Need a Land Surveyor?

PLSC cannot recommend one surveyor over another. If you need a land surveyor, please  go to the Colorado Department of Regulatory Agencies (DORA) and download the list of Colorado licensed surveyors and also check for any disciplinary actions against a particular surveyor under the "Verify License Tab" on the DORA site. Certified Federal Surveyors are listed at Be sure to check references for the surveyor you are considering hiring.
