Guidelines and Requirements for Range Points

 Range Points are the survey monumentation used to permanently establish & preserve the public rights-of-way of in the City and County of Denver. 

This practice has been in effect in the City and County of Denver since the late 1800s. Ordinance 41 Series 1886 requires  “stones not less than two feet long and four inches square, properly marked, or iron bolts not less than two and one-half feet long, and one and one-half inches in, set or driven one foot below the established grades of the streets at all points of intersections of range lines; said range lines to be run approximately twenty feet from the northerly and westerly sides of each street”. Many of these original monuments are still being used to reestablish the rights-of-way of existing streets.

The City and County of Denver Surveyors are striving to recover, preserve, and perpetuate local control that is based on our historic City records in a manner consistent with the care and professionalism of our predecessors that originally established the control system. 

Today, establishment or reestablishment of Range Points is a requirement of the development approval process by the PUD/PBG Site Plan Rules & Regulations page 29 and the Subdivision Rules Regulations page 31.
