Approval of and authorization to execute Amendment 1 to Agreement for Professional Consultant Services with Cowan Group Engineering, LLC for Elm Creek Trunk Line Improvements (Project No. S.1606)
End
Background:
This project consists of replacing existing 12-inch, 15-inch, 18-inch and 24-inch collector sewer due to capacity limitations during the 5-year design storm between West Florence Street, under the Creek Turnpike and to the Indian Springs Country Club Lift Station. The existing sewer carries flow from the far western portion of the Lynn Lane basin and is not adequately sized for wet weather flows. Backups from the limited capacity cause predicted manhole surcharge in upstream segments during a 5-year storm. The Wastewater System Master Plan identified this project as I.D. LL-GS02, to replace approximately 11,000 linear feet of sanitary sewer trunk line within the Elm Creek basin from just south of the Creek Turnpike to the existing Indian Springs Country Club Lift Station. Amendment 1 is for staking of proposed utility easements, temporary construction easements, and sanitary sewer alignment.
This amendment with Cowan Group Engineering, LLC has been negotiated for $3,500.00 and brings the total contract amount to $391,300.00.
Cost: $3,500.00
Funding Source: OWRB Loan
