• Complete a 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 safety edge and center rumble stripe from approximately the Landscape Arboretum
entrance to Commercial Ave. in Victoria.
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 atjustified 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 TH5IMinnewashta
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.
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.
PROJECT COST
The project cost is estimated at $7,600,000.
Based on MnDOT's latest cost estimate, the City of Chanhassen participation is roughly $180,000
for the federal funding grant match requirements which is broken down as follows:
$70,000 (based on current estimate) for matching dollars for safety improvements (HSIP
funding) on TH 5 at Minnewashta Parkway area. The grant application was for a $100,000
match.
$110,000 (based on current estimate) for pedestrian underpass at Minnewashta Parkway.
The grant application was for $245,000 in matching funds.
The City of Chanhassen's cost participation will be refined as final design cost estimates are further
detailed. The actual amount may be a lump sum or may depend on the awarded bid if that is how the
agreement is structured.
The City of Chanhassen did take the lead in applying for federal grants, however, other agencies will
benefit from these improvements. Staff has discussed with other agencies the need to help pay for
the matching funds and indirect costs for the federal grant improvements. It is staff's belief that
Carver County, the City of Victoria and the Minnesota Landscape Arboretum should help pay for the
trail underpass at Minnewashta Parkway. Likewise, the City of Victoria should help pay for the
matching funds for the safety improvements on TH 5 since some of these improvements are in the
City of Victoria city limits.
MUNCIPAL CONSENT
Since the municipal consent hearing on April 11, 2011, no additional residential concern has been
brought to staffs' attention other than those that were discussed at the public hearing. Therefore staff
recommends approval of the MnDot layout and support resolution.
