Stormwater Solutions: Rain Planters

Protect Cabin John Creek, the Potomac River, and the Chesapeake Bay, while reducing your water bill!

Install a Rain Planter!


We have already allocated our 5 Free Planters in 2023 as part of our county grant.

See below for instructions on how to build your own!


Be at the cutting edge of Watershed Stewardship!
You can play a key role in preventing creek erosion and flooding
while conserving water and harvesting rain to keep your yard and garden green

Friends of Cabin John Creek has installed rain planters on properties in the Cabin John Creek Watershed through grants from the Chesapeake Bay Trust. If you install your own, you may be eligible for a rebate from the Montgomery County RainScapes program. 
What’s a Rain Planter?

  • Decorative garden container (minimum 55 gals)

  • Filled with gravel, soil, and native plants

  • Uses rainfall from the roof as irrigation

  • Connected to the roof gutter via the downspout

  • Slows stormwater down, minimizes storm system inflow

  • Improve water quality in the local waterways

Rain planters can reduce erosion by temporarily retaining rainwater and releasing it slowly over time.  Preventing erosion helps keep the Creek, the Potomac River, and the Chesapeake Bay healthier.  Rain planters can have the added benefit of directing water away from foundations and collecting rainwater for garden irrigation.   (However, do NOT use it for drinking!)
