Seasons of flood and drought, eroding shorelines, pollution, growing demand, and stringent environmental and security regulations are increasing the pressure at every point in the water cycle.

ESA partners with clients to thoughtfully navigate these complexities. Our team provides integrated, enduring solutions for the supply and conveyance of treated and recycled water, as well as wastewater reuse, watershed management, and flood control.

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

We work with clients to address aging dams, reservoirs, and other infrastructure systems to keep up with demand of a growing population’s residential and agricultural needs. Our team makes resilience planning in the face of climate change—including historic weather events, drought conditions, flood control, and sea level rise considerations—a top priority for dependable, long-lasting investments to critical infrastructure improvements.

Our work has been consistently 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.
