Extreme Precipitation and Flooding

Projections

The CRD’s 2024 Climate Projections for the Capital Region project that there will be less precipitation in the summer months and an increased number and intensity of rainfall events in the winter months. 

Drought can harm ecosystems and challenge agriculture. Conserving water and using drought tolerant plant species are some ways to address drought at home. 

Extreme rainfall can cause major damage to both public and private property and infrastructure, contribute to erosion and ecosystem degradation, increase the likelihood of landslides, lead to road and highway closures, affect human health and safety, and disrupt everyday services and activities. The resources below share ideas for residents, and the District is also taking action, such as through Integrated Stormwater Management Plans. 

Climate Adaptation to Extreme Precipitation 

Managing Stormwater

Managing stormwater properly reduces peak flows and flooding events, making buildings and infrastructure more resilient during extreme precipitation events. We all play a role in stormwater management and there are several ways to protect your home from flooding. Visit the Flood Information for Homeowners webpage to learn what you can do to protect your property. You can also review the Home Flood Protection Checkup from the University of Waterloo Intact Centre on Climate Adaptation.

Water Conservation

Visit the CRD Water Conservation page for tips on conserving water at home and for businesses, as well as how the CRD is planning the future of our drinking water supply.  

Naturescaping

Trees, plants and soil help to absorb rain slowly, filter and break down pollutants, replenish groundwater and keep our waterways healthy. Increasing the amount of pervious surfaces on your property, including trees and natural areas, can keep your property more resilient to flooding. Naturescaping is one way to design natural areas around your property. There are many benefits to naturescaping, including using native plants, reducing the water required for maintenance and upkeep of your yard, reducing stormwater runoff, supporting healthy ecosystems and more.
