Rillito Creek

To provide comments on this watershed for consideration in the Floodplain Management Plan, contact Greg Saxe
Planning Manager
(520) 724-4633.
The Rillito Creek begins at the confluence of the Tanque Verde Creek and Pantano Wash. Its downstream terminus is the confluence with the Santa Cruz River. The Rillito Creek water-shed also includes many of the Catalina Foothills watercourses as well as watercourses that originate in the City of Tucson. Rillito Creek plays a significant role in groundwater recharge. Excluding the Tanque Verde, Pantano and Foothills watersheds, this watershed is comprised of 16,881 acres. Rillito Creek has been largely contained in channel by numerous flood control projects, which have resulted in a string park connected by The Loop bike path. This watershed contains 3,821 acres of SFHA, 409 acres of locally identified floodplain and 763 acres of Pima County Regulated Riparian Habitat.
