GREEN INFRASTRUCTURE FOR CSO CONTROL IN KANSAS CITY, MISSOURI

摘要

Advanced design concepts such as Low Impact Development (LID) and Green Solutions (or upland runoff control techniques) are currently being encouraged by the U.S.EPA (EPA) as a management practice to contain and control stormwater at the lot or upland residential parcel level. These controls have shown that when implemented and maintained properly, they can increase retention at the runoff source - decreasing the runoff volume entering the drainage system and the demand on a drainage system. Both developed storm and combined sewersheds can benefit from the added storage from areas retrofitted with bioretention cells or rain gardens and other management, e.g., inlet retrofits or curb-cuts with tree plantings. This paper documents an effort by the U.S. EPA 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. This pilot project is part of a larger adaptive management approach to incorporate Green Solutions into the Kansas City long term control plan. The project involves local and regional efforts to provide the "basis-for-success" of the implementation of Green Solution infrastructure and stormwater management at the neighborhood, watershed, and regional levels. The project demonstrates the strategy and methodology, including model support, for identifying where and how Green Solutions will be implemented within Kansas City, Missouri.
