WASH CI Drainage Network

Status: NOT MAINTAINED Contact: GIS_IT, City of Tucson Information Technology GIS Services, 520-791-4747, [e-mail] Intended Use: For map display and provides finer level of detail than Pima County GIS library data layer WASHES. Supplemental Information: DATA QUALITY IS QUESTIONABLE because it has not been regularly maintained. Per Frank Sousa (Winter 2009), he would prefer to call this layer "drainage network" because it includes streets flow which may not be considered a watercourse. Started in 1999 it covered the municipal planning area, done in pieces startings with the core of the City. Was densified to make sure there was a line where there was 100 cfs flow or more for regulatory purposes. Streets flow mapping is incomplete. 7/10/2010 - loaded shapefile into EDITSDE geodatabase from Stormwater shapes folder. circa 1999 - Shapefile create by Frank Sousa in City of Tucson Stormwater from aerial photos, topography and ground knowledge. Additional edits done by Frank Sousa.
