Bilberry Creek Hazard Mapping Study

The Rideau Valley Conservation Authority, in collaboration with the City of Ottawa, has recently embarked on a hazard mapping project along Bilberry Creek from Innes Road to the Ottawa River. Hazard mapping for Bilberry Creek looks to identify flood risk and slope stability hazards.

The RVCA has identified flood risk hazards in the area. Results will be available at an upcoming public open house. The flood risk maps identify areas along watercourses that are vulnerable to flooding and where new development is to be restricted or prohibited in accordance with provincial and municipal planning policies.

As much of the Bilberry Creek Area is already developed, properties in the regulated area would require project review and approval prior to any construction projects (new buildings (sheds, garages), additions, swimming pools, etc.) from the Conservation Authority (Ontario Regulation 174/06, Development, Interference with Wetlands and Alterations to Shorelines and Watercourses). The mapping will also 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

Identifying flood risk is step one of the hazard mapping process. Additional work is underway by the Conservation Authority and City of Ottawa to better understand slope stability and erosion along Bilberry Creek.

This public open house offers the opportunity for RVCA staff to respond to any questions that you may have regarding the mapping and collect your input about local conditions. For further details in advance of the open house, please see the enclosed factsheet.

Members of the public are encouraged to attend the open house (details below) and/or provide comments on the mapping below. Conservation Authority staff welcome historical records of past flood events, slope failure, erosion, news clippings, photographs and even anecdotal stories to help confirm the reasonableness of calculations and resulting hazard mapping. For those unable to attend the open house, comments can be sent to Ferdous Ahmed, RVCA Senior Water Resources Engineer at .

These mapping studies are being completed as part of the City of Ottawa Hazard Mapping Project.

These studies are being done through a collaboration — known as the City of Ottawa Hazard Mapping Project — involving the City of Ottawa and the Mississippi Valley, Rideau Valley and South Nation Conservation Authorities. The City recognized a need to update its zoning schedules based on up-to-date flood risk mapping and has provided contributions enabling the Conservation Authorities to move ahead with these studies sooner than would otherwise be possible. The RVCA is currently working on several studies in the Ottawa area.
