Heritage Drive S.E. flood barrier

Project update - July 16, 2019

Construction has begun on the  three components of this project.

A construction zone is in place near the river area adjacent to Heritage Drive. One of the two entrances from Heritage Drive will be permanently closed; the other one will remain open. There will also be a temporary alternative access to the boat launch and a temporary closure of the parking lot under Graves Bridge.

 

Impacts

There may be periodic single lane closures on Heritage Drive to facilitate construction activities.

Throughout construction, access to the river parking area will be maintained via one of the two existing access points. The easternmost smaller access off Heritage Drive underneath Graves Bridge will be permanently closed as part of this project, however, the larger westernmost access off Heritage Drive will remain unchanged.

The project team is committed to minimize any access impact to the area, and will update the project website with detour info once construction starts.

Project details

This project will ensure that Heritage Drive remains passable during Bow River flood events up to the 100-year flood. This will reduce disruption to traffic and maintain access for emergency responders. The project will also provide the last segment of a regional pathway on the west bank of the Bow River extending from downtown to south city limits.

The three components to this project include:

  • Construction of a flood barrier from the existing parking lot beneath Graves Bridge to the end of the proposed multi-use pathway that is to be constructed as part of the upgrade to the Bonnybrook Waste Water Treatment Plant. The pathway will also function as a 1:10 year flood barrier.
  • Construction of a regional pathway from the existing parking lot beneath Graves Bridge to the end of the proposed multi-use pathway that is to be constructed as part of the Bonnybrook WWTP upgrade project. The pathway will also function as a flood barrier to provide flood protection to local businesses east of Deerfoot Trail S.E. adjacent to the riverbank.
  • Bioengineering along 520 metres of riverbank (west side of Bow River) to stabilize against further erosion and loss of land and maintain the regional pathway.

Heritage Drive S.E. beneath Graves Bridge provides access between Deerfoot Trail and Glenmore Trail. It is inundated during flood events exceeding the 8-year return period flood event. During the 2013 flood, in addition to causing detours, the roadway was severely damaged by floodwaters and was impassable. A sheetpile flood barrier design (including two stoplog gates for local access roads) has been developed to protect this segment of Heritage Drive.

For the nearby riverbank from Bonnybrook Waste Water Treatment Plant (WWTP) to Graves Bridge, stability work is required to restore and preserve City lands adjacent to the river that was impacted by the 2013 flood. A pathway has also been proposed for this same riverbank area, to complete the regional pathway network between Inglewood and southern city limits (together with the proposed Bonnybrook WWTP pathway upgrades).

Once completed, this project will ensure that Heritage Drive S.E. remains passable during Bow River flood events up to the 100-year flood. This will reduce disruption to traffic and maintain access for emergency responders. The project will also provide the last segment of a regional pathway on the west bank of the Bow River extending from downtown to south city limits.

This project is an example of collaboration between three City business units (Calgary Parks, Utilities & Environmental Protection, and Transportation Infrastructure) to provide flood protection for city roadways and bank stabilization that includes restoration of riparian vegetation and aquatic improvements to improve the overall health of this portion of the Bow River.

Budget

$10.5 million
This project utilizes provincial funding through the Province’s Alberta Community Resilience Program (ACRP) and the Flood Recovery Erosion Control (FREC).

Communications

Over the past two years, the project team has worked with local businesses and landowners to provide information on project design and to receive feedback.
