HomeMy WebLinkAboutDevelopment Application - Supplemental Information1. Introduction. DEVELOPMENT APPLICATION CONDITIONAL USE PERMIT ADDENDUM Stillwater School District, Independent School District No. 834 (the "District ") hereby applies for a conditional use permit amending that original Conditional Use Permit issued by the City of Oak Park Heights (the "City ") on December 10, 1991, as the same has been amended from time to time, with respect to the Stillwater Area High School (the "High School") site located at 5701 Stillwater Boulevard North, Oak Park Heights, Minnesota (the "Property"). This application (this "Application) is submitted for the purpose of obtaining supplemental approval for the construction of certain additional improvements (the "Stadium Improvements ") to the stadium /playing field area (the "Stadium ") currently located on the Property. The Stadium was schematically designed as part of the original construction documents for the high school improvements in 1991. The playing field and track were constructed at the same time as the high school building in 1991 with the anticipation that the remaining Stadium Improvements would be constructed at a later date. Prior to January 1, 2002, Miller Stadium, located at Stillwater Junior High School, 523 West Marsh Street, Stillwater, Minnesota, has been used to accommodate the athletic activities of the High School. As of January 1, 2002, the High School is no longer able to use Miller Stadium because the existing bleachers at Miller Stadium are no longer in compliance with applicable Minnesota safety regulations. As a result of the foregoing, the District needs to complete the construction of the Stadium. Unfortunately, until recently, the District lacked adequate funding to undertake this project. The District has now identified funding sources for at least a portion of the project, and remains hopeful that it will eventually be able to accumulate funding for the entire project. Time is limited, however. The first soccer and football games at the High School are scheduled to commence during the last week of August 2002. Taking into account the need to comply with applicable public bidding requirements and the time required to commence and complete construction of the remaining Stadium Improvements, the District must advertise for bids soon in order to assure students, parents and the affected community of the District's ability to furnish a home stadium facility for the 2002 -2003 school year. In connection with the foregoing, the District notes that its application for a conditional use permit in this matter was previously submitted to, and rejected by, the City's planning department due to a request by that department for submission of various additional documents and/or other information. At that time, the next available date for final hearing by the city council for the City (the "City Council") was at its previously scheduled February 26, 2002 meeting. In an effort to timely comply with the City's filing requirements applicable to the February 26, 2002 hearing date, the District attended a staff meeting held with the City's planning department staff and other representatives for 796435 -4 1 the purposes of identifying any remaining submission requirements. Following that meeting, the District was further advised that subsequent submission of its application may be automatically delayed for consideration by the City Council until the council meeting currently scheduled for March 12, 2002. This Application has been compiled and submitted in response to the requirements established at the earlier staff meeting, and has been filed in compliance with the filing requirements originally applicable to the February 26, 2002 City Council hearing date. Due to existing time exigencies, the District respectfully requests accelerated approval of this Application by the City at its February 26, 2002 City Council hearing date, or otherwise as soon as possible thereafter, it being understood that any delay in approval by the City to the March 12, 2002 City Council meeting may further jeopardize the District's ability to timely complete the Stadium Improvements in time for use in connection with the District's Fall 2002 soccer /football schedule, all to the detriment of the District and the affected students, parents and general community. 2. Project Summary. In addition to all other improvements described in the documents submitted with this Application, the proposed Stadium Improvements principally include the following: (a) Home Grandstand (providing seating for 3,418 persons (based on an 18" per person seating design capacity), or seating for 2,849 persons (based upon a 22" per person seat width standard specified in City of Oak Park Heights Zoning Code, Revised 2000 (the "Code ")); 796435 -4 (b) Visitor Bleacher (providing seating for 1,284 persons (based on an 18" per person seating design capacity), or seating for 1,051 persons (based upon a 22" per person seat width standard specified in the Code)); Stadium Lighting System (including four 90 -foot high poles with hooded /shielded fixtures to reduce spill from reaching the properties south of the Stadium and to provide consistent light levels over playing field (c) (0 (g) area) . , (d) Sound System (consisting of speakers mounted on the press box roof (home side) and on the Stadium light poles (visitor's side)); (e) Spectator Entrance (from the existing parking lot north of the existing running track); Ticketing Area (consisting of fencing and gate ticketing areas); Home/Visitor Spectator Paths (consisting of home /visitor spectator separation via fencing and paved walks); and (h) Press Box- Prefabricated Modular Building (measuring 60' long by 8' wide with a photo platform on the press box roof). 2 3. Limited Impact of Stadium Use. It is reasonable to expect use of the Stadium by the District for a variety of events and other purposes, including without limitation Fall varsity and junior varsity home football games and soccer games and Spring home track and field events. With the possible exception of the annual varsity homecoming football game, however, virtually all other Stadium use is currently anticipated to be at levels causing negligible impact on the Oak Park Heights community. In this regard, it is important to note that Fall varsity home football games, excluding the homecoming game, have historically attracted total attendance in ranges at or well below 3,000 spectators. Non - football events generally attract substantially lower attendance figures, with many occurring at times of the day or year where there is little or no need for stadium lighting. Consequently, most of the understandable community concerns with respect to the Stadium are anticipated to be limited primarily to the annual varsity homecoming football game, where historical attendance figures have ranged in recent years from a low of 3,645 spectators to a high of 4,464 spectators. Notwithstanding this limited potential impact, the Stadium Improvements, including without limitation the north -south geographical alignment of the Stadium itself, have been designed at a level commensurate with such annual peak use and with a focus on minimizing any adverse community impact. For additional information regarding projected Stadium uses, please see attached Exhibit H to this Application, Miller Stadium Main Events 2001. For additional information regarding historical varsity football attendance, please see attached Exhibit I to this Application, Football Attendance /Soccer Attendance 1 997 -2001. 4. Possible Delayed Phase -in of Stadium Lighting. Due to funding availability issues, and as more fully discussed below, the District is considering possible delayed phase -in of construction of Stadium Improvements consisting of Stadium lighting. While this Application seeks approval of construction and use of Stadium lighting, as part of the Stadium Improvements and as more fully detailed in this Application and the documentary enclosures submitted herewith, it additionally seeks approval the Stadium Improvements, on the basis that construction of Stadium lighting may be delayed and that use of the Stadium may occur without Stadium lighting until such time as adequate funding becomes available. As such, and in anticipation of the possibility that the initial construction of the Stadium Improvements may exclude Stadium lighting, this Application assumes possible rescheduling of events typically conducted during evening hours (e.g., Fall varsity football games) such that they may be held earlier in the day and without the need for artificial Stadium lighting. Certain documents supporting this Application, such as the Parking and Traffic Assessment, incorporate assumptions of possible early scheduling of such evening events. 5. Public Meeting. On January 2, 2002, the District held a public meeting, which was earlier scheduled and noticed to members of the community, to solicit questions and comments to the proposed Stadium Improvements. For a collection of the minutes to this public 796435 -4 3 meeting, please see attached Exhibit J to this Application, Minutes of Neighborhood Meeting. 6. Parking. Existing parking at the High School is presently adequate for stadium event use and in full compliance with applicable zoning requirements issued by the City. Inclusive of additional parking to be provided for event purposes by restriping designated bus lanes located on the Property, the Property currently includes a total of 992 parking spaces. Section 401.15.F.9.b of the Code establishes a requirement for one parking stall for every eight seats of stadium seating. Assuming a proposed stadium seating count of 3,900 seats (based upon a 22" per person seat width standard specified in the Code), the Code requires the provision of not more than 488 parking stalls in connection with the currently proposed Stadium Improvements, leaving up to 504 parking spaces for use by the District for non - stadium event purposes, if any (it being understood that the District has no intention to schedule significant non - stadium events which would coincide with such major stadium events as periodic High School Fall football games). As previously noted, and notwithstanding the 22" per person seat width standard established in the Code, the Stadium Improvements contemplate a "design capacity" of 4,702 seats (based upon an 18" per person seat width "design standard "). Assuming application of the Code's 1:8 ratio (parking stalls to stadium seats) to this design capacity, the Code would require the provision of not more than 588 parking stalls in connection with the currently proposed Stadium Improvements, leaving up to 404 parking spaces for use by the District for non - stadium event purposes, if any. As a result of the foregoing, regardless of whether the Stadium seating count is based upon the Code's 22" standard or the 18" design standard, the proposed Stadium Improvements are in full compliance with the parking requirements set forth in the Code. Notwithstanding such compliance, and in instances where the District anticipates significant Stadium attendance (principally in the case of the varsity homecoming football game), or competing High School stadium and non - stadium events, whereby available parking on the Property may be insufficient to support such use, the District intends to provide parking shuttle service from other District -owned or third party -owned properties for the convenience and enjoyment of the spectators /attendees and for the benefit of the community. With access to an existing fleet of approximately seventy buses under contract with the District, and with experience in transporting approximately 8,000 District -wide students on a daily basis, such a shuttle service is well within the District's existing resources and capabilities. The District additionally intends to evaluate and implement, as appropriate, various parking management strategies which may include, among others, increased parking lot signage, ride share promotions, etc. For additional information regarding Stadium event parking, please see attached Exhibit K to this Application, Parking and Traffic Assessment. 7. Traffic. The design of the High School campus includes provision for accepting and dispersing up to 992 vehicles onto 58th Street and Trunk Highway 5. In this regard, 796435-4 4 stadium event traffic can be admitted and disbursed through three different ingress /egress driveways serving the property: (i) two driveways located on 5 8th Street; and (ii) one driveway located on Trunk Highway 5. Small Stadium events would generally produce a traffic volume reasonably comparable to that currently involved with activities conducted in the auditorium or gym. At a larger event, like a Friday night football game, the District anticipates, based on its experience at Miller Stadium and on the Parking and Traffic Assessment, dated January 27, 2002, prepared by David Braslau Associates, Inc. and Benshoof and Associates, Inc., that the majority of vehicles enter the parking lot 45 -60 minutes before game time and exit the lot 30 minutes after the game. Traffic controls presently in place should adequately handle this traffic volume even in the case of the annual varsity homecoming football game. The District additionally intends to evaluate and implement, as appropriate, various traffic management strategies which may include, among others, possible parking lot attendants, off-duty police officer traffic direction, etc. For additional information regarding traffic volume, please see attached Exhibit K, Parking and Traffic Assessment. 8. High School Enrollment Projections. Modest High School enrollment increases and declines are currently projected for 2002 and 2003, respectively. Projected net growth over 2001 (66 students in 2002 and 35 students in 2003), is comparatively negligible. Assuming a correlation between enrollment and attendance at Stadium events, any enrollment- related impact on Stadium attendance would be comparatively nominal. In actual fact, historical attendance information for Miller Stadium, as compared to historical enrollment information for the District, demonstrates that no such correlation actually exists. From 1997 through 1999, the High School posted a net enrollment increase of 134 students. By comparison, aggregate attendance at varsity home football games over that same period have posted a net decline of 2,588 spectators. High School enrollment is anticipated to have little or no effect on either Stadium parking or traffic issues. Consequently, overall student enrollment fluctuations are immaterial to this Application. For additional information regarding historical Miller Stadium attendance, please see attached Exhibit I to this Application, Football Attendance /Soccer Attendance 1997-2001. For additional information regarding historical and projected High School enrollment, please see attached Exhibit L to this Application, Stillwater Area High School Enrollment. For additional information regarding the impact of High School enrollment on Stadium event parking and traffic issues, please see attached Exhibit K to this Application, Parking and Traffic Assessment. 9. Sound (Public Address) System. The actual sound system to be incorporated into this project will, of course, be acquired through the public bidding process. However, product literature describing for illustrative purposes a sound system comparable to those currently available in the market, and similar to that which the District intends to install as part of the Stadium Improvements, has been enclosed with this Application. For the purpose of reducing decibel levels and undesirable noise from being directed to properties located to the south of the Stadium, speakers will be directionally located and positioned on the underside of 796435 -4 5 the press box roof (home side) and on the Stadium light poles (visitor's side). As presently designed, the sound impact of the speakers on individual residences most closely located to the Stadium is projected to be well within applicable state noise standards. In the event construction of Stadium lighting is deferred pending funding availability, alternative temporary mounting of the visitor's side speakers may occur, or mounting of such speakers may simply be deferred pending later construction of the Stadium lighting poles. For additional information regarding speaker design, location and configuration, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. For additional information regarding speaker specifications, please see attached Exhibit M, Public Address Sound System Information. For additional information regarding speaker sound impact, please see attached Exhibit N, Sound Impact Assessment. 10. Bleachers. The proposal for the home -side grandstand illustrates a structure measuring 264' long by 22 rows high for a total (net) seating capacity of 3,418 (based upon an 18" per person seat width "design standard "). The front walkway of the bleachers is 5' above finish grade and is accessed via handicap accessible ramp or stairs. The visitor -side bleachers measure 138' long by 15 rows high for a total (net) seating capacity of 1,284 (based upon an 18" per person seat width design standard). The front walkway of the bleachers is 4' above finish grade and is accessed via handicap accessible ramp or stairs. The bleacher is constructed of hot - dipped galvanized steel framing with aluminum extrusions (seat, foot planks). The bleachers are considered "closed - deck" because there are no openings between foot and seat planks. Aluminum riser boards may be colored either black or red to be consistent with high school colors. For additional information regarding bleacher design, location and configuration, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 11. Stadium. Lighting. A four (4) -pole Stadium lighting system is proposed with two poles on either side of each bleacher structure. It has been determined that 90 -foot high poles are necessary to adequately reduce glare and spill to a minimal level (lower poles /fixtures will increase the horizontal glare /spill of the light). The football field will be lighted to an average of 50-foot candles. As previously noted, due to possible funding issues, actual construction of the Stadium lighting may be temporarily deferred. For additional information regarding Stadium lighting design, location and configuration, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 12. Removals. Removals required for the proposed Stadium Improvements will generally involve the removal of selected fencing and pavements, including a portion of the northwest track chute area. In addition, existing trees in the path of the construction will be transplanted rather than removed. Trees outside, but adjacent to, construction limits will be protected with snow fence. 796435 -4 6 13. Spectator Entrance Gate. As mentioned above, future plans call for a concession/ticket/toilet facility at the main entrance into the Stadium. Due to budget issues, the current proposal illustrates dedicated gates for home spectators separated from visitor spectators. The District may place transportable ticket booths at the ticketing area during events. Such booths may be similar to the existing parking lot guard building at the entrance of the High School. For additional information regarding ticketing area design, location and configuration, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 14. Press Box. The press box is constructed as a prefabricated, modular building measuring 60' long by 8' wide. The structure is installed on the steel framing of the home -side bleachers and is accessed from the bleacher step aisles. A photo platform is accessed via a ship's ladder and roof hatch inside the press box. The maintenance -free vinyl siding of the press box comes in earth tone colors to complement the bleacher construction. For additional information regarding press box design, location and configuration, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 15. Trash Receptacles. Several trash receptacles (barrels) will be located around the Stadium and will be cleaned on a regular basis. For additional information regarding trash receptacle location, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 16. Toilet Facilities. Portable satellite units will be provided during events. The number of toilets will be in accordance with projected stadium event attendance. For additional information regarding satellite toilet location, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 17. Fencing. Chain link fencing (8' height) will be re- aligned /provided to secure the site. Similarly, additional fencing (4' height) will be constructed adjacent to the running track to separate spectators from the field of play. Chain link fencing will be installed around the bleacher structures to keep persons from accessing the under -side of the bleachers except to accomplish periodic cleaning. For additional information regarding fencing design, location and configuration, please see the enclosed Plans for Stadium Improvements- Bleachers, Press Box & Lights. 18. Landscaping. The general intent of the landscape plan is to provide replacement (transplanting) of on -site evergreen trees and to restore the grass areas following construction. We will specify that transplanted trees have a one-year warranty to cover the replacement of dead 796435 -4 7 or dying material. For additional information regarding landscaping specifications, please see the enclosed Plans for Stadium. Improvements- Bleachers, Press Box & Lights. 19. Variances.

These improvements will provide bleacher seating for the home team of 3,418 and for the visiting team of 1,284 based on 18" per seat, for a total of 4,702. This assumption, based upon actual data, provides a higher bleacher capacity than the design level of 22" per seat. This assessment assumes that games will be played on a Friday afternoon without stadium lighting so that the games will begin at 5:00 pm and end at approximately 7:00 to 7:30 pm. Thus, inbound traffic flows for the afternoon game, which will occur simultaneously with the beginning of the PM Peak Hour traffic flow, are likely to have the greatest impact on adjacent roadways and intersections. The afternoon game represents worst case traffic impacts associated with the stadium, since background traffic will be higher during this time period. While football games are typically the largest attractor of motor vehicles, the stadium will also be used for soccer (which draws about 10% of football attendance) and other school - related sports and non - sports events. The parking analysis estimates the number of parking spaces required on and off of the High School campus, based upon a Friday football game attendance similar to the peak recorded attendance in 2001. This assessment also makes recommendations for minimizing the parking demand through programs to encourage ride - sharing. Since it is likely that at least some off -site parking will be required, the location and availability of this parking, along with a shuttle system between these areas and the stadium, are discussed. The greatest impact on the adjacent roadway system will occur at the intersection of Stillwater Boulevard (TI-I 5) and 58 Street, and at the intersection of 58 Street and Neal Avenue, the main entrance to the school campus. The analysis of potential impacts on these intersections is based upon the maximum number of vehicles that can be accommodated on the campus. A program will be developed by the School District to limit parking on the campus to available spaces and encourage parking and use of shuttles or walking from off -site parking. Section 2.0 of this assessment reviews available data, including parking capacity on the school campus and previous and expected future attendance at football games. This section also establishes expected spectator demand for a peak event and the number of available parking spaces on campus. Section 3.0 estimates the total parking demand expected for a peak event at the stadium, compares this with available parking on the campus, and identifies off -site parking alternatives and a shuttle system for accommodating this parking demand. Section 4.0 evaluates traffic impacts associated with the stadium improvements and peak attendance at a football game on a Friday afternoon. This section also discusses traffic management on the campus to expedite the flow of vehicles to available parking spaces. Section 5.0 discusses expected impacts from night games at the stadium. Section 6.0 presents a summary of findings and conclusions of the parking and traffic study. Stillwater Area Schools.

Parking capacity on the High School Campus Parking area on the school campus shown in Figure 2.1. The number of spaces in each of these areas, the number of already occupied spaces (based upon a count just before 5:00 pm on Friday, January 18, 2002), and the number assumed to be available for stadium parking by game start at 5:00 pm are shown in Table 2.1. Table 2.1 Parking Spaces Available on Campus for Stadium Event Notes: (1) Includes 8 handicap and 9 short -term spaces (2) Bus corral re- striped to add 45 spaces (3) Includes 10 handicap spaces Based upon a seating capacity of 4,702, available parking spaces for a game (892) are almost double the number required under the City of Oak Park Heights zoning code (588) based upon one space per 8 seats (4,702 = 588). 2.2. Historical and future attendance at football games Data on attendance at football games have been provided by the School District. These are summarized below in Table 2.2. A graphical representation of total attendance by game over time is presented in Figure 2.2. This figure shows a lower attendance in the most recent years at three of the four home games and slightly higher number for the games with the highest attendance. In 2001, the peak attendance was 4,484, although it has been close to this level in past years. Although enrollment is expected to increase in 2002 by approximately 6.5 %, peak attendance has varied by as much as 22% in the past five years and may be affected more by team performance than by school enrollment. Therefore, for purposes of this parking and traffic study, a game attendance of 4,500 will be evaluated. It should be emphasized that this level of attendance will likely occur only once per year, with the other games drawing approximately half as many spectators. It can also be seen in Figure 2.2 that attendance at the remaining three games has decreased over the past five years as enrollment has increased. Stillwater Area Schools.

Expected parking demand Based upon an accepted standard reference on parking (Parking, Weant and Levinson, ENO Foundation 1990), vehicle occupancies of 3.5 persons are common at football games. However, studies have also shown that average occupancies of 3.0 persons per vehicle can occur for professional and college football and concerts. With a peak attendance of 4,500, the parking demand may range from 1,280 vehicles using a 3.5 persons per vehicle occupancy to 1,500 vehicles with a 3.0 persons per vehicle occupancy, with the lower value more likely with a high school football event. Vehicle occupancy will depend upon a number of factors. For example, a count this fall indicated 688 students on morning buses or 31% of the 2,209 students enrolled in 2001. A total of I ,425 students are on the bus route lists. Some of these students may stay on or in the vicinity of the school after class dismissal time (3:02 pm) or they may return home and arrive at the game by car, either alone or with others. 12. On -site parking capacity Estimated on -site parking capacity from Table 2.1 is 892 spaces. Therefore, there will be insufficient capacity provided by school parking alone to meet the expected vehicle demand. Based upon the assumptions above, from 388 to 532 vehicles will have to find parking at off -site locations. 3.3. Off -site parking locations and capacity Three likely alternative parking areas have been identified in the vicinity of the high school where off-site parking may be available. The School District has already contacted the City of Stillwater regarding use of the St. Croix Valley Recreation Center located at 1 675 Market Drive. There are 450 parking stalls on that site. The Stillwater Jr. High School at 523 West Marsh St. contains 500 parking stalls. Lily Lake Elementary School located at 2003 West Willard St. contains 130 stalls. These sites are shown in Figure 3.1. The two sites owned by the School District provide 630 spaces, which could easily accommodate the high estimate of 532 spaces. The Recreation Center with Lily Lake School would provide 580 spaces, which would also be sufficient to accommodate the maximum number of expected vehicles parking off -site. 3.4. Bus shuttle program from off-site locations From 1,358 persons (with 3.5 persons per vehicle) to 1,596 persons (with 3.0 persons per vehicle) may have to be shuttled from off-site locations to the stadium. Assuming buses with a capacity of 40 persons, from 34 to 40 bus trips will be required. Assuming that the round trip from the off -site parking location to the stadium requires 12 minutes and all of these must occur within one hour, one bus will be able to make 5 round trips in an hour and 8 buses would be needed to provide this service. The closer the off-site parking, the fewer buses will be needed to provide adequate shuttle service. Stillwater Area Schools. Page 6 Stillwater Area Hi h School - Stadium Im. rovement Parkin and Traffic Assessment 3.5 Parking Management Since the school has control of events and scheduling at the school, it is possible to limit joint events at the school. Evening events could be scheduled to minimize any potential conflict that could occur on a Friday game night where arriving cars may conflict with departing cars from the stadium. For purposes of the parking and traffic study, it has been assumed that no conflicting events will be scheduled the evening of a football game. A ride - sharing program could encourage both students and adults attending the game to share cars or vans to minimize overall parking demand and reduce the number of off-site alternative parking spaces needed. For expected peak events, it may be helpful to provide advanced notice in the school paper and possibly the local paper regarding the availability of off-site parking and free shuttle service. In addition, issuance of on -site parking permits may help control on -site parking capacity. Signage to indicate that the lot is full and to provide information on alternative parking the shuttle service could also be helpful. On- street parking is prohibited in the residential neighborhood immediately east of the school until 5:00 pm, which should minimize parking in the neighborhood for afternoon games. Signage can be provided in other neighborhoods as needed to restrict parking associated with stadium events. On-street parking on major roadways in the vicinity of the school is not permitted. A combination of information and parking management should ensure adequate parking to meet stadium demand and minimize the need for any on- street parking in the vicinity of the school.

Purpose and Background The purpose of this section is to present the traffic study results for the proposed project. This assessment focuses on the Friday time period between 4 pm and 8 pm in order to analyze the peak entering and exiting traffic conditions. The two major intersections in the area, T.H. 5/5 8 Street and 58 Sty eet/Neal Avenue, have been analyzed relative to traffic operations with a major football event occurring at the stadium. 4.1.1. EXISTING CONDITIONS T.H. 5 is a four -lane, divided roadway with turn lanes and traffic signals at major intersections. The geometries at the T.H. 5l5 8 Street intersection are as follows: • East approach --- one left turn only lane, one left turn/through lane, and one right turn lane • West approach -- one lane shared by left turn, through, and right turn movements e North approach -- two left turn lanes, two through lane, and one right turn lane • South approach W -- one left turn lane, two through lanes, and one right turn lane The T.H. 5/58 Street intersection is controlled by a traffic signal which operates with east/west split phase and north/south protected left turns. 58 Street is a two lane, undivided roadway with turn lanes and a traffic signal at Neal Avenue. The geometries at the 58 Street/Neal Avenue intersection are as follows: O East approach --- one left turn only lane, one through only lane, and one through/right turn lane. • West approach ---- -- one left turn only lane, one left/through lane, and one right turn lane O North approach — one left/through lane and one through/right turn lane i South approach — one left turn lane and one through/right turn lane The 58 Street/Neal Avenue intersection is controlled by a traffic signal, which operates with east/west split phase and north/south permissive phase. Traffic volume data were collected on a Friday between 4:00 pm and 8:00 pm at both intersections on January 18, 2002. While traffic volumes may be slightly higher in the Fall, this is expected to have little impact on intersection performance. Stillwater Area Schools.

Trip Generation Trip generation estimates for the stadium were based on the number of parking spaces available for spectators. It is expected that the worst case scenario for the stadium will involve use of all of the existing parking spaces. Currently there are 992 parking spaces on site as noted above in Table 2.1. The trip generation for the site was based on the following assumptions: • The football game begins a 5:00 pm • All of the 992 parking spaces are used • As noted in Section 2.1, 100 of the parking spaces are occupied at 4:00 pm by students or staff who are involved in other activities • 75 percent of the spaces will be filled during the 4:00 to 5:00 pm hour • 25 percent of the spaces will be filled during the 5:00 to 6:00 pm hour • 25 percent of the spaces will be emptied during the 6:00 to 7:00 pm hour O 75 percent of the spaces will be emptied during the 7:00 to 8:00 pm hour Table 4.1 shows the results of the trip generation estimates. Table 4.1 rfrip Generation Estimate for a Football Event 4.1.2.2. Trip Distribution Trip distribution was based on the central location of the stadium within the school district (see Figure 4.1) and the location of expected spectators. The following trip distribution percentages were for trips generated by the stadium: i 45 percent to /from the north on T.H. 5 O 40 percent to /from the south on T.H. 5 O 15 percent to /from the east on 58 Street Some of the traffic arriving from the south on T.H. 5 is assumed to use the right -in -only access south of 58 Street. Following the game, this access will also be used by some northbound vehicles. A limited number of vehicles are expected to access the site at the entrance to the bus parking lot east of Neal Avenue, since only 15% of traffic is expected to come from the east on 58 Street.

Intersection Traffic Volumes The traffic generated by the proposed stadium was added to the existing volumes, resulting in post - development traffic volumes. Table 402 shows the traffic volumes for a Friday night with a football game at the stadium. EB, WB, NB and SB refer to Eastbound, Westbound, Northbound, and Southbound traffic, respectively. Table 4.2 Friday Turn Movement Volumes at the T.I-I. 5 /58 Street add 58 Street/Neal Avenue Intersections with a Football Game at the Stadium 4.1.3. TRAFFIC ANALYSIS Capacity analyses were performed using the methodologies presented in the Highway Capacity Manual for each of the time periods. Capacity analysis results are presented in terms of level of service (LOS), which range from A to F. Level of service A represents the best intersection operation, with very little delay for each vehicle using the intersection. Level of service F represents the worst intersection operation, with excessive delay. A description of each of these levels of service is included in Appendix A. For analysis purposes, the existing geometries and traffic control were assumed for all time periods. Table 43 presents the capacity analysis results. All intersections will operate at LOS C or better for all time periods, which is considered an acceptable level of service. Some individual movements will operate at an acceptable LOS D, which still permits a stable, but restricted, flow. Therefore, the level of service analysis shows both intersections have adequate capacity to accommodate the expected traffic volumes. Stillwater Area Schools.

Traffic Management With large events such as this, traffic operation difficulties can still occur even if no level of service difficulties are identified. This is due to the very large number of vehicles that will be entering and exiting at the start and end of an event. Some traffic management strategie to help reduce potential traffic operational difficulties include: the use of parking attendants to direct motorists where to park in the most efficient manner; possible signal timing changes to give more time for heavy entering movements before games and exiting movements after games; and use of police officers to direct vehicle and pedestrian traffic after games to help eliminate delays and conflicts due to the high number of exiting vehicles. 5.0 EXPECTED IMPACTS FROM NIGHT GAMES The parking demand for a football game, whether in the afternoon or the evening, is essentially the same and the school can control scheduling of other events at the school to minimize non - football parking demand during games. Similar off -site parking locations as discussed above will also be needed for night games. While parking is prohibited in the residential neighborhood east of the school until 5:00 pm, later parking could occur with a night game. Therefore, additional limitations with appropriate signage may be needed to control parking during night games at the school. Arriving traffic for a game beginning at 7:00 pm will not encounter PM Peak Hour traffic and hence overall volumes at the two critical intersections will be lower. Traffic will exit the school when background traffic is considerably lower than at 7:00 and 8:00 pm. Therefore, after-game traffic impacts are likely to be less than for daytime games. Stillwater Area Schools. Page 13 Stillwater Area Hi _h School - Stadium 1m rovement Parkin and Traffic Assessment 6M SUMMARY OF FINDINGS AND CONCLUSIONS 6.1. Parking demand and analysis The parking analysis has been based upon expected peak attendance at a football game of 4,500, which is only expected to occur once each year. Assuming an average vehicle occupancy of 3.0 to 3.5 persons per vehich , and assuming that some students may remain on campus and that some will use modes other than motor vehicles, a total vehicle parking demand of 1,280 to 1,500 vehicles has been estimated. With only 892 spaces expected to be available for an afternoon game at the school, 388 to 532 vehicles would have to find parking off -site. Shuttle buses would be required to bring persons from remote parking locations to the school. Assuming an average round trip from the remote parking (including passenger loading and unloading) of 12 minutes, eight 40- passenger buses will be needed to provide this service. Similar parking demand is anticipated for both afternoon and nighttime games. For other games and events, parking on the school campus should be adequate. 6.2. Traffic demand and analysis Traffic was analyzed for the period between 4 pm and 8 pm at the intersections of TH 5 and 58 Street, and at 58 Street and Neal Avenue. Assumptions have been made as to the number of vehicles per hour entering or departing the school campus. The distribution of arriving and departing trips is based upon the location of the school within the school district and population distribution within the district. Turning volumes were estimated at each of the two intersections for each hour and intersection capacity was analyzed. Xt has been concluded that all intersections will operate at LOS C for all time periods, although some individual movements may operate at LOS D. Since these are acceptable levels of service, the two intersections will have adequate capacity to accommodate the expected traffic volumes. Traffic impacts from night games are expected to be lower than those analyzed in this assessment. 6.3. Parking and Traffic Management A program to encourage ride - sharing, walking or bicycling to the game could reduce parking and traffic demand, although benefits from such a program cannot be quantified. It may also be useful to issue special parking permits for on -site parking prior to the game, and to provide trained personnel to efficiently direct vehicles to appropriate parking locations. Changes in the signal timing may be helpful in order to give more time for heavy entering and exiting movements before and after games. Use of police officers to direct vehicle and pedestrian traffic after games during the heavy exiting movements will help eliminate delays and conflicts due to the high number of exiting vehicles. Additional signage may be required in adjacent neighborhoods to limit traffic and parking associated with stadium events. y:\jobsl200l jobs\201088\rcports \ stillwate traffic report.doc Stillwater Area Schools. Page 14 Stillwater Area High School - Stadium Improvement Parking and Traffic Assessment APPENDIX A LEVEL OF SERVICE (LOS) DESCRIPTIONS Stillwater Area Schools. Page 15 In order to better understand how the intersections operate from an overall traffic capacity standpoint, capacity analyses were performed using the methodology presented in the Highway Capacity Manual. Capacity analyses determine how well or poorly an intersection is operating. Capacity analysis results are presented in terms of level of service, which is defined in terms of traffic delay at the intersection, and ranges from an A to an F letter grade. • Level of service A corresponds to a free flow condition with motorists virtually unaffected by the intersection control mechanism. For a signalized or an unsignalized intersection, the average delay per vehicle would be approximately 10 seconds or less. • Level of service B represents stable flow with a high degree of freedom, but with some influence from the intersection control device and the traffic volumes. For a signalized intersection, the average delay ranges from 10 to 20 seconds. An unsignalized intersection would have delays ranging from 10 to 15 seconds for this level. ® Level of service C depicts a restricted flow which remains stable, but with significant influence from the intersection control device and the traffic volumes. The general level of comfort and convenience changes noticeably at this level. The delay ranges from 20 to 35 seconds for a signalized intersection and from 15 to 25 seconds for an unsignalized intersection at this level. • Level of service D corresponds to high-density flow in which speed and freedom are significantly restricted. Though traffic flow remains stable, reductions in comfort and convenience are experienced. The control delay for this level is 35 to 55 seconds for a signalized intersection and 25 to 35 seconds for an unsignalized intersection. For most agencies in the Twin Cities area, level of service D represents the minimal acceptable level of service for regular daily operations. • Level of service E represents unstable flow of traffic at or near the capacity of the intersection with poor levels of comfort and convenience. The delay ranges from 55 to 80 seconds for a signalized intersection and from 35 to 50 seconds for an unsignalized intersection at this level. O Level of service F represents forced flow in which the volume of traffic approaching the intersection exceeds the volume that can be served. Characteristics often experienced include: long queues, stop-and-go waves, poor travel times, low comfort and convenience, and increased accident exposure. Delays over 80 seconds for a signalized intersection and over 50 seconds for an unsignalized intersection correspond to this level of service.

The target maximum sound level for spectators in each of the bleachers shown on the stadium layout in Figure 1 is assumed to be 85 dBA which should provide adequate intelligibility with typical background noise from the spectators. Use of the loudspeakers during peak crowd noise periods will limited. This assessment assumes the minimum number of speakers required to provide adequate coverage. However, use of additional speakers to provide coverage of the bleachers can reduce the sound power needed for each of the speakers. Therefore, the off -site sound levels predicted here should represent worst case levels. Sound level predictions are based upon the AcoustaCADD computer model developed by Altec- Lansing, assuming MR115 94A loudspeakers. These should represent worst case sound levels in terms of dispersion away from the bleachers. Section 2.0 of this assessment describes the assumed location and orientation of loudspeakers to ensure adequate coverage of the home and visitor bleachers. Section 3.0 presents estimates of off site sound levels and expected maximum sound levels at the nearest residences. A discussion of these levels relative to state noise standards is included. Section 4.0 discusses the issue of crowd noise and expected off -site sound levels associated with spectators as well as musical groups using the stadium. Stillwater Area Schools.

Home Bleachers Loudspeakers on the home bleachers are assumed to be mounted on top of the press box and oriented downward and to the sides to provide maximum coverage of the bleachers. As noted above, more than one speaker at each location could provide better coverage of the bleachers while at the same time reducing off-site sound levels. Location of the loudspeakers relative to the bleacher layout is shown in Figure 2. Location of the speakers relative to the bleacher cross - section is shown in Figure 3. To ensure a more even coverage of the bleachers, placement of the speaker from 10 to 12 feet above the press box has been assumed. 2.2. Visitor Bleachers Loudspeakers for the visitor bleachers are assumed to be placed on posts either side of the bleachers with the loudspeakers oriented downward and towards the bleachers. An elevation of 35 feet above ground level has been assumed in this analysis. Location of the loudspeakers relative to the bleacher layout is shown in Figure 4. Location of the speakers relative to the bleacher cross- section is shown in Figure 5. Stillwater Area Schools.

Noise Contours Noise contours have been estimated from the stadium sound system (both home and visitor loudspeakers operating simultaneously). The resulting contours are shown in Figure 6. Shown in the contour are the 65 dBA, 75 dBA and 85 dBA contour. The figure shows generally adequate coverage of the bleachers with the design level of 85 dBA and a 65 dBA contour that extends approximately 300 feet south of the bleachers. The contour extends further to the east since the speakers for the visitor bleachers are directed generally towards the bleachers or to the east. Because of the smaller area to be covered, the visitor loudspeakers can be set 10 dBA lower than the home loudspeakers. Thus, orientation of the bleachers and location of the home and visitor bleachers contribute to the containment of sound around the stadium. The state noise standard that is applicable to sound from loudspeakers is the L 10 standard, or the sound level exceeded for more than 6 minutes and less than 30 minutes of any hour. The L10 limit for daytime hours (7 am to 10 pm) is 65 dBA. Therefore, it can be seen that the impact area of levels over the state noise standard is limited to about 300 feet from the stadium. This assumes a well - designed and well - targeted sound system to minimize unwanted sound outside of the bleacher areas. 3.2. Sound Levels at Adjacent Homes Maximum sound levels have also been estimated at individual residences closest to the stadium. These levels are shown in Figure 7. The location of the homes are identified by number in Figure 6. As expected., the highest sound level is predicted for Home 3 which is closest to the stadium. The sound level is generally proportional to the distance of the homes from the stadium. As can be seen in Figure 7, all of the levels are well below the L l O 65 dBA daytime sound level limit for residential land uses. Should lighting be provided for the stadium, the anticipated time for the completion of games is 9:15 to 9:45 pm, so that games are not expected to extend past the 10 pm daytime period. Should games or events extend beyond 10 pm, provisions will have to be made to reduce sound levels by at least 4 dBA. This could be done by using only a portion of the sound system as needed or using a specially designed sound system for these types of events. Stillwater Area Schools. Page 8 3. 4.1.1.1,01.1.1.1.000M Stillwater Area High School - Stadium Improvement Sound Impact Assessment 4.0 EFFECT OF CROWD AND BAND NOISE Worst case noise levels associated with spectators seated in the home team and visitor team bleachers can be approximated using published voice level data and assuming that virtually all of the home spectators in the bleachers shout simultaneously. Assumed peak attendance at a football game is 4,500 persons. With the closest home approximately 600 feet from the bleachers, the maximum predicted crowd level with everyone in the bleachers shouting is 59 dBA, taking into account some directivity of the human voice. This level is similar to the maximum expected level from the sound system and is well below the L10 standard of 65 dBA for sounds that last greater than six minutes of any hour. These levels of voice effort cannot persist for more than several seconds and the time at these levels is likely to total only several minutes during even a high scoring game. Even if combined with simultaneous sound from loudspeakers, the maximum predicted level at the nearest residence is 62 dBA which is still below the 65 dBA. It is unlikely that this will occur for more than a total of several minutes in any game, and this level will only occur one time per year with peak attendance. Three of the four games have approximately one-half as many spectators, so that sound levels will be at least 3 dBA lower than those discussed above. The option of erecting a sound wall or planting a tree buffer will have little if any effect on reducing these sound levels since the sources are dispersed throughout the bleachers and are well above ground level. The crowd noise issue has been reviewed for similar projects with staff of the Minnesota Pollution Control Agency. It has been noted that no violation of the noise standards were ever attributed to crowd noise at outdoor events. The current MPCA position on crowd noise from sporting events is that it is unregulated. Therefore, crowd noise is not likely to exceed any currently established limits on sound level. Bands playing during practice or football games, and Drum and Bugle groups that may use the stadium one time per year, will generate sound levels generally well below those of the sound system or spectators. The maximum sound level with bands marching towards the nearest homes will be well below 65 dBA. and the level will be significantly reduced as band members march away from the homes. Bands seated in bleachers will generally direct their instruments towards the field and minimize sound levels to the south where the nearest homes are located. Therefore, sound levels from the bands on the field or in the bleachers are not likely to exceed MPCA standards and no significant impact from band music is expected because of the proposed stadium. y:\jobs1200I jobs\20 I 0881reports\stillwater noise rcport.doc Stillwater Area Schools.
