We're proposing a capital and operational plan to the City of Edmonton's Utility Committee, and asking for the committee's feedback on our preferred timeline and approach.
We're recommending a scenario that implements capital and operational changes over 20 years at a cost of approximately $1.6 billion in capital investment. This includes the recently approved $59 million in flood mitigation grants from the provincial and federal governments to support this plan.
In addition, we'll be recommending to the City of Edmonton a non-routine rate adjustment for 2020/2021 to fund early implementation of the SIRP strategy prior to the next formal Performance Based Rate application for 2022-2027.
Timeline for action
Major flood mitigation construction projects
Stormwater Integrated Resource Plan includes significant improvements to Edmonton's drainage system that are designed to slow and move stormwater away from high-risk areas. These projects will work in tandem with other strategies to slow, move, secure, predict, and respond to stormwater events.
- Dry ponds — green spaces that act as catch basins for excess stormwater during heavy rainfalls. We are proposing 31 dry pond sites.
- Tunnels, trunks and sewer separations — where there are combined storm and sanitary systems in high-risk areas, we will separate them, increasing the amount of stormwater we can move in extreme weather and reducing the risk of backups to nearby properties.
