This data layer began as being ONLY those drainageways in Green Valley. The layer has since been expanded to include drainage channels in other areas of the county. The gv in the layer name is a legacy of the initial extent of the layer. The coverage version of this layer includes interior polygons that can be identified by GVDWKEY=0.
Lineage: Initially created as a shapefile the layer has since become a feature class in a geodatabase.
