Abstract
Cumulative impacts to wetland and coastal ecosystems is of increasing concern to environmental managers, the academic community and the concerned citizenry. The quantification of cumulative impacts is problematic due to the diffuse nature of the contributing factors. Since 1988, the Virginia Institute of Marine Science (VIMS) has been collecting data on the impacts to Virginia tidal wetlands from erosion control and shoreline development projects. For each project subject to the Joint Permit process, with the exception of private open pile piers, the Wetlands Advisory Program has quantified direct impacts for various development activity categories on 18 separate vegetated and nonvegetated wetland community types and subaqueous bottom. These data are further classified into proposed impacts and permitted impacts (permitted by Wetlands Boards and/or the Virginia Marine Resources Commission). Additional information related to the project which is contained in the database includes the primary and secondary waterways adjacent to the project site, the watershed, project location (city or county), total project cost, the stated purpose of the project, permit application number, and the amount of required compensatory mitigation by community type.
