Manalapan and Matchaponix Watershed Preliminary Flood Damage and Mitigation Report

Flooding DamageThe county of Middlesex entered into an agreement with the United States Department of Agriculture – Natural Resources Conservation Service (NRCS) in September 2008. The purpose of the agreement was to develop a preliminary watershed study to examine the nature and extent of flooding and develop preliminary solutions for flood damage reduction. The County of Middlesex provided funding to NRCS to conduct this study.

Primary accomplishments of the study were to describe the watershed setting including watershed and subwatershed size and location, municipalities, land use/land cover, hydrologic soil groups, flood hazard zones, historic peak annual stream flow and flood damages, detention basin locations as well as the present and future condition runoff curve information. Other information provided includes the a summary of the preliminary damage assessments from the July 17, 2005 flood, National Flood Insurance Program (NFIP) flood claims and repetitive flood claims as well as the number of NFIP policies and structures insured by municipality. Recommendations for future study and action are given at the end of the Report.

Lambertville – Swan Creek Watershed Preliminary Flood Damage and Mitigation Report

South Union Street flooded June 2006The City of Lambertville entered into an agreement with the United States Department of Agriculture, Natural Resource Conservation Service (NRCS) in January of 2006. The purpose of the agreement was to study the feasibility of an engineering solution to the Delaware River back-flooding into Swan Creek that impacts neighboring homeowners and businesses along Swan Creek. The City of Lambertville provided funding to NRCS to conduct this study.

Primary accomplishments of the study included a structure-by-structure engineering survey of approximately 200 structures in the flood damage area along Swan Creek and a preliminary evaluation of available flood mitigation alternatives. A recommendation was made that further study and a detailed analysis of benefits and costs, along with an environmental assessment of each alternative and its acceptability to the public, be completed. This report is intended to provide a framework for that analysis and assessment.
