The construction of a new flood barrier along Heritage Drive adjacent to the Graves Bridge parking lot in underway. Access to the boat ramp will not be restricted during the construction, but the parking lot may get congested with equipment. As the project get underway discussion will take place regarding truck/trailer parking allocations.
The following is the communication from the Project Manager for the City of Calgary. We will keep in touch with the City of Calgary as the project rolls out.
Bow River Trout Foundation
Construction activities have now begun on the three components to this project. They include:
- Construction of a flood barrier on the east side of the Heritage Drive / 13 Street S.E. ramp to Glenmore Trail to the 100 year flood level. The flood barrier will consist of a sheetpile wall structure with a decorative façade in the form of gabion rock cladding.
- 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 Waste WTP 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 about half-a-kilometre of riverbank (west side of Bow River) to stabilize against further erosion and loss of land and maintain the regional pathway.
Once completed—anticipated for late 2019—the constructed flood barrier will ensure that Heritage Drive S.E. remains passable during Bow River flood events up to the 100-year flood. This will help 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 impacts of this project include 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 minimizing any access impact to the area, and will update the project website with detour info when required. http://www.calgary.ca/Transportation/TI/Pages/Pedestrian-bridges/Heritage-Drive-SE-flood-barrier.aspx
