Featured Stormwater Projects

Project

Dynamic 2-D Modeling
Various Clients

West Yost routinely conducts accurate hydrologic/hydraulic evaluations. This includes using dynamic 2-dimensional (2-D) surface flow modeling to more accurately predict results and to graphically demonstrate solutions. Recent projects include the Alamo Creek 2-D Flood Study for the City of Vacaville, and 2-D modeling for a 4,000 acre alluvial fan flooding analysis in the Mojave Desert for the Ivanpah Solar Facility project.

Project

Dry Creek Levee Relocation
City of Roseville, California

West Yost provided planning, analysis, environmental review, permitting, design, and construction management services for the Dry Creek Wastewater Treatment Plant Pond Levee Relocation. This project included the hydrologic and hydraulic evaluations of setting the pond levees 100 feet back from the Dry Creek bank in order to provide 100-year protection of the wastewater storage ponds while enhancing the flow-carrying capacity of Dry Creek in an environmentally sensitive manner.

Project

Ivanpah Solar Electric Generating Facility Stormwater Runoff and Sediment Transport Analysis
BrightSource Energy, Inc., California

West Yost prepared a 2-dimensional storm drainage model for a proposed 400 MW solar power project covering 4,000 acres in the Ivanpah Valley in the Mojave Desert in California. The project is situated on an alluvial fan located at the base of the Clark Mountain Range. Flood flows from the mountains are initially confined in incised channels, but once arriving on the alluvial fan, the flood flows are less confined and can take random paths across the fan.

Project

Citywide Storm Drainage Master Plan
City of Elk Grove, California

West Yost assisted the City by preparing a comprehensive storm drainage master plan (SDMP) to address population growth and protect residents from flooding.
