The Santa Rita Ranches operate in cooperation with the Santa Rita Experimental Range located to the west of the Santa Rita Mountains, in the upper Santa Cruz Valley. It was established in 1903 and is recognized as a principal site for research on the improvement and management of semiarid grasslands in the Southwest.

This floodplain study was prepared to identify the extent and magnitude of flooding within the boundary of the park under existing conditions. The results of the analysis and the associated hydrologic/hydraulic model will serve as the base condition model for all future developments to aid in the planning and design process.
