Rainscaping Cost-Share Program


The purpose of this program is to improve water quality and benefit aquatic life in Deer Creek and its tributaries by installing landscaping that helps manage stormwater by capturing rain where it falls, instead of allowing water to run off-site.

Rainscaping is any combination of plantings, water features, catch basins, permeable pavement, and other activities that manage stormwater as close as possible to where it falls, rather than moving it someplace else. Rainscaping can also be employed to solve a drainage problem, increase aesthetic appeal, improve property values, and/or attract birds and butterflies, in addition to other benefits. Rainscaping practices can include features such as rain gardens, bioswales, trees and shrubs, green roofs, etc. to slow down, soak up and reuse rainwater before it carries pollutants to a local stream.

Each landowner with property located in one of the Program Focus Areas is eligible to apply to receive a rebate of 75% of approved and documented costs up to a maximum of $4,500 for project design, implementation, and/or maintenance costs incurred for Rainscaping Cost-Share funded feature(s). NEW in 2023, institutional applicants are eligible for a rebate of 60% of approved and documented costs up to a maximum of $6,000. 

Verify your eligibility with this NEW interactive map! Enter your address to see if you are located within one of the Program Focus Areas.  Note, these areas are shaded purple within the purple Deer Creek Watershed boundary. Landowners including residential, institutional and commercial are eligible to participate. If your address is not located within one of the Deer Creek Watershed Program Focus Areas, you may qualify for the MSD Rainscaping Small Grants Program instead. There is some overlap in the Deer Creek and MSD program areas, and you may qualify for both programs.  Landowners may only receive ONE award from ONE of these rainscaping programs.  Landowners may not receive multiple awards from one program or an award from both programs.

You are required to complete an orientation for landowners (if you haven't previously attended one within the past two years) to learn more about the Rainscaping Cost-Share Program if you would like to apply. All live orientations have passed for 2024. You can still fulfill your orientation requirement by watching the orientation recording and completing the accompanying survey.
