PLANNING REPORT
TO: Kimberl Kamper / Kris Danielson
FROM: Daniel Licht
DATE: Februar 27, 2002
RE: Oak Park Hei — Hi School Stadium; Plannin Commission
Recommendations
FILE NO: 798.02 — 02.01
BACKGROUND
The Plannin Commission held a public hearin on Februar 21, 2002 to consider the
application of ISD 834 to allow construction of a stadium at the Stillwater Area Hi
School site. As outlined in the Plannin Report from our office dated Februar 14,
2002, the application re the followin approvals:
rovals:
1. CUP amendment to expand the hi school use, which is a conditional use Within
the 0 District.
2. CUP to allow construction of li poles to a hei of 90 feet and for* fixtures
without a 90-de cutoff.
3. Variance to allow construction of the bleachers to a hei g reater than 16 feet.
Followin staff presentations, public comment, and comment from the applicant, the
Plannin Commission closed the public hearin and subse reviewed the issues
and recommended conditions of approval. The Plannin Commission continued their
meetin to March 4, 2002 at 7:OOPM to allow staff to revise the proposed conditions and
for the applicant to provide additional information re traffic mana
ANALYSIS
Public Hearin Testimon was heard from three individuals durin the public hearin
concernin the followin issues:
r
1. There was a question as to whether the multiple uses of the football field, soccer
field, and track were included in the original CUP approval. The 1991 concept
p
plan for the high school campus identified this area for all three uses and
illustrated the location of the bleachers.
2. The height of the light poles was raised as an aesthetic issue. The applicant's
lighting engineer addressed this issue saying that using lower poles for
illuminating the field would result in more horizontal glare and create difficulties
with meeting the Zoning Ordinance limits on light at the, property lines.
3. One person asked what the justification was for granting a variance. Section
401.04.A of the Zoning Ordinance outlines the criteria the Planning Commission
and City Council must consider for variance requests. Variances are only to be
approved when a finding is made that an undue hardship exists which makes
conformance with the regulation unreasonable. The finding for undue hardship
must be unique to the property or structure in question and may not be based
upon cost. In this case, the purpose of the bleachers, to provide seating capacity
and views of the playing field may be cited as features unique to these types of
structure and that conforming to the 16 -foot high limit would create an undue
hardship.
Traffic. In addition to the issues above, the Planning Commission gave considerable
attention to traffic issues. Many of the recommended conditions related to potential
traffic impacts the use may create. The recommendation from Staff is that the
applicant should address all of these issues as part of a comprehensive "Event Traffic
Management Plan ". Staffs expectation is that the traffic management plan would
establish minimum standards for the applicant to meet in utilizing their site. As the plan
is implemented, changes or additional measures to improve traffic management may
arise that were not initially considered. To address such an opportunity, the traffic
management plan may outline procedures for modifications, which would be subject to
review and approval by City Staff. An administrative procedure would avoid the need
for the applicant to seek an amendment of their permit and allow more flexible
implementation of the plan to ensure effective traffic management.
The minimum elements of the Event Traffic Management Plan should include:
1. Fee Parking plans.
2. Incentive plans for the shuttle or offsite- parking plan.
3. Plan for deterring parking in adjacent or neighboring lands.
4. Plans for. traffic control going into and out of the site
including shuttle service.
5. Plans for marketing the shuttle or offsite- parking plan.
6. Plans for starting times of games and events.
Conditions. Based upon the Planning Commission's deliberations, several
modifications were made to the conditions of approval recommended by City Staff.
These are outlined as follows:

Planning Report Recommended Conditions,
February 21, 2002
Condition No. District Response
Historical track meet spectator attendance for the District has
generally fallen in a range of 500 -800 spectators. Approximately 700
spectators attended the District's May 2001 4A Section Meet. Other
regional or conference meets tend to draw spectators in the range of
500 -700 spectators.
2 Approximately 550 studentladult annual passes are sold each Y ear
by the District for admission to all athletic events. No statistical
information is compiled by the District on actual use of the p asses.
However, Sherm Danielson, the District's Activities Director,
estimates that approximately 300 passes may be used at the
District's annual homecoming football game. Applying David
Braslau's projection of 3 persons /vehicle, this would reflect a
possible need for up to an additional 100 parking spaces —all of
which the District would intend to be addressed through offsite
parking- shuttle arrangements.
3 This condition is acceptable to the District.
4 The District requests that this condition be deleted. Use of the
District's high school fields, including the Stadium field and track
surface, current) extends to various times of the day and evening
Y Y g
for both intra and extra curricular activities and events.
5 This condition is acceptable to the District provided that it is limited
only to light meter testing to assure compliance with Sections
401.15.B.7(d) and (e) of the Zoning Code.

6 The District requests that this condition be deleted. The District, the
Ci ty and the community hare an interest in a lighted stadium. A
tY
deadline on construction of lighting improvements, which is
anticipated not to become a factor, may have the effect of eliminating
the District's stadium - related events. This result is both contrary to
the desires of all concerned, but is additionally unnecessary due to
existing study results.
7 See attached supplemental analysis from David Braslau Associates,,
Inc. The sound system limiter should enable the District to preset
sound levels as to not exceed MPCA L50 along the District's
boundary.
3
8 This condition is acceptable to the District,. See response to
Condition No. 7 above.
9 This condition is acceptable to the District,. Current stadium lighting
and arkin lot lighting is expected to exceed necessary lighting
p g g g ex p
requirements for pedestrian walkway traffic. However, the District
proposes placement of spectator /security floodlighting on each of the
northerly light poles, as well as on the underside of the press box, to
cast additional lighting on area walkway areas. See attached
Spectator /Security Liahtinq Plans,
10 This condition is acceptable to the District, provided that anv
requirement for review and approval by Police Chief should be
deleted. This would not preclude Police Chief review, but would not
place the District or the City in the position of affirmatively requiring it
for every event.
11
The District requests that this condition be deleted,. The .District
currently has an emergency procedures handbook covering all
District activities —as to which staff and administrators are already
trained. Two g ates will be available for emergency egress from the
general Stadium area, and open areas are designed to the north and
south of the bleachers for emergency egress from the bleacher area.
The District is not. currently subject to external approval requirements
for any of its emergency procedures. The District is not opposed to
development of an emergency evacuation plan, but feels City
oversight is both unnecessary, and may create emergency
procedures inconsistent with existing District procedures.

12 Satellite toilets furnished for use at the Stadium will either be cabled
to existing fencing or to anchor bolts installed in concrete staging
area, based upon recommendations provided by the District's current
satellite toilet supplier, Port -a -Pot Sanitation.
13 This condition is acceptable to the District, subiect to removal of the
requirement for Citv review and approval. Section 401.15.G of the
Zoning Code already prescribes the application procedures for
qualifying signage. Any further City review /approval requirement (to
the extent contemplated under the Planning Report should be
unnecessary).
14 The District requests that this condition be deleted. There is no plan
to replace the existing scoreboard at the Stadium site. This condition
is unnecessary.
15 This condition is acceptable to the District.
16 This condition is acceptable to the District.
17 The District is continuing to await receipt of further comments, if any,
from the City's Engineer to the Parking and Traffic Assessment
Study,
18 This condition is acceptable to the District.
19 The District requests that this condition be deleted. The District has
no present intention to charge parking fees, but prefers to reserve
the right to do so. The Planning staff's concern is presumably based
upon potential traffic impacts resulting from fee collection at entrance
gates. The District views this as an issue relating to how parking fees
might be collected —not whether they should be collected. This
condition could, for example, prohibit the use of mandatory prepaid
parking fees as a parking lot management tool for encouraging use
of offsite parking lot shuttle systems. Such a system should have no
negative traffic impact.
20 The District requests that this condition be deleted. The District has
targeted 5:00 p.m. as the start time for high attendance daylight
events (e.g., football games) that would normally be held during the
evening; however, the District is also subject to waning daylight
hours as the season progresses, as well as the impact of daylights
savings time. A rigid minimum start time could result in games
extending into darkness hours to the detriment of the event, and the
security and safety of players and spectators.

22 The District requests that this condition be deleted,. Material and
color selection will be dependent on the District's vendor selection
through the statutory public bidding process. The District is not
legally able to guaranty specific material or color selections.
23 This condition is acceptable to the District. The District proposes that
the Conditional Use Permit simply require the District to maintain an
off -site p arking plan acceptable to a designated representative of the
District. The District foresees periodic modification to the plan as it
experiments with various off - site parking management strategies.

RE: Stillwater Area High School Stadium - LIO and L50 Sound Levels
In its ing ` g Report for the High School Stadium, tie City has requested a 't 'onal review on .
projected sotmd levels, Wmifically with respect to the L50 standard. The Sound-imU�,ct .
Assessment 4- m4uat3ed only the L10 standard. and the NIPCA have noted that the stadium nmst
also oomply with► the L50 standard-
Mirrimul sound levels are associated with the sound amplification system The souad:system is
not int ded•to *,au v.-, continuous m usic throughout the fie, and is therefor unlikely to bb in
use fcyr half of the time_ The L50 or median sound level refers to the level, wbich is
exceeded half or 50% of the time. From data associated with outdoor concerts, the L50 limml is
r�orrnall�r 5 dBA below the L10 level. Since the sound system will be used for speech irather than
music, it will not be in use for some of the thne. Therefore, it can be expected that the L50 level
krill be more than 5 dBA below the L10 level. Since the L50 standard is 5 dBA lower than the
LIO standard., the L50 level is not likely to be as critical as the L10 level. This can perbaps be
most easily demonstrated in the table below.
Noiso Metric Est. Max Level Daytime Standard Level re Standard
LID 59 dBA 65 dBA - 6 dBA,
L50 52 dBA 60 dBA - 8 dBA
As suggested in the table, the L50 level is likely to be further below the L50 standard tb= the
L10 level. Tlierefom, based upon the sound asewment, it can be concluded thatneithiz the L10 j
nor the L50 are Uely to exceed the daytime noise standards. If games are held at night, and
extend past the 10:00 pm period that begins the nighttime period, sound levels wall have to be
reduced sufficiently too ensure that the nighttime standards are also achieved.
Since it -is possible to electronically limit the sound power level of the loudspeakers, a.60 dBA
limit at the nearest m idential property Iine can be set to ensure that both the L10 and the L50
standferds will not be exceeded.

MEMORANDUM ENCLOSURE 4

To: Dennis Postler FEB 2 0 2002
Fr om: Bryant F1cek OL
Subject: Stillwater Area High School Stadium Improvements
- Review of the Parking and Traffic Assessment
This memorandum discusses the Parking and Traffic Assessment of the Stillwater Area High
School Stadium Improvement prepared by David Braslau Associates, Inc. and Benshoof and
Associates, Inc. Separated into two parts examining the parking analysis and then the traffic
analysis of that assessment, potential concerns are noted for each section. Conclusions are then
provided at the end of this memorandum.
Parking Analysis
The parking analysis uses historical data to identify a peak attendance, which is then used to
estimate the number of vehicles for that peak event. However, based on information in the
conditional use permit, this number includes paid attendance only. Not included in this total are
pep band members, cheerleaders, players, and coaches from the competing teams or students and
p g
adults with season passes. Others that may have also been excluded in the historical totals are
personnel needed for emergency services, for security, for parkin purposes, or for ticket and
g p� � �
concession sales. Parking from these people would further increase the demand and need for off -
street parking.
In addition, the parking analysis identifies a high -end range of 1,500 vehicles associated with a
peak event as compared to an identified capacity of 892 spaces at the on -site lot. This ields a
deficiency of 60 y
y 8 spaces, rather than the 532 listed in the report, which affects the number of off -
site spaces needed as well as the number of shuttle buses. Usin g g the la r g er number of 608
vehicles, the two sites owned by the School District (supplying 630 stalls ) could still
accommodate this estimate. The Recreation Center with Lily Lake School su 1 in
( pp Y g 580
spaces) would fall slightly short of the number of spaces needed. Using he r assumptions
g p p
for the shuttle buses, up to 10 buses would be needed to provide adequate transportation from
p q p the
off -site parking lot(s) to the stadium.

N
It is also important to note that attendance for other football games may also exceed capacity of
p g Y p tY
on -site parking and require the need for off -site parking. Based on the existing capacity of 992,
the on -site parking lot could expect to accommodate an attendance of between 2,976 (assuming
3.0 people per vehicle) and 3,472 (assuming 3.5 people per vehicle). For attendance levels at or
above these levels, off -site parking would likely be needed. From the historical attendance,
identified in the analysis, three out of 15 other football games, excluding the yearly peak event,
reached this level, about 20 percent. If the attendance of others (such as players, etc., noted
above) were included and if the on -site parking lot had spaces occupied by vehicles not
associated with the stadium event, such as a conflicting event at the school, the capacity would
be finther reduced, suggesting off- street parking could be needed for more than just the peak
football game each year.
Also noted in the, analysis, attendance at the football games may be affected more by team
performance than school enrollment. Therefore, a competitive team could expect higher
attendance and greater need for off -site parking at games than a non - competitive team.
However, it is never certain whether a team will be competitive. Based upon this and the data
mentioned above, a contingency parking plan to accommodate high attendance outside the peak
event should be available for all football games. This should include items identified in the
study, such as avoiding conflicts with other school events to maximize the capacity of the on -site
parking lot and encouraging ride sharing for all games to increase the occupancy per vehicle. In
addition, it may be necessary to have off -site parking and shuttles available on a `stand -by' basis,
to be used if and when a parking deficiency is identified. The need for this could be determined
with a game -by -game approach examining how well the team is doing, how well the visitor is
doing, and attendance at previous games in the year.
To minimize disruption to the adjacent neighborhoods, on -going communication with the
residents should be a part of any management plan in conjunction with this development. This
would allow residents to discuss any future problems associated with the project and facilitate
solutions. For example, the parking analysis identifies on- street parking in the neighborhoods is
a potential problem that should be minimized with parking management. If the residents are
allowed an outlet to communicate with the school, either through the School District or the City,
the success or failure of this aspect of the management plan could be identified. In addition,
future discussions could identify other unseen problems and help to determine solutions.

Traffic Analysis
In the traffic analysis, the volumes for the intersections of 5 8th Street/Neal Avenue and Trunk
Highway 5/5 8th Street are presented after the stadium g enerated traffic is included, without
separate tables for existing and/or generated traffic volumes alone. This prevents a quick review
of the existing conditions at the intersections as well as the opportunity to examine the generated
traffic in the intersections separately from other traffic.
The traffic analysis identifies several assumptions to ensure a worst -case scenario, such as an
event start time coinciding with the busiest background traffic period and use of all parking
spaces. Some other items to consider for the worst -case traffic analysis are:
• Shuttle bus maneuvers to drop off/pick up patrons before and after games,
• Parents who drop off children before games and pick them up afterwards,
• Vehicles that enter and exit the parking lot after all spaces are full, and
• Potential slowdowns from parking maneuvers inside the parking lot.
As noted earlier in this memorandum, up to ten buses could be running to and from off -site lots.
With the traffic analysis' assumption of 5 roundtrips per hour, this could increase the traffic by
50 vehicles entering the lot and 50 vehicles leaving the lot in one hour. Similarly, each parent
who drops a child off at the game and picks them up afterward would increase the traffic.
Although difficult to quantify, if only one percent of the assumed peak paid attendance is
dropped off and picked up, an additional 45 vehicles would be entering and exiting the parking
lot before and after the game.
Once the parking lot is full, vehicles may still enter the lot and search for a space, only to leave a
few minutes later. Also difficult to quantify, an assumption of five percent of on -site capacity
would translate into an additional 50 vehicles entering and exiting the parking lot, increasing
traffic volumes at the intersections.
As the parking lot fills and/or large platoons of vehicles arrive at the parking lot, the potential for
internal slowdowns increase. Should the internal maneuvers in the parking lot slow, it could
start a chain reaction that would in turn slow vehicles turning into the parking lot and then other
vehicles at the intersections of 58 Street/Neal Avenue and Trunk High 5/58" Street as turn
� y
lane queues increase. This slowing would reduce the levels of service of the intersections
regardless of how efficient the signal is operating. The possibility of internal problems during
the entry of vehicles is of greatest concern due to its potential to cause traffic problems on the
nearby intersections, negating any efficiency of signal operation
Despite these additional concerns, a traffic and parking management plan in place for all football
games could provide adequate traffic operations. This traffic and parking management plan
should provides, at a minimum, a set area for drop -offs and pick -ups, a set route for shuttle
buses, signs to advise motorists on both Trunk Highway 5 and 5 8th Street of a full lot and where
to proceed to additional off -site parking, and parking attendants to direct internal traffic. In
addition, the use of police officers to direct traffic at the two intersections during at least the half
hour before kick -off and the half hour after the game could improve intersection operations.
p p
Police officers would be better able to handle the large platoons of vehicles during these peak
times as well as better able to react to any back -ups within the parking lot.

Conclusions
With the inclusion of parking from players, coaches, cheerleaders, and other non-paying event
attendees, over 600 off -site parking spaces could be needed for the peak stadium event
(historically identified as the Homecoming game). The Parking and Traffic Assessment
identifies sites to accommodate this overflow and notes the need for shuttle buses for this p eak
event. However, depending upon other factors, most notably how the team is performing, other
football games also have the potential to use the capacity of the on -site parking and require
additional off -site parking.
Additional traffic concerns, not noted in the Parking and Traffic Assessment, would likel
increase the expected vehicles at the intersections of 58 Street/Neal Avenue and Trunk
Highway 5/58 Street and could potentially slow traffic. Of greatest concern is the potential for
back -ups within the parking lot creating congestion in the intersections.
A parking and traffic management plan for all football games would decrease the likelihood of
unexpected parking deficiencies and traffic slowdowns at the major intersections. This plan
should include, at a minimum, the items identified in the Parking and Traffic Assessment ( such
as a program to encourage alternate modes of travel to the games), as well as a plan for
communication with the surrounding neighborhoods to help recognize and prevent future
problems. It would also be beneficial to be prepared to use police officers to effectively direct
traffic at the intersections during the peak entry and exit times. Police officers would be better
able to handle the large platoons of vehicles during these times as well as react appropriately to
back -ups within the parking lot than would the traffic signals at the intersections. With a arkin
p g
and traffic management plan ready for all football games, the decisions on which aspects to
implement could be determined on a game -by -game basis depending on factors such as how well
the team is doing, how well the visiting team is doing, and attendance at previous games in the
Year.
