RiverSmart Maintenance Assistance Program

The RiverSmart Maintenance Assistance Program (RSMAP) assists property owners with the maintenance of their installed RiverSmart rain gardens and BayScapes.  The program offers homeowners two types of maintenance assistance including (1) free do-it-yourself advice from the RSMAP team or (2) direct maintenance work through a referral network of contractors.  Work provided by referred contractors is subject to availability and standard rates.

See Maintenance Assistance Options below for service and pricing details.

The RSMAP is a program of the Alliance for the Chesapeake Bay, delivered in partnership with Urban Ecosystem Restorations (UER), a nonprofit urban land trust devoted to the development and preservation of Eco-Functioning Spaces (value-enhancing urban green spaces that perform ecological functions). The RSMAP is supported through grant funding provided by the District Department of Energy & Environment (DOEE).

“My rain garden was installed in May 2014 and is in need of some minor maintenance. The berms of the rain garden have eroded and the interior of the garden had filled with leaf and other debris, reducing its capacity to retain water. The overflow pipe from the rain barrel and the sump in the rain garden were in good shape. The BayScaping is fine – just needed some sprucing up. I elected to use the Level 3 Maintenance Services and was happy with the results.”
- Stephen R., Homeowner, Ward 5
