Stevens Creek Hazard Mapping Study

Project Status: Active

Web update: May 5, 2022

The Rideau Valley Conservation Authority (RVCA) has completed a hazard mapping study for Stevens Creek from Malakoff Road to the Rideau River in the City of Ottawa.

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.

Public consultation on the draft hazard mapping study for Stevens Creek from Malakoff Road to the Rideau River will continue until April 29, 2022. Virtual public consultation began late November 2021. Affected landowners were notified by mail and staff have been responding to inquiries by telephone calls, e-mail, virtual meetings, small group in-person meetings and site visits. In some cases the draft mapping has been refined based on site-specific information.

With the recent easing of provincial COVID-19 restrictions, the RVCA is now able to host an in-person presentation and question and answer session to provide an additional opportunity for public consultation.
