Project Description

Client: The Kiner Group
Location: Indian Wells, CA

Q3 Consulting, a PROACTIVE company, provided engineering services for the analysis and design for improvements to the Whitewater River, as part of the Indian Wells Crossing development project. The team prepared a basis of design report and channel improvement plans for proposed improvements to the Whitewater River Stormwater Channel (WWRSC).  The project reach within the WWRSC extends approximately 3,000 feet downstream (east) of Miles Avenue Bridge and 1,500 feet upstream (west) of the bridge. Q3 prepared detailed hydraulic analyses for existing conditions and the proposed modifications to the WWRSC to support the design of the proposed flood control improvements.   The detailed analyses included HEC-RAS hydraulic models, scour calculations, sediment transport modeling, drop structure evaluation and design, and local bridge element scour calculations.

The project proposes to widen the land area along the southerly bank of the WWRSC between Highway-111 and the WWRSC both east and west of Miles Avenue to provide more developable land area for the proposed Indian Wells Crossing commercial center and the proposed Indian Wells Resort.  Widening of the land area requires a realignment of the southerly bank of the WWRSC.  The proposed improvements include construction of approximately 12,000 linear feet of concrete slope lining, improvements to existing grade control structure, and several storm drain outlets to the WWRSC for local drainage.
