CONSIDER APPROVAL OF A RESOLUTION APPROVING THE RECOMMENDED
TRAFFIC SAFETY IMPROVEMENTS ALONG WILDS PARKWAY
HISTORY
At the August 18th, 2003 council meeting, Bryan Fleming addressed the City Council
during the public forum to explain his concerns over vehicles parking along Wilds
Parkway near the driving range at Wilds Golf Club. Also concerned with residents'
safety, the City Council directed staff to explore possible safety improvements. Staff has
also received phone calls from a concerned resident about the safety of pedestrians
crossing at the Wilds ParkwaylWoodduck Trail intersection. To expeditiously complete a
comprehensive traffic study for this area, staff hired Strygar, Roscoe, Fausch (SRF)
Consulting Group as the City's traffic engineer. Both of these issues along with possible
striping changes were included in the study. Attached is the completed report with
findings and recommendations from SRF Consulting Group.
CURRENT CIRCUMSTANCES
Wilds Parkway is a minor collector roadway serving residential neighborhoods and a golf
course. The entire roadway is 33 feet wide except when there is a median, at
intersections including CSAH 82, CSAH 83 and Wilds Ridge. Presently parking is
allowed on both sides of the street except at the medians and on the southwest side of
Wilds Parkway near the Wilds driving range. The posted speed limit is 30 mph.
The traffic issues identified by the residents and studied by our engineer included: speed
and traffic conditions, parking issues, a four way stop at Wilds Parkway and Woodduck
Trail, and a pedestrian crossing to Wilds Park.
Because we are aware of the neighbors' interest in these matters, we sent letters to all
the residents who have direct access on Wilds Parkway to attend tonight's Council
meeting. We have also invited Bryan Fleming and asked him to notify those residents
who signed his petition and any other interested parties he was aware of. We have also
invited the Wilds Golf Club management. While this is not a public hearing, we hoped
that anyone with an interest could be contacted.
The attached report provides details of the findings. The recommendations are:
No Parking: Install "No Parking" signs on the south/west side of the roadway and on
both sides of the street at road segments with a median.
Striping: Striping improvements need to be made along the entire corridor, which
provide delineation of parking and no parking areas as well as traffic lanes.

FISCAL IMPACT:
ALTERNATIVES:
RECOMMENDED
MOTION:
REVIEWED BY:
. I F
Four way stop: A four-way stop at Wilds Parkway and Woodduck Trail does not
meet warrants and is not recommended.
Pedestrian Crossing: A pedestrian crossing is recommended on the north/west
side of the driveway entrance to Wilds Park.
While we will try to arrange for the restriping this year, due to inclement weather
conditions, the new striping plan will more likely be completed next spring, if approved by
the city council.
The study seeks to provide safety to motorists and pedestrians alike. The consulting
engineer found that there is sufficient street width to provide parking on one side and two
lanes of traffic if the striping were realigned to provide sufficient traffic lanes in each
direction. The consultant found that a four way stop at Wilds Parkway and Woodduck
Trail does not meet state standards, nor will it be an effective speed reduction device.
The crosswalk at the entrance to Wilds Park is supported and is consistent with present
statutes requiring motorists to yield to pedestrians in crosswalks. Considering the traffic
speeds identified, the Police Chief will be scheduling enforcement in this area.
The fiscal impact for the City includes approximately $5000 for the traffic engineering
study, which is coming out of the budget line item in the engineering division-
Professional Services. Every year we restripe Wilds Parkway, so the updated striping
plan will not add additional cost. There will be minimal added maintenance costs to
annually update the paint for the recommended pedestrian crosswalk and minimal costs
for adding and installing pedestrian crosswalk warning signs. Enforcement costs are part
of the ongoing Police department budget.
The alternatives are as follows:
1. A motion to approve a resolution approving the recommended traffic safety
improvements along Wilds Parkway.
2. Table this agenda item for a specific reason.
3. Deny this agenda item for a specific reason.
Staff recommends alternative number 1.

SUBJECT: WILDS P ARKW A Y TRAFFIC STUDY
Introduction
As you requested, we have completed a traffic study of Wilds Parkway from CSAH 82 to CSAH
83 in the City of Prior Lake. Wilds Parkway is currently a minor collector roadway serving a
residential neighborhood and golf course. The purpose of this study is to evaluate the feasibility
of parking along the roadway, a pedestrian crossing near the neighborhood park and all-way stop
control at the intersection of Wood Duck Trail.
Roadway Characteristics
Wilds Parkway is currently a 33-foot wide (face-of-curb to face-of-curb) mmor collector
roadway with the following characteristics:
. Roadway width includes a 30-foot wide driving surface with 1.5-foot gutter sections on
each side.
. Roadway design includes horizontal (none more restrictive than the posted speed) and
steep vertical (as high as 6.4 percent) curves.
. Concrete medians exist on Wilds Parkway near its intersection at CSAH 82, CSAH 83
and Wilds Ridge.
. Twenty residential driveways with direct access on Wilds Parkway.
. Seven short cul-de-sacs along Wilds Parkway with limited on-street parking.

Traffic Conditions
Traffic volumes were collected for Wilds Parkway in September 2003 and August 2001. These
daily volumes are shown in Figure 1. It is important to note that during the September 2003
counts, Wilds Parkway was closed at CSAH 83 due to construction. This closure forces all
motorists to access Wilds Parkway from the south at CSAH 82. Therefore, the September 2003
traffic volumes identified in the figure is not an accurate reflection of current traffic conditions.
Speed data was also recently collected along Wilds Parkway. This data was collected using a
HI-STAR unit. The posted speed limit on Wilds Parkway is 30 mph. As shown in the
September 2003 data, the increase in speeds along Wilds Parkway may be a result of motorists'
frustration with road closures and detours related to the current construction along CSAH 42 and
CSAH 83. A summary of this data is as follows:
. Speed data for August 2001 (south/east of Wood Duck Trail) indicated that
approximately 20 percent of the motorists traveling in the southbound/eastbound
direction are traveling at or above 35 mph.
. Speed data for August 2001 (south/east of Wood Duck Trail) indicated that
approximately 50 percent of the motorists traveling in the northbound/westbound
direction are traveling at or above 35 mph.
. Speed data for October 2002 (south/east of Wood Duck Trail) indicated that
approximately 30 percent of the motorists traveling in the southbound/eastbound
direction are traveling at or above 35 mph.
. Speed data for September 2003 (north/west of Wood Duck Trail) indicated that
approximately 60 percent of the motorists traveling in the southbound/eastbound and
northbound/westbound direction are traveling at or above 35 mph. The 85th percentile
speed was 42 mph for each direction of travel.
. Speed data for .September 2003 (south/east of Wild Horse Pass) indicated that
approximately 50 percent of the motorists traveling in the southbound/eastbound
direction are traveling at or above 35 mph.
Parking Issues
Currently, there is a concrete median along Wilds Parkway near its intersection with CSAH 82,
CSAH 83 and Wilds Ridge. The remaining segment of roadway is 33 feet wide with a double
yellow centerline and white fog line on each side. Due to its current width, parking should not
be allowed on both sides of the roadway. No parking restrictions near the south practice range
are currently posted along the south/west side of Wilds Parkway, between Pine View Drive and
Wilds Lane. To address vehicular and pedestrian safety along Wilds Parkway, it is important to
provide a uniform parking policy for the entire corridor. A change in parking restrictions and/or
roadway striping can cause confusion to the motorist and create enforcement problems.
Therefore, parking solutions considered for this roadway include a no parking restriction on one
side or both sides of Wilds Parkway.

Restricting parking on both sides of the entire corridor would significantly impact those residents
with direct access along Wilds Parkway and those living on the short cul-de-sac streets. This
solution is not feasible since it would eliminate any parking along Wilds Parkway at all times of
the day.
Next, two driving lanes with a no parking restriction on one side of the street was evaluated.
With the existing roadway width along Wilds Parkway, it is feasible to allow parking on one side
of the street. However, to provide safe pedestrian and vehicular travel along Wilds Parkway, the
following striping improvements are recommended:
. The absolute minimum width for this type of roadway cross-section is 31.5 feet. This
width accommodates 1.5-foot gutters on each side, a 6.5-foot parking lane and two 11-
foot driving lanes. Since Wilds Parkway is 33 feet wide (face-of-curb to face-of-curb),
we recommend 1.5-foot gutters on each side, a 7.5-foot parking lane, one II-foot driving
lane (adjacent to the parking lane) and one 11.5-foot driving lane. This will eliminate the
need for a motorist to cross over the double yellow line when traveling
westbound/northbound around a parked car. Striping modifications to Wilds Parkway are
shown on Figures' 2 through 4.
Due to the change in roadway characteristics and increase in traffic volumes near both
ends of the corridor and Wilds Ridge, a no parking restriction should be posted along
both sides of Wilds Parkway at the following locations.
. Between CSAH 83 and 300 feet south/east of Wilds Drive
. Between Fox Hollow and first cul-de-sac south of Wilds Ridge
. Between CSAH 82 and Big Horn Pass
. Due to the vertical curves and direct residential access along Wilds Parkway, we
recommend that the no parking restriction should be posted on the south/west side of the
roadway.
All-Way Stop Control
Several requests have recently been made for all-way stop control at the intersection of Wilds
Parkway and Wood Duck Trail to reduce speeds through the neighborhood. As part of this
study, the need for all-way stop control at this intersection was evaluated. According to the
Minnesota Manual on Uniform Traffic Control Devices, multi-way stop control can be used as a
safety measure at interseCtions where traffic volumes on the mainline (Wilds Parkway) are equal
to the intersecting street (Wood Duck Trail).
According to the Manual, the minimum volume criteria for multi-way stop control installation is
summarized below:
. The minimum vehicular volume entering the intersection on the major street (total of
both approaches) must total 300 vehicles per hour, for eight hours of an average day.

. The minimum vehicular, pedestrian, and bicycle volume entering the intersection on the
minor street (total of both approaches) must total 200 vehicles per hour, for the same
eight hours of an average day. In addition, there needs to be at least 30 seconds of delay
per vehicle on the minor street during the highest hour.
Current traffic volumes and delay on the major and minor street approaches are well below the
minimum requirement for the installation of multi-way stop control. In addition, there is a 70/30
split for mainline/side-street volumes entering the intersection. The installation of unwarranted
stop signs will increase .the mainline delay, since all motorists on Wilds Parkway would be
required to stop at Wood Duck Trail. In addition, recent studies have identified an average
compliance of 23 percent for unwarranted all-way stop controlled intersections.
The Manual also states that stop signs should not be installed for speed control. Speeds on other
segments of the corridor may actually increase as motorists become frustrated with stopping at
an intersection with very little cross traffic, increasing their speeds as they leave the intersection.
In addition, it increases the potential for rear-end crashes as motorists on Wilds Parkway do not
expect to stop at this intersection. As previously stated, travel speeds are currently high on Wilds
Parkway. However, results of a neighborhood speed study often identify that the majority of
motorists violating the speed limit are visitors of, or residents currently living in the
neighborhood.
Based on this information, all-way stop control is not recommended at the intersection of Wilds
Parkway and Wood Duck Trail.
Pedestrian Crossing at Wilds Park
Neighborhood concerns have also been raised involving the need for a pedestrian crossing along
Wilds Parkway. After a review of the neighborhood street network was completed, we
recommend that the crosswalk for Wilds Park be located on the north/west side of the driveway
entrance to the park. This crosswalk location provides the best access to the park from both
directions. Also, putting the crossing adjacent to the park should increase the awareness of
drivers of the potential for pedestrian crossings. The crosswalk should be a "zebra" style
crosswalk. Pedestrian crossing signs (WI1-2: 30"x30") should be placed 250 feet prior to the
crossing and at the crosswalk itself. Down arrows (W 16-7p) should also be placed at the
crosswalk.
A review of the construction plans indicates that adequate stopping sight distance would be
available at the proposed crosswalk location. It is important to note, however, that the vertical
grades are quite steep.
