Dennis Avenue Green Streets
As a part of the County's effort to protect our waters, the Department of Environmental Protection (MCDEP) and Department of Transportation (MCDOT) are collaborating on a Green Streets project in the Dennis Avenue area. Green Streets projects generally involve installing small-scale stormwater practices within the County's right-of-way to capture water from roadways and sidewalks during storms.
Various public events will be held through out the project phases for residents to learn about the project and to provide input on the design of the project.
