About the SCA survey

The Stream Corridor Assessment (SCA) survey was developed by Maryland DNR's Watershed Restoration Division as a tool to help environmental managers identify environmental problems and prioritize restoration opportunities on a watershed basis. As part of the survey, trained personnel walk the watershed's entire stream network and record information on a variety of environmental problems that can be easily observed within the stream corridor. Common environmental problems documented in the survey include: eroding stream banks, inadequate stream buffers, exposed pipes, altered stream channels, fish migration barriers, pipe outfalls, in-stream construction sites and trash dumping locations. *

Reports on Exposed Pipes

AWS has adopted the SCA survey protocol and conducted surveys during April and early May of 2004. Preceding the survey, we prioritized sub-watersheds of the larger Anacostia watershed using biological assessment survey reports prepared by Montgomery and Prince Georges Counties. The Sligo Creek sub-watershed, one of the most polluted in the area, was selected for the first survey. Since our primary concern is sewage inputs into the river, severe cases of exposed pipes are reported to the Washington Suburban Sanitary Commission (WSSC). We have found 67 exposed pipes (breakdown-probably sewage pipe: 3, sewage pipe: 56, unknown: 2, water supply: 6). Listed below are reports which were sent to WSSC.
