Consultant Contract
PROPOSED MOTION
"The City Council approves a consultant contract in the amount of$198,142.00 with WSB &
Associates and authorize the preparation of a feasibility study for the Orchard Lane Area Street
and Utility Reconstruction Project No. 18-01.
City Council approval requires a simple majority vote of the City Council present."
DISCUSSION
The Capital Improvement Program has planned for the reconstruction of the streets,replacement of
the watermain, and replacement/repair of the sanitary and storm sewer systems within the Orchard
Lane area in the summer of 2018. The proposed project extents are illustrated in Figure 1.
These streets were selected using the City's Pavement Management Program and site investigations.
This project includes approximately 0.7 miles of streets. Sixty-Fourth (64th) Street was constructed
in 1997 and Forest Circle was constructed in 1975; all other streets in the project area were
constructed in 1971. The streets within the project area were sealcoated in 1994 and 1999. The
2014 surveyed pavement conditions are shown in Figure 1 and range from 0 to 33.4. A PCI of 100
represents a new street.

Forest Circle and 64th Street are urbanized; the remaining streets in the project area are a rural
section with no defined ditch. Concrete curb and gutter is proposed to be added to the rural street
sections if adequate stormwater rate, volume and water quality features can be incorporated into the
design. The street widths in the project area are summarized in the table below. The streets are
proposed to be reconstructed to the existing widths due to site constraints and existing right-of-way
widths.
Street Width Right of Way
Orchard Lane - Minnewashta Woods Drive to Forest Avenue 22 to 23 feet 60 feet
Orchard Lane - Forest Avenue to Oriole Avenue 22 feet 60 feet
Forest Avenue - Orchard Lane to Forest Circle 23 feet 60 feet
Forest Avenue - Forest Circle to cul de sac 22 feet 60 feet
Forest Circle- Forest Avenue to cul de sac 26 feet 60 feet
Oriole Avenue - Highway 7 to 64th Street 20 feet 30 feet
64th Street West- Oriole Avenue to cul de sac 26 feet 50 feet

The water main alignment, material and diameters are shown in Figure 2. There is one documented
water main break within the project area. All public water main, water services within the right-of-
way and curb stop boxes will be replaced. The water main extension to Highway 41 is proposed be
replaced as well; replacement of the water main underneath Highway 41 will be a bid alternate to the
project. The 10-inch water main will be replaced with 12-inch water main.

The sanitary sewer within the project area consists of eight and 10-inch PVC pipe as shown in
Figure 3. It is anticipated that some sanitary sewer mains will need to be repaired or replaced along
with some services. The City will have the sewer lines televised to determine the scope of sanitary
sewer repairs and replacement. Inflow/infiltration barriers will be installed in all manholes.

The public storm sewer within the project area is shown in Figure 4. With the exception of the east-
west portion of 64th Street, the project area is not serviced by storm sewer. The City's consultant
will analyze the project area for potential storm runoff treatment options that can be constructed to
treat runoff from the project area.

ENGINEERING SERVICES
Consultant engineering services would be needed for the street project including preparation of the
feasibility report, preliminary and final street and utility design, and preparation of as-built drawings.
Construction administrative and observation services are proposed to be performed by City staff.
Staff sent a request for proposals to two engineering companies: Kimley-Horn &Associates and
WSB & Associates. Proposals were received from both consultants and are summarized below:
Kimley-Horn & WSB &
Associates Associates
Submitted prior to the deadline ✓ ✓
Proposal format V V
Transmittal letter submitted ✓ V
Members of the consultant team identified ✓ ✓
Understanding of the project V V
Total Hours 1,787 1,390
Total Cost $219,880 $198,142
The proposed WSB team has extensive street and utility reconstruction project experience including
the following projects in Chanhassen: Minnewashta Manor(2017), Minnewashta Heights (2012),
Red Cedar Point (2011), and the Erie Avenue Area (2010). Their work in Chanhassen and other
communities has been satisfactory. The consultant contract will be a time and materials based work
not-to-exceed amount.
As with all engineering contracts, the consultant must submit periodic invoices that staff will review
before processing. The consultant will be required to submit timesheets verifying the hours worked
on the project and expense sheets. Staff will review the invoices and expense sheets for accuracy
and conformance to the contract.
FUNDING
Budgets for the proposed work have been included in the 2017 CIP. The budgets will need to be
reviewed and updated based upon current construction cost estimates and after the feasibility report
is drafted. Funding for the project is proposed to come from many sources and has been budgeted
for in the 2017 Capital Improvement Plan as follows:

Description
Annual project to rehabilitate and reconstruct streets in the City. Current 5-year plan shows the following neighborhood areas: 1p
2017-Minnewashta Manor area and Lake Susan Hills Drive area
MSA-Park Road and Park Place
2018-Orchard Lane area

2020-Chan View area
MSA-Lake Lucy Road(Highway 41 to Galpin Blvd)and trail
2021 -Stone Creek area and Ches Mar Drive rill
Justification
The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the jp
life of the street and is cost effective,a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
Rehabilitation projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have
deteriorated to a point where rehabilitation will no longer be practical,reconstruction of the street is necessary. A feasibility study is written to
consider the merits of the project and scope of work.
