Our journey began in 1993, with a mission of serving southern California with comprehensive surveying and mapping solutions. We sought to build a reputation for providing accurate, thorough, land surveying services to our clients in a just and timely manner. We believe that doing what we say we will do, when we say we will do it, is paramount in building lasting relationships and creating a legacy we can be proud of. It’s who we are and we believe these principles guide how we treat others and how we approach our work.

Since incorporating in 2002, CNA has further strengthened our foundation by bolstering our civil engineering capabilities, increasing our flexibility, evolving our corporate identity, and expanding our resources, so we may better serve our client’s needs. We have forged a vision of becoming the name relied upon most in the Architecture, Engineering & Construction industry.

CNA strives to be at the forefront of the surveying and mapping industry, utilizing new technologies for an ancient science. Our results are attained by using progressive technology such as G.P.S., laser scanners, UAS drones and robotic methods placed in the hands of our top-notch staff. We welcome the opportunity to serve the public and private sectors of the community.

Please feel free to contact us to discuss how we can meet your needs.
