SUBJ: 2015 Street Rehabilitation, Kerber Boulevard (Powers Boulevard to W.
78th Street) Project No. 15-02- Approve Plans and Specifications;
Authorize Advertisement for Bids
PROPOSED MOTION
"The City Council approves the plans and specifications for the 2015 Street
Rehabilitation, Kerber Boulevard (Powers Boulevard to W. 78th Street) Project
No. 15-02 and authorizes the advertisement for bids.
City Council approval requires a simple majority vote of the City Council
present."
BACKGROUND
At the August 11, 2014 work session, staff reviewed with Council the proposed 2015
Street Improvements to the Carver Beach area. Kerber Boulevard, a Municipal State Aid
Route, is also proposed to be resurfaced in 2015.
On October 27, 2014, the City Council authorized preparation of the feasibility study.
On December 11, 2014, staff held an open house for the proposed project.
At the December 8, 2014, City Council meeting, the feasibility study was accepted and
the public hearing was called for February 9, 2015.
The City Council authorized the preparation of plans and specifications at the February 9,
2015 meeting.
DISCUSSION
Website Every year the City considers streets that are in poor condition to be rehabilitated or
www.ci.chanhassen.mn.us reconstructed. For the 2015 Street Rehabilitation Project, staff is proposing to
rehabilitate approximately 1.4 miles of Municipal State Aid street, Kerber Boulevard.

This street was identified by the
City's Pavement Management
software in conjunction with
site investigations.
The proposed improvements
generally consist of milling four
inches of pavement and
repaving.
Severe pavement and subgrade
distresses will be removed and
replaced.
Kerber Boulevard is an urban
street section. Damaged curb
and gutter will be replaced with
this project.
Minor drainage improvements
are also proposed to be
addressed.
The water main is thought to be
in relatively good condition
since there is only one
documented water main break
in the area.
The sanitary sewer system in
the project area was televised
and staff received the results
December 18, 2014. Upon
review of the televising records,
it is recommended some of the
sanitary sewer should to be
replaced due to sags in the pipe.
Some minor manhole work is
also proposed.

Load related distresses —where the base material under the roadway cannot support the weight of
the traffic on the street— decrease the PCI more so than anon -load distress. An example of a
load related pavement distress is an alligator crack. A transverse crack is an example of a non-
load pavement distress as it is caused by exposure to repeated temperature extremes.
Example of an alligator crack
The severity of the pavement distress also
factors into determining the PCI for a street
segment. The severity is determined by the
dimension of the pavement distress. For
example, a low severity pothole is less than
one inch deep, medium severity is one to two
inches deep, and a high severity pothole is
more than two inches deep. The more severe
the pavement distress, the lower the PCI.
The PCI also accounts for the number of
distresses present. For example, the more
potholes within a street segment, the lower
the PCI.
The PCI of the street segments from the 2013
survey are shown on the adjacent graphic. A
PCI of 100 represents a new street. For a
local street, a PCI between 45 and 65
typically warrants a mill and overlay.

The storm manholes in the area have been inspected. These manholes do not meet the City's
current construction standards; however they will not be replaced at this time for the following
reasons:
1. They are still functioning and replacement costs would exceed the amount budgeted for
storm sewer improvements.
2. The street costs would increase due to the area that would be disturbed.
3. The time required to excavate and replace the structures would delay the project.
At this time, deteriorated rings within the storm manholes will be replaced and the circular inlet
grates will be replaced with vane grates to improve inlet efficiency.
Example of a circular inlet grate
The trail along Kerber Boulevard has a low PCI
rating as shown on the graphic to the right, and is
recommended to be replaced at this time. Staff is
recommending the trail be bid out as an alternate bid.
No new trail segments are proposed to be added to
Kerber Boulevard.
The trail improvements will be bid as an alternate in
the event that the bids come in higher than the
amount budgeted for the project.
Curb ramps to the trail along Kerber Boulevard
should be replaced in accordance with the Americans
with Disabilities Act requirements. This work will be
completed regardless of the trail improvements.

PROJECT FUNDING
Special assessments to the benefitting properties are proposed to pay for a portion of the
proposed 2015 Street Rehabilitation Project No. 15 -02 per the City's assessment practice. The
City's share of the project is proposed to be paid for with Municipal State Aid funds (gas tax
funds) which the City annually receives from the State. However, the City will need to advance
funds from the State Aid account since the City's account does not have sufficient funds to pay
for this project. The State encourages Cities to advance fund projects since the State Aid account
has sufficient funds to cover these types of projects. The State does not charge any interest for
these advancements. The sanitary sewer improvements are proposed to be paid for by the
Sanitary Sewer Enterprise Fund. The preliminary cost and funding for the project is shown
below:
Funding ource Estimated Amount
g Project Cost Budgeted
Municipal State Aid Fund $1,3851000.00
Assessments
$24,563.41
$1,400,000.00
Sewer Utility Fund $47,000.00 $85,000.00
Total $1,456,563.41 $1,485,000.00
Kerber Boulevard is a 40 -foot wide collector road with few properties having direct access to the
street. The City's practice is to assess benefitting properties 40% of the equivalent cost of a 31-
foot wide residential roadway. Due to the limited number of benefitting properties, assessments
are proposed to be established by a front- footage basis.
The IRET (Byerly's) property was assessed for 100% benefit to W. 78th Street with the 2011
resurfacing project and therefore is not included in the proposed assessment roll for City Project
No. 15 -02.
The preliminary assessment calculations are shown below.
Estimated cost of Kerber Boulevard resurfacing, 31 -foot wide road: $906,675.00
Total front footage of Kerber Boulevard: 15,242 ft.
$906,675.00 15,242 ff = $59.49/ff
40% assessed: 40% of $59.49/ff = $23.79/ff
Carver County CDA: 397 ff x $23.79/ff = $9,444.63
West Village Townhomes: 635.51 ff (per CIC plat) x $23.79/ff = $15,118.78
$15,118.78 = 64 units (per CIC plat) _ $236.23/unit
The cost estimate includes an 8% contingency and 5% indirect costs.

Description Total Project Cost: $2297699500
Annual 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 Minnewa.shta Woods Drive
MSA - Park Road overlay and Park Place
2017 - Flamingo Drive area, Ches 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
MSA - Minnewashta Parkway overla
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 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.
The Highway 212 improvement project included a pedestrian trail along the first 2,500 feet of Bluff Creek Drive. The resulting re p "gap" resents a
missing 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
the absence of a trail. This trail se ent is lanned to be constructed along with the 2017 MSA street reconstruction.
