Tucson Mountains

To provide comments on this watershed for consideration in the Floodplain Management Plan, contact Greg Saxe
Planning Manager
(520) 724-4633.
The Tucson Mountain watershed drains the eastern slopes of the Tucson Mountains and includes numerous washes that are tributary to the Santa Cruz River. The Tucson Mountains are rocky and have steep canyons that spill out onto alluvial fans before widening further onto the geologic floodplain under natural conditions. Development in low-lying areas is particu-larly at risk, and residents in these areas are encouraged to obtain flood insurance. All residents of this area should prepare for road closures when water is flowing and plan ahead to find alternative routes. There have been numerous swift water rescues in this area due to people trying to drive on flooded roads. This watershed is comprised of 34,339 acres and contains 810 acres of SFHA, 888 acres of locally identified floodplain and 2,575 acres of Pima County Regulated Riparian Habitat.
