The changing climate impacts the amount and distribution of rain, snow, and ice and increases the risk of floods in communities across Canada. Proper structural foundations, especially when building in flood zones, are critical in protecting homes and reducing potential damages and repair costs. The National Standard of Canada, CSA Z240.10.1:19, guides home builders and municipalities through considerations for climate adaptation related to building foundations.
 

The Standard addresses site preparation, permanent foundations, and installation of single- or multi-section buildings supported on longitudinal floor beams to improve their resistance to floods. It also provides guidance for obtaining environmental design data, including design inland flood and wave uprush levels and frost depth.
