In 2014, the Center for Watershed Protection was asked by the Maryland Department of Natural Resources (DNR)- Parks Service (Parks) and Chesapeake and Coastal Services (CCS) to help address chronic maintenance issues associated with stormwater management on state park lands. After an initial scoping process, four projects were selected at North Point State Park and Gunpowder State Park, located in Baltimore County. The Center developed designs for the following projects and worked with DNR Parks Service, DNR CCS, and Maryland Department of the Environment to ensure that the projects addressed the park maintenance issues while providing water quality benefits:
- Permeable pavement on a 1.65-acre parking lot at North Point State Park
- Living wall terrace and rain garden at the Hammerman Beach Area of Gunpowder State Park
- Submerged gravel wetland treating 1.67 acres at the Dundee Creek Marina at Gunpowder State Park
The Center acquired all permits for the construction of the project and contracted with Stormwater Maintenance & Consulting to build the projects. To limit disruptions to park activities and visitors, construction occurred during the off season from October 2017 to May 2018. The photos below illustrate each site before and after construction was completed.

These projects were implemented as part of the State of Maryland’s commitment to reaching the Chesapeake Bay TMDL goals and EPA and interstate agreement milestones. For more information, contact Bryan Seipp at bts@cwp.org.
