Flooding Basement When it Rains
One of the first things to check is if the areaway drain outside your basement door is clogged. If drainage and waterproofing measures are in place and you are still having a significant problem, contact the Department of Environmental Resources at 301-883-5832. Staff will inspect your property to evaluate and determine the extent of the problem and if a drainage study is necessary.

This water quality practice, or bioretention concept, results in healthier lawns, enhanced landscaping and cleaner streams. For more information, please call the Environmental Services Division at (301) 883-5834 and ask for the brochure, Rain Gardens, the Natural Solution.
