Few California engineering firms can claim as long and successful a track record as MacKay & Somps. Founded in Sunnyvale, California, in 1953 by Donald G. MacKay and George E. Somps, the firm helped drive the spectacular growth which occurred in the Santa Clara Valley after World War II. Our company created more subdivision lots in the South Bay region than all other engineering consultants combined.
Don MacKay and George Somps retired many years ago, but today’s management team retains the same successful business philosophies that have made our company one of the largest and strongest private civil engineering firms in Northern California - we are dedicated to providing the highest quality service to homebuilders, land developers and public agencies. Our goal is to see that our clients’ projects get built, efficiently and successfully.
Over the decades, the firm's expertise and reputation for success helped fuel the expansion of its professional and geographic areas of practice. Click here to see a map of our Service Area.
- The Pleasanton Office was established in 1962 and today serves as the company headquarters, directing public infrastructure and private land development projects in the greater Bay Area and the southern portion of California's Central Valley.
- From our Roseville Office, we serve the northern part of the Central Valley and the greater Sacramento region where MacKay and Somps has been established since 1975.
We have successfully completed thousands of land use, public infrastructure, and sustainable projects for clients throughout Northern California and the Central Valley. MacKay & Somps has consistently been listed among the top 250 design firms in the United States by the Engineering News Record (ENR). Almost half of our employees are licensed professional engineers and/or surveyors.
“In the early days, it wasn't unusual for us to bring a tentative map to a city council meeting, get their comments, run it back to our office, make the change and bring it back to the council for approval that same night. That commitment and drive to get our clients projects approved and built exists here today.”
