Apply for a RainScapes Rebate

Illustration of a person gardening near a house with flowers, greenery, and rain; the word "RAINSCAPES" appears at the bottom.

Rainfall that lands on conventional lawns, roofs, patios, walkways, and driveways rapidly accumulates into runoff and collects pollutants like pet waste, fertilizers, pesticides, car fluids, and trash before entering storm drains and being carried to local streams and the Chesapeake Bay. Runoff not only impacts the health of our local waterways, but can cause drainage issues around your home or yard, and increase the chances of flooding for your downstream neighbors. Learn more by reading the Homeowner’s Guide to Sustainable Home Drainage.

Residents can play an important role in reducing pollution and flooding, and creating wildlife habitat by installing small-scale stormwater projects through the RainScapes Rebate Program.

How to Apply

Eligible properties in the City of Rockville, including single-family and townhome residences, homeowners associations, condominium associations, religious institutions, private schools, and other nonprofits can receive up to a lifetime maximum of $5,000 in rebates.

Rockville is proud to partner with the Chesapeake Bay Trust for the RainScapes Rebate Program. The trust will review and process applications, perform site visits, and is available for questions.
