Welcome to the PLSC Website!

We encourage land surveying professionals and individuals interested in our profession to participate in our upcoming events, visit our Chapter websites and get involved! This is a great profession, and PLSC is here to support the profession to continually improve the practice within Colorado.

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.

Dedication for the Replacement Bronze Donor Plaque at the 6PM Initial Point
Posted July 09, 2019

The dedication for the replacement bronze donor plaque at the 6PM Initial Point was held on June 22. Surveyors in attendance represented three of the five 6PM states. Including a group of interested people, there were around 25 people at one time who came to the site. The forecast of rain along with uncertain road conditions prevented many others from attending. When the manhole lid was removed, nearly the entire hole containing the stone and brass disk was full of water which had to be bailed out. The concrete pad surrounding the monument was cleaned off and the cracks were sealed. Concrete joints in the areas around the donor plaque and obelisk were also sealed. Attention was given to the 1935 triangulation station and its associated marks since they had been neglected (See attached pdf). Those attending discussed the future needs at the site which will be made known when cost estimates are secured.

Provide your feedback on State Plane Coordinate System
Posted May 31, 2019

Colorado provide your feedback on State Plane Coordinate System Options for Colorado before it's too late. The deadline to submit feedback to the Colorado Geodetic Working Group is August 31, 2019. If you work in Survey or geospatial, we want to hear from you. We encourage all to participate; even if you have provided feedback to us in the past. This will be the final outreach opportunity to submit feedback on what YOU want the Colorado State Plane Coordinate System to look like for 2022 before Colorado submits their plan to the National Geodetic Survey. Please share the link to participate in the survey to those that may not otherwise see this posting. You do not need to be a PLS to participate. If you are unfamiliar with the State Plane Options, please review the article in the May 2019 edition of Side Shots titled "2022 Colorado State Plane Coordinate System" on pg. 19.
