Contain the Rain Program

Create a sustainable landscape in your yard! 

The Contain the Rain Program supports residents who want to reduce rain and snow runoff. Water from rain and melting snow that enters storm drains collects pollutants as it find its way to our streams, rivers, and lakes. Planting native plants and trees reduces the amount of stormwater going into storm drains. They also support the natural ecosystem and provide food for pollinators like bees and butterflies. 

We’ve partnered with the Johnson County to give up to $2,225 to residents to help offset material and labor costs.

The City reimburses the following:

  • Rain Garden: 50% match up to $1,000
  • Rain Barrel: 50% match up to $75
  • Native Tree Plantings: 50% match up to $150
  • Native Plantings: 50% match up to $1,000

Frequently Asked Questions

What is stormwater?

Stormwater runoff is the water generated when rain, snow melt, and surface drainage flows over streets, parking lots, sidewalks, and rooftops. The stormwater doesn't absorb into the ground.

Where does stormwater go?

As stormwater runoff flows over land and hard surfaces, it picks up sediment, contaminants, litter, nutrients, and other pollutants, which then discharge into the waterways, untreated. Unmanaged stormwater affects Merriam's waterways by causing water pollution, streambank erosion, and flooding issues.

What can I do to help reduce stormwater runoff?

You can capture rain water where it lands and slow down the stormwater through stormwater treatment facilities (STFs). The pollutants and sediment have a chance to settle out rather than go into Merriam's waterways. These STFs include rain barrels, rain gardens, native trees, and other native plantings. These facilities can help improve the quality of water that flows to creeks, streams, and into our rivers.
