Southwest Partnership Awarded $25K to Build Rain Garden on School Parking Lot, Treat Stormwater Pollution


895-sq-ft rain is a positive first step toward realizing long-term vision to improve several blocks of Carey Street in Southwest Baltimore

After an extremely competitive grant competition, the Southwest Partnership will be one of several Maryland organizations receiving an environmental restoration award from the Chesapeake Bay Trust. The partnership received notification last week of the $25,000 award, which makes it possible to build an 895-sq.-ft. rain garden on the parking lot of the Southwest Baltimore Charter School starting this spring to help treat stormwater pollution flowing from the parking lot into the Chesapeake Bay.

“A better environment is important to a better community,” said Richard Parker, president of the Southwest Partnership board. “We are excited to take the next step towards this in Southwest Baltimore.”

The rain garden will be built at the center of the school parking lot facing the west side of South Carey Street. An anticipated 20 native plants scheduled for installation in the rain garden will filter part of the stormwater that falls onto the parking lot. After filtering by the plants is complete, the excess water will flow through underground pipes to connect to the sewer storm drains. According to the partnership’s winning grant proposal, 84 pounds of stormwater will be treated annually once the rain garden is installed.

“The rain garden will greatly improve stormwater management by providing a permeable surface for a central area on the asphalt lot,” says Marilyn Powel, director of development and special projects at Southwest Baltimore Charter School.

Management of pollution from stormwater runoff into Maryland waterways has received attention by the state within the past few years. As a way for Maryland to manage water pollution, former Governor O’Malley instituted a rain tax toward the end of his term in Annapolis, requiring Maryland property owners to pay $10 to $15 per month (determined by the square footage of a house) for stormwater that runs off property. Residents can reduce their rain tax fee if they take steps to reduce the amount of stormwater leaving their properties and prove that they did so.

This project is the final phase of the school’s landscape plan that briefly lay dormant after funding for the project ran out in the fall of 2015. The Southwest Partnership, through its Safe, Vibrant, and Walkable Streets committee, stepped in and applied for the funding to keep the project moving forward.

“The committee originally planned to focus on improving the safety and walkability of the area under the B&O train trestle”, says Chris Redwood, committee chairperson. The trestle, less than half a block from the charter school parking lot, is in desperate need of attention. This past May, the committee succeeded in getting the city to turn the lights back on under the trestle. They were off for years.

Redwood, a resident of Hollins Market, adds, “When we learned that the rain garden project faced funding issues, the committee decided that this was more important than the train trestle project because of the overall benefit to the school and the health of the bay.”

Plans for the rain garden were developed by landscape architect Stephanie Tuite of Fisher, Collins, and Clark, and greenlighted by the Department of Transportation and the Department of Public Works as well as by the Baltimore City Public School System in 2015. The rain garden also received glowing support from community members. Maryland-based Parks & People Foundation will begin work to install the rain garden starting this spring.

“The rain garden will…increase the safety and viability of the S. Carey side of our campus by redirecting pedestrian traffic away from crossing the lot as an alternative to the...sidewalk,” states Powel in a letter from the Southwest Baltimore Charter School supporting the grant proposal. Safety on school grounds has been an issue in the past.

This project is only a piece of a larger effort to improve conditions along the strip of Carey Street between the neighborhoods of Pigtown and Franklin Square.
