Clarksburg Special Protection Area, Montgomery County, Maryland


The Clarksburg Special Protection Area (CSPA) is located approximately 30 miles northwest of Washington DC in Montgomery County, MD. We are studying the use of stormwater BMP in these watersheds, focusing on Tributary 104, Soper Branch, Crystal Rock, and Ten Mile Creek. The CSPA is developing with housing developments while using the best available water quality protection measures during and following development to protect the streams in the area.

The CSPA study watersheds that are developing are Tributary 104, Tributary 109, Cabin Branch, and Ten Mile Creek. The undeveloped forested watershed is Soper Branch located in Little Bennett Regional Park; and the developed suburban watershed is Crystal Rock located in Germantown, MD. All of the study watersheds have continuous-record United States Geological Survey stream flow gages.

A Special Protection Area (SPA) is a part of a municipality that has been designated as having natural resources that are sensitive and therefore in need of special protection during development. The protection that is implemented within an SPA goes beyond what may be required by already established environmental regulations and guidelines.
