Watershed Enhancement Grant

Every year the Stormwater Management Division offers a Watershed Enhancement Grant to local non-profit 501(c)(3)organizations. The purpose of the grant is to encourage change in citizen and community behavior as they affect water quality in the Howard County's lakes, rivers and streams. 

This grant is intended to:

  1. increase citizen awareness and participation in water quality issues and projects
  2. provide education opportunities for Howard County residents and/or
  3. implement restoration projects

The Watershed Enhancement Grant is administered through the Chesapeake Bay Trust in partnership with Howard County.

Doo Your Duty

Protect Howard County parks, trails, AND waterways. Dog waste can contain multiple harmful pathogens and 1 gram can contain up to 23 million fecal bacteria. According to the EPA, pet waste is as toxic to the environment as an oil spill. 

doo your duty

Did you know? Howard County Law states owners are responsible for immediately removing pet defecation when off their own property. Violators may be issued civil citation penalties of $25-$500. Learn more and sign the pledge to doo your duty!

Landscaping with Rain Barrels and Rain Gardens

Rain barrels are a great tool to reduce stormwater pollution and conserve treated tap water. The Bureau of Environmental Services and the Howard County Master Gardeners have partnered together to provide free rain barrel workshops and giveaways to Howard County residents.

Gardening with storm water in mind will reduce rain runoff and keep pollutants from entering our streams and the Chesapeake Bay. Watch the video below to learn how you can use storm water in rain gardens, rain barrels and other environmental projects. As a Howard County resident, you can make a big impact on stormwater pollution by increasing the amount of pervious surface that absorbs stormwater runoff on your property. 

Leaves & Grass Clippings

Do not dump leaves, grass clippings or other landscaping waste into a storm drain inlet or a stream.

This is bad for water quality and is considered an illicit discharge and a violation of County Code. Discarding landscape waste into a storm drain inlet can clog pipes and lead to flooding (even in your own yard). The decaying process of yard trim can also lead to depleted oxygen levels in our stream and water bodies.
