Responding to changing weather patterns

Like many other municipalities Edmonton’s weather patterns are changing and that means our drainage system, a massive network of pipes that collects rainwater, needs to change too.

A City-wide flood mitigation study has been launched to take a proactive approach to dealing with those changes.

Large study area

This study is assessing drainage infrastructure in over 160 neighbourhoods mostly built before 1989. Neighbourhoods' drainage systems were built to the standards of their day, but times and needs have changed.

Check out our latest public engagement resources to help residents be involved in this project.

 

Which communities will benefit from this study?
​Over 160 residential neighbourhoods and 33 industrial parks are being studied in this program. Engineering assessments are currently underway to assess the drainage systems in these areas and help identify potential mitigation measures.
Which improvements will be implemented?
​Potential improvements include improving overland drainage routes, constructing new stormwater management dry ponds, and building new underground storage tunnels and sewers. Where practical, other drainage improvements will be incorporated in the combined sewer service communities.
When will the program be implemented?

Due to the large scope of the project, it will likely be implemented over decades to come.

The timeframe will take into consideration project sizes and complexities, public consultation requirements, attainable workloads for the workforce, and coordination with other projects.

Where can I find more information?

​9 preliminary neighbourhood flood maps from the City-wide flood mitigation study are available for residents to review. Additional materials are also available on the public engagement page.

An additional set of maps created by the City’s consultants are also available. The information on these maps is part of an ongoing project. As such, cost estimates, engineering solutions and other data presented in these additional maps may not be current.
