Plan and Profiles

In order to produce a plan and profile, the applicant is responsible to locate all water, sewer, raw water and storm drainage utilities within the limits of the project prior to submitting a Work in City Property/ Infrastructure Permit application. The applicant must follow the ensuing steps, in order of sequence:

1. Obtain a Utility Map of the project area.  Requests may be made in person, at 385 Kimbark Street, Longmont Co. or by e-mail to PWEng@longmontcolorado.gov
2. Apply and obtain a Work in the Right of Way Permit (for Potholing)
3. Pothole and locate the affected utilities.  This process must be made at the applicant’s expense through a private locator. In the event utilities can’t be located by the private locator, the applicant may contact City of Longmont’s Public Works for assistance.

Minimum Utility Clearances

All minimum clearances are from the closest edge of the City’s utilities to the closest edge of the applicant’s infrastructure. Minimum Required clearances are as follows:
