Drainage from the building and parking areas can become a unique amenity if treated properly. The best practice for stormwater runoff is to retain
water for short periods of time and allow it to soak into the ground. This is good for the environment because it reduces downstream erosion while
enhancing water quality and groundwater supplies. It also creates an attractive amenity that adds diversity and interest to the landscape. Green
infrastructure-based stormwater management practices such as bioswales and bioretention can be readily maintained and are often comparable in
cost to more conventional storm drainage infrastructure. Drainage structures should be planted with native grasses and perennials and reinforced with
river stones. Proper landscaping will allow the basins to become attractive garden features, and also provide habitat for frogs, salamanders, and
pollinators. It can serve as relaxing scenery, an opportunity for nature play, and an educational element for visitors to learn about water and ecology.
