Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a planned contract modification for professional engineering services with Stantec Consulting Services Inc. for the Blueprint Tulane / Findley Area Integrated Solutions, CIP #650870-110164, in an amount up to $758,793.30.
The City of Columbus and the State of Ohio entered into a consent order in August of 2002 to resolve sanitary sewer overflow (SSO) related concerns for the City’s sanitary sewer system. The consent order requires the City to develop and implement a program to provide adequate capacity in the collection system, taking all feasible steps to address SSO’s. This project is required to comply with Ohio Environmental Protection Agency’s consent order requiring mitigation of Design Sewer Relief (DSR) activations to the 10-yr level of service. The City proposes to accomplish this via elimination of inflow and infiltration into the sanitary sewer system, and the construction of green infrastructure to capture and treat the resulting stormwater runoff.
To date, the consultant has conducted the required field investigations, property investigations, and alternative analysis to determine the preferred alternative within the project area. The consultants have used this data for the report and to assemble the 30% plans. They are currently working towards their 60% plan submittal. Additionally, the consultants have completed the 90% plans for the Walhalla Ravine Restoration part of the project and are now working towards the final plans.
Future work will concentrate on finalizing the project construction plans, assembling the construction documents, bidding the work, and conducting engineering services during construction.
The Community Area is Clintonville - 39.
