Instructions Application

PLEASE NOTE: The Engineering & Development Services Division’s Encroachment permitting software has transitioned, as of May 1, 2023, to the new program Enterprise Permitting & Licensing (EPL).

Unfortunately, due to unforeseen circumstances specifically with the Encroachment Permit portion of the new program, the Civic Access Portal for online applications is not available for Encroachment Permits, at this time.

While we continue to work on the programming issues, please continue to apply using the Encroachment-Permit-Application-Instructions document. You may find that PDF document by clicking the link above labeled Encroachment Permits: Instructions Application.

The Instructions are the first two pages and they include the email address where you can submit your EP application package for review. Please make sure to include the required items to avoid delays in the review/processing timeframe.

Please click here to read more about our new online permit application system coming soon for Encroachment Permit Processing with EPL & the Civic Access Portal.
