Rainscaping Cost-Share Program


The purpose of this program is to improve stormwater management and benefit aquatic life in Deer Creek and its tributaries by installing landscaping that helps capture 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 these Program Focus Areas (Denny, Monsanto-Sunswept, and Pebble Creek sub-watersheds, Rock Hill and Shady Grove sub-watersheds, Hampton-Claytonia and Lower Deer Creek sub-watersheds) is eligible 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). Landowners including residential, institutional and commercial are eligible to participate.
