Storm Drain Information
The Bureau of Highways is responsible for unclogging storms drains within the County right-of-way.  As the leaves fall, Howard County’s Department of Public Works is asking residents for help in keeping our storm drains clear of debris. This will not only help in preventing clogs, it will also aid in protecting local waterways.

“Residents can help protect their property and the Chesapeake Bay by keeping leaves and other yard debris out of our roadways,” said Jim Irvin, Director of the Department of Public Works. “They can clog a storm drain.

  • Mulch your leaves with your mower; they can help nourish your lawn.
  • Mix your leaves with grass clippings and vegetable refuse to make compost. To learn more about backyard composting, visit the County Composting page.
  • Participate in the Rake-and-Take program where “rakers” (residents who rake and bag leaves and grass) are matched with “takers” (people who want leaves and grass for composting). For more information about this program, visit
  • When rain is in the forecast, check nearby storm drain grates and clear them of debris.
