SUBJECT:
title
Consideration of a Professional Services Agreement (COF Contract No. 2015-0186) with Civil & Environmental Consultants, Inc. for Survey and Design of the Harpeth River Bank Stabilization Project at the Franklin Water Reclamation Facility in an amount not to exceed $74,400.00 (07/23/15 CIC 4-0)
body
Purpose
The purpose of this memo is to provide information to the Franklin Board of Mayor and Aldermen (BOMA) concerning the Harpeth River Bank Stabilization Project at the Franklin Water Reclamation Facility.
Background
There is currently severe bank erosion along the Harpeth River at the Water Reclamation Facility. If this erosion continues, it will threaten a 12-inch force main that currently provides sanitary sewer service to Westhaven. In addition, the Water Management Department currently has two "cat-walk" type structures utilized by City staff for mid-stream sampling. The banks along these "cat-walk" type structures has receded approximately 2 feet in the last year. The purpose of this project is to restore and stabilize the banks for the river and also to protect our current infrastructure (See Exhibit A). We will accomplish this by incorporating natural steam design principles, bioengineering and traditional stabilization techniques to the left descending bank and riparian area.
Financial Impact
The estimated design and construction cost of the project is shown below:
$74,400 - CEC Design and Survey (Approved in the FY 2015-2016 Stormwater Budget (89531 Machinery & Equipment))
$20,000 - Future Geotechnical Engineering (Approved in the FY 2015-2016 Stormwater Budget (89531 Machinery & Equipment))
$500,000 - Future Construction Project (To be budgeted in FY 2016-2017 Stormwater Budget)
$594,400 Total Estimated Project Cost
