About | Cornerstone Engineering, Inc.
Our Firm
Since 1979, Cornerstone Engineering, Inc. has been in the business of serving clients. The company was originally founded as a civil engineering and land surveying company. Today, we boast a diverse work force that is engaged in planning and land development, carbon management and alternative energy, oil and gas production support, regulatory compliance, utility services, surveying and aerial drone services, and more. We distinguish ourselves as being client-minded, seeking to advance our client’s important issues by understanding their drivers and representing their interests well with regulators.
Cornerstone’s reputation is one of matching subject matter experts to our clients’ undertakings. Our full-time staff of engineers, surveyors, and technicians are joined by specialty consultants who are renowned in their field of practice and available to step in as-needed. This has proven to be a powerful arrangement, especially for clients who are poised to invest significant capital in the highly-regulated California environment.
Our clients view us as the go-to engineering firm in the San Joaquin Valley, entrusting us with program oversight for annual capital spend as well as regulatory compliance. We are proud to advise investors who contemplate large investments in California’s carbon sequestration and/or energy production. Cornerstone is similarly proud to evaluate ground-breaking technologies with applications in specialty water treatment, gas processing, carbon capture, and carbon-free steam generation.
We would welcome hearing from you to match your project needs with our supportive technical and regulatory staff.
