Flood Risk/Hazard Mapping Reports

Contact Ferdous Ahmed, Senior Water Resources Engineer

In cooperation with local municipalities and the province, the RVCA identifies, studies and maps natural hazard areas along local rivers, lakes, streams and wetlands. Natural hazard areas include floodplains, unstable slopes. Natural features such as wetlands are also mapped. In the past, these maps were called flood risk maps.

If not understood or dealt with effectively, these hazards can pose risks and problems to society, especially when considering development activities.

Hazard mapping is used by watershed municipalities when updating Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. The RVCA uses the mapping for the administration and enforcement of regulations made under the Conservation Authorities Act (Section 28).

Current Studies

RVCA is currently working on several hazard mapping studies. Ongoing work includes:

Bilberry Creek* (Innes Road to Ottawa River) — click for details
Stevens Creek* (North Gower)
Monahan Drain* (Kanata South)
Mosquito Creek* (Riverside South)
Upper Jock River Hazard Land Mapping Study (Beckwith Township)
Middle Rideau River (from Burritt’s Rapids to Smiths Falls), a small portion of this study area is in the City of Ottawa (between Burritt’s Rapids and the Montague Township boundary on the north side of the river)
Wolfe/Sand Lake System

*These studies are being done through a collaboration — known as the City of Ottawa Hazard Mapping Project involving the City of Ottawa and local conservation authorities.

Public Input

The RVCA welcomes input from local residents. Every bit of information that we can obtain about the historical behaviour of these areas can be very useful for evaluating the "reasonableness" of the flood lines shown on the maps. The study team is happy to review any past flood information that people wish to share including anecdotal or documented information such as photographs or journal entries of their observations during past high water events.

This information can be shared at any time or at future public open house scheduled for the individual hazard mapping studies. Watch for notices or opt-in to our media release distribution list. Information can be shared with Ferdous Ahmed at 613-692-3571 ext. 1170.
