A campus rain garden plan typically includes the layout and design of a rain garden within a school campus. Rain gardens are designed to capture and filter stormwater runoff, reducing the amount of water that enters storm drains. They often feature native plants that are well-suited to withstand wet and dry conditions, and they can include pathways, seating areas, and educational signage. The plan would show the dimensions of the garden, placement of plants, water features, and any other elements to ensure effective stormwater management and aesthetic appeal.
