Box 1517 East Dennis, MA 02641 508-385-1445 bobperry@capecod.net February 13, 2025 Town of Yarmouth Conservation Commission 1146 Route 28 South Yarmouth, MA 02664 RE: 1033 Great Island Road, West Yarmouth - SE 83-2460 To the Conservation Commission, Enclosed please find 7 copies of the plans submitted with the NOI revised as follows: Wilkinson Ecological Design plan - Improved diversity recommended by the Chair. Seaside goldenrod is added as a flowering salt tolerant plant that goes well with beach grass. Three dwarf chinkapin oaks to be placed approximately where the Japanese black pines are being removed. These will be planted as size - # 1, thus allowing the best chance of successfully taking root. Cape Cod Engineering, Inc. plan – The proposed concrete return discussed at the Feb. 6 hearing is replaced on this plan with a transverse artificial dune, dressed over with staked jute netting, planting with Am. Beach grass at 9 inches o.c. spacing. Also is a letter from the Great Island Homeowners Association, Inc., the direct abutter to the west. Given that the abutter is supportive of the originally proposed, very low profile return formation, we are submitting the transverse dune option to allow the Commission to continue to compare the efficacy of the two alternates. Please contact me directly with any questions. Thank you for your assistance with this project. Sincerely, Cape Cod Engineering, Inc. Robert M.

APPROXIMATELY THREE GROWING SEASONS WILL BE REQUIRED TO CONTROL AND/OR ERADICATE INVASIVE PLANT SPECIES. AFTER THREE GROWING SEASONS, MONITORING AND MINIMAL MAINTENANCE WILL BE ONGOING. 2. HERBICIDES ARE TO BE APPLIED BY LICENSED INDIVIDUALS ONLY. 3. ALL RESTORATION PLANTINGS WILL INCORPORATE EXISTING NATIVE SPECIES UNLESS OTHERWISE SPECIFIED IN THE APPROVED DOCUMENTS. 4. ANY DISCREPANCIES BETWEEN THE PLANTING SPECIFICATION AND THE PLAN, THE PLAN SHALL TAKE PRECEDENCE. 5. RESTORATION & MITIGATION AREAS WILL BE ALLOWED TO NATURALIZE. Beach grass planting will supplement existing vegetation, covering exposed soils and improving the stability of the Coastal Bank from wave energy and erosion. Beach grass planting atop sediment nourishment will extend the existing native vegetation across the site and create a denser wall of vegetation to protect the Coastal Bank from wave energy and erosion. Seaside goldenrod will add flowering plant diversity across the planting area. Refer to plan from Cape Cod Engineering for details on the sediment nourishment. BEACH GRASS TO BE PLANTED AT 24" ON CENTER - 2,600 SF NATIVE GRASS TO BE PLANTED count common name scientific name size 650 American beach grass Ammophila breviligulata bare root Japanese black pine (Pinus thunbergii ) is a small, non-native evergreen tree species from East Asia that is well adapted to the harsh conditions found on Great Island. It is seen as an ecological threat to native grasslands and dune systems, including the globally rare sandplain grasslands of coastal Massachusetts and the islands (Massachusetts Invasive Plants Advisory Group (MIPAG). Its resiliency to coastal conditions combined with high levels of seed production allow this pine to displace more beneficial native vegetation. Japanese black pine was designated as Likely Invasive in the State of Massachusetts and added to the State's Prohibited Plant List in 2022, and prohibited from sale after December 31, 2025. The trees will be managed using a flush cut and herbicide treatment method and hand removal of debris. The stump and root systems will be left in place to maintain the stability of the Coastal Bank. All seedlings and fallen pine cones will be removed by hand to decrease the number of seeds and re-sprouts that will require management. The project area will be monitored over time and any re-sprouts will be removed by hand. FIVE (5) JAPANESE BLACK PINE TO BE REMOVED 1 2/10/25 Revisions made to planting following 2/6/25 hearing.
