Explanation

1. BACKGROUND:

This legislation authorizes the Director of Public Utilities to enter into an engineering services agreement with AECOM Technical Services, in the amount of $271,210.00 for professional engineering services for the Scioto River Stage Prediction Augmentation Project for the Division of Sewerage and Drainage.

The City of Columbus, Division of Sewerage and Drainage (DOSD) maintains and operates components of the West Columbus Local Protection Project (WCLPP - a.k.a. "the Franklinton Floodwall"). The WCLPP centerline of protection is comprised of levee embankments and floodwall sections along with other components like a flow control structure in Rhodes Park with an associated upstream McKinley Avenue emergency overflow structure, several pump stations, gate wells, and both stop log and sandbag gate closures.

Currently, the City relies upon the National Weather Service (NWS), Advanced Hydrologic Prediction Service (AHPS) for these flood predictions. In the past this service has provided flawed information. As a consequence, the City seeks to fully investigate the accuracy, precision, and reliability of every aspect of its current methodology in receiving and employing real time rain data and associated flood forecast information; including augmenting and refining all rain and stream gauging along with augmenting, refining, and/or replacing the NWS AHPS modeling and weather prediction services with our own.

The Engineer, AECOM, is to evaluate all applicable services, methods and operations; recommend augmentations and/or replacements to any and all parts of the process to make the system as more accurate, precise, and reliable; and then to implement chosen augmentations.

For funding purposes, this is a two-part project; first to investigate, evaluate, and recommend augmentations to all aspects of the data gathering and flood elevation predictions. The second part, funded as a subsequent modification to the origina...
