Rosemont Drainage Improvement Project

About the project

In the past, heavy rainstorms have flooded homes and nearby roadways in the community of Rosemont. These issues have been all over the community, and range from overland flooding to basement sewage backups.

Our recent drainage studies found that the old system, built in the 1950s to standards of the day, could not handle the water it received during large rainfalls.

To reduce flooding before it enters Confederation Creek, we started the Rosemont Community Drainage Improvement Project. This project will make changes so the storm drainage system will be able to handle peak water flows for one-in-50-year rain events.

Please see thelatest project update for more information on the flood prevention tools put in place and on traffic controls used to increase safety in the neighbourhood.
