Description:
The NRMRL is conducting this project to evaluate the water quality and quantity benefits of a large-scale application of green infrastructure (low-impact development/best management practices) retrofits in an entire subcatchment. It will document ORD's effort to demonstrate the efficacy of implementing integrated green infrastructure-based solutions to support control of wet-weather flow pollution problems in an urban core neighborhood within a combined sewer system. These green infrastructure controls have shown that, when implemented properly, retention at the runoff source can increase -- decreasing runoff volume entering the drainage system and the demand on the drainage system. Both developed stormwater and combined sewer watersheds can benefit from the added storage from areas retrofitted with bioretention and infiltration cells or rain gardens and other management techniques such as inlet retrofits and curb-cuts. This pilot project is part of a larger adaptive management approach to incorporate Green Solutions into the Kansas City, Missouri Combined Sewer Overflow Long-term Control Plan. The project will demonstrate the methodology, including model support, for identifying where and how Green Solutions will be implemented in Kansas City.
