Rainwater Rewards

What is RainWater Rewards?

Rainwater Rewards is an online and mobile-friendly stormwater calculator that shows the value of green infrastructure investments. Green infrastructure includes stormwater management practices that allow rainwater to soak into the ground close to where it falls. The calculator was developed to help municipalities, planners, developers, and homeowners understand the investment value of green infrastructure beyond dollars and cents by looking at the value of reducing flood risk, water, and air pollution reduction, increasing property value, CO2 storage, and energy savings. This value-based approach will help make investment decisions with a complete picture of the costs and benefits associated with that investment.

The calculator was designed for small- to medium-sized cities in the Great Lakes basin, and it is versatile enough to be used by professionals and basic users alike. A property owner can enter three pieces of information describing the site and the proposed green infrastructure practice(s), to calculate an annual baseline stormwater runoff, as well as the costs and benefits of implementing that practice(s) at the block level. An advanced user, such as a municipal environmental services manager, can enter more specific information to the site and proposed green infrastructure practice(s).
