Minimizing Environmental Impacts Through Stormwater Ordinance and Site Plan Regulation
Using the Oyster River watershed as a pilot test case, this study evaluated the financial and ecological benefits of adopting the enhanced model stormwater standards to reduce future pollutant loads resulting from expansion of impervious area in the watershed over the next 30 years. The standards would apply to new development and redevelopment projects subject to site plan and/or subdivision review by the Planning Board. This includes most, if not all, commercial or mixed use development projects and residential multi-family or subdivision projects.
In addition to significant pollutant load reductions in the watershed, results found that early adoption of these model standards could result in substantial cost
savings through future cost avoidance in not having to construct numerous stormwater BMP retrofits to meet future regulations.
This research project was conducted by the UNH Stormwater Center in cooperation with VHB and the Strafford Regional Planning Commission (SRPC). The project was funded by EPA.
