Project Overview

Role: Prime Consultant

M&J Engineering D.P.C. (M&J) provided engineering services to advance the Town of Brookhaven’s goal of improving the overall health of Patchogue Bay/Great South Bay in Patchogue, NY. Our design will minimize stormwater impacts to the bay by modifying the existing drainage infrastructure, disconnecting direct discharges at two locations, and re-routing stormwater discharge through green infrastructure that will encompass a living shoreline.
Project construction will include a stormwater bioretention swale with native salt-tolerant vegetation; rock-cored dunes with native beach grass and compatible sand; coir logs; marsh restoration with salt-tolerant vegetation and compatible sand; and low rock-sill breakwaters built at mean low water with strategic gaps. The cohesive living shoreline will stabilize the water’s edge, reduce erosion, and provide needed habitat to enhance coastal resilience and improve water quality. M&J provided:

Engineering design
Watershed analysis
Hydrologic, hydraulic, and water quality modeling
Permitting (NYSDEC, USACE, NYSDOS, Town of Brookhaven, and Village of Patchogue)
Suffolk County water quality protection and restoration grant reporting and support
Wetland mapping
Preliminary and final contract documents (plans and specifications)
Engineer’s construction cost estimate
Bid phase services
