Description: This stormwater infrastructure data was collected and compiled for the City of Longview, Texas. Information was collected and compiled in a variety of ways including GPS unit, locating the structures on aerial imagery, digitized georeferenced plans and record drawings, and the knowledge of members of the municipality. The points, lines, and polygons, show the locations and connections of various features of the stormwater infrastructure, as well as some points included for additional information. Drainage systems were mapped using ArcMap 9, 9.3.1 and 10 to establish the connectivity of the stormwater features, and to show where runoff from impervious surfaces in various subwatersheds within an urbanized area eventually enters the receiving water.
