These watershed areas varied from sparsely populated to fully urbanized. As part of this project, we prepared an Existing Facilities Inventory, geographically locating over 10,000 natural washes and major man-made drainage facilities. The condition, capacity, and ownership of these facilities were noted if the information was available, providing Pinal County with a useful tool, not just the location of the facility. This project identified drainage issues and provided recommendations for further analysis or mitigation measures. We also created a GIS overlay for the County identifying zones of special flood hazard types including ponding, alluvial fan areas, earth issues, and stream flow areas.
