TOWN OF HEMPSTEAD COASTAL STORMWATER DRAINAGE STUDY

The development of a comprehensive analysis for the Oceanside hamlet was identified as a project as part of the NY Rising Community Reconstruction (NYRCR) Program within the Governor’s Office of Storm Recovery (GOSR). These plans outlined numerous projects to help rebuild more resilient communities in response to the severe storm damage.

H2M staff performed hydrologic and hydraulic evaluations for the drainage systems within the 3,000 acre study area to assess the abilities of these systems to convey runoff from the tributary watersheds. Computer modeling was utilized to calculate peak runoff rates for various storm frequencies. Based on the results of the computer modeling, we were able to recommend improvements to existing infrastructure to alleviate flooding during storm events, including increasing pipe capacity, installing pump stations, raising road elevations and developing green infrastructure techniques to improve water quality.
