Partner with PHG
By partnering with Patapsco Heritage Greenway (PHG), you are supporting the conservation and protection of the Patapsco Valley. And there are plenty of ways to get involved! From stream cleanups to locating invasive plants (and removing them), everyone can do their part, whether through individual initiative or an organizational partnership.
Group Programs
Patapsco Heritage Greenway offers Group Programs that provide opportunities to actively contribute to the preservation of the Patapsco watershed while fostering stronger relationships among team members, the local community, and the environment. Whether your group is from a corporate office, grassroots organization, congregation, scout troop, or other entity, we offer opportunities for and welcome everyone. Stewardship experiences with Patapsco Heritage Greenway include an environmental stewardship event along with the opportunity to include a post-event social at a local small business.

Annual Local Business Sponsorships
We invite local businesses and organizations that share our goal of preserving, protecting, interpreting and restoring the Patapsco River Valley to become annual sponsors. Sponsorships help support PHG’s free public programs, including lectures, stream clean-ups, invasive plant removals, environmental education workshops and tree plantings. These events attract local residents and visitors, giving sponsors the opportunity to connect directly with PHG’s extensive network of volunteers and participants.

Collaborative Projects
Bull Branch Watershed Assessment

A one-year pilot project aimed at assessing the reaches of the Bull Branch most in need of restoration, improvement, retrofits or other stormwater management solutions. Project facets include a Stormwater Management/BMP Assessment, Stream Assessment, and Forest Characterization.
Scope of project
The stream will be assessed from its headwaters in downtown Catonsville to its output into Soapstone Branch, which feeds into the Patapsco River. All Bull Branch stream corridors will be walked, potential issues inventoried, and all stormwater assessed and modeled for proper drainage. The upland forest areas will also be inventoried for mature specimen trees.
PROJECT TEAM
- Environmental Systems Analysis, Inc. (ESA) and Gannett Fleming are the contractors performing the natural resources and stormwater assessment
- Maryland Department of Natural Resources (DNR) is the funding source of the project and can provide additional technical expertise and resources
- Restoring Bull Branch (RBB) is the community group who identified the issue and sought to initiate a plan for improvement
- Patapsco Heritage Greenway (PHG) is the 501c3 nonprofit overseeing the grant execution and serves as the liaison between team members and stakeholders

Defensores de la Cuenca (DDLC) and Patapsco Heritage Greenway (PHG) are working collaboratively to advance the mutual goals of PHG and DDLC of engaging the Latino communities of Howard and Baltimore counties around conservation and stewardship in and around the Patapsco River watershed. We are creating shared experiences for fun, family friendly activities to teach about watershed stewardship, outdoor recreation and our connection to the river in a safe and comfortable way. This included a series of four events in FY22 and early FY23 and will continue into CY2023.
