Description: This data layer contains point features representing the approximate location of storm water structures located within Prince William County, Virginia. It was created to provide basic information regarding the type of storm water structure (inlets, manholes, end walls, risers, etc.), elevations of the structure, and maintenance responsibility of the structure. The layer was derived mainly from as-built plans, however some information may have been obtained through approved plans as well as field surveys.
