MDOT SHA Bay Restoration Strategies

To reduce the amount of nitrogen, phosphorus and sediment reaching the Chesapeake Bay, strategies known as Best Management Practices (BMPs) are being implemented. These strategies include structural stormwater controls, nonstructural stormwater controls, source control and land use changes. MDOT SHA right-of-way is being reviewed for possible treatment locations and the most efficient strategies are being implemented as appropriate for each site. Additionally, MDOT SHA is partnering with local jurisdictions to implement BMPs outside of MDOT SHA’s right-of-way. Please follow the links below for more information about SHA Bay restoration strategies.

Structural controls are engineered BMPs that capture and filter, infiltrate or retain stormwater runoff from roadways to reduce pollutants discharged to adjacent waterways. Learn more about MDOT SHA structural stormwater control restoration strategies.

Nonstructural controls are focused on land use management, preserving open space and protecting natural systems. See the types of nonstructural water quality improvement strategies MDOT SHA is employing.

Land use change strategies identify areas within MDOT SHA right-of-way to convert land into a more natural environment, resulting in fewer pollutants being carried off the site in runoff and reducing the pollutant loading. Explore ways SHA is changing the land use in the right-of-way to improve water quality.

Source control strategies prevent pollution at the source by removing trash, sediments and other contaminants from roadway surfaces before they wash into adjacent waterways. Find out about source control strategies implemented by MDOT SHA.
