The Berry Brook project in Dover NH is complete! This partnership between NHDES, UNHSC and the City has reduced the effective impervious area in the 185 acre Berry Brook urban watershed from 30% down to 10%. This unique partnership between academics, regulators and committed city staff has reduced best management practice implementation costs, increased the effectiveness, and led to more maintainable stormwater management systems. Combined, this project and these installations reduced pollutant loading of suspended sediment, phosphorous and nitrogen (total) by 17,514, 68 and 354 pounds per year, respectively.
The final report is available at: Berry Brook Final Report
