Parkhill, Smith and Cooper, Inc. in the amount of$138,954 for engineering
services related to determine the best site for a new raw water pump
station, routing for new raw water lines to the water treatment plant and
routing a new potable waterline to serve the proposed golf course club
house project. An exhibit showing the study area is attached.
In coordination with the US Army Corps of Engineers (USACE), additional
environmental and archaeological issues were identified as needing
further study. This additional effort was not in the original scope of the
contract.
If approved, the total engineering services contract for the siting study will
be $173,714.83 which exceeds the authorized appropriation of $150,000.
As such, this action also includes an additional $23,714.83 in
appropriation from the Utility Enterprise Capital Fund.
Staff recommends approval.
