Sag Harbor Water Quality Improvement Project Plan (WQIPP)

Project Location: Sag Harbor, NY
Client: Village of Sag Harbor

NPV was hired by the Village of Sag Harbor to develop a Water Quality Improvement Project Plan (WQIPP) to identify and rank water quality improvement projects within the Village of Sag Harbor. The plan assessed the local land use, water resource conditions, watershed priority areas and developed water quality improvement projects within the Village of Sag Harbor for which Community Preservation Fund (CPF) funding was sought. NP&V the provided locations, feasibility, and cost estimates of potential projects to address non-point stormwater source abatements and reduction of stormwater with the use of green infrastructure improvements within the Village of Sag Harbor. The projects were then subsequently ranked by the cost per pound of Nitrogen removed for each project after modeling each project for effectiveness.

The Towns of East Hampton and Southampton awarded CPF grants in 2019 for the highest ranked projects, and N+P/NPV are currently preparing construction plans for various green infrastructure projects that will have significant benefits in reducing pollutant load to Sag Harbor. Project effectiveness will be evaluated with monitoring equipment to determine pollutant load reductions made by the green infrastructure systems and benefits to the receiving waterbody.
