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.
Flooding and erosion within the Ranch Estates subdivision during the 2007 summer monsoon season raised the concerns of homeowners. This study addresses the impact of recent improvements in the drainage area upstream; provides updated flood-hazard mapping for the area, and identifies mitigation measures that could be implemented by the affected homeowners to address their flood/erosion hazards.
This Technical Data Notebook has been prepared in support of a Letter of Map Revision application for a portion of the Friendly Village Wash. It includes detailed hydrologic and hydraulic analyses performed to determine proposed regulatory discharge rates at key locations along the Wash, and to determine floodplain limits.
