The National Weather Service has declared March 9-13 Flood Safety Awareness Week in Illinois.
While flooding is a natural occurrence, continued urbanization and climate change increase the amount of flooding we experience. Increased stormwater runoff can overwhelm sewers and lead to urban flooding, such as ponding water in streets and yards, basement seepage, and sewer backups. Stormwater eventually flows to rivers and streams and can cause more flooding as water flows over riverbanks and into the floodplain.
This week, senior planners Nora Beck and Kate Evasic presented at the Illinois Association for Floodplain and Stormwater Management conference. They talked about our Regional Flood Susceptibility Index as well as Midlothian's new stormwater management capital plan, one of our Local Technical Assistance projects.
ON TO 2050 recommends reducing flood risk through actions like identifying risks and improving planning and development to reduce current and future risk. Additionally, CMAP has developed the Regional Flood Susceptibility Index to identify priority areas across the region for flood mitigation activities. The index is used to integrate stormwater management strategies into our Local Technical Assistance projects. Read our Guide to Flood Susceptibility and Stormwater Planning for more information on how to use the flood susceptibility index in planning activities.
