2010 Street Reconstruction Project No. 10-01: Approve Consultant Contract;
Authorize Preparation of Feasibility Study
PROPOSED MOTION
"The City Council is recommended to approve a consultant contract in the amount of
$281,055 with WSB & Associates, Inc. and authorize the preparation of a feasibility
study for the 2010 Street Reconstruction Project, City Project 10-01.
City Council approval requires a simple majority vote of the City Council present."
BACKGROUND
The Capital Improvement Program had planned for reconstructing the Erie Avenue
neighborhood (Chanhassen Estates, south of Lake Drive East) and the Red Cedar Point
neighborhood next year. The streets proposed for reconstruction were chosen using the
City's Pavement Management Program and were identified due to utility problems in the
area. Below is a brief description on the projects.
ERIE A VENUE NEIGHBORHOOD (CHANHASSEN ESTATES)
It is proposed that 0.73 miles of streets in this area be
reconstructed. The streets in the Erie A venue
Neighborhood are 38 years old and cannot be
maintained properly with minor maintenance or even
a bituminous overlay. The streets are in poor
condition with an average pavement condition index
of 28; a road under 45 typically indicates distress that
would require a full depth reconstruction.
Dakota Lane and Erie Circle were overlaid by City
crews with a thin bituminous pavement in 2001 due
to severe washouts and distressed pavement areas.
These streets' average pavement condition index
currently is 52 which is higher than most of the other
streets however it is anticipated these streets will

degrade more quickly in the coming years. These streets should be included when the Erie Avenue area is
reconstructed so a gap of old street section is not left.
The watermain in this area is cast iron pipe and has nine documented breaks. The sanitary sewer has been
televised and shows many areas of groundwater leaking into the pipe and settled pipes that do not flow well
anymore. The storm sewer system should be upgraded and draintile installed. It is proposed to upgrade these
streets to the City's standard pavement section with concrete curb and gutter. The watermain should be
replaced, sanitary sewer system spot repaired, and stonn sewer system upgraded and draintile installed.
RED CEDAR POINT NEIGHBORHOOD
It is proposed that 0.85 miles of streets in this area be reconstructed. Most of the utilities and streets in the
Red Cedar Point neighborhood are also 38 years old. The streets are very narrow in most areas and have a
rural section. Most of the streets are in poor condition with an average pavement condition index of 48. The
streets have been patched several times because of watermain breaks and other utility problems. These
numerous street patches have raised the pavement condition of the streets. However, the streets in general are
in poor condition.
The sanitary sewer has been
televised and shows many
areas of groundwater leaking
into the pipe and settled pipes
that do not flow well
anymore. The area is known
to have a high groundwater
table. There is little
stormwater management in this area and no stormwater collection system.
! i
I '
! !
The watermain in this area is
cast iron pipe and has 12
documented breaks. Due to
the narrowness of the streets
some of the watermain may
need to be directionally
drilled to keep access to the
properties.
N
~ "opo....,~""~,_ A
The streets in this area are proposed to be upgraded to a heavier pavement section but left as a rural section.
Depending upon storm water management practices to be implemented, curb and gutter may be added to
some road sections. There is potentially very little opportunity for stormwater management due to the nalTOW
streets and lack of City-owned property for ponding or other water quality improvements. There may be
opportunity to acquire some property for stormwater management.
The City will need to work with the Minnehaha Watershed District on the project. It is unknown what
stormwater management requirements will be needed due to the non-degradation requirements and the
impending revisions to Rule N of the Minnehaha Creek Watershed District (MCWD). The City will need to
work with the MCWD to identify and fund potential opportunities.

On August 19,2009, a Request for Proposals (RFPs) for this project was emailed to Kimley-Horn and
Associates, Inc. and WSB & Associates, Inc. Both firms submitted a proposal which is summarized as

Base Fee - Red Cedar Point Area $164,960 $141,381
Total Fee $325,675 $281,055
The main difference in the proposals was the time allocated for construction observation and administration.
Kim1ey-Horn proposes 475 hours of construction observation for each project area. WSB proposes 320
hours, however, they have indicated that the construction observer will be on-site, full-time for the duration of
the project and that the City will not be billed for time exceeding 320 hours.
The WSB project team has worked extensively with Minnehaha Creek Watershed District in many
municipalities, including Excelsior, Shorewood, Minnetonka and Minnetrista. The City will need to work
with the Minnehaha Creek Watershed District on storm sewer improvements on Red Cedar Point.
WSB & Associates, Inc. has met the criteria set for this project. They have worked on several projects within
the City including the Sanitary Sewer Inflow and Infiltration and the West-Central Lotus Lake Storm Sewer
Improvement Project. WSB has successfully completed numerous Chapter 429 projects throughout the metro
area. Their work has been satisfactory.

FUNDING
Funding for the project is anticipated to come from several sources. Forty percent (40%) of the street
improvement cost would be assessed back to the benefiting property owners per the City's assessment
practice. The remaining 60% of the street cost would be a City cost. The storm sewer, sanitary sewer and
watermain replacement costs would be funded by the respective utility funds.
The following is the anticipated recommended project budget and funding sources:
Fund
Total
Revolving Assessment fund
Sanitary Sewer Utility fund
Watermain Utility fund
Storm water Utility fund
$1,900,000
$250,000
$700,000
$400,000
$3,250,000
The contract will be a time and materials based work not to exceed amount. Hours will be billed separately
for each project area. As with all engineering contracts, the consultant must submit periodic invoices that
staff will review before processing. The consultant will be required to submit time sheets 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.

Description
Annual project to rehabilitate and reconstruct streets in the City. Current 5-year plan shows the following neighborhood areas:
Residential 2009 - Chaparral, W 78th St, Quattro Dr, Dell Rd, Lakota Ln and Vogelsburg Tr
2010 - Erie Ave area, Red Cedar Pt and Audubon Rd (Lk Dr to Lyman)
2011 _ Carver Beach Rd, Timberwood, Saratoga, Santa Vera, Chippewa, Picha and Kerber (S ofW 78th)
2012 - Greenbriar, Fir Tree, Elm Tree, Dogwood and Shore Drive
2013 _ Frontier Tr (Highland to W 77th), Great Plains (W 78th to Santa Fe), W 77th, Erie Ave (N ofW 77th), Highland (E of
Laredo) and Greenwood Shores
MSA 2011 - West 78th Street Powers to Market
Justification
The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the
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 with utility 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.

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.
