Lower Linganore Creek Stream Corridor Assessment Survey

摘要

The Linganore Creek watershed is located in the Lower Monocacy watershed, an 8-digit watershed in Frederick County, Maryland. It is divided into the Upper Linganore Creek and the Lower Linganore Creek watershed. According to Table 7-12 of the 2003 Frederick County Annual Report for NPDES Storm Sewer System Permit No. MD0068357, the Lower Linganore Creek watershed encompasses approximately 23,894 acres. Frederick County Division of Public Works hired the Maryland Department of Natural Resources (DNR) to complete a Stream Corridor Assessment (SCA) survey of the stream network within the watershed. This assessment is necessary to complete the required tasks under the Countys National Pollutant Discharge Elimination System (NPDES) storm sewer system permit under the Clean Water Act. The results of this survey will be used by Frederick County DPW to determine problem areas that could be fixed through community restoration, stormwater management (SWM) facility retrofits, and to reduce untreated impervious urban areas by 10 percent. The County plans to use the data to target areas where more involved stream restoration and stormwater management facility retrofit assessments are required.
