MWH Paul A. Marshall

California Region Sector Lead for Water Resources

MWH, now part of Stantec, has selected Paul A. Marshall as the California Region Sector Lead for Water Resources, a key statewide role targeted for implementation of creative and sustainable solutions to meet the state’s most pressing water resource challenges. He joins the company following a 28-year career with the State of California, where he last served as the California Department of Water Resource’s Bay Delta Chief, overseeing a $60 million annual budget and 94 staff.

“California’s ground and surface water supplies are under enormous challenges with competing demands to appropriately manage for the benefit of agriculture, cities, rural communities and the environment,” Marshall said. “MWH, now part of Stantec, has an unparalleled track record to delivering sound, sustainable and effective solutions to local, regional, state and federal agencies in California and I’m delighted to join the team and build upon those successes.”

Marshall brings a diverse background in water resource management including water supply, flood management, water quality and habitat use. His state career included 18 years with DWR and 10 years with the California Regional Water Quality Control Board. Accomplishments during this period included planning, permitting and managing installation of emergency salinity drought barrier; development and release of a new multidimensional hydraulic model (SCHSIM) and a new hydrology model (CalSim3); and modernization of a fish release facility and construction of a $7 million fish science building.

In his new role, he will be based in Sacramento, Calif., home of the company’s largest water resource planning group.
