Rodney French Blvd 92 Fort Avenue 30 Emerson Avenue New Bedford, MA 02744 Salem, MA 01970 Gloucester, MA 01930 January 14, 2025 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 David Todesco to construct a vertical bulkhead, dredge 75 cubic yards, and replace a pier, ramp, and float within Parkers River at 172 Pawkannawkut Drive in the Town of Yarmouth. The project was reviewed with respect to potential impacts to marine fisheries resources and habitat. The project site lies within mapped shellfish habitat for American oyster (Crassostrea virginica). Waters within the project site have habitat characteristics suitable for this species. Land containing shellfish is deemed significant to the interest of the Wetlands Protection Act (310 CMR 10.34) and the protection of marine fisheries. 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) [1]. 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 [2]. 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 [3]. 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: • The applicant is proposing to install a bulkhead seaward of mean high water then fill in the intertidal area between the proposed bulkhead and the land. Filling of intertidal habitat will permanently convert habitat and will result in the loss of Commonwealth public trust tidelands. MA DMF does not support the proposed location of the bulkhead. 2 • A new pier and float has the potential to negatively impact nearby shellfish resources and fisheries in a variety of ways [4]. While some of these impacts can be avoided or reduced with best management practices, others are unavoidable and will result in permanent impacts to shellfish habitat and associated fisheries access. Support piles will directly displace shellfish habitat, and piles may cause further indirect impacts that negatively affect bordering shellfish habitat. Leachates from any pressure treated wood used for support piles or decking may also negatively impact nearby shellfish. Associated boating activity could result in prop dredging if the float is installed in insufficient water depth relative to the size of vessels using the structure. The support piles, float, and adjacent footprints will likely not be accessible to commercial or recreational fisheries. • While shellfish were not found within the project footprint, the subtidal area is suitable shellfish habitat. • A time-of-year (TOY) restriction should be observed on all in-water activities to protect sensitive life stages of winter flounder. No in-water, silt-producing activities should take place from Jan 15th – May 31st of any year [5]. • 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 [4]. The proposed dredging footprint does not meet this recommendation. • Instead of dredging, MA DMF recommends installing float stops so the bottom of a proposed float would be at least 2.5 feet (30 inches) above the substrate over mapped shellfish habitat at MLW [4]. • MA DMF recommends that all staging and storage of construction equipment and material be located on the upland side of the project site or on the construction barge. • 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.
