CITY OF OTTAWA AND MUNICIPALITY OF NORTH GRENVILLE, August 21, 2017 — Members of the public are invited to an upcoming open house to review hazard maps. The Rideau Valley Conservation Authority (RVCA) has completed two hazard mapping studies for the Rideau River: Hogs Back to Kars and Kars to Burritts Rapids. These studies update existing mapping in some areas and new mapping in others. Both Rideau River studies look at identifying two main types of hazards along these stretches of the watercourse: flooding and slope stability. 

The mapping will be used by the City of Ottawa and the Municipality of North Grenville 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 RVCA’s Development, Interference with Wetlands and Alterations to Shorelines and Watercourses Regulation.

The goal of this mapping is to help ensure that sound planning decisions are made — keeping people and property safe. Accurate engineered hazard mapping is the foundation of effective floodplain and resource management.

Members of the public are encouraged to attend the open house and/or provide comments on the mapping. Conservation Authority staff welcome historical records of past flood events, 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, mapping can also be seen online at www.rvca.ca and comments sent to Ferdous Ahmed, RVCA Senior Water Resources Engineer at .

These studies are being done through a collaboration involving the City of Ottawa and the Rideau Valley, Mississippi 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. For a complete list on ongoing work, please visit www.rvca.ca.
