This report examined efforts to manage combined sewage overflows and create effective stormwater management plans. To provide background on the issue, a brief history of sewage management was provided, along with the legal history regarding water quality, sewage and CSOs, effects of CSOs and current green infrastructure methods for dealing with CSOs. The report then compared the efforts of three cities--Portland, Oregon; Philadelphia, PA; and Chicago, IL--to improve water quality and manage CSOs and stormwater. From the examination of the efforts of these cities the author derived a list of ten recommended elements for a CSO/stormwater management plan. These recommended elements were then used to evaluate New York City's recently released sustainable stormwater management plan and its prospects for success. / text
