The increasing risk of flood damage to Canadian homes is expected to be reflected in changes to the National Building Code of Canada.
The CBC reports that the National Research Council (NRC) is working with a Maryland-based firm which has expertise in flood-proofing buildings, on how to better protect against the risk that is predicted to grow in both frequency and severity.
The report says that the implementation of building codes is a provincial matter and while six provinces use the national code without amendment, Alberta, British Columbia, Ontario and Quebec have included some variations.
Although experts from Coulbourne Consulting helped define the US building code relating to flood-resistant buildings, they say that the Canadian code will be bespoke.
For example, flood plan building in the US prohibits basements, but deeper foundations in Canadian buildings would make this difficult. But it may mean Canadian homeowners in flood-risk areas being ready to use their basement as a place to collect water when flooded.
The CBC report says that the consultants are there to advise the NRC rather than telling them what the code should be.
