About the entity

Brown and Caldwell
Brown and Caldwell, Inc. provides environmental engineering, consulting, and construction services serving municipal, private, and federal organizations in the United States.


 Brown and Caldwell, a leading environmental engineering and construction firm, has opened a new office in downtown San Diego to better serve municipal, federal, and private sector water and wastewater clients in the San Diego area. The new office is located at 450 B Street.

"Our new office reflects our continued commitment to serving and supporting the greater San Diego metro area. By moving our nearly 50-person operation to this iconic location in the heart of San Diego, we’ll be in a greater position to serve our clients and positively impact communities throughout San Diego County,” said Brown and Caldwell’s San Diego Leader J.P. Semper.

Brown and Caldwell’s history in the area dates back nearly 70 years, including co-authoring San Diego’s first plan for a centralized wastewater system to safely treat and dispose of wastewater via one centrally-located treatment plant and outfall (i.e., the Point Loma Wastewater Treatment Plant and Ocean Outfall). The 1952 report entitled, "Report on the Collection, Treatment, and Disposal of the Sewage in San Diego County, California,” served to address San Diego’s most significant environmental and sanitary obstacle of the time.

In the decades since, Brown and Caldwell has continued to serve San Diego with innovative planning, engineering, and construction solutions to the area’s most complex water and environmental challenges related to drought resiliency, aging infrastructure, as well as environmental stewardship and compliance. The firm currently serves as a key member of the program management team delivering Pure Water San Diego, a phased, multi-year program that will provide one-third of San Diego's water supply locally by 2035.
