Storm Drainage Maintenance Frequently Asked Questions

  • The storm drain inlet in front of my house is clogged. Who do I contact to clean it out?

    Residents may report clogged or blocked storm drains to the Office of Highway Maintenance's Customer Service Office on (301) 499-8523.

  • The stormwater management facility (pond) behind my house is full of trash and debris. Who is responsible for maintenance of the facility?

    Residents may contact the Office of Highway Maintenance's (OHM) Customer Service Office at (301) 499-8523 to find out if the County is responsible for maintenance of the facility. The OHM performs functional maintenance on its facilities (such as mowing and clearing obstructions to the flow of water) once per year.

  • The stream behind my house is blocked with tree limbs and debris. Who is responsible for cleaning the stream?

    If the stream is located on private property, the property owner would be responsible for the removal of the debris. The Maryland National Capital Park and Planning Commission is responsible for maintenance of streams located on park property. The Department of Public Works and Transportation's Office of Highway Maintenance (OHM) will remove blockages from County maintained storm drainage channels. You may call the OHM's Customer Service Office on (301) 499-8523 to seek assistance in determining maintenance responsibilities for streams and storm drainage channels.

  • Sinkholes have formed in my yard. Who is responsible for filling them?

    The Washington Suburban Sanitary Commission (WSSC) can determine if there are sewer or water lines in the vicinity of the sinkholes. If a public storm drain is located in the area, the County can determine if the sinkholes are caused by the storm drain. If the sinkholes are unrelated to WSSC or County lines, it is the property owner's responsibility to find out the cause and make corrections. If an abandoned well or septic system is suspected or discovered, please contact the Prince George's County Health Department for further information.

  • The small drain near my basement door is blocked and causing my house to flood. What can be done?

    This is an areaway drain and is the responsibility of the property owner to maintain it. The resident should check to see if the small grate on top of the drain is clogged and clear it if necessary. If the grate is clear, a plumber should be contacted to ensure that the pipe leading from the areaway drain is clear and free of obstructions.

  • The opening to the storm drain in front of my house appears to be large enough for a child to go through. Who is responsible for fixing this?

    The County allows this opening to be no more than 7 inches in height. The Department of Public Works and Transportation Office of Highway Maintenance (OHM) can determine if the opening is too large and take any corrective action needed. You may contact the OHM's Customer Service Office at (301) 499-8523 to arrange for an inspection of the storm drain.
