Storm Drain Marking Program

Help protect our County’s waterways from pollution by organizing your class, scout group, family, and neighbors to place storm drain markers in your neighborhood.

As rainwater and melting snow wash over our lawns and gardens, sidewalks, and streets, it picks up pollutants and trash that end up in our storm drains. This stormwater flows directly to the County's waterways without being treated at a wastewater treatment plant. This untreated stormwater – and pollutants it carries such as pet waste, fertilizer, household chemicals, antifreeze, and gasoline – pollutes our waterways, creating an unsafe environment for people, pets, and wildlife.

The storm drain marking program allows the community to work together to protect our waterways. Volunteers apply educational messages on storm drains to remind residents that whatever goes into storm drains travels untreated to our creeks, streams, and rivers.

Request a Storm Drain Marking Kit:

  1. Estimate the number of storm drains you plan to mark. 
  2. Walk around the area where you would like to work and count the number of storm drains that you want to mark. 
  3. Recruit a group of people to help. Explain that the activity will only take a few hours and that it will help prevent pollution of our waterways.
  4. Email our Outreach Coordinator, Sally Albright at or 410-222-0136 to request a storm drain marking kit!
