John Wallace formed John L. Wallace & Associates as a one-person, home-based business in 1984. From a small house in San Luis Obispo, California John L. Wallace & Associates has steadily grown into a multi-disciplinary engineering, design, surveying, and planning firm now known as Wallace Group.

John started Wallace Group after a career in public works in both Los Angeles and San Luis Obispo Counties that spanned more than two decades. John’s extensive experience in the Los Angeles Flood Control District and as the Office Engineer of San Luis Obispo County earned his newly formed company a solid work base. He also shared his expertise as the Director of Public Works in the cities of Arroyo Grande, Pismo Beach and Atascadero. Wallace Group continues to work with these communities as well as additional community service districts along California’s Central Coast.

In 2002, Wallace Group acquired Swanson International, an innovative wastewater treatment design company. Wallace Group is now an industry leader in the design and use of Advanced Integrated Pond Systems (AIPS) and other environmentally sustainable technologies for wastewater treatment.

Over the years, the company has expanded to include services in Civil & Transportation Engineering, Construction Management, Landscape Architecture, Mechanical Engineering, Planning, Public Works Administration, Right-of-Way Services, Surveying/GIS Solutions, and Water Resources and employs over 50 people. The people of Wallace Group are at the heart of our success. As professionals and as contributing members of the communities we serve, we will continue to approach our work with integrity, quality and a dedication to service.
