Waterfront Development and Potential Impacts to Aquatic Habitat - A Planning Tool for Evaluating Resource Sensitivity

Community development along the waterfront challenges managers each day to balance expansion and economic growth with preservation of aquatic resources. There are few guidance tools available to managers to improve how decisions are made. This is especially true in communities experiencing development pressure. This project begins to address this issue with the development of a protocol that considers specific criteria in a waterfront landscape that collectively appraise the potential risk of development to sensitive aquatic resources. The protocol evaluates conditions on the landscape based on three major categories: existing land use, impacts to sensitive habitat, and potential impacts to water quality. A GIS-based model implements the protocol and ranks criteria based on a designated set of rules and conditions. The ranking system assigns points based on presence or absence within an analytical unit measured 600 meters longshore, 90 meters inland, and up to 200 meters seaward of the shoreline, depending on creek width. A site is evaluated for each of the three major categories. Within each category, several criteria are mapped independently and ranked. The model output classifies shoreline segments as low, moderate, or high potential for impact to aquatic health based on the cumulative scores. While limited to available GIS data, the model in its development seeks surrogate data to substitute for data not available. As written, the model can be adapted as new digital data come online. Recommendations for future data inclusion are presented.Greenvale Creek in Lancaster County, Virginia was modeled to test the protocol. A series of maps and tables illustrate conditional impacts along 11 segments. The results are included in the final report. This project was guided by a technical advisory team composed of VIMS scientists. A steering committee comprised of planners, regulators, environmental managers represented the end user community and provided input to the model development.
