Corps Regional Sediment Management and Habitat Restoration: Cape May, NJ J. Bailey Smith National Planning Center of Expertise for Coastal Storm Damage Reduction 25 June 2008
Philadelphia District Regional Sediment Management 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
Philadelphia District Established 1866 Delaware River basin Parts of 5 states 9 million people 15,000 square miles 150 miles of coastline 550 miles Federal channels 1.1 million acres of wetlands 5 flood control dams 1.5 M park visitors/yr 1 canal, 5 bridges

Plover crossovers Lower berm elevation “Plover” ponds Modification of dune fencing/planting Habitat vs. Storm Protection Modifications to Enhance Plover Nesting and Feeding Habitat
Piping Plover Ponds - Old dune relocated seaward - Ponds excavated - Minimal vegetation planted around 1 pond April 2005 August 2005 Total of 3 ponds created ranging in size from 1-4 acres
Creation of Plover Habitat at the Cape May National Wildlife Refuge l Create an “overwash area” for piping plovers updrift of Cape May Inlet jetties l No net loss of plover nesting habitat l Agency collaboration l Application of habitat creation for other NJ beachfill projects

Build It and They Will Come l Until 2007, no recorded nests in Wildlife Refuge l 2007 nesting occurred but all chicks lost to predation l Birds utilized nesting habitat within a few months of creation l Nor’easter flooded out nests in Coast Guard beach, but nests in new habitat area survived l USFWS considers this a success and will maintain project in future and will maintain project in future
