Rain garden and stormwater rebates
Stormwater utilities and conservation districts share the cost of projects that soak rain into the ground instead of sending it to the storm drain: rain gardens, downspout disconnection, permeable paving, bioswales and dry wells. Many ask for a site sketch and a pre-approval visit.
