Flood Risk/Hazard Mapping Reports
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).
RVCA is currently working on several hazard mapping studies. 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. Ongoing work includes:
- Bilberry Creek (Innes Road to Ottawa River) — ongoing
- Stevens Creek (North Gower)
- Monahan Drain (Kanata South)
- Mosquito Creek (Riverside South)
- Mud Creek (Prince of Wales Drive to Rideau River) — ongoing
- Becketts Creek (Sarsfield Road to Ottawa River) — 2019
- Flowing Creek (Flewellyn Road to Jock River) — 2018
- Hobbs Drain (Fallowfield Road to Jock River) — 2018
- Kings Creek (Brunton Side Road to Jock River) — 2017
- Nichols Creek (Montague Boundary Road to Jock River) —2018
- Rideau River (Hogs Back to Kars) — 2017
- Rideau River (Kars to Burritts Rapids) — 2017
