PROPOSED MOTION
"The City Council approves the plans for the TH 5 improvements from TH 41
to Victoria Drive (CSAH 11) State Project No. 1002 -89, City project
PW067B2."
City Council approval requires a simple majority vote of the City Council
present.
BACKGROUND
On November 17, 2009, a TH 5 update meeting was held in Victoria with the
stakeholder along the corridor to discuss future upgrades to the corridor.
On June 22, 2010, a neighborhood meeting was held at Victoria City Hall to discuss
the proposed TH 5 improvements planned for the summer of 2012.
On February 14, 2011, staff updated Council at the Work Session on the Municipal
Consent process.
Public Works
On April 11, 2011, a public hearing was held.

The summer of 2012, MnDOT plans to make improvements to approximately a 4-
Web Site
mile segment of TH 5 roughly between the west junction of County State Aid
www.ci.chanhassen.mn.us
Highway (CSAH) 11/Victoria Drive in Victoria and Highway 41 in Chanhassen. The
proposed project will include:
• 4" mill and overlay the entire four mile stretch.

• Reconstruct the bridge over the recreational trail west of Rose Street in Victoria.
• Reconstruct an 800 -foot sink hole /settlement section of road west of 78th Street in Victoria.
• Add capacity, efficiency and safety through turn lane improvements, signal modifications,
ADA improvements, access modifications and drainage improvements.
• Improve pedestrian mobility and safety with a new pedestrian underpass east of Minnewashta
Parkway near the Arboretum.
• Add a safety edge and center rumble stripe from approximately the Landscape Arboretum
entrance to Commercial Avenue in Victoria.
Construction Detour and Staging Plan
The project presents some challenges for traffic control and staging because TH 5 carries almost
27,000 trips per day west of TH 41 and few other routes are in close proximity to serve as a good
detour alternative. The Cities of Victoria and Chanhassen and Carver County staff have been
meeting with MnDOT to try to come up with a staging and detour plan to lessen the impacts on
residents and businesses.
Prior to the majority of the work on TH 5 starting, MnDOT is planning to replace the free right turn
lanes on the east side of TH 41. This work will take approximately 10 days to complete. The work
cannot be completed under traffic. The turn lanes however are planned to be opened over the
weekends and be opened before Memorial Day.
Two segments of TH 5 are anticipated to be closed between the Memorial Day and Labor Day
holidays. One location is for the replacement of a bridge over a recreation trail west of Rose Street
and another is for the reconstruction of pavement west of 78 Street /Stieger Lake Road. Both of
these closures are in the City of Victoria. The official regional detour for this closure for westbound
traffic is TH 41 south to TH 212 west to State Highway 284 north.
The work to be completed between TH 41 and 78 Street /Stieger Lake Road poses a lot of
challenges to construct under traffic. This work includes:
• Reconstruction of the free right turn lanes on the west side of TH 41.
• Lone Cedar Lane roadway extension and access closure.
• Pedestrian underpass, trail and retaining wall construction at Minnewashta Parkway.
• Turn lane improvements at Minnewashta Parkway.
• Shoulder improvements from east of Lone Cedar Lane to Bavaria Road (CSAH 13).
• Right turn lane construction on northbound Bavaria Road at TH 5.
• Pedestrian crossing improvements at Bavaria Road and TH 5.
• Shoulder improvements from Bavaria Road to 78 Street.
• Turn lane improvements at Park Drive /Kochia Lane.
• Storm sewer pipe replacement between Park Drive and 78th Street (2 locations).
To complete this work under traffic will lengthen the time to complete the work, will be less safe for
the driving public and construction crews and the quality of the job will not be as good.

MnDOT is proposing to close this section of TH 5 for 6 weeks. The City of Victoria has approved
the six week closure based on the following criteria:
• Contract would include incentives for work to be completed in less than six weeks (financial
reward /each day the road opens early).
• Victoria and Chanhassen would consider lengthening working hours.
• Work on TH 5 in this area could be staged after July 4th until Labor Day.
• Local detour would be TH 41 to TH 7 to Rolling Acres to 78th Street to Stieger Lake Lane.
• Access would be maintained to homes and business located within the work zones.
• Lone Cedar Lane access to TH 5 would remain open for the six week duration.
• Work on turn lane on northbound Bavaria (requires closure) would occur either before or
after the work above.
Signal Justification
MnDOT is not planning to construct a signal at the intersection of TH 5 and Minnewashta Parkway
with this project because it currently does not meet their minimum threshold, or warrant, for
installing a signal. However, a signal is the number one improvement people who live in this area
have requested. MnDOT's response to this issue is as follows:
Numerous studies conducted around the nation continue to show that traffic
signals cause more overall delay and often result in an increase in the total
number of crashes at an intersection. Studies also show that the rate of red light
running at unjustified signals is higher than at justified ones. This is why the crash
rates at unjustified signals are higher than at justified ones. In the past three
years, at signalized intersections in the Metro area, there have been 54 fatal and
503 "A" injury crashes ( "A" is the most severe injury). Signal justification
warrants were created to limit the installation of signals to locations where their
benefits will be higher than their negative effects.
Signal justification is based on criteria that was developed by the Federal
Highway Administration and adopted as policy by MnDOT. This criteria looks at
traffic volumes, crash history, pedestrians, school crossings, etc. The seriousness
of a crash is not a factor in the crash criteria used in the justification of a traffic
signal. MnDOT is concerned by and works to minimize all crashes. The traffic
volume criteria are based on volumes on the major street and minor street. The
major and minor streets both have to meet minimum volumes in order for these
criteria to be met. For the major streets (on State Highways) in the Metro area,
the minimum volumes are usually always met, which leaves the minor road
volumes as the determining factor if a signal can be justified or not based on
volumes of traffic. The traffic volumes at the intersection of TH 5IMinnewashta
Parkway do not meet the minimum volumes at this time.
As stated above, crash history is one of the criterion of signal justification. This
intersection has had 7 reported crashes in the past three years, of which zero are
considered to be "correctable" with a traffic signal. "Correctable" crashes are

right angle crashes. The crash criteria states that a signal warrant can be met if
there are 5 "correctable " crashes per year.
Based on all of the above, the installation of a traffic signal at this intersection is
not justified at this time.
The Minnesota Landscape Arboretum is considering adding a south leg to the intersection of TH 5
and Minnewashta Parkway in the near future. If this leg is constructed and a majority of their daily
trips to the Arboretum are directed to this intersection, it is anticipated a signal may be warranted at
that time.
Pedestrian Underpass
Currently, there is not a lot of pedestrian movement from Minnewashta Parkway to the Minnesota
Landscape Arboretum. However, the Arboretum wants to encourage more "walk -up" traffic and is
planning to make internal capital improvements for this to happen. The City has partnered with the
Arboretum to encourage the general public to utilize this facility. Chanhassen residents will be able
to cross TH 5 at Minnewashta Parkway with a safe grade separated connection and gain access to the
Arboretum at no cost. The pedestrian underpass will allow the Arboretum to become an extension
of the City's park system for all to enjoy. The City of Victoria is also planning to connect their trail
system to the underpass.
Plan Approval
MnDOT is finishing up the plan sets and hope to have them completed by the end of the October.
MnDOT is requesting the City to approve the plans to keep the project on schedule. The Council
will be asked to approve an agreement between MnDOT and the City covering the City elements of
the project scope. It is anticipated that this agreement will be brought to the Council for approval
before the end of the year.
