Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering agreement with Arcadis US, Inc. for the Kerr/Russell Inflow Redirection Project, CIP 650790-113180. The work for this project consist of designing approximately 1,800 linear feet of new storm sewer to redirect sources of public stormwater inflow from approximately twenty (20) acres of the Kerr Russell combined sewer shed. The public stormwater runoff in this area flows to the existing Kerr Russell Combined Sewer Overflow (CSO 08) regulator 0011C2430, located in Kerr Street near its intersection with Eden Alley. The public stormwater runoff will be redirected into the existing 48-inch diameter combined sewer at manhole 0011C1722 located approximately 20 feet southeast of the Kerr Russell CSO regulator.
The project is anticipated to have unknown connections to the storm sewers in the Kerr/Russell project area. The Consultant will need to identify and design to redirect the unknown connections to the appropriate public storm sewer or sanitary sewer. The Consultant is to assume approximately one hundred ten (110) properties to be tested per SS-11 (Lateral status determination) for this proposal in order to ensure no sanitary connections are directed to new storm sewers.
Planning Area Near North/University - University District 44
2. PROJECT TIMELINE: Detailed design is expected to take 2 years to complete.
3. EMERGENCY DESIGNATION: Emergency designation is not requested at this time
4. CONTRACT COMPLIANCE NO: 57-0373224 | Exp. 03/19/2021| Vendor # 009409
5. ECONOMIC / ENVIRONMENTAL IMPACT: The project will reduce flooding and add green infrastructure; this will improve quality of life and add to property values in the project area. The project is required by the Combined Consent Order and will aid water quality in the Scioto River by reducing combined sewer overflows from the project area.
