Complete Process Guide


File an Infrastructure Permit application with the City of Longmont’s Public Works & Natural Resources Department.

Permit Review & Approval

Once an Infrastructure Permit application is submitted to the City, it will be scheduled for plan review. Any comments resulting from the review process will be forwarded to the applicant for resolution. It is the applicant’s responsibility to address all comments in writing and through a revised set of plans and/or as required. An infrastructure Permit will be issued once all comments (if any) have been satisfactorily addressed. Typical estimated review time for new applications is ten (10) days. Larger projects may require additional review time.

The Infrastructure Permit review/approval does not substitute or replace any additional permits that may be required as part of this process. It is the responsibility of the Applicant to ensure that all required permits are obtained before work begins.
