Flooding in Basement

Wet basements are routinely a result of inadequate below grade water proofing, non functional French drains, sump pump failures and the lack of grading the ground sloping away from the house. Residents may wish to contact a plumber and/or housing contractor since this is rarely a Department of Transportation storm drain issue. Most storm drains are located in the street, away from the house.

If the road is a numbered route such as Rte. 355, 117, please contact Maryland State Highway at 301.513.7300 OR 410.582.5650 (out of normal business hours). The Operations Center is 800.543.2515.

To speak with a Customer Service Representative, please call 311 during business hours.
