monthly inspections are recommended during the migratory period of March 1st to June 30th for river herring and American eel; however, in -water work should be minimized to essential actions. The summer can be a third option given the availability of seasonal labor and the value of low -flow maintenance for juvenile fish emigration: however, this is not always optimal given the summer heat and high plant growth. Methods. In -channel maintenance should be limited to removal of trash and debris that can directly impinge and block fish, and mid -channel rooted vegetation that threatens to reduce water flow, snag debris, or impede fish passage. Hand tools, saws. and clippers are suitable for most conditions. Chainsaws can be used occasionally for large tree falls. The cutting of riparian vegetation and stream canopy should be limited. The riparian buffer provides value for a wide range of aquatic life and the canopy is important to provide wildlife habitat, shade the stream and reduce access for predators of diadromous fish. Live Vegetation Removal. Enthusiasm can often lead to more live vegetation removal than necessary. Care should be taken to remove only live vegetation that can limit fish passage or has that potential with higher growth and debris accumulation. Root masses in the stream channel can be considered for removal if their continued growth could threaten fish passage or encourage channel braiding. Stream bank growth, including large caliper trees. has ecological value and should not be removed unless their presence in the channel could directly impede fish passage or cause significant bank erosion. Dead Vegetation Removal. As described above, vegetation debris that can impede or impinge fish or encourages additional accumulation can be removed. Stream bank logs and stumps can provide valuable habitat for other aquatic resources and should be altered only as necessary to provide fish passage. Sediment Management. Road crossings should be inspected with each winter visit and accumulated sediment and bank erosion should be noted. If sand accumulation threatens passage by reducing water depth, the excess sand should be removed by hand using shovels. Observations of sedimentation and erosion should be noted and reported to the Conservation Commission to assist future management efforts. Brook Trout Presence. Native brook trout are not known to be present in the watershed. Channel Improvements. The movement of large rocks and cobble occurring naturally in the stream is allowed during stream maintenance. The purpose should be to reduce passage impediments, and to create in -stream weirs when necessary to improve water velocity and depth to assist fish movements. Documentation. A log of inspection and stream maintenance activities should be recorded and include dates of inspections, summaries of activities, and observations of the presence of diadromous fish, noteworthy flora and fauna, invasive plants, and observations of issues that may need future attention. Safety Practices. Stream maintenance work should be conducted by coordinated teams and not with individuals working alone. For deeper stream channels, waders with wader belts should be wont Plan Status. The plan was reviewed by the Brewster Conservation Commission on 1/26/21, DMF Coordination. MA DMF fully supports the practice of annual stream maintenance to sustain diadromous fish passage during their obligatory migrations. We published stream maintenance protocols in 2016 to guide local efforts on this important resource management practice: http:llwww.mass. govleealdocsldfg/dmf/pro gramsandproj ectslmdmf-guidelines-for-stream-maintenanc e- final-2016.pdf . Our DMF Fishway Crew is available to assist local efforts and plan partners on all matters related to diadromous fish in the Stony Brook Watershed.

In 1940, the Town of Brewster purchased the abandoned mill and surrounding property for $1,000 and established the Millsites Committee to oversee this important historical site. This area is also the site of Brewster's Herring Run — where every spring countless alewife (herring) make their way up Stony Brook to return to the freshwater ponds where they were born in order to spawn. Since the mill's purchase in 1940, upkeep of the property has required extensive effort. The purpose of the document is to demonstrate all historic maintenance currently ongoing. Stony Brook Road divides the property in half. For clarity, this document will separately address the property North of Stony Brook Road and South of Stony Brook Road.

PROFESSIONAL ENGINEERING, LAND SURVEYING & ENVIRONMENTAL SERVICES Site Development • Property Line • Subdivision • Sanitary • Land Court • Environmental Permitting April 4, 2024 J MO -3831C Brewster Conservation Commission 1657 Main Street Brewster, MA 02631 RE: NOTICE OF INTENT— PROPOSED RENOVATIONS 2740 Main Street, Brewster, MA Assessor's Map 90, Parcel 207 APPLICANT: Scadinative Cape Cod, LLC Dear Commission Members, On behalf of our client, Scandinative Cape Cod, LLC, J.M. O'REILLY & ASSOCIATES INC., is requesting the Brewster Conservation Commission review and approve an Order of Conditions for the construction of an addition to the existing commercial building. The addition is being proposed as the existing spa operation is looking to include a therapeutic component to the existing spa activities. The proposed project includes an exterior treatment pool, a patio area with walkways and landscape improvements. Along with the offices of J.M. O'REILLY & ASSOCIATES, the project team includes architectural firm of S3 Designs and the landscape design services of LeBlanc Jones Landscape Architects. The enclosed submission package includes copies of the Proposed Site Plan, a landscape plan (3 sheets) and the schematic building plans (1 sheet) all of which outline the proposed improvements to the parcel. Wetland Resources: The wetland resource associated with the parcel is a Bordering Vegetated Wetland (BVW) located to the south of the parcel. The edge of the resource has been delineated by Paul Shea of Independent Environmental Consultants. The wetland has been flagged with flagging Al to A7 which were used to establish the 50 and 100 -foot Buffer Zones. Please refer to the enclosed IEC letter, dated 9-20-2023, for additional information. Please refer to the Site Plan for the location of the flagging and the associated Buffer Zones. NO work is proposed within the Resource or within the 50 -foot Buffer to the resource. All proposed activity is within the 50 to 100 foot Buffer Area. 1573 MAIN STREET, P.O. BOX 1773, BREWSTER, NIA 02631 ' PHONE: (508) 896-660I • FAX: (5o8) 896-6602 W W W.JMOREILLYASSOC.COM 2 The locus property has a 3 to 4 foot high fence which runs along the southern portion of the parcel. The Spa has limited their ongoing landscape activities up to the existing fence. It is the understanding of our office that the area to the south of the fence and beyond has been mowed for many years by the owner of the abutting land to the south and east, 2750 Main Street, Parcel 202. The owner of 2750 Main was the previous owner of the spa property. The project proposes no activity in the area beyond the existing fence. Project Narrative: The Applicant proposes to construct a 2,715 sf addition to the existing commercial building. The addition will include therapeutic areas as associated with the spa operations. The majority of the addition is on the existing parking area at the rear of the building. The remainder of the addition is proposed within the existing lawn area. In connection with the addition, the project proposes an exterior treatment pool. The exterior pool is connected to the addition by a patio area. The patio pavers extend to the south with the proposed walkway on the south side of the addition. The walkway serves as an emergency access point for the exterior pool. The project also includes a new eastern entrance walkway towards the front of the building. The eastern walkway replaces the handicapped ramp and results in a reduction of pavement. The project is subject to the Massachusetts Stormwater Requirements. The Brewster Stormwater Regulations indicate the project triggers a Minor Stormwater Permit, please refer to the Site Plan. The Minor Permit Application will be submitted to the building department as part of the building permit process. The requirements of the MA Stormwater Regulations well exceed the requirements of the Brewster Minor Stormwater Permit. Please find enclosed as part of the NOI application the Stormwater Checklist, Stormwater Report and O&M Guidelines and the HydroCAD calculations. The landscape plan involves the removal of several large trees to the west of the building. Please refer to the existing condition plan for the tree locations. There are three trees within the 100 foot Buffer that are proposed to be removed. The Applicant engaged the Bartlett Tree Company to evaluate the conditions of the trees within the Buffer. The existing trees to be removed from the Buffer include a Black Cherry (16"), a Red Maple (10") and a Black Locust (10"). Bartlett has indicated all three trees are showing signs of deterioration and recommend their replacement. The landscape Plan calls for a total of twelve (12) trees; 2 Red Maples; 5 eastern red cedars and 5 Grey Birch, within the 100 -foot Buffer. The shrub community among the trees is dominated by invasive species such as honeysuckle and bittersweet. The landscape proposal is to replace the invasive species with native shrubs and the previously mentioned trees. The native shrubs include a mixture of Winterberry, Sweet Pepperbush, Inkberry and Northern Bayberry. A total of nineteen shrubs are proposed to be SCANDINATIVE CAPE COD, LLC 2740 MAIN STREET BREWSTER, MA NOTICE OF INTENT APRIL 4, 2024 JMO-3831C 3 planted within the 100 -Buffer. The remainder of the area will be planted with a conservation seed mix. Please refer to landscape plan for additional information and details. The limit of work line for the project is proposed to be a row 9 -inch straw wattles. The straw wattles will serve as erosion controls during construction and while the proposed vegetation becomes established. A secondary row of straw wattles is proposed along the edge of the existing pavement, adjacent to the exiting stone swale. The wattles will protect the stone swale from impact due to construction activities. The contractor will be charged with the inspection and repair of the straw wattles during the construction phase. Please refer to the Site Plan for the limit of work details and notes. To protect the 50 -foot Buffer area, the project proposes to install a fence along the 50 -foot Buffer, adjacent to the proposed walkway and patio. The fence will also serve as the safety fence for the pool. The portion of the fence along the southern side of the project will be a welded wire mesh fence to preserve the vistas to the south. Refer to Site Plan and Landscape Plan for additional details and notes. In conclusion, J.M. O'REILLY & ASSOCIATES, INC. believes the project can be approved with conditions and will not result in an impact on the BVW. We look forward to meeting with the Commission on April 23, 2024 to discuss the proposal. Please contact my office directly if you have any questions or need any additional information.

O'Reilly, P.E. J.M. O'Reilly & Associates, Inc. 1570 Main Street Brewster, MA 02360 Re: 2740 Main Street, Brewster, MA (Suzanne Corcoran) Mr. O'Reilly, This letter is an environmental assessment report concerning the above mentioned commercial property located at 2740 Main Street in Brewster. Independent Environmental Consultants, Inc. (IEC) conducted a site inspection and evaluation on 9-20-23, to delineate the existing wetland resource areas located behind the existing building within this property, towards the southeast. This inspection occurred during the summer season, and during the growing season. The property contains an existing commercial building (2740), with an asphalt, driveway, and an impervious parking area with parking spaces, and a wooden fence located behind the building. Existing topography drops in elevation from the area of the wooden fence, downgradient to the existing freshwater wetland (located off property). There are regulated wetland resource areas located off property and downgradient from the wooden fence located within the back of this property. The low- lying wetland contains areas with dense vegetation. The wetland area is located within an area of reduced topography, with high groundwater conditions, and a large freshwater pooling area. There is a BVW wetland (wooded swamp), some inland bank areas, and a large freshwater pooling area. IEC has delineated the boundary of the BVW wetland (wooded swamp) with the flags A2 —A7. The BVW wetland contains greater than 50% wetland vegetative species, hydric soils, saturated soils, high groundwater conditions, and a large pooling area. The low-lying wetland is located off property. There is a 50' buffer zone and a 100' buffer zone associated with the edge of wetlands. The 100' buffer zone extends towards Main Street, and the existing commercial building located at 2740 Main Street. The subject wetland resource areas continue off property. The freshwater pooling area may contain vernal pool habitat. The subject wetlands are classified as wetland resource areas under both the Town of Brewster Wetland Protection Regulations, and the state wetlands protection act. These wetlands and wetland buffer zones are under the jurisdiction of the Brewster Conservation Commission, and DEP SERO. Paul J.

T1 — Small Locust that has been damaged 1/2 way up the trunk which resulted in dieback to tops and decline in tree health. T2 — 18" Maple has co -dominant stem which is not ideal for tree health. Branch unions are also weak due to environmental issues. T3- 22" Locust has a slight lean towards the building. The Locust also has slight dieback within the canopy and weaker branch unions. This is not ideal for a tree near a building. T4- 12" Cherry has black knot throughout the crown with dense vine vegetation. The tree has a heavy lean. Black knot will decline the canopy overtime causing death of the tree. T5- 16" Cherry has black knot throughout the crown with dense vine vegetation. This cherry also has a strong lean towards the parking lot and deadwood throughout the canopy. Black knot will decline the canopy overtime causing death of the tree. T6- 10" Maple has uneven growth due to damage that occurred to stem. Weaker branch unions may result in decline and failure of the main stem. T7- 10" Locust has extreme root damage which will weaken the tree over time. Multiple co - dominant stems will result in failure to main stem. T8 — 16" Locust has been damaged, and the top was removed by storm winds. This causes decay and rot at the top of the stem. This tree will decline over time and will fail. All trees highlighted above are not ideal trees to have within landscape or property. All trees are recommended to be removed.

Stormwater Management Plan Overview Stormwater management controls are proposed for the portion of Project Site to address the additional roof and patio areas as proposed for the Spa expansion project. The existing paved parking area, as reconfigured with the addition, will continue to drain stormwater to the south into a riprap swale and underdrain outlet. The existing riprap swale and under drain were approved and installed when the existing building was originally constructed in 2007. The project proposes to address the additional hardscape areas (roof and patio) to conform to the Massachusetts Stormwater Requirements as a redevelopment project. The proposed post -development stormwater management plan consists of one (1) subsurface leaching facility which will be connected to the roof gutter and downspout system and channel drains within the patio. The proposed leaching facility is proposed within the paved parking area and is designed to meet the 25 year storm event and produces a reduction in the peak discharge rates for the 100 -year storm event (pre vs. post discharge). The project, as a redevelopment project, proposes to improve stormwater controls prior to the discharge to the south. Although strict conformance to the MA Stormwater Handbook is not required, the project does meet the requirements needed for a redevelopment. As such we offer the following summary of the MA Stormwater check list and O&M of the systems. As shown in the HydroCAD Modeling report, the proposed stormwater controls will reduce the site -wide peak discharge rate for the 2-, 10-, 25- and 100 -year storms. The site -wide post -development 100 -year storm peak discharge rate relative to pre -development conditions has decreased from 3.34 CFS to 2.88 CFS. The discharge rates for each of the three individual discharge points have also decreased relative to pre -development conditions, as shown in Table 1 below. Table 1: Peak Discharge Comparison Storm Event (year) Discharge Point Pre-Dev. (ft3/sec) Post-Dev. (ft3/sec) 2 0.90 0.73 10 1.71 1.44 25 2.32 1.97 100 3.34 2.88 Note: HydroCAD modeling includes time of concentration (Tc) and other factors in determining peak discharge rate. As such, the total site discharge rate may not equal the sum of the discharge rates for each discharge point. Pagel of SCANDINATIVE CAPE COD, LLC 2740 MAIN STREET, BREWSTER, MA STORMWATER MANAGEMENT REPORT AND O&M APRIL 4, 2024 1M0 -3831C For HydroCAD modeling analysis of the stormwater systems, the following methods and assumptions were used: • Simple Dynamic • Rawls Rate of 8.27 in/hr for sands within the subsoil layers for subsurface leaching galleys. • Rawls Rate of 2.41 in/hr for the loamy sands in the upper soil layers for dry water quality swales. The proposed stormwater controls also meet the minimum 80% Total Suspended Solids (TSS) removal requirements of the MA DEP Stormwater Manual, as shown in the attached TSS Removal Sheet. 2. Erosion Control Plan - Temporary Siltation Barrier & Silt Socks Prior to start of construction, the following steps shall be taken to address erosion: • The erosion controls shall include a row of staked 9 -inch straw wattles as shown on the Site Plan and adjacent to the edge of the clearing along the east side of the roadway. Refer to Plans for wattle locations and details. • A second row of straw wattles shall be installed along the edge of the parking area, adjacent to the existing riprap stone swale. The straw wattles shall remain in place to protect the stone swale during construction. • The erosion controls shall be monitored and corrected during the entire construction phase and until the site has been stabilized with ground cover and/or landscape mulch. • Contractor shall be required to provide extra siltation controls in case a repair is needed to the straw wattles. 3. Massachusetts Stormwater Management Design Standards The following is a description of how the proposed project meets the Massachusetts Stormwater Handbook design standards. Standard 1: No new untreated discharges: This standard is met since there are no new untreated stormwater discharges proposed. When the property was originally developed, the project proposed a stone rip -rap swale with an underdrain on the south side of the parking area. The existing swale is currently providing stormwater controls for the existing paved parking area. The project proposes to reduce the discharge from the underdrain with the reduction in paved areas associated with the existing swale. Standard 2: Maintain Pre -development peak discharge rate: This standard has been met. As shown in the HydroCAD Modeling report, the proposed stormwater controls will reduce the site -wide peak discharge rate for the 2-, 10-, 25- and 100 -year storms. See table 1 above. Standard 3: Groundwater Recharge: Page 2 of 8 SCANDINATIVE CAPE COD, LLCO 2740 MAIN STREET, BREWSTER, MA STORM WATER MANAGEMENT REPORT AND O&M APRIL 4, 2024 JMO-3831C This standard is met. The proposed stormwater management systems are sized so that the total recharge volume provided exceeds the minimum groundwater recharge volume specified in the handbook and the proposed stormwater recharge galleys will drawdown within 72 hours of a storm event. In accordance with the MA Stormwater Manual, the required recharge volume factor (F) required across the impervious area (A) is 0.6 inches per hour for hydraulic soil group A soils. Coarse Sand (Rawls Rate: 8.27 inches per hour) has been used in the sizing of the stormwater recharge galleys. Refer to the HydroCAD Stormwater Modeling Report in Appendix. The required recharge volume is calculated based on the total pavement and roof areas on site. • Required Recharge Volume R„= F x A = (0.6 in)(1 ft/12 in)(4,182 sf) = 210 cf (new roof and patio areas) • Recharge Storage Provided (Subsurface leaching facilities) = 757 cf > 210 cf • The drawdown for the subsurface leaching facilities for the roadway is 24 hours < 72 hour maximum allowance. Standard 4: Water Quality: This standard has been partially met. The stormwater system will remove 80% of the annual load of Total Suspended Solids (TSS) via subsurface leaching facilities, of the new roof and patio area. Standard 5: Land uses with higher potential pollutant loads: Not Applicable as this is a redevelopment Project. Standard 6: Stormwater discharges within Zone 11 or Interim Wellhead protection area of a public water supply and stormwater discharges near or to any critical area. Not Applicable as the project is not within a Zone 2 and is considered a redevelopment project. Standard 7: Redevelopment: This standard is met. The discharge rates are being reduced as part of the project. Reductions in all storm events are provided with the proposed leaching facility sized to address the 2, 10 and 25 year storm events. Standard 8: Construction Erosion Control Plan: The project is subject to the proposed Erosion Control Plan as described in this report. Straw wattles shall be implemented as required to mitigate soil erosion. Standard 9: Long Term Operation and Maintenance Plan: A long-term 0&M plan has been submitted as part of this report. The property owners will operate and maintain the stormwater systems. Standard 10: Illicit Discharges: This standard is met since there are no illicit discharges at this site and no illicit discharges proposed.

The soil testing completed for the sewage system design, encountered a dense silt loam (firm) over a layer of medium to coarse sand (C2 layers). Groundwater: Groundwater elevation was estimated to be at approximately EL = 10, as outlined in the Cape Cod Commission Groundwater Contour Map (GIS System). The soil testing did not encounter water down to a depth of 16 feet below grade (EI=16.8+/-). Zone 11: The parcel is not located within a Zone II Groundwater Recharge mapped area. Topography: The topography is sloping from the road down to the edge of a vegetated wetland. Site Conditions: The existing lot is vacant woodlands directly adjacent to Marshview Lane. Page 3 of 9 PAGOS-HALLER ASSESSORS' MAP 127, PARCEL 14 8 MARSHVIEW LANE, BREWSTER, MA STORMWATER MANAGEMENT REPORT JMO-9042 FEBRUARY 21, 2024 2. Stormwater Management Plan Overview Stormwater management controls are proposed for the portion of the property that is to be developed. The area of land to be developed is 42,320 SF+/- and is adjacent to a large, vegetated wetland resource on the southern portion of the parcel. The subject parcel also is subject to coastal storm flowage, (BFE=14). The area includes all land within the proposed limit of work up to the property boundary of Marshview Lane. The remaining portion of the property is outside of the limit of work and will remain natural. The proposed post -development stormwater management plan consists of three dry water quality swales to provide initial treatment of driveway runoff. The swales are then connected to two leaching facilities. The roof area is being served by two independent leaching pits which will be connected to the gutter and down spout system of the proposed dwelling. The Existing and Proposed Watershed Plans in Appendix A and Appendix B for delineations of the site's subcatchment areas. Due to the topography of the parcel and the location of the vegetated wetland as a receptor, all drainage facilities are sized on the 100 -year storm event, (8.5 inches per event). • Subcatchment 1 consists of the easterly portion of the property. The area includes the driveway/parking, walkway and a portion of the landscape area on the southeast side of the dwelling. Stormwater runoff associated with the driveway and walkway is directed to a small gutter inlet structure which then overflows into the dry water quality swale #1. The swale will be constructed using sand as a base then covered with 4 inches of loam, refer to the Plan. The swale will include an overflow inlet to the subsurface leaching facility. The swale is sized for the containment of the 1" rainfall event from the driveway area. • Subcatchment 2 consists of the remaining southern portion of the lawn area (running west to the LOW line) and the proposed circular driveway with walkway. The area includes two dry water quality swales and a subsurface leaching facility. Stormwater runoff associated with the driveway and walkway is directed to dry water quality swale #2, within the circular portion of the driveway. The swale will include an overflow inlet to the subsurface leaching facility. The swale is sized for the containment of the 1" rainfall event from the driveway area. o The remaining yard area is addressed with a shallow dry water quality swale, adjacent to the edge of the lawn and limit of work line. The swale is to be 6 inches deep and will act as a low point to the area for the collection of stormwater at the surface. The shallow swale will be equipped with an overflow inlet to the subsurface leaching facility. • Subcatchment 3 consists of the subsurface leaching facilities for the roof area. The roof area is being connected to the leaching drywells by a gutter and downspout system. Each of the drywelis will serve half of the roof area of the proposed dwelling. As shown in the HydroCAD Modeling report, the proposed stormwater controls will reduce the site -wide peak discharge rate for the 2-, 10-, 25- and 100 -year storms. The site -wide post -development 100 -year storm peak discharge rate relative to pre -development conditions has decreased from 0.70 CFS to 0.24 Page 4 of 9 PAGOS-HALLER ASSESSORS' MAP 127, PARCEL 14 8 MARSHVIEW LANE, BREWSTER, MA STORMWATER MANAGEMENT REPORT JMO-9042 FEBRUARY 21, 2024 CFS. The 0.24 CFS discharge rate is for the remaining portions of the parcel, including the rear portion of the dwelling (beyond the roof line). The discharge rates for each of the storm events have been outlined in Table 1, as shown below. Table 1: Peak Discharge Comparison Storm Event (year) Discharge Point — Vegetated Wetland Pre-Dev. (ft3/sec) Post-Dev. (ft3/sec) 2 0 0 10 0.02 0 25 0.14 0.02 100 0.70 0.24 Note: HydroCAD modeling includes time of concentration (Tc) and other factors in determining peak discharge rate. For HydroCAD modeling analysis of the stormwater systems, the following methods and assumptions were used: • Simple Dynamic • Rawls Rate of 8.27 in/hr for sands within the subsoil layers for subsurface leaching galleys. • Rawls Rate of 2.41 in/hr for the loamy sands in the upper soil layers for dry water quality swales. The proposed stormwater controls for the driveway and walkway areas also meet the minimum 90% Total Suspended Solids (TSS) removal requirements of the Town of Brewster Stormwater Management Bylaw, as shown in Appendix C: TSS Removal Sheets. Page 5 of 9 PAGOS-HALLER ASSESSORS' MAP 127, PARCEL 14 8 MARSHVIEW LANE, BREWSTER, MA STORMWATER MANAGEMENT REPORT JMO-9042 FEBRUARY 21, 2024 3. Erosion Control Plan - Temporary Siltation Barrier & Silt Socks Prior to start of construction, the following steps shall be taken to address erosion: • Contractor shall coordinate the driveway access curb cut with the Brewster Department of Public Works. • The erosion controls shall include a row of staked 9 -inch straw wattles backup by a silt fence surrounding the down gradient areas to be disturbed (limit of work). Erosion controls shall be installed around all areas of disturbance. Refer to Plans for wattle locations and details. • Once the driveway stormwater systems are installed, a row of staked 9 -inch straw wattles shall be set surrounding each of the swales, to prevent silt and debris from clogging and/or damaging the dry water quality swales and subsurface leaching facilities. • The erosion controls shall be monitored and corrected during the entire construction phase and until the site has been stabilized with ground cover and/or landscape mulch. • Contractor shall be required to provide extra siltation controls in case a repair is needed to the straw wattles. The Stormwater Operations and Maintenance Plan is included as a separate document in order to address the long-term maintenance of the stormwater systems.

Massachusetts Stormwater Management Design Standards The following is a description of how the proposed project meets the Massachusetts Stormwater Handbook design standards. Standard 1: No new untreated discharges: This standard is met since there are no new untreated stormwater discharges proposed. See Standards 4- 6 calculations. Standard 2: Maintain Pre -development peak discharge rate: This standard has been met. As shown in the HydroCAD Modeling report, the proposed stormwater controls will reduce the site -wide peak discharge rate for the 2-, 10-, 25- and 100 -year storms. The site - wide post -development 100 -year storm peak discharge rate relative to pre -development conditions has decreased from 0.70 CFS to 0.13 CFS. The discharge rates for each of the three individual discharge points have also decreased relative to pre -development conditions, as shown on Table 1 in the Stormwater Management Plan Overview section. Standard 3: Groundwater Recharge: This standard is met. The proposed stormwater management systems are sized so that the total recharge volume provided exceeds the minimum groundwater recharge volume specified in the handbook and the proposed stormwater recharge galleys will drawdown within 72 hours of a storm event. In accordance with the MA Stormwater Manual, the required recharge volume factor (F) required across the impervious area (A) is 0.6 inches per hour for hydraulic soil group A soils. Coarse Sand (Rawls Rate: 8.27 inches per hour) has been used in the sizing of the stormwater recharge galleys. Refer to the HydroCAD Stormwater Modeling Report in Appendix. The required recharge volume is calculated based on the total pavement and roof areas on site. Dry Water Quality Swale #1: • Required Recharge Volume R„ = F x A = (0.6 in)(1 ft/12 in)(1,985 sf) = 99 cf (driveway and walkway) • Recharge Storage Provided (Swale Capacity) = 247 cf > 99 cf • The drawdown for the subsurface leaching facilities for the driveway/patio and roof runoff is 24 hours < 72 hour maximum allowance. Dry Water Quality Swale #2: • Required Recharge Volume R„ = F x A = (0.6 in)(1 ft/12 in)(1,158 sf) = 58 cf (driveway and walkway) • Recharge Storage Provided (Swale Capacity) = 229 cf > 58 cf • The drawdown for the subsurface leaching facilities for the driveway/patio and roof runoff is 24 hours < 72 hour maximum allowance. Roof Runoff: • Required Recharge Volume R„ = F x A = (0.6 in)(1 ft/12 in)(2,560 sf) = 128 cf (roof area only) • Recharge Storage Provided (Swale Capacity) = 532 cf > 128 cf Page 7 of 9 PAGOS-HALLER ASSESSORS' MAP 127, PARCEL 14 8 MARSHVIEW LANE, BREWSTER, MA STORMWATER MANAGEMENT REPORT JMO-9042 FEBRUARY 21, 2024 • The drawdown for the subsurface leaching facilities for the driveway/patio and roof runoff is 24 hours < 72 hour maximum allowance. Standard 4: Water Quality: This standard has been met. The roof runoff stormwater system will remove 80% of the annual load of Total Suspended Solids (TSS) via subsurface leaching facilities. Driveway area stormwater controls will remove 94% of TSS with the dry water quality swales followed by leaching facilities. TSS removal calculation tables for roadway and roof runoff are included in the Appendix. In accordance with the MA Stormwater Manual, the required water quality depth (Dwq) across the impervious area (A) is 1.0 inches per hour in areas containing soils with rapid infiltration rate greater than 2.4 in/hr. The required water quality volume is based on the total pavement area on site. Dry Water Quality Swale #1: • Required Water Quality Volume VWg=DWgxA= (1.0 in)(1 ft/12 in)(1,985 sf)=165 cf (driveway & walkway) • Water Quality Storage Provided = 247 cf > 165 cf Dry Water Quality Swale #2: • Required Water Quality Volume V,.,g = Dwq x A = (1.0 in)(1 ft/12 in)(1,158 sf) = 96.5 cf (driveway and walkway) • Water Quality Storage Provided = 229 cf > 96.5 cf Standard 5: Land uses with higher potential pollutant loads: This standard has been met. The proposed use is a single-family residence. Standard 6: Stormwater discharges within Zone 11 or Interim Wellhead protection area of a public water supply and stormwater discharges near or to any critical area. This standard has been met. Not applicable as the site is not within a Zone 2 contributory area, however the 1 inch Required Water Quality Volume for discharges within an area with a rapid percolation rate (>2.4 in/hr) has been met, see Standard 4 calculations. Standard 7: Redevelopment: This standard is not applicable, the project is a new development. Standard 8: Construction Erosion Control Plan: The project is subject to the proposed Erosion Control Plan as described in this report. Straw wattles and erosion control blankets shall be implemented as required to mitigate soil erosion. Standard 9: Long Term Operation and Maintenance Plan: A long-term O&M plan has been submitted with this report, refer to Stormwater Operation and Maintenance Manual. The property owner will operate and maintain the stormwater systems. Standard 10: Illicit Discharges: This standard is met since there are no illicit discharges at this site and no illicit discharges proposed.

The Stormwater Report must include: • The Stormwater Checklist completed and stamped by a Registered Professional Engineer (see page 2) that certifies that the Stormwater Report contains all required submittals.1 This Checklist is to be used as the cover for the completed Stormwater Report. • Applicant/Project Name • Project Address • Name of Firm and Registered Professional Engineer that prepared the Report • Long -Term Pollution Prevention Plan required by Standards 4-6 • Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan required by Standard 82 • Operation and Maintenance Plan required by Standard 9 In addition to all plans and supporting information, the Stormwater Report must include a brief narrative describing stormwater management practices, including environmentally sensitive site design and LID techniques, along with a diagram depicting runoff through the proposed BMP treatment train. Plans are required to show existing and proposed conditions, identify all wetland resource areas, NRCS soil types, critical areas, Land Uses with Higher Potential Pollutant Loads (LUHPPL), and any areas on the site where infiltration rate is greater than 2.4 inches per hour. The Plans shall identify the drainage areas for both existing and proposed conditions at a scale that enables verification of supporting calculations. As noted in the Checklist, the Stormwater Management Report shall document compliance with each of the Stormwater Management Standards as provided in the Massachusetts Stormwater Handbook. The soils evaluation and calculations shall be done using the methodologies set forth in Volume 3 of the Massachusetts Stormwater Handbook. To ensure that the Stormwater Report is complete, applicants are required to fill in the Stormwater Report Checklist by checking the box to indicate that the specified information has been included in the Stormwater Report. If any of the information specified in the checklist has not been submitted, the applicant must provide an explanation. The completed Stormwater Report Checklist and Certification must be submitted with the Stormwater Report. ' The Stormwater Report may also include the Illicit Discharge Compliance Statement required by Standard 10. If not included in the Stormwater Report, the Illicit Discharge Compliance Statement must be submitted prior to the discharge of stormwater runoff to the post -construction best management practices. 2 For some complex projects, it may not be possible to include the Construction Period Erosion and Sedimentation Control Plan in the Stormwater Report. In that event, the issuing authority has the discretion to issue an Order of Conditions that approves the project and includes a condition requiring the proponent to submit the Construction Period Erosion and Sedimentation Control Plan before commencing any land disturbance activity on the site.

Stormwater Checklist and Certification The following checklist is intended to serve as a guide for applicants as to the elements that ordinarily need to be addressed in a complete Stormwater Report. The checklist is also intended to provide conservation commissions and other reviewing authorities with a summary of the components necessary for a comprehensive Stormwater Report that addresses the ten Stormwater Standards. Note: Because stormwater requirements vary from project to project, it is possible that a complete Stormwater Report may not include information on some of the subjects specified in the Checklist. If it is determined that a specific item does not apply to the project under review, please note that the item is not applicable (N.A.) and provide the reasons for that determination. A complete checklist must include the Certification set forth below signed by the Registered Professional Engineer who prepared the Stormwater Report. Registered Professional Engineer's Certification have reviewed the Stormwater Report, including the soil evaluation, computations, Long-term Pollution Prevention Plan, the Construction Period Erosion and Sedimentation Control Plan (if included), the Long- term Post -Construction Operation and Maintenance Plan, the Illicit Discharge Compliance Statement (if included) and the plans showing the stormwater management system, and have determined that they have been prepared in accordance with the requirements of the Stormwater Management Standards as further elaborated by the Massachusetts Stormwater Handbook. I have also determined that the information presented in the Stormwater Checklist is accurate and that the information presented in the Stormwater Report accurately reflects conditions at the site as of the date of this permit application.

Revisions are proposed to the Wetlands Protection Act (WPA) regulations (310 CMR 10.00) and the Water Quality Certification (WQC) regulations (314 CMR 9.00). Components of the regulation package are requirements of the 2018 State Hazard Mitigation and Climate Adaptation Plan. MassDEP engaged in robust stakeholder and technical expert consultation processes in developing the regulations. MassDEP is developing a user- friendly guide and trainings for Conservation Commissions to help implement the new regulations once they become final and take effect. Why is MassDEP Proposing to Update its Regulations? The proposed regulation revisions have two main objectives: • Promote coastal resiliency against worsening impacts of storms, flooding, and sea level rise through ■ First-time standards to protect the coastal floodplain (Land Subject to Coastal Storm Flowage or "LSCSF") from damage, which will help to maintain its natural capacity to protect structures and properties from storm damage and sea level rise ■ Provisions to support resilient shorelines, roadways, and water dependent uses and to allow scientific test projects to study effects of climate change • Promote resiliency against increasing flooding, storm damage, and runoff pollution through updated stormwater management standards that ■ Incorporate current science and data for better rainfall estimates into updated stormwater management rules and replace outdated (60 -year -old) precipitation data ■ Improve consistency between state regulations and EPA stormwater permit ■ Encourage using nature in design ("environmental design") through seven cost-effective green design credits in lieu of built structures New Coastal Floodplain Standards The proposed new performance standards for development in the coastal floodplain (or LSCSF) will reduce damage to property, infrastructure, and the natural shoreline associated with sea level rise and coastal storms. • In areas closest to the ocean where waves are 3 ft or more (the "Velocity Zone"), prohibit most new development and allow reconstruction on open pilings. Some water dependent uses (e.g., boatyards, work in a Designated Port Area related to water -dependent industrial uses) and minor work in the velocity zone would be permitted. This will prevent new construction in areas where storm damage is greatest and worsening. The majority of the Velocity Zone (approximately 90%) will not be affected by these new regulations since those areas are either already developed or overlap with other regulated wetlands resource areas (e.g., beach or dune). • In areas where waves are equal to or greater than 1.5 ft but less than 3 ft (Moderate Wave Action zone ["MoWA"]), allow new and redevelopment provided structures are built on open pilings. • Allowable activities in the Velocity and MoWA Zones include plantings, pedestrian walkways, boat launching facilities and open boat storage, docks, piers, and compliant septic systems. 1 • In areas where waves are less than 1.5 ft (Minimum Wave Action zone ["MiWA"]), permit new and redevelopment and other activities provided that projects use best available measures to minimize adverse effects and that structures are elevated on pilings or solid foundation. • Allow redevelopment as long as projects improve existing conditions so as to improve degraded floodplain areas, which are particularly at risk. • As a component of a flood control program, allow berms or height increases of existing seawalls where necessary to protect more highly developed urban areas. Additional Resilience Provisions • Allow road elevation (and associated widening of the road base in the wetland), and relocation of roads and water -dependent facilities (e.g., boatyards), for those threatened by sea level rise and coastal storms. • Encourage nature -based shoreline protection such as "living shorelines" that provide flood control and storm damage prevention for properties threatened by sea level rise and coastal storms. • Allow scientific test projects to gather information on the ability of wetland resource areas to respond to the effects of climate change. • Streamline stormwater permitting for shared use paths on abandoned rail beds to support the state goal of reducing vehicle miles travelled to reduce greenhouse gas emissions. Updated Stormwater Standards for Flood Protection and Water Quality Improvements The updated stormwater design standards will improve resiliency against increasing flooding, storm damage, and runoff pollution. • Replace outdated (60 -year -old) precipitation data with up-to-date data (from the "NOAA 14 Atlas"). Storms have been increasing in intensity with climate change so today's "100 -year storm" delivers more water than the 100 -year storm of the 1960s. Using the older data to design stormwater systems results in pipes that are not large enough to carry the water. The water that is not captured in the systems can cause flooding, scouring of riverbanks, damage to buildings and bridges, and other problems. Using the up-to-date precipitation data to design stormwater systems will help to prevent stormwater from one property from causing damage to neighboring properties. • Ensure resilience of wetlands resources and stormwater systems by requiring that systems are designed to handle extreme precipitation events. Rather than using the mid -point or "average" precipitation presented by NOAA Atlas 14, MassDEP is proposing to require that precipitation amounts be 90% of the upper end of the range of historical precipitation. This is called "NOAA 14 PLUS" and is proposed to ensure that stormwater from most (80%) storms will be adequately managed. This somewhat increased precipitation is based on actual events. • Reduce flooding, reduce pollution, and replenish groundwater and streamflow by requiring that stormwater systems be designed to move more stormwater into the ground. • Incentivize the use of nature and ecological processes to handle stormwater runoff and to prevent flooding and polluting nearby waters. This will reduce the amount of pavement and pipes and will be less costly for developers. • Better align with the Environmental Protection Agency's requirements for stormwater management (through its General Permit for Stormwater Discharges from Small Municipal Separate Storm Sewer Systems in MA) to protect Massachusetts waters from harmful stormwater pollutants. Frequently Asked Questions 1. What stakeholders did DEP consult in developing these proposed regulations? • Stormwater Advisory Committee 2 ■ Convened February 2020, held six sessions concluding June 2021 • Members included MassDOT, MA DCR, MACZM, EOEEA, MA Fish & Game, U.S. EPA, Homebuilders and Remodelers Association, NAIOP, Mass. Association of Conservation Commissions, Pioneer Valley Planning Commission, Central Massachusetts Regional Stormwater Coalition, Mass. Municipal Association, Mass. Audubon, Mass. Rivers Alliance, Boston Society of Civil Engineers, Association of MA Wetland Scientists, and other subject matter experts • 18 additional presentations and 6 additional meetings with a variety of entities in 2021-22 including EBC, MACC, MSMCP, NEIWPCC, Homebuilders, NAIOP, MassDOT, Resilient Mystic Collaborative, MA Rivers Alliance, and others. • LSCSF Technical Advisory Group • Convened / met in 2014, 2018, re -convened in 2021 to review draft regulations • Membership included MACZM, EOEEA, MACC, NAIOP, Homebuilders and Remodelers Assoc., Mass. Audubon, Association of MA Wetland Scientist, and other subject matter experts 2. How do the proposed LSCSF standards compare with the building code? • DEP regulation focuses on wetlands resource protection; building code focuses on protecting building/structures. DEP, with EEA and DCR, has been working with Board of Building Regulations and Standards (BBRS) to promote consistency between the proposed standards and the forthcoming 10th edition of the state building code. • BBRS is considering adopting similar provisions; MassDEP anticipates increased consistency once 10th edition is released. MassDEP expects the V Zone standards will be stricter for new development. 3. How much of the Massachusetts coast will be affected by the proposed prohibition on new development in the V Zone? • Only —10% of the V Zone (not submerged) has the potential to be affected. Some of these areas are on lots with existing development or are existing open space or subject to regular tidal flooding. • Over 90% of the V Zone either overlaps other regulated wetland resource areas, like beach or dune (82%), or is already developed (8%) and is unlikely to be affected. 4. How will the proposed regulations affect housing development? • The proposed stormwater standards may result in larger stormwater control measures for new development to control peak runoff and bring MA up to date with current rainfall and extreme events data. Redevelopment will only need to meet the standard to the extent possible. • Some redevelopment will need to meet new standards for pollutant removal, which may result in larger stormwater controls. • Potential cost increase of site development can be offset using proposed green design credits. 5. What is Green Site Design? • Green site design (also called "Environmentally Sensitive Site Design" or ESSD") uses natural solutions - like trees and buffer zones - to manage stormwater instead of detention basins and other traditional infrastructure • MassDEP proposes seven green site design credits • Substantially reduces cost, minimal or no maintenance 6. How is DEP proposing to use current data to update rainfall projections? • MassDEP proposes to replace outdated (60 -year -old) rainfall data with current data (from "NOAA Atlas 14"). Storms have been increasing in intensity with climate change. Using older data for design results 3 in pipes not large enough to carry stormwater, which causes flooding, and damage to buildings, bridges, and other infrastructure. • Rather than using average rainfall from NOAA Atlas 14, MassDEP proposes to use 90% of the upper end of the range of historical precipitation from actual storm events. This is called "NOAA 14 PLUS" and will ensure that stormwater from most (80%) storms will be adequately managed. 7. How will proposed changes to stormwater pollutant removal affect development? • MassDEP proposes to align with EPA MS4 stormwater rules that apply to over 260 communities. • New development proposal to remove 90% Total Suspended Solids (TSS) and 60% Total Phosphorus (P) • Redevelopment proposal to remove 80% TSS and 50% P. ■ Exceptions, developed with stakeholder input, include single family houses, most subdivisions or multi -family developments less than ten lots/units, roadway maintenance, boatyards, and shared use paths. ■ Improved pollutant removal will decrease pollution in nearby wetlands/waterbodies and help meet the Clean Water Act. 8. Why is DEP requiring more stormwater runoff to be put into the ground? • To better address rain events which cause flooding. • MA is experiencing more drought and more intense rainfall. These rainfall events result in more runoff, flooding, storm damage, and pollution into our waters. Recharging rainfall into the ground will remove pollutants and replenish groundwater supplies and rivers. 4 1 DRAFT letter to be sent by MSMCP to MassDEP on or before April 30th Feel free to use any of the comments below to: (1) craft your own tailored letter to MassDEP or (2) simply note your endorsement of the comments provided in MSMCP's letter. Please note: the MSMCP board may make minor modifications to this letter and will be submitting this closer to the April 30th deadline. *Due to the length and number of comments provided, we have Bolded the specific "ask" for each section. April 30, 2024 Via Email: dep.wetlands@mass.gov RE: Wetlands -401 Resilience Comments MSMCP's Comments on MassDEP'S Resilience 1.0 Draft Regulations and 2.0 Recommendations Dear MassDEP: Introduction and Appreciation MSMCP is a body of municipal conservation professionals representing over 100 member municipalities and reaching hundreds of individual professionals. Our mission is to support one another through a robust offering of educational and networking events. MSMCP members focus on implementation and permitting under the Wetland Protection Act (WPA) Regulations (the Regulations). Our comments are from the perspective of those who daily engage with consultants, residents, and municipal officials and the Regulations and permit processes in efforts to protect and enhance remarkably diverse wetland ecosystems in these challenging times of climate change. Our board alone has over 150 combined years of experience implementing these regulations across the Commonwealth. MSMCP has been working closely with MACC, Mass Audubon, Mass Rivers Alliance, AMWS, and other technical experts to review, assess, and comment on the proposed Resilience 1.0 Draft Regulations. While MSMCP has been focused on general and inland wetland regulations, our partners have focused on the proposed changes to Chapter 91, Section 401, the Stormwater Handbook, Coastal Resources, and Restoration. We have greatly appreciated the collaborative approach and endorse the comments that these other organizations are submitting independently to MassDEP, provided here as addenda [forthcoming]. 2 This letter focuses on the general and inland wetland regulations. It provides MSMCP's suggested modifications of the proposed "1.0" changes and our suggestions for the forthcoming "2.0" reg change package. Throughout the letter, underlining indicates topics and bold -face indicates specific requests. We sincerely appreciate the effort that MassDEP put into creating these draft regulation changes and commend MassDEP for focusing on ways to make Massachusetts and its wetland resources more resilient to climate change. We see many of the proposed changes to the general and inland wetland regulations as valuable steps towards increased public safety and ecological health in the face of climate change. All the proposed changes to the general and inland wetland regulations on which we (and our colleagues) have not commented, we endorse and encourage you to promulgate swiftly. Overarching Concerns We feel that some of the proposed changes will be very challenging to implement and/or could lead to unintended detrimental consequences and so should be refined prior to promulgation. Many of our detailed comments can be summarized under four overarching concerns. • The revised regulations must strike a reasonable balance between scientific precision and overly burdensome requirements that render them too difficult for a majority of volunteer conservation commissions and applicants to implement. In other words, they must be readily practicable. • In the face of climate change and invasive species, the revised regulations must acknowledge and reflect the difference between "alterations" resulting from new development and "alterations" resulting from ecological restoration. Ecological restoration projects should be considered projects that support "public health and safety", as mosquito control projects are. • Regulation revisions must strive to create greater consistency of thresholds, exemptions/allowances, and requirements based on existing wetland functions and values and the potential impacts (or benefits) on those wetland functions and values of proposed projects, not on the user groups conducting the activity. • MassDEP should immediately engage stakeholders in the "Resilience 2.0" planning process. Regulatory changes should be borne of early and close coordination with conservation commissions, conservation staff, and professional non-profit staff, the 3 people responsible for day-to-day interpretation and consistent implementation of these regulations. Recommendations for the Proposed "1.0" Inland Regulations As a large group of daily implementers of the wetland regulations, MSMCP urges MassDEP to give careful consideration to our detailed comments (and those of our colleagues), reach out with questions or for assistance, and make the necessary changes prior to promulgation. 310 CMR 10.02(2)(b) Minor Exemptions • 10.02(2)(b)(2)(r). We agree that maintenance of shared use paths should be allowed without the need for permitting, so this new minor activity is appropriate, but it has too many details about means and methods and creates too narrow a management opportunity. We suggest the following revisions: o 10.02(2)(b)r.iv. The draft language is too detailed. The language as proposed creates implementation challenges since the means and methods are site - specific. We are concerned that the allowance of cutting shrubs and branches, and chipping and spreading this material in place may result in the unintended localized spread of invasive species. We recognize that the proposed language mirrors existing language in 10.02(2)(b)(2)n. (vegetation cutting for road safety maintenance). We recommend deleting the language under 10.02(2)(b)4.iv. between "To prevent the possible export (...) disposed" and creating a guidance document or policy instead. We recommend that this type of specificity be removed from existing language under 10.02(2)(b)(2)n for similar reasons. o 10.02(2)(b)r.v. We question why the language incorporates the provision that "(...) no work on any component of a Stormwater Management System is performed, including but not limited to drainage swales" occurs under this minor activity provision. This is contradictory to activities that are already exempt as maintenance of stormwater systems. We are in favor of the new minor activity but request that the following proposed language be deleted: "(...) no work on any component of a Stormwater Management System is performed, including but not limited to drainage swales." • 10.02(2)(b)n.iv. We recognize that MassDEP's proposed language immediately above comes from this passage (10.02(2)(b)n.iv. Vegetation cutting for road safety 4 maintenance), however, as noted above, we believe that the allowance for cutting and chipping in place of vegetation could lead to unintended consequences of spreading invasive species. We urge MassDEP to revise this language through guidance on best management practices rather than keeping these details in the regulations. 310 CMR 10.04 Definitions • Highway Specific Considerations. This gives one agency (MassDOT) special rights. Municipal DPWs often have control of roadways of similar size and undertake projects of similar scales, and so should be afforded similar allowances. The regulations should not be based on the governing agency, but should be based on the size of the roadway, the scale of the proposed project, the intended public benefits, and the potential environmental impacts. • Impervious surface. Since solar arrays are often sited in fields and other entirely pervious areas, there should be opportunities for applicants to utilize site -specific information on pre- and post -construction land cover and infiltration capacities to determine the need for stormwater management systems. • Maintenance of an Existing Public Roadway. This definition should not include all instances of "replacing existing drainage pipes". Since some drainage pipes are deep beneath the paved surface, replacement might require extensive excavation, large spoil piles, and dewatering. • Maintenance of an Existing Public Roadway. This new term adds confusion because of language in 10.02(2)(b)(2) and 10.53(3)(f). • Public Shared Use Paths. The new definition in 10.04 states that the Path must be on "public property or on private property pursuant to an easement that provides for public access". MassDEP should afford all owners of publicly accessible land with Public Shared Use Paths the same allowances and requirements under the regulations. This could include land trust and other permanently protected public or private property with public access. • The proposed definition of Zone A references 310 CMR 22 (Drinking Water), but the text does not match. The draft wetland regs use the term "surface water" where Drinking Water (22.00) uses the term "surface water source", which is defined therein as a public water supply. Surface water is not defined as a public water supply. • Many New Terms or Definitions have been introduced and incorporated throughout the redline version (e.g., the multiple new definitions introduced in 10.36(2)). All terms 5 should have an entry in 10.04 with either a standalone definition or a reference to the section where the term is defined and used. Examples of new terms include: o Limit of Moderate Wave Action (LiMWA) o Scientific Research Projects 310 CMR 10.05 Procedures • 10.05(4)(a) Notices of Intent. The regulations should not require such a high level of stormwater management detail for every NOI filing. We recommend two possible alternatives. o Strike the new sentence "A construction period .... Activities" and replace with "All projects must address erosion, sedimentation control, and pollution prevention with plans appropriate to and commensurate with the proposed alterations, even those projects otherwise exempt from the stormwater standards." OR o Strike the new sentence "A construction period .... Activities" and change the text in the general instructions for NOIs. o Please note there is a typo: "... operation and maintenance plan, and an illicit discharge compliance statement." • 10.05(6)(m)(6): Requiring unpaved footpaths in natural areas to comply with the Stormwater Management Standards seems unreasonable. Trails generally rely on country drainage and so do not "fit" the intentions of the Standards. We ask MassDEP to include unpaved footpaths in natural areas as exempt activity under the Stormwater Management Standards 10.05(6)(1). • 10.05(6)(m)(7): This new provision now requires that Maintenance of an Existing Public Roadway comply with the Stormwater Standards to the maximum extent practicable, however, 10.02(2)(b)(2)(p) appears to exempt the same roadway maintenance from review. 310 CMR 10.12 Notice of Intent for an Ecological Restoration Project • (2) The numbering underlined below needs to be fixed because the original (2) was stricken. "Notwithstanding the provisions of 310 CMR 10.54(4)(a)5., 10.56(4)(a)4., and 10.60, a person submitting a Notice of Intent for an Ecological Restoration Project that meets the requirements of 310 CMR 10.12(1) and (2) is exempt ..." 6 310 CMR 10.13 Eligibility Criteria for Restoration Order of Conditions • f We suggest using the word "evidence" in place of the word "demonstration". "If the project will involve the dredging of 100 cubic yards of sediment or more or dredging of any amount in an Outstanding Resource Water, the Notice of Intent includes a demonstration that an application ..." 310 CMR 10.53 and 10.24 Limited Project Provisions • 10.53(u)8. & 10.24 (7)(c)(8) Public Shared Use Paths o Delete the statement that a separate NOI may be filed either concurrently to the filing of the NOI for the project, or after the OOC is issued, for vegetation management and other activities as defined in 310 CMR 10.02(2)(b)2.r.i.-v. in wetland Resource Areas. Applicants are always welcome to file NOIs. o Delete "abandoned railbed" in first line. "Public Shared Use Path" is already defined in 10.04. MassDEP should consider more broadly defining a Public Shared Use Path in this limited project provision. Municipal or land trust paths should be afforded the same limited project status. • 10.53(4)(e)5. Typo: The letter "r" is missing from the word "through" in "...set forth in 310 CMR 10.53(4)(a) though (d)..." Additional Miscellaneous Suggestions • Include a list of common acronyms, particularly for new definitions. This could be incorporated in Section 10.04. • Provide frequent outreach and education about the new regulations once promulgated. Dissemination of detailed and multi -faceted explanations of these new regulations and the purposes and intents behind them for the Conservation Commissions and conservation professionals who will implement them will be essential. MSMCP welcomes the opportunity to assist MassDEP in these efforts. • Provide headers at the top of every page of the new regulations with the complete section and subsection reference to facilitate navigation through the numerous lengthy sections that comprise many pages. • Make sure the new version of the regulations is formatted with headers so that the pdf will have internal hyperlinks allowing users to "jump" to specific sections. 7 2. Coordinate on the Development of Regulatory Reform Package 2.0 As we all know, these draft regulation changes alone will not achieve our goal of true resilience. We appreciate that MassDEP has said that it is already working on regulatory reform package "2.0." MSMCP has identified a number of issues that should be addressed in the next regulatory reform package. Many of these suggested revisions are straightforward. Some of these suggestions warrant additional discussion. We implement the wetland regulations on a daily basis and know what works well and what is challenging. We have a lot to offer to help make 2.0 a real success. We urge MassDEP to begin a robust process of stakeholder engagement with consultants, field professionals, and conservation agents so that we may help you develop practical, strong, climate resilient regulations. Here we provide some suggestions to begin the conversation. 310 CMR 10.02(2)(a) Activities Within the Areas Subject to Protection ... • Trail Maintenance. We ask MassDEP to create a new section to exempt Maintenance of Existing Trails in use by the public. This could be done by adding a new section "10.02(2)(a)3. Maintenance activities on trails that traverse Areas Subject to Protection under M.G.L. c. 131, § 40" which reads: "Activities conducted to maintain, repair or replace, but not substantially change or enlarge an existing public trail, provided said work utilizes the best practical measures to avoid or minimize impacts to wetland resource areas outside the footprint of said trail". Boardwalks, puncheons, waterbars, and other basic trail infrastructure need to be routinely maintained or replaced. Land managers should be able to conduct this essential maintenance work to protect wetland resource areas without having to secure a permit. 310 CMR 10.02(2)(b) Minor Exemptions • 10.02(2)(b)(a) Unpaved pedestrian walkways. We ask Mass MassDEP to define Conservation Property to include all these types of natural land onto which the public is invited. Currently, unpaved pedestrian walkways (trails) less than 3 feet wide for public access on "Conservation Property" are exempt from the regulations. However, many trails traverse general municipal land, land trust properties, and private property with conservation restrictions affording public access. Additionally, we urge MassDEP to consider increasing the 3 -foot width to 4 feet because the state's own guidance on accessible trails encourages trails are "at least 36" wide, and usually wider" (emphasis added). • 10.02(2)(b)(e) Conversion of lawn to uses accessory to residential structures such as decks, sheds, patios, pools. We ask MassDEP to remove inground swimming pools from this minor activity. Construction of inground swimming pools involve significant 8 excavation, large impervious areas around the pool, fencing, and often involves discharge of chlorinated water. Having no Conservation Commission oversight of these projects has often led to after -the -fact permitting due to erosion or other problems which have impacted wetland resource areas. Tree cutting and grading has occurred in concert with some pool projects when landowners misunderstood these activities were not part of the minor activity provision. As an exempt activity, there is no requirement for an O&M plan to ensure that chlorinated water is not discharged to wetland resources areas without first being dechlorinated. Requiring a wetland permit and preconstruction review of all inground pool projects in the buffer zone and Riverfront Area will result in better oversight and reduce the non-compliance we see problematic with exempting some inground pools from wetland permitting. • 10.02(2)(b)(n) Vegetation cutting for road safety maintenance. o We ask MassDEP to update the AASHTO 2011 Policy to "7th edition, 2018 or most current". o 10.02(2)(b)(n)(iv), We ask MassDEP to remove the detailed language: "To prevent the possible export .... Chipping, disposal method and spreading chips..." This language is too detailed (means and methods are site -specific and creates some implementation challenges). We suggest working with a stakeholder group and creating a guidance document on appropriate vegetation cutting BMPs that could be applicable to this and other minor activities that involve vegetation cutting. • Cutting of certain high -risk trees. We ask MassDEP to add a new minor activity: allowing landowners to remove up to 5 unsafe trees over 6 inches that are in the buffer zone or riverfront area and are threatening structures or human safety. Trees are suffering from the effects of climate change. Invasive pests like wooly adelgid and emerald ash borer are decimating many of our native hemlocks and ashes. Increases in the number and severity of storms have resulted in more damaged trees. We recognize that certain parameters need to be codified and suggest a guidance document could be created to define and address thresholds associated with minor land management activities and requirements for Conservation Commission notification for certain activities (e.g., giving the Commision 30 days to comment but not necessarily require a permit, akin to forest cutting plans). • Removal of invasive vegetation. We ask MassDEP to add a new minor activity to 310 CMR 10.02(2)(b)(2) which reads: "Removal of turf lawn and/or non-native invasive herbs, vines, and shrubs, provided: (1) the activity is located more than 50 feet from 9 the mean annual high water line within Riverfront Area or from BVW, whichever is farther and (2) provided erosion and sedimentation controls are implemented until the area is stabilized with 75% coverage of native species". Invasive plants are one of the biggest threats to our native habitats. Quick and effective management of invasives is essential in controlling the spread of invasive plants. 310 CMR 10.03(6)(b), 10.04 (Alter), 10.05(3)(2)(b), and 10.58(6) Application of Herbicides and Cutting in Rail Rights -of -Way • Regulation of herbicides and cutting in railway rights -of -way. We ask that MassDEP clarify the requirements for permitting the use of herbicides and cutting to control vegetation in rail rights -of -way in Buffer Zones and Riverfront Area. MBTA and Keolis routinely claim exemptions that do not seem to exist and many cases are now in litigation. 310 CMR 10.04 Definitions • "Activity" and "Alter". We ask MassDEP to consider clarifying that "vegetation" used in the definitions of "Activity" and "Alter" applies only to NATIVE vegetation. See the explanation below. • Definitions for "Vernal Pool" and "Vernal Pool Habitat". We ask MassDEP to create new definitions for "Vernal Pool" and "Vernal Pool Habitat". Currently, Vernal pool habitat includes the definition of both the depression and the 100' jurisdictional area. We also ask that MassDEP extend the jurisdiction to provide a 100 -foot Buffer Zone to vernal pools, regardless of whether it falls within a resource area. Suggested changes: o "Vernal Pool" is a basin or depression that typically holds water for at least two continuous months through the spring and is free of adult, reproducing fish populations. Vernal pools are essential breeding habitat for a variety of amphibian species such as Wood Frog (Lithobates sylvaticus) and the Spotted Salamander (Ambystoma maculatum) and provide other extremely important wildlife habitat functions during the non -breeding season for these species. Vernal pools are important habitat for other wildlife species. The boundary of a vernal pool is the maximum water level in such a basin or depression and is identified by direct observation or by field indicators of the maximum extent of flooding. o "Vernal Pool Habitat" is the area between the boundary of a vernal pool and the boundary of a jurisdictional resource area that contains the vernal pool, or 100 feet from the edge of the vernal pool boundary, whichever distance is greater. 10 310 CMR 10.05: Procedures • We ask MassDEP to add the following sentence in 10.05(8) "If requesting an ORAD Extension, the Applicant must submit written confirmation by a professional with relevant expertise that the resource area delineations remain accurate". This language appears in 10.05(6)(d) however most Commissions and conservation professionals are unaware of this language since it appears in the wrong section in the regulations (it's placed in the Order of Conditions section and not the Extensions section). • We ask MassDEP to clarify which projects are subject to stormwater management. Currently, any activity other than the 4 listed categories appear to be subject to stormwater management regulations, however, small projects (e.g., restoration, foot paths) appear to require stormwater management. • 10.05(8) We ask MassDEP to: (1) move mention of rules associated with extensions from 10.05(6)(d) to 10.05(8); and (2) within 10.05(8) to allow 5 -year extensions for any appropriate project (i.e., "where special circumstances warrant and where those special circumstances are set forth in the Order.") 310 CMR 10.06: Emergencies • We ask MassDEP to add new text 10.06(6): "An Emergency Certification issued by a conservation commission shall be signed by a majority of the commission. It may also be signed by a single member or agent of the commission, if said Certification is ratified by a majority of members at the next scheduled meeting of the Commission", similar to language provided for Enforcement Orders. 310 CMR 10.24 Limited Projects • 10.24(1)(b). The nature -based resiliency requirement is non -binding. Having applicants merely "consider" these measures does not mean they will implement them. MassDEP should consider stricter requirements for these measures. • 10.24(7)(c). Limited Projects in Coastal Areas at Risk from Sea Level Rise. Allowing the relocation of roads and railroads to avoid the impacts of sea level rise could result in damage to other ecosystems. We ask MassDEP to postpone this proposed modification until completion of the Resilient Coasts plan. 11 310 CMR 10.53 Limited Projects • We ask MassDEP to expand the Limited Project provisions to simplify permitting requirements for routine land management projects necessary to address the impacts of climate change. o We ask MassDEP to expand the Limited Project provisions to facilitate large scale invasive species work in wetland resource areas with specific regulatory review standards. Some invasive species removal projects extend into wetlands and cover >5,000 s.f. There should be a simplified way of allowing landowners and other organizations to tackle invasive species removal projects without triggering complicated permitting processes. o We ask MassDEP to add a limited project provision which specifically allows small- and medium -scale invasive species removal projects with specific regulatory review standards. Non-native invasive plants pose a major threat to the health and survival of our native ecosystems, and are on the rise with climate change. Currently, invasive plant control work requires time-consuming, costly, and complex wetland permitting devised for construction projects. Quick identification and removal of invasive plants minimizes the dramatic negative effects of these plants and allows for the recovery of native species diversity and native wildlife habitat, a recognized wetland value. o We ask MassDEP to expand the limited project provision in 10.53(j)(a) to allow: "The construction of new public footpaths and associated boardwalks/ puncheons that are constructed close to the ground provided, however, that such structures are constructed on pilings, sills, or posts so as to permit the reasonably unobstructed flowage of water." Boardwalks and other basic trail infrastructure that cannot avoid wet environments serve to protect the wetland resource areas and their functions and values. Because most boardwalks and puncheons are only elevated 4-12" above the ground for safety reasons, shading is inevitable, and because many boardwalks and puncheons are built on sills, loss of vegetation under the sills is inevitable. Therefore, under the current regulations, all boardwalk and puncheon construction in BVW requires wetland replication. Our proposed minor modification (above) would allow Conservation Commissions to approve public boardwalks and puncheons as Limited Projects. This would reduce the need for inland wetland replication which generally results in the destruction of forested buffer zones in protected public open spaces. Larger public boardwalk/puncheon projects could still be required to undertake wetland replication based on the size, scope, and nature of the project and the 12 opportunity for less impactful alternatives. Below in this letter are recommendations for a Guidance Document of Best Trail Management Practices (BTMPs) to ensure the health of wetland resource areas. 310 CMR 10.55 Bordering Vegetated Wetland Performance Standards • 10.55(2). We ask that MassDEP modify the definition of BVW and how the boundary of a BVW is defined, to reflect the 2022 "Massachusetts Handbook for Delineation of Bordering Vegetated Wetlands" that was released in March 2023. • 10.55(4)(c). We ask that MassDEP simplify the permitting process for trail construction projects by adding to the Bordering Vegetated Wetland regulations a new section in 10.55(4)(c)(4) allowing Commissions to permit new trails in wetlands when: "said work involves the creation of a public trail for non -motorized use (i.e., hiking, skiing, mountain biking, etc.) which will alter less than 500 s.f. of BVW, provided alternatives that attempted to avoid and minimize impacts were considered and that the trail will permit the reasonably unobstructed flowage of water." Wetland trail construction should be subject to review under the WPA, but that review should be simplified. Narrow unpaved pedestrian walkways in publicly accessible open space often traverse wetlands. When wetland trails are properly constructed, they preserve wetland functions and values and help build a culture of appreciation and stewardship for these vital resources. (Note: Allowance for ADA compliance and motorized mobility devices must be considered.) 310 CMR 10.57 Land Subject To Flooding (Bordering and Isolated Areas) • 10.57(2)(a)5. Vernal Pool Habitat should not necessarily need to be certified by DFW in order to be afforded protection. We ask that MassDEP consider allowing field -based evidence submitted to the Conservation Commission by competent professionals as acceptable proof of vernal pool habitat. • 10.57(2)(a)6. Vernal pools. We ask that MassDEP revise the language to read: "The boundary of a certified or uncertified vernal pool shall be based on field observations of the maximum extent of flooding and delineated by a competent source meeting the criteria in 310 CMR 10.60(1)(b). Vernal pool habitat shall include the area within 100 feet of the boundary of the vernal pool itself." DFW does not certify the boundary of vernal pools, so we suggest removing those references. The application would be submitted with the applicant's representative delineating the vernal pool boundary and the Conservation Commission or MassDEP, as the issuing authority, verifying that delineation. Conservation Commissions and MassDEP staff may meet the requirements 13 under 10.60 but they may not; simply listing the reference to 10.60 would be adequate here. • 10.57(2)(a)3. We ask MassDEP to change references from the software -based BLSF calculations to "listed in the National Oceanic and Atmospheric Administration (NOAA) Atlas 14 Volume 10 (version 3.0 or later version are permissible)" and any such references to using NOAA 14 throughout the proposed Wetland Protection Act Regulatory changes and Stormwater Handbook to "listed in the most recent "National Oceanic and Atmospheric Administration (NOAA) Atlas". No changes have been proposed to the ILSF section, but ISLF calculations currently refer to BLSF. Changes to 10.57(2)(a)(3)a-c change to require a more comprehensive software to be used in the BLSF calculations, and reference NOAA Atlas 14. Using the most recent rainfall data available through NOAA promotes climate resilience and avoids the necessity to update the Regulations in the future. NOAA 15 is already in development. 10.57(2)(b) Isolated Land Subject to flooding • We ask MassDEP to consider expanding the jurisdiction over small isolated wetlands by reducing the size of ILSF to account for loss of isolated wetland protections as a result of the Sackett Decision. • We ask that MassDEP consider adding vernal pools as its own dedicated wetland resource area, with a 100 -foot Buffer Zone. Vernal pools truly are a vital wetland resource subject to flooding, as identified in the Act: "No person shall remove, fill, dredge or alter any bank, riverfront area, fresh water wetland, coastal wetland, beach, dune, flat, marsh, meadow or swamp bordering on the ocean or on any estuary, creek, river, stream, pond, or lake, or any land under said waters or any land subject to tidal action, coastal storm flowage, or flooding, other than in the course of maintaining..." (emphasis added). 310 CMR 10.58: Riverfront Area Regulation Revisions • Many Conservation Commissions and Conservation Agents find it difficult to interpret many sections of the Riverfront Area sections. We are grateful for the hard work of the working groups who helped develop the regulations which were promulgated in 1996, however, after almost 30 years of implementing these regulations, we have discovered a number of challenges. We welcome discussions with MassDEP as the areas of concern are too complex to detail here. We ask that MassDEP work with MSMCP and MACC to address the following areas of concern. 14 o Defining Mean Annual High Water o Interpreting "practical and economically equivalent" o Interpreting the Redevelopment requirements for mitigation/restoration for "non-compliance" of more than one performance standard o Clarifying the distinction, if any, between 310 CMR 10.58(5)(c) and (d) o Requiring an Alternatives Analysis for Redevelopment projects o How the regulations apply to large sites with small amounts of pre-existing development WPA Forms Since MassDEP has recently requested MACC and MSMCP to provide comments on the WPA application and permit forms, following we share just a few of our most pressing requests. We ask that MassDEP work closely with MSMCP and MACC to update the application and permit forms. • General Comments. o Application forms should mirror permit forms. o Application forms and permit forms should reflect the regulations. o Forms should list the date, project, site, and owner/applicant information on the first page. o Forms should rely on "appendices" for site or project specific information (such as coastal resource areas, rare species, and stormwater). o There should be forms that are tailored for purely inland municipalities. o The language of the forms should be made intelligible to laypeople. o Wetland Fees do not cover the administrative costs for processing, reviewing, issuing, and mailing wetland permits. We ask MassDEP to increase application fees. • Comments regarding the NOI form. o The NOI should be greatly simplified and shortened. o Much of the NOI is not relevant to a majority of projects; the use of appendices would greatly simplify the application for many applicants. o The NOI form (under C.7.) should add categories of projects to which the stormwater standards do not apply (i.e., not "industrial, commercial, institutional, office, residential and transportation projects"). o The NOI form should reflect the regulations and ask the applicant to confirm they have met the relevant performance standards. For example, although applicants are required to check off whether a project qualifies as 15 redevelopment in Riverfront Area, this doesn't require confirmation how the applicant has met the standards for 310 CMR 10.58(5). • Comments regarding the OOC form. o The OOC should be modifiable, to allow for routine additions such as longer lists of approved plans, the Commission's findings, and the Commission's site - specific conditions. o The OOC should be more succinct and tailored so that the information is pertinent and homeowners and contractors will read it. o The OOC should not ask for data that is not supplied by the applicant, e.g., the closest distance from work to wetlands. o Clarification should be given for whether the "work" in the "closest distance from work to wetlands" includes restoration work which may happen 0 feet from the wetlands edge or the closest new construction which may be 25 or 50 feet away. o The OOC Riverfront Area fields should be simplified and clarified to ensure consistency of information. For example, how commissions define and fill out areas of alteration and replication fields is highly inconsistent. (How does one "replace" riverfront area?) • Comments regarding the Determination of Applicability form. o Conservation Commissions need to have more latitude to issue negative determinations of applicability or general permits for small-scale or low -impact projects (such as the hand -pulling of aquatic invasives). The full-scale NOI/OOC permitting process is an enormous disincentive to ecological restoration and management. After all, it is the invasive plants that are creating the alteration and violating the Act, not the efforts to remove them. ;-) • Comments regarding the ORAD (Form 4B) o The ORAD form should be revised to correct an inconsistency. The Recording Block on Page 1 and the Recording Information on Page 7 should be removed. MassDEP Circuit Riders have confirmed that ORADs do not need to be recorded, yet Form 4B (last revised 4/22/2020) indicated that said Form must be recorded. ORADs are simply confirming a wetland boundary for 3 years; no work is associated with ORADs. When applicants record this document, it creates a cloud on a title. Although a landowner can Request a Certificate of Compliance (Form 8A) - that form does not include language appropriate for closing out an ORAD. 16 o The ORAD form should be revised to reiterate an important regulatory requirement. DEP should add a regulatory note on ORADs which states "If requesting an Extension, the Applicant must submit written confirmation by a professional with relevant expertise that the resource area delineations remain accurate, per 310 CMR 10.05(6)(d)." Most Commissions and conservation professionals are unaware of this language since it is difficult to find in the regulations. Develop Guidance Documents Conservation commissions and conservation staff would benefit from guidance documents which provide more detail about various regulatory provisions. • Herbicides and cutting in rail rights -of -way. We ask DEP to issue a guidance document outlining not only the exemptions afforded to railroads but permitting requirements and the recommended material to be submitted to each commission should railroads wish to conduct other activities which are not exempt. That way, Commissions can properly review the request and fully understand what is being asked of them. It does not appear that railroads are a qualifying structure which meets the exemptions of 310 CMR 10.02(2)(a)(2) or 310 CMR 10.03(6). In addition, mechanical removal is not included in 310 CMR 10.05(3)(2)(b); this only applies to herbicide removal. o MBTA and Keolis have claimed exemptions which don't exist (i.e. MBTA claims to be exempt from filing a Notice of Intent for mechanical vegetation removal). o In 2020, Keolis, on behalf of MBTA, filed RDAs in 99 communities for the review of the wetlands maps in each community as part of the renewal of the 5 -year Vegetative Management Plan (VMP). In the "work description" Keolis stated that "This work includes both chemical and mechanical controls as represented within the VMP available for viewing at fdcerailroadvegetation.com". In the submission, Keolis suggested the Commission consider issuing a Negative #2 determination (indicating the work is within an area subject to protection but will not remove, fill, dredge, or alter that area...) or issue a Number Negative 5 determination, citing as exemption 310 CMR 10.02(2)(a)(2). Twenty-two Commissions disagreed with Keolis' interpretation of the Regulations and denied the mechanical work under the RDA. MassDEP issued an SDA concurring with those decisions, which MBTA/Keolis appealed and the case is now in adjudicatory hearing with OADR. Unless mechanical cutting is an exempt activity expressly given to railroads, it seems prudent that Railroads be required to 17 submit detailed plans when they wish to cut vegetation or trees within Resource Areas and Buffer Zones. • Land management activities. We Ask MassDEP to Issue Guidance Documents clarifying and simplifying wetland permitting on essential land management activities. Best Management Practices surrounding high -risk tree removal, trail maintenance and construction, and invasive species management are well documented. Finding ways which allow landowners to manage their open space while ensuring best practices are adhered to is critical. MSMCP and other organizations welcome future discussions with MassDEP on devising guidance documents which simplifies the wetland permitting process and helps landowners conduct more climate resilience land management activities. For example, a guidance document regarding habitat restoration could set regulatory review standards based on the scope, scale, and size of restoration projects. • Puncheons and Boardwalks. As an alternative to our recommendation to allow boardwalks and puncheons on publicly accessible trails to be permitted as Limited Projects (as described on page 11), we Ask MassDEP to Issue a Guidance Document clarifying thresholds of negligible impact of boardwalks and/or puncheons on BVW functions and values as a result of shade and loss. MassDEP has required replication for small publicly accessible puncheons (because of shading and wetland loss) and elevated boardwalks (because of helical piers). A Guidance Document identifying Best trail management practices (BTMPs) to create and maintain stable trail surfaces and limit improper widening of the footbed and trampling of vegetation by hikers seeking to avoid wet areas should be promoted. Such BTMPs are evermore important as climate change intensifies storms and worsens flooding. Miscellaneous Our membership has suggested the following additional miscellaneous changes. • Update the 401 Water Quality Certification regulations regarding Outstanding Resources Waters (ORWs). We ask that MassDEP make practical allowances for minor incursions into ORWs for small projects that are responding to climate change and restoration needs. Currently, there is no provision in the Surface Water Regulations that allows even a negligible amount of fill to be introduced into an ORW. Even building a small boardwalk or puncheon on a walking path is considered 'fill' and requires filing for a major Water Quality Certification. Obviously, work in ORWs must be carefully regulated, however, prohibiting even a single puncheon on a wetland trail within an ORW is unreasonable. 18 • 10.05(3)(a)(1). To use consistent, defined terms, we ask that MassDEP change the language to read: "Any person who desires a determination as to whether M.G.L. c. 131, § 40 applies to land or to work that may alter an Area Subject to Protection under M.G.L. c. 131, § 40, may submit to the conservation commission a Request for a Determination of Applicability, Form 1." • 10.05(3)(a)(2). Currently, an RDA or NOI is required for any activity in the buffer zone. We encourage MassDEP to provide some discretion for local conservation commissions to utilize an administrative approval process for activities in the buffer zone which will not impact wetland functions and values. We feel strongly that individuals who wish to undertake minor activities (such as the removal of a high -risk tree) should be able to receive local approval from their local Conservation Commission without filing for a state permit. • Amending an OOC. We ask that MassDEP include a specific provision in the regulations that clarifies how an Order of Conditions can be amended. MassDEP should consider allowing Amended Orders that include minimal increases in resource area impacts, instead of requiring a new NOI to be filed. We also ask that MassDEP clarify whether an amendment to an Ecological Restoration OOC needs to be re -advertised in the Environmental Monitor.

However, as written on page 2-43, this inspection would be performed either by the ConComm or MassDEP. Understanding the design and signs of failure in SCMs is a technical skill that requires experience and training.

X Eilish Corey coreye@holliston.k12.ma.us Holliston Stormwater Dirt Roads Definitions Implication new regulations have on the "improvement" of dirt roads in Western MA - GIVEN The definition of compacted gravel will make dirt roads "impervious" and therefor any "improvements" to the roads will be subject to the 80% TSS and 50% TP requirements. This, along with the setbacks and requirements specifically for Cold Water Fisheries resources (100 -foot setbacks & cooling water to 68 degrees) are going to pose significant challenges for western mass communities to comply and additionally fund. Probably 80% of the dirt roads in western mass cross a CFR at least one - and its often where the most problems are. The exemption for "unpaved" does not include roads. The major problem facing dirt roads is washouts/erosion/mud/dust — which is all TSS — and taking into account how one would successfully use LID/GI, have a 100 -ft setback and lower the water temperature to 68 degrees prior to any discharges to a CFR is basically impossible. x x Angela Panaccione apanaccione@pvpc.org PVPC definitions "Near" 10.04 very vague, leaves to "Commissions discression".

Stormwater Precip Update- NOAA - 14+ May want to make a note of the new EEA Climate change projections dashboard (which is part of Climate resilient Mass; this allows you to see town specific precipitation projections using NOAA 14+ Stormwater Standard #2 Peak Rate Attenuation Table 2-7 (Pg 2-50) Several smaller SCMs including dry wells, tree box filters, and water quality swales are noted in Table 2-7 as "Does not have the ability to partially or fully meet the specific Standard". However, all of these SCMs can be designed to provide a measure of detention, particularly on smaller sites. For example, a subdivision may have single family houses with individual dry wells and are tributary to larger treatment SCMs. Although the dry wells would only provide detention during smaller rain events, they can decrease the overall size of the downstream SCM, saving on cost and size demands. Stormwater Standard #3 Stormwater Recharge recharge .8 vs. 1.0 inches Stormwater Standard #3 Stormwater Recharge Table 2-1 Rules for Groundwater Recharge (Page 2-11) Table 2-1 states that recharge volumes may be infiltrated to the maximum extent practicable for various conditions, including "been classified as contaminated". What are the specifications for this requirement? For instance, many soils by the roadsides become "contaminated" by virtue of their location or there are many swaths of areas that fall under the "Urban Fill" or "Udorthents" mapped by the NRCS. Stormwater Standard #6 Critical Areas Table 2-4b In Tables 2-4b through 2-4d, the language reads "only use proprietary manufactured separatores for pretreatment". This wording is potentially confusing, implying that only proprietary separators can be used for preatreatment, excluding other froms like deep sump catch basins, vegetated filters, etc. The language in Table 2-4a, "Proprietary manufactured separators may be used only for pretreatment" presents the requirement in a clearer fashion. Stormwater Standard #11 Total Maximum Daily Loads Table 2-6 (page 2-47) Table 2-6 lists the suitability of SCMs to treat TMDL pollutants, and several SCMs including bioretention area (filtration), extended dry detention basins, sand/organic filters, wet basins, and green roofs are noted as "unlikely to provide significant reduction of target pollutant". However, these technologies are listed in Appendix F, Attachment 3 of the MS4 permit as approved structural controls for meeting nutrient load reductions. This is a confusing contradiction between the two regulatory documents that will add to the administration and design burden when considering the selection of appropriate SCMs, particularly in retrofit scenarios. 1.0 Comments - WPA Regulatory changes Regs 1.0 Package.

This standard could potentially be onerous to design around, particularly for public entities with large drainage systems located in the public way with a variety of groundwater conditions. For instance, it would be a barrier to the installation of deep sump catch basins, which are much deeper than a typical catch basin but provide a measure of water quality. It could also have the side affect of driving up design costs; test pits to identify groundwater are not a typical component in the design of a typical pipe and catch basin system. For larger systems over a wide area and a myriad of conditions, the implication is that many soil investigations, including potentially at each individual drainage structure, would need to be performed.

Needs to be better discrepency between these acronyms as they seem to all mean just about the same thing - why can't the handbook pick one main acronym and run with it?

The LSCSF performance standards would then seem to apply to these inland sections of tidally influenced river within areas mapped for 1% flood risk in the 100 -year stomr (FEMA flood zones A, V, A99, AE, AO, AH, VE, & AR). However, in the table of contents/organization of the regs, LSCSF is listed as a coastal resource area even though it would seemingly apply to non- coasatal areas. This will lead to confusion of applicants, conultants, and commissions when permitting in these areas and attempting to properly apply the regs and meet performance standards. MA DEP should more clearely define where the LSCSF resource area is and clarify that this resource area can be present in certain areas of non -coastal / non CZM mapped portions of rivers which are tidally influenced. MA DEP could also consider calling out specific sections of river and indicating whether LSCSF applies, for example "the Merrimack River upstream to the Lawrence Dam" could clearly be defined within the regs if this is the area that MA DEP intends that LSCSF regs would apply to.

The ER definition should be expanded to facilitate more dam removals. x Alison Field-Juma afieldjuma@oars3rivers.org OARS Invasives Ecological Restoration projects Cons Coms need to have more clear latiitude to do negative determinations of applicability or general permits to manage aquatic invasives. Access for equipment over banks (e.g., for weed harvesters) should still have oversight, but handpulling in particular should not have to go through the permitting process which currently is a huge disincentive to ecological restoration and management. After all, it is the invasive plants that are creating the alteration and violating the Act, not the efforts to remove them... ;-) Native restoration planting Planting 10.36 (6)(a) Any stipulation in an OOC regarding installation of native plant species should include a requirment to protect the plantings against damage from herbivory by deer in particular. diatom@nenetworks.com Leverett Minor Activities pools 310CMR10.02(2)(b)(2) inground pools still exempt if over 50' from BVW X John Keeley jkeeley@burlington.org Invasive Plants Chipping 10.02(2)(b)(n)(iv) Chipping cut invasive plant material and spreading chips may not prevent spread if fruits/berries are present on the stems.

Michele Grzenda grzendam@lincolntown.org Agreed! I think hand removal and if there was an approved means and methods list of removal, both should be minor activities subject to adminsitrative approval Victoria, planning@freetownma.gov // Also agreed. I've has several applicants look to remove invasives on their property and end up backing out because of the cost of filing and meeting regulations when in Riverfront Area. Becca, bsolomon@ashlandmass.com Revising the minor activity section on "accessory to SFH" to EXCLUDE inground pools 10.02 (2)(b)(2)(e) impacts can and do occur when large inground pools are constructed in the buffer. they should not be exempted simply because they are on lawn and are 50 -feet away from the wetland edge Expand definition of "Conservation Parcels" in the minor activity provision for footpaths. 10.02 (2)(b)(2)(a) Currently only Conservation Parcels are afforded this minor activvity provision, however, many trails extend across general municipal land, Land Trust properties, etc. Consider expanding this provvision to those landowners.

Many of these projects have impacts that need review. Related to this, "minor projects" with conditions are very hard for con comms to deal with. Either things should be exempt or not, rather than saying "only if there are erosion controls, only if work is minimized, etc." because the conditions still require Commission/staff involvement in reviewing the project which the public doesn't see as consistent with "exempt." Kathy Sferra conservation@stow- ma.gov I agree with this which is why we adopted local pool regulations that don't allow new pools in 0-60' buffer zones and sets strict conditions for new pool construction through the 100' BZ We also define pools and pool decks as impervious surfaces. We also charge a local Category 2 fee for new pools. Karen Strauss karenstrauss@comcast.net (Eastham) streamline review and approval of pedestrian woodland trails in wetlands 10.53(J)(a) Consider expanding the limited project provision in 10.53(J)(a) to state: "The construction and maintenance of footpaths and associated boardwalks and puncheons which utilize rustic timber or lumber boardwalk that is built close to the ground (< 24 inches above ground) provided, however, that such structures are constructed on pilings, joists, sills, or posts so as to permit the reasonably unobstructed flowage of water. Michele Grzenda grzendam@Iincolntown.org the current limited project under 10.53(J) also requires that the activity allows adequate light to maintain vegetation (this requirement to "maintain adequate light to maintain vegetation is counter to a safe treadway because of the height it imposes. It is also impractical for very simple and rustic pathway infrastructure that enables trail users to safely cross small ephemeral watercourses or wet, boggy areas) Provide fact sheets on best practices Leave the details to a library of fact sheets Shared Use Path Take out certain language that addresses methods and means and maintenance of drainage swales (NOI before 2008 and OOC after 1983) MBTA feels they can cut vegetation under their ROW maintenance exemption that allows for herbicide Add explicit language that says "cutting of vegetation requires an NOI".

There's a lot of confluence of native / non-native and invasive / non- invasive. There's also push back on some of these terms for not being inclusive which could be examined before being implemented as well. Becca, bsolomon@ashlandmass.com allow general permits for DPW, Inv. Spp management, and trail work There are numerious maintanance type activities with Conservation Commissions, Land Trusts, and DPW wish or need to take on in their daily operations; consider some type of allowance for general permits Michele Grzenda grzendam@lincolntown.org Agreed. Becca, bsolomon@ashlandmass.com streamline review and approval of pedestrian woodland trails in wetlands 10:55(4)(c)(4): add a new section in 10:55(4)(c)(4): Said work involves the creation of woodland trails for non -motorized use (i.e. hiking, skiing, mountain biking, etc.) which will alter less than 500 s.f. and will permit the reasonably unobstructed flowage of water. Michele Grzenda grzendam@lincolntown.org since woodland trails can enhance user experience, educate users about the values of wetlands, and help build a culture of appreciation and stewardship for these vital resources — we want to encourage the construction and simplified permitting of these trail systems.

Is there a way to require conservation commission notification (similar to forest cutting plans) - where the con com has 30 days to comment but not necessarily require a permit? some hazzard trees are in wetland resource areas; is there a way to expand a minor activity to include wetlands? Michele Grzenda grzendam@lincolntown.org Agreed! I think administrative apparoval should be able to approve tree removal in the buffer zone with a letter from an arborist or tree removal company deeming it unsafe. Victoria, planning@freetownma.gov ACEC salt marsh fill prohibition difficult permitting for restoration Heidi Ricci hricci@massaudubon.org create a clear process by which con coms can review and approve invasive spp work in Wetland resource areas some inv. spp. removal projects extend well into wetlands and often cover an area >5,000 s.f.

Cpmmnnweahh of Massaph:setts EOEA Tempe of Use Report a map error AR Application -Additional Info Erin Hilley, owner 54 Tubman Road April 3, 2024 I would like to remove six Norway maples (Acer platanoides) from along the east side of my driveway. Two are saplings, between 2-3 inches DBH. The largest one is 10-12 inches DBH and the remaining three are between 5 and 7 inches. These trees are within the buffer zone to a vegetated wetland. The shrub swamp wetland is in decent condition vegetatively (winterberry, black tupelo, willow) but the wetland buffer is mostly invasive plants (Norway maple, shrub honeysuckle, English ivy, Asiatic bittersweet, multiflora rose, English oak). In my experience, Norway maples help to perpetuate the invasives or at least greatly hinder establishment of native plants and a native plant community. They are also fast-growing, relatively short-lived trees that fall apart when large and therefore not great for the side of my driveway. I'd like to remove them sooner than later. Black tupelo (Nyssa sylvatica) is somewhat common on my property and in this case, there are sapling tupelos close to the Norway maples that will thrive once the Norway maples are removed. I have seen this in another part of my property. I am asking approval to remove the six Norway maples however, ultimately, the cost will also factor into what I can remove at this time. Four Norway maples, two saplings and two in the 5- 7" DBH range, growing near the tupelo saplings are my current priority for removal. I hope to get permission from Conservation and remove them asap, prior to full leaf out. 54 Tubman Road driveway with the house in the background. Trees in question are growing on the left side of the driveway. This photo shows my driveway and two of the Norway maples that I would like to remove. They are the two noticeable trees on the left side of the driveway. See the next two photos showing each of them. Norway maple 1 and 2 from above photo.
