Providing stormwater management on existing County facilities is another tool to help reduce impacts to streams. This is important because the County is mandated by the State of Maryland under the NPDES – MS4 Permit to control stormwater pollution through watershed restoration.
Watershed Restoration Tools
Alta Vista stream restoration in the Rock Creek watershed before restoration, during construction, and after restoration (2003 ~ 2011).
Watershed Study and Restoration Project Selection
The County conducts watershed studies for each of the 8 watersheds in the County. Similar to going to the doctor for an annual check-up, the watershed studies look at the overall health and condition of each watershed and pinpoint where the issues are and how critical it is for repair.
The result is a Watershed Implementation Plan that summarizes the critical areas including the severity of the issue and what is needed for repair. Areas with the most critical condition is given the highest priority and restoration projects would be completed in those areas before moving on to restoring less critical areas.
