Riverbank Landing

Traffic Improvements

Striving to break the link between congestion and growth, Boudreau Communities has strategically reduced overall density and sought out the balance between different commercial and residential uses for Riverbank Landing. The Traffic Impact Assessment has determined the following:

The proposed development is projected to generate between 30-50% fewer trips than as if developed with the commercial and low density residential, as the site is currently in the Area Structure Plan.

This reduces overall traffic by 424 trips per day when compared to the current Area Structure Plan.

Recommended Traffic Flow Improvements

  • Add a shared left/through lane on the north approach of the Boudreau Road/Bellerose Drive intersection and reconfigure signal timings to include split phasing on the north and south approaches to avoid interlocking left turn movements.
  • Extend the existing southbound left turn bay at the Boudreau Road/Bellerose Drive intersection to provide additional queuing space.
  • Develop a northbound right turn bay to improve existing operations of the northbound right turn movement at the Boudreau Road/Bellerose Drive intersection.
  • Improvements to the Boudreau Road/Bellerose Drive intersection, including the addition of a shared southbound left/through lane and a northbound right turn bay, are anticipated to increase capacity and improve intersection operations.
  • Boudreau Road/Bellerose Drive intersection is projected to operate under capacity with overall intersection operations of Level of Service (LOS) D based on 2034 total traffic volumes.
  • A low average delay merits a LOS A rating. Average delays greater than 80 seconds per vehicle at a signalized intersection generally produce a LOS F rating.
  • The City of St. Albert’s design threshold is LOS D for intersections, with LOS E considered acceptable for individual movements such as left turns.
