STORMWATER MAPPINGPOLLUTION PREVENTION PLANNING
The �gure on the left depicts a GIS generated map of a University in Virginia. The “background” layer shows the di�erent drainage basins impacted by
stormwater runo�. The yellow line depicts the area of the stormwater permit. Also note that the map shows impermeable surfaces such as buildings and
paved areas.
The �gure on the right depicts a GIS site plan of a University Facilities Operations Plant. The map shows the outline of the building, paved areas,
dumpsters (green diamonds), catch basins (blue), conveyance (green dotted lines), storage areas, the boundary of operations (red line) and the direction of
