MEMORANDUM
TO: Paul Oehme, Director of Public Works /City Engineer
FROM: Alyson Fauske, Assistant City Engineer a�
DATE: October 27, 2014
SUBJ: 2015 Street Rehabilitation Projects No. 15 -01 and 15 -02: Authorize
Preparation of Feasibility Study
PROPOSED MOTION
"The City Council approves a resolution authorizing the preparation of a
feasibility study for the 2015 Street Rehabilitation of Carver Beach Area,
Project No. 15 -01 and Kerber Boulevard Improvements, Project No. 15 -02.
City Council approval requires a simple majority vote of the City Council
present."
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.
Every year the City
considers streets that
are in poor condition to
be rehabilitated or
reconstructed.
For the 2015 Street
Improvement Projects,
staff is proposing to
rehabilitate
approximately 4.3
miles of streets in the
Carver Beach area and
1.4 miles of Kerber
Boulevard.
Website
www.ci.chanhassen.mn.us The street segments
within the proposed
project were identified
by the City's Pavement Management software in conjunction with site investigations
and are shown on the map above.

The proposed improvements generally consist of milling and repaving the pavement surface. Severe
pavement distresses will be removed and replaced. Minor drainage improvements are also proposed
to be addressed in the project areas. Miscellaneous water main and sanitary sewer manhole repairs
are proposed for replacement in these areas.
A feasibility report will be prepared by the Engineering Department staff. Design of the Carver
Beach area improvements will be done in- house. Due to the large scope of the projects, plans for the
Kerber Boulevard improvements will be completed by Kimley -Horn and Associates. Construction
observation will be done by City staff.
Project 15 -01: Carver Beach Area
Approximately 4.3 miles of streets are proposed to be milled and overlaid within the Carver Beach
Area. The streets in this area are 39 years old with the exception of Nez Perce Court, which was
constructed in 1980. The streets were sealcoated in 1993 and 1998 and various areas were heavily
patched in 2011. The northern portion of Lotus Trail was overlaid by City forces in 2006 and is
therefore excluded from the proposed project.
The street conditions in this area were last surveyed in 2013. The Pavement Condition Indices (PCIs)
from the survey are shown on the map below.

A PCI below 45 typically warrants reconstruction; however, the utilities in the area are in fair
condition and therefore staff is recommending a full depth mill and overlay of the streets at this time.
Ringo Drive is currently gravel and is proposed to be paved. The profile of Woodhill Drive is
proposed to be raised at the low point to alleviate some drainage concerns. Subgrade corrections
would be done as needed.
There is very little concrete curb and gutter within this project area. The area is fully developed
therefore there is no area to construct conventional stormwater management facilities. Staff will
examine the south end of Lotus Trail to identify potential stormwater improvements in the area. Staff
will continue to gather information on the existing storm sewer pipes and draintile within the area and
provide storm sewer improvement recommendations in the feasibility report.
The sanitary sewer system will be televised to determine the scope of repair work. The Utility
Department has performed a visual inspection of the sewer manholes and provided a list of work to
be completed with this project.
The water main in this area is ductile iron. City records do not show any water main breaks in this
area. It is recommended to replace the bolts on the valves and some hydrants at this time. Most
hydrants in the area are not easy to maintain and can cause operational problems. Typically, gate
valve bolts that are in the ground and exposed to soils for this length of time have a tendency to
corrode and break.
Proiect 15 -02: Kerber Boulevard (north of West 78th Street
Kerber Boulevard north of West 78th Street to Powers
Boulevard is proposed to be resurfaced in 2015. This project
area consists of 1.4 miles of improvement. The portion south
of West 78th Street was resurfaced in 2011 with the West 78th
Street improvements. Funding for this project is predicated on
MnDOT advancing funds from the state aid account.
Kerber Boulevard was constructed in 1980, with the exception
of the southern leg between City Hall and West 78th Street,
which was constructed in 1940. The street was overlaid in
1996 and last seal coated in in 2007.
The PCI of the street segments 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. Subgrade corrections would be done as needed. The
street is urbanized. Damaged curb and gutter will be replaced.
Some storm sewer improvements are anticipated.

There is no sanitary sewer within Kerber Boulevard. Sanitary sewer crossings will be televised to
determine the scope of repair work.
Ductile iron water main is within the street. There is one documented water main break just north of
West 78fl' Street. Staff recommends that the valves and some of the hydrants be replaced in
conjunction with the project. Typically, gate valve bolts that are in the ground and exposed to soils
for this length of time have a tendency to corrode and break.
Curb ramps to the trail along
Kerber Boulevard will be replaced
in accordance with the Americans
with Disabilities Act requirements.
The trail along Kerber Boulevard
has a low PCI rating as shown on
the graphic to the right, and should
be replaced at this time.
No new trail segments are
proposed to be added to Kerber
Boulevard.
The loop detectors to the signals at
West 78a` Street will be evaluated
to determine if they will be
impacted by the proposed
improvements.
The City has received requests to
install a pedestrian crossing from
the Chanhassen Library to the strip
retail center on the west side of
Kerber Boulevard and where
Redwing Lane intersects Kerber
Boulevard. The City's consultant
will analyze these areas and
provide a recommendation.

PROJECT FUNDING
Funding for the project is anticipated to come from several sources. Forty percent (40 %) of the street
improvement costs in the Carver Beach area would be assessed back to the benefiting property
owners, per the City's assessment practice. The remaining 60% of the street costs would be a City
cost.
The majority of the Kerber Boulevard road and trail improvements will be paid using Municipal State
Aid (MSA) funds from the State. A portion of the street improvement costs are proposed to be
assessed to the Carver County CDA and the townhome development on the southwest corner of
Kerber Blvd and Santa Vera Drive. The proposed assessment methodology and estimated assessment
will be included in the feasibility report.
The storm sewer, sanitary sewer and water main improvements replacement costs would be funded
by the respective utility funds in the annual utility budgets.
The following is the anticipated recommended project budget and funding sources:

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 78tb 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 Minnewashta 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 overlay
uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the
e street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective.
anon projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have
ted to a point where rehabilitation will no longer be practical, reconstruction of the skeet is necessary. A feasibility study is written to
the merits of the project and scope of work
'.12 improvement project included a pedestrian trail along the fast 2,500 feet of Bluff Creek Drive. The resulting "gap" represents a
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
a trail. This trait semrent is planned to be constructed along with the 2017 MSA street reconstruction.

City considers the condition of the existing utilities in the process to select streets for rehabilitation in an effort to realize cost savings by
;olidating these projects and also to avoid potential cuts in recently improved streets. If significant repairs are necessary to the existing water
i, replacement may be the most cost effective option. Given the highly corrosive soils in the City, water main replacement is an ongoing
ect in the City.
