Implemented Stormwater Control Measures, ACCD

Shows the locations of Stormwater Control Measures (SCMs) that were implemented as a condition of National Pollutant Discharge Elimination System (NPDES) and Erosion and Sediment Control General Permit (ESCGP) permits within Allegheny County, PA. Specifically, this data set consists of SCMs associated with constructed permits that were terminated by the Allegheny County Conservation District (ACCD). Features were digitized using paper and/or digital as-built plan drawings, where available, received as part of the Notice of Termination (NOT) submission process. SCM data was obtained from submitted NOT forms which are also required as part of this submission. Construction of SCMs are often required by NPDES and ESCGP permits to manage excess stormwater, created by increased impervious area, by treating rate, volume, and/or water quality.
