Dams, Flood Controls and Water Resources Facilities

TRC has served the environmental and engineering needs of water resources market for 50 years, and our expertise is growing stronger in the Western United States. Our staff professionals have a long record of project experience to improve some of the nation’s largest water storage and delivery systems of reservoirs, aqueducts, power plants, pumping plants and treatment facilities. 

Today’s population growth and water shortages are a real problem in many areas of the country. TRC’s structural engineering services can help you address capacity needs by analyzing the adequacy of existing assets, locating and obtaining rights and permitting for new water sources and overseeing modifications and improvements to bring your community the water it needs through decommissioning or rehabilitating existing assets or constructing new containment, conveyance and treatment infrastructure. 

Dam safety and flood control is equally concerning in the advent of climate changes that cause high-magnitude storms. TRC can evaluate stability, seepage, inundation and breach hazards for dams and levees and deliver the design and construction to mitigate conditions. Our strong record includes a variety of emergency repair and rehabilitation projects for dams and setback levees that involved raising of levee roads, soil/cement/bentonite mixing, cutoff walls, reinforced concrete footing, floodwalls, seepage berms, earthfill, road grading, and rock slope protection.
