Abstract

he Commonwealth of Virginia currently has no regulations in effect to restrict the discharge of waste from vessels in state waters. This poses concern as Virginia continues its efforts to improve water quality in the Chesapeake Bay. The degradation of critical environmental habitat is accelerated by the introduction of waste, which in turn threatens the ecological, aesthetic, and commercial values of Virginia's waters. The purpose of this project is two-fold. First a comprehensive review of regulatory statutes in states enforcing "no discharge" zones (NDZ) was conducted. This product is delivered as a separate document. Second, a large-scale inventory of environmentally sensitive areas for consideration in the delineation of "no discharge" zones within Chesapeake Bay waters has been produced. A large digital database was generated at the Comprehensive Coastal Inventory (CCI) Facility at the Virginia Institute of Marine Science (VIMS). The database includes several valuable inventories which historically have been archived as hardcopy maps. This effon developed methodologies to transfer these data to digital format. The database has been designed in an Arc/Info Geographic Information System (GIS) format. A description of the database layout, data sources, and coverages is presented. The development of the NDZ database is viewed by the Center for Coastal Management and Policy as Phase 1 in a series of anticipated activities which will ultimately provide the necessary resources to implement management policy in this area.
