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.
From concept to completion, we assist with the planning, permitting, and implementation of water projects while minimizing impacts to the environment. This integrated approach saves our clients time and money and advances their strategic resource management and stewardship goals.
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.
