Abstract
Use of GIS in Storm Water Management Track: Water, Wastewater, and Stormwater Author(s): Mohammad Fatemi In 2005, the City of Thousand Oaks developed a Storm Drain Master Plan using ArcGIS and the Sormwater Geodatabase model. The City chose a GIS-based Plan in order to benefit from GIS functionality such as overlays with other City data, and distributed access and updates to the information once it was loaded into the City's multi-user geodatabase. Three information products were key outputs: anAtlas maps of the City's storm drain system, a hydrology study to determine potential runoff, and a hydraulic model to examine potential deficiencies due to system age and existing capacity. To build the data used in the geodatabase, georeferenced record drawings were utilized for infrastructure and LIDAR data for topography. The hydrology study was based on the topography, and new watershed areas were defined. The hydrologic model resulted in a deficiency report that can be used to guide future capital improvement spending.
