Shoreline Situation Reports for Tidewater Localities
Project Description as Proposed:
The Shoreline Situation Reports are an important resource for local and state planners and regulators of Tidewater Virginia. The data collected enhances their ability to make decisions regarding coastal construction, land use planning, and implementation of environmental legislation. The proposed project will complete the Shoreline Situation Reports for five Tidewater cities and localities. They are: Chesapeake, Portsmouth, Gloucester, New Kent, and King George. Data collection is complete for each jurisdiction except the City of Portsmouth, where a short segment of shoreline remains to be surveyed. This project will provide funds to complete necessary field work, process all data, perform QA/QC, generate and publish all elements of the electronic Shoreline Inventory (Shoreline Situation Report) for the designated counties. This includes maps, tables, summary report of methods, metadata, and GIS data which will be posted to a dedicated website maintained by the Center for Coastal Resources Management. GIS data will also be made available on CD to VA CZMP for inclusion in Coastal GEMS. The format for the website can be viewed at http://ccrm.vims.edu/gis_data_maps/shoreline_inventories/index.html.

Project Summary Provided by Grantee:
This project funded the continued development of Shoreline Inventories for five new Tidewater cities and counties in Virginia. This effort is an ongoing initiative to develop Shoreline Inventories for all tidal water localities within the Chesapeake Bay Watershed. This effort included the counties of Gloucester, New Kent, King George and the cities of Chesapeake and Portsmouth. When proposed most of these jurisdictions had all field data collection complete, but no effort to process data had begun. Over the course of the last 12 months data has been processed and verified through a consistent set of quality control and assurance measures. Based on the data collection, summary statistics reporting the condition of shoreline in each locality were generated. Maps were also generated that illustrate the conditions surveyed in the field. These products along with a summary report and all GIS data were added to Chesapeake Bay Shoreline Inventory website at this url: http://ccrm.vims.edu/gis_data_maps/shoreline_inventories/index.html
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 (xxx_lubc). The second reports shoreline structures that are collected as arcs or lines (xxx_sstru). The final coverage includes all structures that are represented as points (xxx_astru).
The coverages use a shoreline basemap generated in-house from the Virginia Base Mapping Program's high resolution imagery and digital terrain model from 2007. 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.
The website provides access to all downloadable files. Links at the bottom of the page direct users to a final summary report (pdf), GIS files (shape files), metadata (FGDC compliant), summary statistics (pdf), and maps (pdf).
