Rain garden and stormwater rebates in Maryland

6 programs in Maryland pay residents for rain gardens and stormwater projects. 5 list themselves as open now, and the median maximum is $6,000 per household. 50% ask for a plan, sketch or plant list before they approve a project.

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.
