Rodney French Blvd 92 Fort Avenue 30 Emerson Avenue New Bedford, MA 02744 Salem, MA 01970 Gloucester, MA 01930 March 6, 2024 Yarmouth Conservation Commission 1146 Route 28 South Yarmouth, MA 02664 Dear Commissioners: The Massachusetts Division of Marine Fisheries (MA DMF) has reviewed the Notice of Intent (NOI) by John and Georgia Levantakis to replace a timber bulkhead with a vinyl bulkhead and dredge 98 cubic yards within the Parkers River at 5 Compass Drive in the Town of Yarmouth. The area behind the existing timber wall will require excavation to reduce the load on the wall. Then the existing timber sheets will be removed, with the new sheeting installed incrementally in the same location. The new vinyl bulkhead will be installed at the same elevation as the existing wall. The project was reviewed with respect to potential impacts to marine fisheries resources and habitat. The project site abuts salt marsh vegetation. Salt marsh provides a variety of ecosystem services, including habitat and energy sources for many fish and invertebrate species [1-2] The project site lies within mapped shellfish habitat for blue mussel (Mytilus edulis) and American oyster (Crassostrea virginica). A shellfish survey conducted by John Lowell on December 2, 2023 found American oyster and ribbed mussel in the project area. The Parkers River has been identified by MA DMF as diadromous fish passage, migration, and/or spawning habitat for alewife (Alosa pseudoharengus), white perch (Morone americana), and American eel (Anguilla rostrata) [3]. The Parkers River acts as winter flounder (Pseudopleuronectes americanus) spawning habitat. Winter flounder enter the area and spawn from January through May; demersal eggs hatch approximately 15 to 20 days later. The Atlantic States Marine Fisheries Commission has designated winter flounder spawning habitat as a “Habitat Area of Particular Concern” (HAPC). In the previous stock assessment, the winter flounder stock was classified as overfished with spawning stock biomass in 2019 estimated to be only 32% of the biomass target [4]. Spawning stock biomass in 2021 was estimated to be 101% of the biomass target based on a new recruitment stanza focusing only on the past twenty years [5]. Given the new status of the winter flounder stock, every effort should be made to protect the species and its spawning habitat. MA DMF offers the following comments for your consideration: 2 • A time-of-year (TOY) restriction should be observed on all in-water, silt-producing activities such as dredging to protect sensitive life stages of winter flounder. No in-water, silt-producing activities should take place from January 15 – May 31 of any year [6]. • MA DMF recommends the top of the dredge slope maintain a buffer of at least 25 feet from any bordering salt marsh to reduce the risk of slumping and erosion impacts to this resource. The proposed dredge footprint does not meet this recommendation. • MA DMF recommends that the top of the slope be no closer than 25 feet from the MLW line. Dredging the toe of the slope near the MLW line may result in the slumping of the intertidal habitat. • Appropriate containment measures should be employed to prevent siltation in the marine environment during dredging activities. • Any activities requiring a barge should be restricted to 2 hours before and after high tide to prevent barge grounding in mapped shellfish habitat. • Fuel spills from refueling of construction equipment will adversely impact sensitive resource areas. Impacts to resource areas can be avoided by prohibiting all land-based equipment from being refueled on-site. If equipment is refueled on-site, adequate containment and clean up material should be required to minimize impacts.
