The Troy Brook watershed located in Morris County is within the larger Whippany River Watershed, which then discharges to the Passaic River. The Troy Brook watershed is approximately 16 square miles, with 24 miles of river and more than 400 acres of lakes, including Lake Parsippany and Mountain Lake.

Parsippany-Troy Hills – Municipal Efforts
At the Parsippany-Troy Hills Municipal Building two rain gardens were installed in September 2009. Volunteers from the community and the Whippany River Watershed Action Committee were trained on rain gardens and how they help address stormwater problems.
At the Parsippany-Troy Hills Department of Public Works Yard Turfstone pavers were installed on an emergency road. The road previously allowed stormwater to flow directly to the Troy Brook. Turfstone pavers are interlocking pavers that are placed on roads or parking areas that do not receive heavy traffic. The pavers allow grass to grow between them, decreasing the amount of runoff from the area.
Also installed at the Department of Public Works is a 2,000-square-foot bioswale that treats 1.6 acres of parking lot during the 10-year storm (5.23 inches for Morris County) along with some rooftop runoff and washwater from vehicle washing.
Normandy Office Complex
Normandy Parking Lot Project (2.9MB PDF) – Powerpoint of the project
At the Normandy Property office complex on Cherry Hill Road a portions of the upper parking lot were fitted with pervious pavement to allow for more ground water infiltration and disconnection of stormwater. Porous pavement is a permeable pavement surface with gravel underneath. The gravel temporarily stores stormwater runoff prior to infiltration into the soil. By only using porous pavement on select portions of the parking lot it allowed drainage of the parking lot without the cost of retrofitting the entire parking lot.
Tivoli Garden Complex
Rain Gardens were installed at The Tivoli Garden Apartment Complex, Parsippany-Troy Hills, Morris County, NJ in the summer of 2011. The Troy Brook is running just behind the row of cars parked in the picture below.
