This project focuses on the design and construction of an effective rain garden, building on the previous group's rain garden setup. It features two rain barrels, rock swales, an overflow drain, and green plant choices. The rain barrels hold 60 gallons each and will be integrated with buried piping to direct water to the garden effectively. While the rain garden promotes sustainability and aesthetic appeal, challenges include potential flooding risks and maintenance concerns. The design seeks to balance functionality with environmental impact.
