6 El Toro High School Bleacher and Lighting Improvement Project Parking/Traffic Management Plan This report contains the parking management plan for the El Toro High School Bleacher and Lighting Improvement project. The proposed project is located at the existing El Toro High School in the City of Lake Forest. El Toro High School is located at Toledo Way. The proposed project includes the construction of bleachers totaling 4,000 seats and lighting improvements at the existing high school athletic field. The El Toro High School Bleacher and Lighting Improvement Traffic Impact Analysis (Kunzman Associates, Inc., June 25, 2012) concluded that overflow parking would be necessary for high capacity events. The purpose of this report is to provide a parking management plan that details the overflow parking areas and how best to access them. The report also provides recommendations to minimize traffic and parking impacts to the surrounding community. It should be noted that this report is intended to be a living document. The proposed Parking Management Team will have the authority to make adjustments to the management strategies as needed to provide an effective program. Although this is a technical report, every effort has been made to write the report clearly and concisely. To assist the reader with those terms unique to transportation engineering, a glossary of terms is provided within Appendix A.

7 I. Parking Demand Levels A. Parking Supply Table 1 summarizes the on site and off site parking supply. Figure 1 shows the project location map and surrounding neighborhoods. On Site: The project site currently provides 693 on site parking spaces. The proposed project will reconfigure the small parking lot on the north side of the project site, resulting in the loss of nine parking spaces for a total of 684 marked parking spaces. The hard court area and grass field at the southeast corner of the project site can accommodate an additional 122 and 315 parking spaces, respectively, based on conceptual parking layouts. La Madera Elementary School provides 73 parking spaces and has been considered on site parking because of its proximity to the project and because it is also managed by the Saddleback Valley Unified School District. On street parking is currently allowed on Toledo Way adjacent to El Toro High School and would provide approximately 16 parking spaces. Parking on Toledo Way has also been categorized as on site because it is primarily used by the high school and does not have any existing parking restrictions. El Toro High School staff currently uses 70 miscellaneous parking spaces throughout the campus. Off Site: Serrano Intermediate School is located off Jeronimo Road and provides 107 parking spaces, which could be accessible via shuttle service. At near capacity events, a variance to allow on street parking on Serrano Road could provide approximately 59 additional parking spaces. B. Parking Demand Ratio A parking demand ratio of 0.30 is considered in this analysis based on the study for the Estancia High School Athletic Stadium Complex project in the City of Costa Mesa (The Planning Center, Initial Study For: Estancia High School Athletic Stadium Complex, February 2002). The Estancia High School Athletic Stadium Complex project counted 601 parked vehicles for a varsity football game between two local schools with an attendance of 2,523. This is a parking demand ratio of 0.24 (601 parked vehicles 2,523 parking spaces = 0.24 parked vehicles per occupied seat). The parking demand ratio of 0.30 used in this analysis includes a factor of safety of 1.25, or 25 percent more than is actually expected. Table 1 also shows the seating capacity supported by the number of parking spaces for each of the parking locations based on the parking demand per seat ratio of C. Parking Demand Levels Three parking demand levels have been identified based on the projected parking required for different anticipated seating thresholds. Table 2 summarizes the parking demand levels. Figure 2 illustrates the parking locations required for each parking demand level. 2

8 1. Level 1 Level 1 parking demands correlate to an anticipated seating threshold of 1,900 to 2,280 seats. Based on the Level 1 parking demands, the following parking locations would provide 684 parking spaces: Marked, on site parking spaces Based on District records, the Level 1 parking management plan is expected for the average football game at approximately 2,100 seats. 2. Level 2 Level 2 parking demands correlate to an anticipated seating threshold of 2,281 to 2,982 seats. The Level 2 parking management plan is likely to be used for football games expected to draw slightly larger than average crowds. Based on the Level 2 parking demands, the following parking locations would provide a total of 895 parking spaces: Marked, on site parking spaces Public, on street parking on Toledo Way La Madera Elementary School On site, unmarked hard court Figure 3 illustrates a conceptual layout of the unmarked hard court parking area, which is projected to yield approximately 122 parking spaces. Visitors should be directed to the hard court parking by a parking attendant. 3. Level 3 Level 3 parking demands correlate to an anticipated seating threshold greater than 2,983 seats. Based on the Level 3 parking demands, the following parking locations would provide a total of 1,280 parking spaces: Marked, on site parking spaces Public, on street parking on Toledo Way La Madera Elementary School On site, unmarked hard court On site, unmarked miscellaneous On site, unmarked grass field Figure 4 illustrates a conceptual parking layout of the unmarked grass field parking area, which is expected to yield approximately 315 parking spaces. Visitors should be directed to the grass field parking by a parking attendant. It should be noted that the access driveway/gate for the grass field overflow parking should be widened to allow two way traffic (minimum of 24 feet) and temporary lighting should be provided. 3

9 Level 3A: If the grass field parking spaces are not available due to weather conditions, a total of 965 parking spaces are provided. The Level 3A parking demands correlate to an anticipated seating threshold of 2,983 to 3,215 seats. Level 3B: A shuttle service to/from Serrano Intermediate School and temporary onstreet parking along Serrano Road would provide an additional 166 parking spaces, for a total of 1,131 parking spaces. This is equal to a parking supply ratio of 0.28 parking spaces per seat, which is greater than the anticipated actual parking demand of 0.24 parking spaces per seat, and still provides a 17% factor of safety over the anticipated actual parking demands. If the grass field parking spaces are not available due to weather conditions, Level 3B parking demands correlate to an anticipated seating threshold of 3,216 seats or more. D. Other Considerations 1. Miscellaneous Parking Spaces The 70 unmarked miscellaneous parking spaces throughout the campus is based upon parking spaces currently used by El Toro High School staff. It is highly recommended that use of these parking spaces continue to be used by District staff only. As noted in the parking demand levels, these parking spaces are only used for above average parking demands (Level 3). When parking vehicles on the high school campus, special consideration should be given to pedestrian safety, emergency access, and overall circulation. 2. Grass Field Parking and Weather Conditions The availability of on site grass field parking is subject to weather conditions. Under wet/muddy conditions, vehicle tires can cut deep grooves into the grass, damaging the field and leading to potential hazards when the field is used for recreational purposes. Therefore, it is recommended that the grass field overflow parking only be used for Level 3 parking demand events under dry conditions. If the grass field is not available, adequate parking supply is still expected to be provided for a full capacity event of 4,000 seats. Under parking demand Level 3B conditions, a total of 1,131 parking spaces are provided. This is equal to a parking supply ratio of 0.28 parking spaces per seat, which is greater than the anticipated actual parking demand of 0.24 parking spaces per seat, and still provides a 17% factor of safety over the anticipated actual parking demands. Using the 0.30 parking spaces per seat ratio, parking demand Level 3B supports a maximum seating capacity of 3,767 seats. This is greater than the maximum recorded varsity football game of 3,583 seats. It should also be noted that the only regular full capacity event, graduation, takes place during the summer when the grass field is likely to be dry. 4

16 II. Parking/Traffic Management Plan This section discusses in detail the parking/traffic management plans for each of the parking demand levels described in Section I. Figure 5 illustrates the project driveways and on site circulation. The existing access restrictions are deemed suitable based on existing performance during school start and end times, but should be observed during high capacity events and modified if needed. Figure 6 illustrates the parking/traffic management plan elements. The parking/traffic management plan elements are color coded corresponding to the parking demand level. A. Level 1 Parking/traffic management plan Level 1 includes placing temporary "No Event Parking, Residents Only" signs at the locations shown in green on Figure 6. Two parking attendants should be provided to help fully utilize the marked parking spaces and direct vehicles to the egress driveways after events. The Level 1 parking/traffic management plan should be implemented when events are expected to reach approximately 85% of the Level 1 parking capacity. Based on a Level 1 maximum supported seating capacity of 2,280 seats, 85% is equal to 1,938 seats. For practical purposes, the Level 1 parking management plan is recommended to be implemented when the anticipated attendance for an event is equal to or greater than 1,900 seats (83.3% of Level 1 parking capacity). B. Level 2 In addition to the Level 1 parking/traffic management elements, signage to the La Madera Elementary School should be placed as shown in orange on Figure 6 and additional parking attendants should be provided. At the beginning of an event, Parking Attendant 1 should direct vehicles into the parking lot located adjacent to Toledo Way. Parking Attendant 2 should direct vehicles into the hard court parking area where Parking Attendant 3 will direct them to the appropriate parking space. Parking Attendant 3 should begin filling the parking spaces near the hard court egress first to maintain visibility with vehicles entering the hard court. Once the hard court parking area is fully occupied, the ingress point should be coned off and Parking Attendants 2 and 3 should direct vehicles to the marked parking spaces in the main parking lot. A "Lot Full" sign should be placed at the entrance of parking areas which are fully occupied. At the end of an event, the ingress driveways should be closed off. Parking Attendant 3 should direct vehicles from the hard court parking area toward the egress on Toledo Way. Parking Attendant 2 should direct vehicles from the main parking lot toward the egress on Ridge Route Drive. 11

17 C. Level 3 In addition to the Levels 1 and 2 parking/traffic management elements, signage indicating the grass field may be used for overflow parking should be placed as shown in red on Figure 6 and an additional parking attendant should be provided for the grass field parking area. As with the hard court parking area, Parking Attendant 5 should begin filling the parking spaces at the opposite corner from the ingress to maintain visibility with vehicles entering the grass field. Level 3 events will require the grass field and miscellaneous parking spaces to be utilized. The miscellaneous parking spaces should be utilized only by District staff and should be filled prior to the event as early as possible. At the end of an event, the ingress driveways should be closed off and parking attendants should direct vehicles towards the appropriate egress driveways. Level 3A: The traffic management plan for Level 3A events is the same as for Level 3, with the only difference being that Level 3A events are limited to a maximum supported seating capacity of 3,215 seats. Level 3B: Figure 7 illustrates the shuttle elements for a Level 3B event when the grass field is unavailable. The District should also obtain a variance to allow temporary parking on Serrano Road (see Figure 2 for exact location). D. Parking/Traffic Management Tools 1. Public Parking Information The District should distribute information to students and parents regarding the available parking locations for large capacity events, including a flyer similar to Figure 2 which depicts the overflow parking locations. The information should be distributed with "back to school" information packets and made available on the District/High School website. 2. Calendar of Events A calendar of the football game schedule and other major events should be distributed at the beginning of each school year to the Orange County Sheriff Department representative and the City of Lake Forest Public Works director. The calendar should be posted on the District/High School website for informational purposes. The calendar should ensure that no two major events at the high school coincide with each other. 3. Timing The parking/traffic management plan signage, parking attendants, and additional elements should be in place approximately one hour before an event until 30 minutes after an event. 12

18 4. Parking Attendants Parking attendants should be equipped with a method of communication (e.g., "walkie talkies" or cell phones) so they can monitor locations with available parking. Once a parking area is filled, the parking attendants should advise each other and direct vehicles elsewhere. A "Lot Full" sign should be placed at the fully occupied parking lot entrances. Parking attendants should remain in the parking areas throughout the event to help direct vehicles to open parking spaces or to off site locations, as necessary. The parking attendants should also be equipped with fluorescent vests and traffic batons to help direct vehicles. These items will be especially useful after events as daylight fades. Not every individual parking space must be marked, but traffic cones, tape, or other method of marking key points should be used to guide parking attendants with the hard court and grass field parking layouts. 5. Temporary Static Message Signs Table 3 shows a summary list of the static message signs required based on the parking/traffic management plan outlined in this report. Temporary message signs are required to guide traffic to off site parking locations and to warn of resident only parking areas. The static message signs should be placed as shown on Figures Parking Management Team The creation of a Parking Management Team is vital to the success of the parking and traffic management plan. The team should consist of representatives from the Saddleback Valley Unified School District, the City of Lake Forest Public Works Department, and the Orange County Sheriff Department. The Parking Management Team should meet at least once after the first major event and then as needed to review the effectiveness of the parking management plan and make adjustments as necessary. It should be noted that this report is intended to be a living document. The Parking Management Team will have the authority to make adjustments to the parking and management strategies as needed to provide an effective program. The District should designate one representative as the Parking Management Team Manager to facilitate the parking/traffic management plan and coordinate efforts among all involved parties. The Manager should maintain records of all equipment and be responsible for their storage and accessibility. The Manager should also coordinate records of parking occupancy and utilization for key events. At a minimum, it should be recorded when and which parking areas become fully occupied and the number of tickets sold for the event. The Manager should be the District's primary point of contact for any issues concerning event traffic and parking. 13

19 7. Shuttle Service Shuttle service is required for Level 3B parking conditions, when the grass field is unavailable due to weather conditions. Directional signs from El Toro High School to Serrano Intermediate School should be placed as shown on Figure 7. From Serrano Intermediate School, the shuttle service route will exit right (southeast) on Jeronimo Road, turn left (northeast) at Ridge Route Drive, turn right (southeast) on Serrano Road, and enter the project site from Serrano Road. A parking attendant is recommended at Serrano Intermediate School to help direct patrons to the shuttle pick up area. Shuttle service is estimated to take approximately 3 5 minutes to travel from Serrano Intermediate School to El Toro High School along the route shown on Figure 7. Two shuttles should begin running one hour before an event until at least one hour after the event and/or there are no more passengers in the pick up area at El Toro High School. 8. Residential Neighborhood Signage and Parking Restrictions In addition to the "No Event Parking Residents Only" signs, the District may coordinate with the surrounding neighborhoods for additional parking management strategies. As necessary, the District should utilize volunteers from booster clubs, athletes, parents, and police explorers to provide additional event attendants at the residential neighborhood entrances most likely to be affected by event parking. Non police volunteers do not have the authority to close public roads, but their presence at restricted parking locations would emphasize the parking restrictions and they may assist with directing vehicles to designated event parking areas. In addition to volunteer duties, safety precautions should be emphasized above all and clearly explained prior to each event. 9. Orange County Sheriff The District should coordinate periodically with the Orange County Sheriff to ensure public safety and effective enforcement of traffic and parking codes. 10. California MUTCD Any future temporary traffic controls or lane closures by the Orange County Sheriff within the public right of way should adhere to the standards and guidelines in "Part 6 Temporary Traffic Control" of the latest California Manual on Uniform Traffic Control Devices (CA MUTCD). 14
