Regional Sediment Management (RSM)
      A systems-based approach to managing sediment
resources within the context of regional strategies (watershed,
estuarine, coastal) that address integrated sediment needs
and opportunities.

Three focus areas:
     - Coastal
     - Dredging & Disposal
     - Watershed Sediment Management

      Creation of Plover Habitat at the Cape May
               National Wildlife Refuge

   Create an “overwash area” for piping plovers updrift of Cape
    May Inlet jetties
   No net loss of plover nesting habitat
   Agency collaboration
   Application of habitat creation for other NJ beachfill projects

           Build It and They Will Come

 Until 2007, no recorded nests in Wildlife Refuge
 2007 nesting occurred but all chicks lost to predation

 Birds utilized nesting habitat within a few months of creation

 Nor’easter flooded out nests in Coast Guard beach, but nests
  in new habitat area survived
 USFWS considers this a success

  and will maintain project in future

               Restoration Summary
•Meadows and Wildlife Refuge habitat restoration successes
•Collaboration with resource agencies
•Plover restoration features can be effective additions to
      some coastal projects
•Effective ‘balance across business lines’ and regional project
integration including shore protection, ecosystem restoration
and navigation projects
   •knowledge applied towards developing potential strategy
   for shoreline protection needs
