The Program is divided into two groups: major projects and sewer separation projects. Project implementation was selected based on its positive effect on water quality, supporting development, its priority in the construction sequence, and cost. The schedules were further coordinated to allow for concurrent construction. A list of projects by LTCP phase is located in the Appendix.

CURRENT CSO PERMIT IS VALID THROUGH OCTOBER 2020 The CSO permit was approved by NDEQ in September 2015 with refined requirements that lower the City’s costs and in support of Omaha’s Program. The next required CSO permit renewal is October 2020.

Adams Park Wetlands Improvement Project This project consists of wetlands designed to reduce Combined Sewer Overflow (CSO) volumes, sewer backups, improve water quality, and provide a neighborhood amenity. The existing combined sewer will be converted into a sanitary sewer that will provide sewer separation for the sub-basin. The new storm sewers will drain into a new wetland area in Adams Park. The Adams Park wetlands and detention area is designed to provide the maximum practical stormwater storage to reduce the size of future downstream facilities. The wetlands consist of an area covering approximately 14 acres, separated by the park road. A low dam with an emergency spillway is complete on the north side of the park, near Bedford Avenue, to provide detention volume of up to 77 acre- feet, which will detain the 100-year storm event. The wetland facility is designed to provide water quality Adams Park outfall structure and wetlands near 36th and Bedford. benefits and beautification elements. www.OmahaCSO.com Clean Solutions for Omaha Quarterly Report | 2nd Quarter 2016 7 PROJECT SPOTLIGHT
