Waterway and Stream Complaint Investigation

Capital Program and Operations
Phone: 410-887-2904
Fax: 410-887-4804

Capital Projects and Operations (CPO) responds to complaints involving erosion along County streams and coastlines. A CPO staff member will investigate the situation and will advise the property owner on corrective measures, or if the issue meets certain criteria, it will be recommended as a potential Capital Restoration Project.

Please call CPO at 410-887-2904 if you see:

  • Excessive erosion
  • Excessive aggradation (accumulation of sediment)
  • Debris in a waterway that could pose a danger to recreational boaters

Please call the appropriate agency if you see:

  • Flooding and storm drain issues – Call the Department of Public Works and Transportation and Transportation at 410-887-3720
  • Trees endangering power lines – Call Baltimore Gas and Electric at 1-800-685-1023
  • Fallen trees on County property – Call the Department of Public Works and Transportation and Transportation at 410-887-5302
  • Trash – Call your local home owners' association or watershed association to see if opportunities for stream cleanup are available

Things to Remember

  • Everything that enters the storm drain system will end up in a stream or waterway. Storm drain systems are directly linked to open waterways and do not go through a treatment process like sewer systems do. “Only rain down the drain.”
  • Streams are dynamic systems therefore minor erosion is to be expected.
  • The flow in streams will overtop the banks or flood periodically.
  • Placing yard waste (leaves and grass clippings) along stream banks degrades water quality by smothering beneficial vegetation, introducing excess nutrients and contributing to blockages.
  • Baltimore County’s policy is to allow riparian buffers (vegetation around streams and waterways) to grow naturally and not be maintained. Riparian buffers provide a host of environmental benefits such as habitat for terrestrial and aquatic species, pollutant uptake, groundwater recharge, and temperature moderation in the stream which is vital for the survival of some species.
