Improvement Project No. 87-2
I
As requested by the City Council, the West 78th Street Detachment construction
I documents have been updated to reflect the current project scope. The plan set
is quite extensive and, as such, is not included in the Council packet. A copy
of the plan set is available for review in the Engineering Department.
I The plan set has been modified slightly to include the turn lane construction on
West 78th Street and on Market Boulevard for the Market Square site development
and also a turn lane on westbound Bawling Alley Road for the relocated bus
I shelter. The engineer's cost estimate reflects these increases and, in the case
of Market Square, the turn lane improvements will be assessed back directly to
the property owner. By executing the development contract, the developer will
II waive his rights to contest these assessments thereby guaranteeing reimbursement
to the City.
The revised engineer's estimate is summarized in the attached letter from BRW
I and includes the costs for these turn lane modifications. The plans will be
submitted to the various regulatory agencies for their review after Council
approval. We anticipate advertising for bids in February to take advantage of
I the bidding climate at that time such that the project construction can start
immediately when weather permits in mid-April, 1991. Project completion through
the first lift of asphalt is scheduled for October of 1991.
II It is therefore recommended that the West 78th Street Detachment construction
plans and specifications be approved and authorization given for bidding.

IPlan and Specification Approval
Dear Mr. Warren:
We are currently completing plans and specifications for the West 78th Street
Detachment project. The plans and specifications detail the requirements for the
' construction/reconstruction of West 78th Street from County Road 17 to Kerber
Boulevard and the reconstruction of County Road 17 from Trunk Highway 5 to a
point approximately 2,600 feet north.
' The project includes water main, sanitary sewer and storm sewer utility
construction as well as bituminous paving, landscaping and streetlighting
improvements. The project also includes the construction of a storm water
' detention/treatment basin in the northwest corner of the Trunk Highway 5 and
County Road 17 intersection.
' In addition, improvements required by the construction of the Market Square
development have been included as a part of the project as requested by City
staff. The plans and specifications detail the requirements for the construction
' of right turn lanes on West 78th Street and Market Boulevard for proposed Market
Square driveway entrances, and the construction of a right turn lane on Bowling
Alley Road. The turn lanes were not previously included as a part of the project
during the original or reinitiated feasibility stages.
We have completed an Engineer's Cost Estimate for the project as summarized
' below. The project cost estimate previously provided for the recent re-
initiation of the project is also shown for your information and comparison.
