We are looking at having a Halloween trail somewhere on the property, ideally on the area in purple on the included map. This would be a scary trail for people to go on similar to a haunted house. If this is a problem, we can abandon this component of the event, but we figured we should bring it up for discussion.

The 441,662 s.f. vacant property is located in an area of seasonal and year-round homes and has a Bordering Vegetated Wetland on the northeast section of the property and an Isolated Vegetated Wetland on the southeast section of the property. A backhoe tracked through the IVW buffer to access the eventual soil testing area in May of this year. No work took place within Priority/Estimated Habitat of endangered species. Isolated Vegetated Wetland The Isolated Vegetated Wetland was flagged by Independent Environmental Consultants, Inc. and located by Down Cape Engineering. No adverse effects resulted from the work as no major trees were taken down and recent pictures show vegetation growing within the vehicle tracks. The area is relatively stable, and no future erosion is expected. The IVW will continue to act fully in its capacity to provide habitat and food sources for wildlife. Any future work within the buffer will take place after proper Conservation Approval.

The subject property is adjacent to the existing residential house at the Holmes property off of Crowells Bog Road. The property borders existing residential houses located along Winstead Road (paved road) in Brewster, which is located to the west of 0 Crowells Bog Road. The property is located near Long Pond and Sheep Pond in Brewster. Independent Environmental Consultants, Inc. (IEC) conducted a site inspection and evaluation of the subject property on 6-13-23 and 6-27-23, to delineate the boundary of wetland resource areas located within this forested site. This site inspection occurred during the spring season, growing season, and during leaf -out conditions. Sections of the property may be classified as Estimated Habitat and/or Priority Habitat of Endangered & Rare Species by NHESP. The subject property contains a well established vegetative community — overstory, understory, and herbaceous layers. There is a mixture of deciduous and conifer vegetation within this site. The topography rises and falls within this vegetative site. There is an existing track path made by an excavation machine within this property in the past. This existing track area leads to an area of past excavated soils located within this forested site. Topography drops in elevation from Winstead Road area downgradient to Crowells Bog Road. There are a number of existing topographic depression areas located within this property. Transects were conducted within the property to review the low topographic areas and topographic depressions located within this wooded site. A bordering vegetated wetland is located within the northeastern section of the property. This BVW wetland (wooded swamp) is located within a topographical depression. This low-lying wetland is located at the toe of slope of a significant embankment area. This wetland contains a large seasonal pooling area. The wetland contains greater than 50% wetland vegetation, hydric soils, saturated soils, very high groundwater conditions, and a seasonal freshwater pooling area. Vegetation is dense within the wetland and surrounding area. IEC has delineated the edge of wetlands with the flags B1— B15. There is a 50' buffer zone and a 100' buffer zone associated with the edge of wetlands. This BVW wetland continues off property within low-lying areas. This BVW wetland is a state regulated wetland resource area and a town regulated wetland resource area. An isolated wetland feature, isolated vegetated wetland (ivw) & isolated land subject to flooding (ilsf), exists within one of the topographic depressions within this site. This isolated wetland feature is located close to the previously mentioned track path located within this site. The isolated wetland contains greater than 50% wetland vegetation, hydric soils, high groundwater conditions, and a seasonal pooling area. Vegetation is dense within this wetland area. This vegetated wetland feature is located within the lowest area of the topographical depression. IEC has delineated the boundary of wetlands with the flags Al — A8. There is a 50' buffer zone and a 100' buffer zone associated with the delineated edge of wetlands. This isolated vegetated wetland is a town regulated wetland (Brewster Conservation Commission). This small isolated vegetated wetland is not classified as a state regulated wetland (DEP). Paul J.

I am in conversafion with a potenfial client at 432 Blueberry pond rd who would like to push back some encroaching vegetafion on exisfing paths to Blueberry Pond Associafion Beach and another path to the edge of the pond. Both paths are currently in use, albeit nominally, due to the extent that vegetafion, ie briar, low hanging branches and poison ivy impedes access. All that is needed is to hand prune and run a gravely or trimmer down the path to allow for intended use to resource areas. Everything is stable there is no erosion and outlined maintenance would not affect any of the ecological funcfions negafively, and assume an AR would be adequate. Aftached area few photos. I’m happy to meet onsite should you like to walk the property.

Property Description Lot Area: 81,995 SF+/- Parcel Improvements: The site is to be developed with a single-family dwelling and driveway. Wetlands: The parcel contains two vegetated wetlands, with a third vegetated wetland across Vesper Pond Drive. Soils: The NRCS Soil Survey places the parcel within the soil unit 263B Soil, Carver- Hinesburg loamy coarse sand, 3 to 8 percent. Medium to coarse sands were found in the ‘C1’ layer of all preliminary test holes conducted on the site. Groundwater: Groundwater elevation was determined to be at approximately EL=20, based on test hole information and the water surface elevation within the wetlands during the early Spring high groundwater season. Zone II: The parcel is not located within a Zone II Groundwater Recharge mapped area. Topography: The topography is rolling with a high point at the back of the lot. Site Conditions: The existing lot is vacant woodlands directly adjacent to Route 6A and Vesper Pond Drive. Page 4 of 9 EASTWARD COMPANIES - 9218 STORMWATER MANAGEMENT REPORT ASSESSORS’ MAP 138, PARCEL 74, ROUTE 6A, BREWSTER, MA SEPTEMBER 8, 2023 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 23,000 SF+/- and is adjacent to Vesper Pond Drive, in between the site’s two wetland areas. The area includes all land within the proposed limit of work, including some land within the Vesper Pond Drive road layout for the proposed driveway. 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, which also provide stormwater leaching for the roof runoff. See the Existing and Proposed Watershed Plans in Appendix A and Appendix B for delineations of the site’s subcatchment areas. • Subcatchment 1 consists of the southerly portion of the circular driveway/parking and surrounding areas. Stormwater runoff associated with the driveway is directed to dry water quality swale #1. There is a perforated pipe at the bottom of the stone layer of the swale which flows to drainage leaching facility #1. • Subcatchment 2 consists of the northerly portion of the circular driveway/parking and surrounding areas. Stormwater runoff associated with the driveway is directed to dry water quality swale #2. There is a perforated pipe at the bottom of the stone layer of the swale which flows to drainage leaching facility #2. • Subcatchment 3 consists of the entrance driveway and surrounding areas. Stormwater runoff associated with the driveway is directed to dry water quality swale #3. There is no piping required for dry water quality swale #3, as the swale is sufficiently sized to allow effective stormwater control without an additional leaching facility. • Subcatchment 4 consists of the rear patio and surrounding areas. Stormwater runoff associated with the patio is directed to 4” wide trench drains along the edge of patio. Trench drains are connected to each other and outlet into drainage facility #1. • Subcatchments 5 and 6 cover the front and rear sides of the garage, dwelling and porch roof area. Stormwater runoff from the roof is controlled by gutters and downspouts, with the front half of the building’s runoff piped to drainage facility #2 and the rear half piped to drainage facility #1. • Subcatchments 7, 8 and 9 consist of the lawn and landscaped areas for each of the 3 existing discharge points that are not connected to the stormwater systems. These areas will be vegetated and do not include any hardscapes. 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 0.92 CFS to 0.62 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.

As such, the total site discharge rate may not equal the sum of the discharge rates for each discharge point. 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 90% Total Suspended Solids (TSS) removal requirements of the Town of Brewster Stormwater Management Bylaw, as shown in Appendix C: TSS Removal Sheets.

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 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. Page 7 of 9 EASTWARD COMPANIES - 9218 STORMWATER MANAGEMENT REPORT ASSESSORS’ MAP 138, PARCEL 74, ROUTE 6A, BREWSTER, MA SEPTEMBER 8, 2023 4. 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 0.92 CFS to 0.62 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. • Required Recharge Volume Rv = F x A = (0.6 in)(1 ft/12 in)(8,013 sf) = 401 cf (driveway/patio and roofs) • Recharge Storage Provided (Subsurface leaching facilities) = 1,378 cf > 401 cf • 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. • Required Water Quality Volume Vwq = Dwq x A = (1.0 in)(1 ft/12 in)(5,250 sf) = 438 cf (drive/hardscapes) • Water Quality Storage Provided (Three dry water quality swales) = 453 cf > 438 cf Page 8 of 9 EASTWARD COMPANIES - 9218 STORMWATER MANAGEMENT REPORT ASSESSORS’ MAP 138, PARCEL 74, ROUTE 6A, BREWSTER, MA SEPTEMBER 8, 2023 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 II 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 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.
