2016 Street Reconstruction Project No. 16 -01: Approve Consultant
Contract; Authorize Preparation of Feasibility Study
PROPOSED MOTION
"The City Council is recommended to approve a consultant contract in the
amount of $208,737.00 with WSB & Associates and authorize the preparation
of a feasibility study for the 2016 Street Reconstruction Project, No. 16 -01.
City Council approval requires a simple majority vote of the City Council
present."
The Capital Improvement
Program has planned for
reconstructing the
Minnewashta Manor area
(north of Lake
Minnewashta) next year.
The streets in
Minnewashta Manor were
selected using the City's
Pavement Management
Program and site
investigations.
The streets in this project
area were constructed in
1971. The streets are in poor condition with pavement condition indices ranging from
www.ci.chanhass
Webss en.mous 9 to 47, with an average of 31. A PCI of 100 represents a new street. Streets with a
PCI below 45 typically indicate distresses that require a full reconstruction, therefore
it is no longer cost effective to repair the streets with minor maintenance or perform a
bituminous overlay.

The street widths vary between 21' and 21' within 50' or 60' wide right of way. The streets are
proposed to be reconstructed to the existing widths. Concrete curb and gutter is anticipated to be
added to this area if adequate storm water rate, volume and water quality features can be
incorporated into the design.

Staff proposes to
replace the water o
main with PVC a
water main. All
services would also be replaced. Alternatives to open cut installation, such as pipe bursting and
directional drilling will be bid as a potential cost - saving measure.
The sanitary sewer
has been televised.
Staff will review the
information to
determine the
condition and look
for evidence of
inflow /infiltration
into the system.
A forcemain from
Lift Station 4 also
lies within the
project area. There
are no known issues
with this forcemain.
An anode bag will
be added to act as a
sacrificial material
to prolong the life of
the forcemain.

The project area is developed therefore there is minimal space to provide traditional stormwater
management, namely curb and gutter, storm sewer and treatment ponds. The feasibility study will:
• Identify and address existing infrastructure and drainage issues
• Review existing City and Minnehaha Creek Watershed District (MCWD)
hydraulic and hydrologic models for issues
• Provide possible solutions to identified issues
Address current National Pollutant Discharge Elimination System (NPDES) and MCWD
requirements
• Identify if project scope exceeds the threshold for each agency and design
accordingly
• Identify potential areas for water quality treatment
• Identify potential areas for abstraction through infiltration, capture and use or
other methods
• Provide discussion of infeasibility if that is the findings
• Identify areas where increases in impervious surface may be minimized
• Review City wetland protection plan, MCWD wetland protection plan, National Wetland
Inventory (NWI), Public Waters Inventory (PWI) and other available resources for
potential wetlands within the project area, delineating wetlands where necessary.
There are overhead private utilities within the project area. The private utility companies will be
notified of the proposed project and asked to provide an estimate to bury the utility. Should the
neighborhood wish to pursue burying the private utilities, 100% of the cost will be assessed to the
benefitting property owners.
Project Financing
Budgets for the proposed work have been included in the 2015 CIP. The budgets will need to be
reviewed and updated based upon current construction cost estimates and after the feasibility report
is drafted.
Assessments will be based off the City's assessment practice of assessing 40% of the street
improvements to the benefiting properties on a per lot basis. The assessments would be proposed for
10 years at a preliminary 6% interest rate. A consultation report will be drafted to help determine
the final assessment amount.
The Engineering Department will host neighborhood meetings to answer resident questions about
the proposed improvements and assessments. These meetings also give staff an opportunity to
gather additional information about the area to help make the project successful.
Engineering Services
Consultant engineering services would be needed for the street project. The engineering services
would include feasibility report preparation, final design and construction administrative services.

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:
The proposed WSB team has extensive street rehabilitation project experience including the
following projects in Chanhassen: 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
Funding for the project is proposed to come from many sources and has been budgeted for in the
2015 Capital Improvement Plan as follows:
Revolving Assessment Fund - Street Improvements including Assessments
Stormwater Utility Fund — Storm Sewer Improvements
Sanitary Sewer Utility Fund — Sanitary Sewer Improvements
Water Utility Fund — Water Main Improvements

nnual project to rehabilitate and reconstruct streets in the City. Current 5 -year plan shows the following neighborhood areas:
2015 - Carver Beach area (south and west of Carver Beach Road)
MSA - Kerber Blvd overlay (north of West 78th Street) and Dakota Ave (Hwy 5 to Lake Dr E)
2016 - North Manor Road, Washta Bay Road, Tanagers Lane, Sandpiper Trail, Piper Ridge Lane and Minnewashm Woods Drive
MSA - Park Road overlay and Park Place
2017 - Flamingo Drive area, Clues Mar Drive, Lone Cedar and Saddlebrook Pass neighborhood
MSA - Bluff Creek Drive overlay and Bluff Creek Drive Trail extension.
2018 - Orchard Lane, Forest Avenue, Forest Circle, Oriole Avenue, 64th Street and 96th Street
2019 - Fox Path area, Frontier Trail (north of 77th Street), Choctaw and Kurvers Point
Justification
City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the
of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
abilitation projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have
:riorated to a point where rehabilitation will no longer be practical, reconstruction of the street is necessary. A feasibility study is written to
sider the merits of the project and scope of work.
Highway 212 improvement project included a pedestrian trail along the first 2,500 feet of Bluff Creek Drive. The resulting "gap" represents a
;ing link in the City's trail system south to Flying Cloud Drive. Bluff Creek Drive is a difficult stretch of road to negotiate as a pedestrian in
3hsence of a trail. This trail seement is nlanned to be constructed alone with the 2017 MSA street reconstruction.

Description
Replacement of existing water mainlines incoordination with the reconstruction of the City street projects or minor fixes of water distribution
system for street rehabilitation projects.
Justification
The City considers the condition of the existing utilities in the process to select streets for rehabilitation in an effort to realize cost savings by
consolidating these projects and also to avoid potential cuts in recently improved streets. If significant repairs are necessary to the existing water
main, replacement may be the most cost effective option. Given the highly corrosive soils in the City, water main replacement is an ongoing
project in the City.
