RainReady Homes

What is the RainReady Homes Program?

The RainReady Homes Program is part of Cook County's broader RainReady initiative. It funds home improvements to help prevent basement sewer backups for Riverdale residents. The improvements include features that capture or redirect stormwater, like overhead sewers and green infrastructure.

Program Highlights:

  • Goals: The initiative aims to reduce basement sewage backups, flood risk, improve public health, promote environmental sustainability and improve overall quality of life in participating communities.
  • Eligibility: Funding is available to a limited number of homeowners in Riverdale who experience basement sewer backups and meet specific property criteria. 
  • Cost: Project management, home assessment and all eligible improvements including overhead sewers, rain gardens and rain barrels are provided at no cost to participating homeowners. 
  • Implementation: The program includes a full range of services from home assessments and design consultations to construction and maintenance of the installed features through 2026. 

How to Get Involved: Interested Riverdale homeowners can apply by filling out the program’s interest form.
