Rain Garden

Asked November 3, 2015, 8:20 AM EST

My friend lives on low land in University Park near UMD. In the summer the mosquitoes are rampant, and in the rainy fall season sometimes the basement floods. Can a rain garden near the side of a house help prevent basement flooding and standing water on the lawn? Can you provide any beginner-level information on how to build a rain garden? We have seen plans where she would have to dig up the lawn and put pvc pipe in, is this always necessary? Thank you for your help and for taking the time to read these many questions.

Erosion/drainage can be a complicated issue to solve. You may need to have grading done to divert water from around your foundation, check your gutters and downspouts, etc. You may have to contact several sources for the best way to proceed.
Contact Soil Conservation in your County for more information and to see if rain gardens are an option. http://pgscd.org/

See the link on Rain Gardens for more information and tips. In general, rain gardens should be 10 feet away from a dwelling or foundation to prevent water from seeping into basements or crawlspaces. http://extension.umd.edu/node/2283
Master gardeners in PG County may conduct rain garden workshops in the spring and they may be able to offer some tips and more information http://extension.umd.edu/mg/find-local-mg-program
