Southern California Region

For more than 30 years, ESA has been providing environmental analysis and planning on a wide range of Southern California projects–from residential development to solar farms to regional water infrastructure.

From the largest water district in the western U.S. to the U.S. Bureau of Land Management’s pioneering fast-track solar approval process, our experts collaborate with a range of municipal, state, federal, Native American, and private-sector clients to deliver innovative solutions unique to Southern California.

Our success is grounded in the depth of our local experts, and supported by specialized staff throughout the company. We understand how important it is to be close to our clients from Inyo to San Diego County and everywhere in between, so we’ve strategically located our offices.
