Retrofit Sites & Recommendations


The project team assessed 110 potential stormwater retrofit opportunities at 51 project sites in the watershed. Sites were almost entirely located on the University campus, where the dominant fraction of the watershed’s impervious cover is found. For the town section of the watershed, the focus will be on future development rather than retrofits.

Each of the 51 retrofit opportunities were evaluated using professional judgment and the following technical factors: impervious area treated, pollutant removal capability, runoff reduction estimates, cost, and maintenance requirements. The project team then reviewed the 51 sites with respect to non-technical factors such as feasibility, educational or demonstration potential, and opportunity. Out of these discussions came a “Top Ten” list of priority retrofits, for which the team created 25% design conceptual drawings. The intent is not necessarily to implement these practices exactly as designed, but to inform the design process as building and renovation take place on campus. See project technical report for more information.
