8 14-65 Sullivan Embankment Project Narrative The Sullivan property is located on Sea Meadows Lane and includes approximately 500 LF of shore frontage on Casco Bay. The residential home on the property is part of a well-established neighborhood. The entire property is zoned as low Density Residential and is entirely within the Shoreland Overlay District. Refer to the Site Pictures that start on page 10 and plans located in APPENDIX B Project Drawings that start on page 13. The project includes the stabilization of an existing coastal slope with geotextile, plantings and coir logs to address active erosion. The work serves to protect from further property loss that would eventually encroach upon the existing septic system. A. PURPOSE AND NEED OF PROPOSED IMPROVEMENTS An overview of site work is provided on Sheet C-0 SITE PLAN OVERVIEW. The primary activity stabilizes a section of the coastal embankment on the Sullivan property that is located on Sea Meadows Lane in Yarmouth. Several coastal trees are in danger of failing due to undermining of the roots system. If coastal erosion proceeds unchecked, the coastal trees and septic system will eventually be impacted. The proposed work also improves an existing access to the shore that will be used temporarily for construction access for the bank stabilization work. The access is necessary to maintain a safe passage to the shore for use by the property owner. Improvements are also made to the front lawn to control runoff on the property from Sea Meadows Lane. B. EMBANKMENT STABILIZATION The major elements of the proposed embankment stabilization are discussed below and shown on Drawing C-1 EXISTING CONDITIONS, with the proposed improvements shown on C-2 SITE PLAN and C-3 TYPICAL SECTION. Embankment regrading- The existing slope will be cutback to a 1.75: 1 slope. Excess material will be removed from the property. Slope Reinforcement and Plantings- The slope is further stabilized with a soil mat geotextile and plantings. Coir Logs-The toe of the slope is reinforced with biodegradable coir logs placed parallel to the slope. These densely packed jute tubes protect the slope from wave action in the short-term to minimize damage while the plantings get established. Less resilient than stone, but more cost effective, they need to be replaced periodically to function in the long-term. When replacement is required, they can be carried to the site and staked without the need for heavy equipment. Vertical Drains- Vertical drains are added where surface or groundwater is encountered. These are placed to collect and transport water to the toe of the slope. C. CHECK DAM WALKWAY Route (Refer to Sheet S-1). There is a natural drainage channel that transports runoff to the beach area. This is also the traditional access to the beach for the property and is currently improved with a timber walkway. In order to prevent damage to trees at the top of the coastal slope from construction activity all regrading operations will be undertaken from the beach. The Page 5 Yarmouth Shoreland Application

9 14-65 Sullivan Embankment existing channel will be used to get construction equipment onto the beach for the regrading operation and at the completion of the work will be improved as shown on the plan. To minimize damage to the beach and adjacent marsh during construction, the work will be undertaken by wide tracked vehicles during the winter and the vehicle path will be temporarily stabilized with mats at turning locations. D. VISUAL IMPACT CONSIDERATIONS The proposed embankment stabilization is a vegetated solution without the impact of stone armor or structure. Yarmouth Shoreland Application Page 6

15 APPENDIX A State & Federal Regulatory Correspondence Sullivan Embankment An NRPA Permit has been filed with Maine DEP and the Army Corps of Engineers. A copy of the permits received for the work will be provided to the Town as soon as they are received. DEP regulates work within 75-ft of the coastal wetland as defined by the Highest Annual Tide (HAT) line. The Army Corps of Engineers jurisdiction extends to work that is seaward of the HAT line. A letter of project notification has been sent to the Maine State Historic Preservation office for comment in accordance with Shoreland Application requirements. The response will be copied to the Town as soon as it is received. Based on a preapplication meeting with DEP (Chris Coppi) and discussion with the Yarmouth Code Enforcement Officer (Bill Longley), the removal of the trees whose root systems have been compromised and the drainage improvements to the front lawn are entirely within the purview of the Yarmouth Shoreland Ordinance. It is requested that the Town consider a Shoreland permit that is conditional on receiving the state and Federal permits so that the trees that are in danger of falling and creating additional erosion) and the drainage work to the front yard can be completed.
