Mosquito Creek Hazard Mapping Study

Project Status: Complete

OpenHouseMapMosquitoThe Rideau Valley Conservation Authority (RVCA) has completed a hazard mapping study for Mosquito Creek from Mitch Owens Road to the Rideau River in the City of Ottawa.

Much of the area has been regulated since 2017 with the completion of the report entitled: Rideau River Flood Risk Mapping from Hogs Back to Kars, July 2017. This 2017 mapping captured Mosquito Creek from the Rideau River to Limebank Road. This new study extends to Mitch Owens and will update previous mapping. 

These maps have been traditionally known as “floodplain mapping” or “regulation mapping” and they show areas that are prone to natural hazards such as flooding, erosion and natural environment features such as wetlands. 

When completed, the mapping will be used by the City of Ottawa when updating their Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. RVCA will also use the mapping to guide the review of development applications submitted under the Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation.

Members of the public are invited to share information and review the draft regulation and hazard maps (available below) during the public consultation period which will run until July 29, 2022. We also welcome you to see the draft hazard and regulations maps at the public open house.
