    The Shoreline Inventory Summary Tables quantify observed conditions based on river systems, such as the combined length of linear features (e.g. shoreline miles surveyed, miles of bulkhead and revetment), the total number of point features (e.g. docks, boathouses, boat ramps) & total acres of polygon features (tidal marshes)

    The data inventory developed for the Shoreline Inventory is based on a three‑tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. Hand-held GPS units are used to log features observed in the field. Three GIS coverages are developed from the GPS field files. The first describes land use and bank conditions (hamp_lubc). The second reports shoreline structures that are collected as arcs or lines (hamp_sstru). The final coverage includes all structures that are represented as points (hamp_astru). The coverages use a shoreline basemap generated in-house from the Virginia Base Mapping Program’s high resolution digital terrain model from 2009. The shoreline is re‑coded to reflect features and attributes observed in the field. The metadata file accompanies the coverages and defines attribute accuracy, data development, and any use restrictions that pertain to data

    Delaware Shoreline Inventory: Appoquinimink River, Blackbird Creek, St. Jones River

    This shoreline inventory is developed as a tool for assessing conditions along primary shoreline in three watersheds that discharge into Delaware Bay. Field data were collected between September 11-13, 2007. Conditions are reported for three zones within the immediate riparian river area: riparian land use, bank and buffers, and the shoreline. A series of maps, tabular data, and GIS files are posted to a website and available electronically to serve as a resource to all managers and planners within the three watersheds. The survey provides a baseline to which future conditions can be compared and tracked through time. Access report via Download tab

    The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. GPS registered videography was used to collect data on conditions observed in the field. Three GIS shapefiles are developed from the GPS field files. The first describes land use and bank conditions (Suffolk_lubc). The second reports shoreline structures that are collected as arcs or lines (Suffolk_sstru). The final shapefile includes all structures that are represented as points (Suffolk_astru). The shapefiles use a shoreline basemap generated in-house from the Virginia Base Mapping Program’s high resolution digital terrain model from 2009 and 2011 (where available). The shoreline is re-coded to reflect features and attributes observed in the field. The metadata file accompanies the shapefiles and defines attribute accuracy, data development, and any use restrictions that pertain to data

    The Shoreline Inventory Summary Tables quantify observed conditions based on river systems, such as the combined length of linear features (e.g. shoreline miles surveyed, miles of bulkhead and revetment), the total number of point features (e.g. docks, boathouses, boat ramps) & total acres of polygon features (tidal marshes). This particular set of Summary Tables includes tidal marshes only as an amendment to the 2010 Prince William County Summary Tables. Dominant plant community types were primarily determined during 2012 field surveys from shallow-draft boats moving along the shoreline. Land-based surveys were performed in some locations
