Excavation permit

An excavation permit is required to break the surface of a city road right-of-way such as, a street, a sidewalk, or a boulevard. 

The permit is required when a private company or utility excavates on The City of Calgary property as per Streets bylaw 20M88. The excavation permit authorizes the utility or contractor to complete the intended work. 

Only indemnified contractors can obtain an excavation permit, however builders / developers with residential excavations where all cuts at a single site are equal to or less than 100 m2 may obtain a permission to permit number from the Roads excavation permit office. This number should be provided to all indemnified contractors working on a developers property so the degradation and surface restoration fees are not charged to each contractor as the builder / developer has already paid them. 

See the frequently asked questions regarding excavation permits.

Builders with excavations smaller than 100 m2 should contact the Roads permit office at 403-268-4936 for information on a Permission to Permit or a Roads indemnified contract.

Application deadlines


The permit office requires a minimum of 48 hours (two business days) prior notice to issue a permit. However, if the dig is an emergency dig and the excavation permit office is closed, then the utility/contractor can go ahead with the emergency work. Then, apply for the excavation permit the next business day.




A permit must be obtained prior to starting the excavation. The permit is valid for up to 14 days. This is usually dictated by the expected start date in which the contractor or utility will need to provide with the excavations permit application.


There are exceptions when a permit is valid longer than 14-day period. For instance, if there is a tender, an indemnification agreement, addendum or other contract with the completion date on it, the permit is valid for either 6 months, or the end of the current calendar year or the date provided on the agreement.


Permit costs


Pavement Degradation Fee


All utility cuts reduce the life of a road and require more maintenance costs. The pavement degradation fee is meant to cover the additional costs incurred due to utility cuts in the road. This fee will apply to all cuts into an asphalt road. An extensive independent engineering study was conducted and the results showed that all cuts reduce the life of a road by 22 per cent which result in additional costs to The City to repair and maintain the road. The consultant used a standard method that has been used by other cities to calculate the permit degradation fee for the City Of Calgary.


How the fee is calculated


The degradation fee calculation including the zone of influence was calculated in a similar method as used by other cities across North America and is:

Pavement Degradation Fee = (% Serviceability Loss X Reconstruction Cost) + (Additional Maintenance Cost)

Fee = ((W+2)x(L+2))x(rate for road class Arterial $49, Collector $44, Local $40)

This fee applies to all excavation permits that cut an asphalt road and is determined by the individual cut size, road classification and rating prior to the excavation.

Surface restoration fee


The surface restoration fee is different from the degradation fee and applies to roads with a VCI (visual condition index) of seven or more as these roads are considered to be in good condition. Please see the map to determine which roads have a VCI of 7 or more. The fee is $49/m2 however a Roads paving technician must evaluate the area that must be milled and paved to restore the driving surface back to the high quality it was prior to the cut. There is a minimum width and length to accommodate the milling and paver equipment, as well as the location of the cut can affect the area required to restore the surface of the roadway.
