Dear Commissioners:
The Division of Marine Fisheries (MA DMF) has reviewed the Notice of Intent by Clifford
Polly, 48 Grandview Drive, to extend an existing ramp and add three new pilings to support the
existing structure and float on the Bass River in the Town of Yarmouth. Work will be conducted
near high tide to prevent the barge from grounding. The project was reviewed with respect to
potential impacts to marine fisheries resources and habitat.
The project site lies within and adjacent to mapped shellfish habitat for soft shell clam (Mya
arenaria), quahog (Mercenaria mercenaria) and bay scallop (Argopecten irradians). Subtidal
waters within the project site have habitat characteristics suitable for these 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.
The Bass 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).
The 2020 Southern New England/Mid Atlantic management track stock assessment indicates
that although overfishing is not occurring, the stock remains overfished. Spawning stock biomass
in 2019 was estimated to be 32% of the biomass target [1]. Given the 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 NOI states that the new float location will match the current depth requirements for
piers of –3 feet MLW. However, the bathymetry in the project plans does not appear to
be recorded relative to a MLW depth of 0 feet. While the terminal section of the new
float would be in deeper water than the current float structure, it appears to be below this
–3 feet MLW threshold. Much of the new float area also appears to be below the
minimum 2.5 foot clearance recommended by MA DMF for floats installed over shellfish
habitat [2]. Depths below the new float footprint should be clearly defined for the
landward and seaward ends of the proposed new structure.
• MA DMF recommends the use of appropriate containment techniques to prevent siltation
in the marine environment during construction.
Questions regarding this review may be directed to Amanda Davis in our New Bedford office at
