Airdrie has hundreds of kilometres of sidewalk, and this number is growing with every new subdivision constructed. Engineering Services reviews sidewalk plans to provide residents with a safe and economical means of transportation.
In new developments sidewalks are maintained by developers until the City takes over ownership. During Final Acceptance Clearance (FAC) inspections, sidewalks are held to City design standards and replaced or repaired as necessary. After FAC approval, sidewalk repair and maintenance is done during local improvements or as part of the Public Works annual concrete replacement program.
Engineering Services reviews street plans for all new subdivisions within the city to ensure current and future commuter needs are met.
Developers are responsible for monitoring and keeping the streets clean until the City takes over ownership. Once approval has been received, Public Works is responsible for maintaining city streets. Public Works has an annual spring cleaning program and will further monitor roadways and clean on an as-needed basis.

The CP Rail underpass located east of 8 Street and north of Yankee Valley Boulevard links Luxstone Landing with Nose Creek Park.
The existing structure was originally constructed in 2004 as a box culvert designed to convey water flow from the Canals stormwater facility.
A pathway was added in 2007 to utilize the structure as a pedestrian underpass during low flow periods.
Due to past high flows and ice issues, the underpass has often been temporarily closed to the public, causing frustration among residents and creating safety concerns.
It is clear a year-round, pedestrian-specific solution is required.
Engineering Services, in consultation with Infrastructure Systems Limited (ISL), assessed four options to provide an increased level of service at the pedestrian crossing.
- Option 1 - New precast concrete box culvert (underpass) installed by open cut approximately five to 10 meters south of the existing culverts. The location improves alignment with the existing pathway and provides a crossing for exclusive pedestrian use, with no hydraulic function. The estimated cost for this option is $750K. One risk with this option is that the City may be subject to substantial costs for loss of operating revenue during a track closure, if it is permitted.
- Option 2 - New precast concrete box culvert (underpass) installed by tunnelling. This is similar to option 1 but uses tunnelling as an alternative installation method. The estimated cost is $2 Million. This option would not run the risk of costs associated with a track closure but the City may be subject to substantial costs to mitigate potential track settlement and CPR may not allow tunnelling due to potential risk of track settlement.
- Option 3 - Overpass structure. The optimum location for a bridge over the tracks would be about 200 meters south of the existing tunnel where there is relative open space on both sides. This location also allows for a variety of possible options for construction of approach ramps on either side of the crossing. The estimated cost is $3 Million and this option comes with nominal risks.
- Option 4 - At-grade level crossing. This option would involve constructing a minimal length of new pathway to tie into the existing pathway network. This crossing would be located approximately 5 to 10 meters south of the existing drainage culverts. The construction of a new at-grade crossing would include bells, gates (arms or offset gates) and flashers. The estimated cost for this option is $500K. The risk associated is CPR may not allow an additional at-grade crossing due to safety issues.
Further details on the options being considered are available in the report to Council.
Staff will begin consultation with Canadian Pacific Railway regarding right of way, safety and other design considerations to determine whether any of the options would be deemed feasible.
Given that one or several of the options are acceptable to CPR, staff will return to discuss the go-forward plan at a Council meeting.
