Water Resources
We partner with clients to thoughtfully navigate regulatory complexities and provide integrated and enduring solutions for the supply and conveyance of treated and recycled water, wastewater, watershed management, and flood control.

Our work has been recognized with awards from the National Association of Environmental Professionals, Association of California Water Agencies, American Society of Landscape Architects, and International Association for Public Participation.
