Southern California's Trusted Infrastructure & Public Works Surveying Firm

WHO WE ARE

29 Years of Experience Building Southern California’s Infrastructure

Founded in 1997, Cornerstone Land Surveying, Inc. has grown into one of Southern California's most dependable surveying partners for infrastructure, public works, and commercial development. As a family-owned and operated firm, we bring a level of accountability, consistency, and personal investment that larger, impersonal companies simply can't match.

Our reputation has been built one project at a time — through accurate work delivered on schedule, clear communication in the field and the office, and long-term relationships with the contractors and agencies who depend on us. Today, the majority of our work comes from repeat clients who know that when Cornerstone is on the job, the survey will be done right.

We are a licensed and insured surveying small business, and our team includes multiple licensed professional surveyors with a combined depth of experience exceeding 75 years across both capital improvement and commercial development projects.
