Part of the strategy for reducing the impacts of impervious surfaces and educating various sectors of municipal and county government in the Troy Brook watershed included developing a program that utilized a case study of stormwater management at Department of Public Works (DPW) yards. The Parsippany-Troy Hills DPW facility in Morris County is approximately 3 acres and 2.1 of those acres is impervious surface. Through the installation of stormwater Best Management Practices the DPW achieves a theoretical complete stormwater disconnection during the 1.25-inch rainfall event in two hours (the New Jersey water quality design storm).
