The property owners have recently determined that the existing deck on the south side of the dwelling within the 50-100’ buffer requires reconstruction due to disrepair and loss of structural integrity. The homeowners would like to request permission to reconstruct the deck in place with the addition of a 2-foot cantilevered section off the south side. The previously-approved walkway will then be shifted 2 feet south of its previously-proposed location (remaining within the 50-100’ buffer zone). The change to the deck and walkway will reduce the previously-approved mitigation area (which exceeded a total of 3,000 sf) by 73 square feet. Please review the revised plan and let us know if you have any questions.

Lawn will be removed, the area will be seeded with a native mix of cool and warm season grasses and wildflowers, and planted with native shrubs. • An additional 1,445 square feet within existing naturalized areas will be over-seeded with native grasses and planted with native shrubs where an understory shrub canopy layer is lacking. These naturalized areas a steeply sloping and significant runoff from upland portions of the property and deep shade have made it difficult for understory vegetation to thrive. Planting above the slope (described above) will help to slow runoff down before it reaches the slope and new planting will help stabilize soil and infiltrate runoff as it reaches the slope. • To help slow stormwater runoff, the area between the driveway and deck on the south side of the house will be regraded to create a pervious walkway with steps between landings. The walkway and steps will total 490 square feet within the 50-100’ buffer. Regrading will help slow stormwater runoff as it travels down slope and reduce the amount of existing erosion where the is currently heavy foot traffic around the house. • Regrading for stormwater management is also proposed on the north side of the house outside of the 100’ buffer. Though not in Conservation jurisdiction, regrading to slow and infiltrate stormwater runoff before it reaches the pond will offer another significant improvement to the resource area. • The property will be planted with a total of 193 native shrubs and 24 container-sized perennial grasses (see Plant Schedule below for details). • Temporary irrigation will be required for the first two to three growing seasons while plants establish. Once plants are established irrigation will be removed. REVISED NOTE: • 6/30/20: Existing deck to be reconstructed in place with the addition of a 2-foot cantilevered extension on the south side. The previously-approved walkway will shift location 2-feet to the south to accommodated the deck extension.

O’Reilly Associates, Inc . • This plan proposes removing 11 pitch pines, 2 white pines and 1 oak trees within 100’ buffer to the BVW to allow for the installation and use of solar panels. These trees were identified and marked for removal by a third party solar energy consultant. • Minor vista corridor management activities are proposed in the area marked on the plan. One (1) previous-cut and damaged oak and 2 pitch pines (3” and 5”, DBH) are proposed to be removed and replaced with native shrubs. • Greenbrier (Smilax rotundifolia), an aggressive native, is also present in patches along the top of slope. This Plan proposes not to eliminate, but to manage greenbrier to reduce competition with other native species. All vegetation debris will be removed from the site and brought to an off-site disposal area.

After inspection of adjacent dead cherry, signs of root fungus cause concern for the health of the existing cherry that helps support and stabilizing of the bank. Propose no more than 10% reduction/year to avoid water sprout growth. We would also like to remove the adjacent dead cherry as a safety issue. Sincerely, Tom Coburn Coburn landscaping MCA # 101805 June 26, 2020 Mr. Michael Tobin Conservation Commission Chair Town of Brewster 1657 Main Street Brewster, MA 02631 Re: Field Modification MassDEP File #: SE 9-1824 Property location: 289 Crocker Lane Dear Mr. Tobin: I am writing to request a minor field modification to the approved scope of work at 289 Crocker lane under order # SE 9-1824 to add a small (2.5-foot-tall) retaining wall on the east side of the new garage and dwelling. The proposed retaining wall will be a block wall (typical construction), extending 60- linear feet along the side of the property to retain the existing grade and remediate drainage concerns around the new house. All proposed work will remain within the existing Limit of Work. Two small black cherry trees and one oak tree (all in poor condition) will be removed for the installation of the retaining wall and will be replaced 1:1 with native trees within the buffer zone to the coastal bank. The total amount of previously-approved mitigation planting will remain the same as previously proposed. To accommodate the layout of the proposed wall, 40 square feet of mitigation will be shifted from the east side of the property to the west-side mitigation planting area (closer to the resource area). To further address drainage concerns (potential pooling around the house, deck, and garage) a rain garden will be installed on the south side of the garage between the garage and the recently installed septic leach field. One NDS dry well will be added below the proposed driveway to capture roof runoff from the garage. Please review the attached photos and revised plan and let us know if you have any questions. Sincerely, Theresa Sprague BlueFlax Design LLC Location of proposed retaining wall east of the garage. Two black cherry trees and one oak tree (in poor condition) will be removed for installation of the wall and replaced 1:1 within the buffer. 4.0' 7.0' 1 0 . 0 ' 2 . 0 ' 3.0'10.0'25.0' 3.0' 8.5' Add step, lower grade between steps Lower existing grade at top of slope to reduce pitch Proposed retaining wall 2.5' tall Proposed retaining wall 1.5' tall Garden bed Proposed AC Condensers Proposed generator Existing previous mitigation planting Lower grade around step +/- 6" to match bottom step.
