Explanation
1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into a professional engineering services agreement with DLZ Ohio, Inc., for the Reservoirs Bathymetric Study, in an amount up to $528,700.00, for Division of Water Contract No. 2062.
This is a contract for Professional Engineering and Surveying Services (Design Professional or “DP” services) to assist the Division of Water in evaluating the available volume in its reservoirs, update area-capacity curves, and evaluate sedimentation rates for its three on-stream reservoirs (Griggs, O’Shaughnessy, Hoover).
The DP will perform bathymetric surveys at the reservoirs using sonar at periods when the reservoir is near or above normal pool. Subsequent computational analysis will evaluate the reservoirs’ capacity and reports, drawings, and models will be submitted to the City to convey the findings.
Community Planning Areas:
Griggs Reservoir: “Northwest”
O’Shaughnessy and Hoover Reservoirs: “N/A”
