The City SEPA responsible Official has determined that this application does not require a SEPA threshold determination because it is categorically exempt. Staff: Stacy MacGregor, Assistant Planner Recommendation: Approval with conditions Request Highline School District is planning to relocate its Aviation High School (AVS) program to a new building it proposes to construct at 9229 East Marginal Way South, parcel number 5422600020. The construction will take place on land leased from the Museum of Flight, a site chosen to take advantage of the adjacent Museum's facilities and King County International Airport. The site is currently vacant; pending approval, the new high school will be a 3 -story, 6,000 square foot building with frontage improvements and associated parking. Future plans include incorporating the school building into a Museum of Flight structure and utilizing the school's parking and facilities to serve the Museum outside of school hours. In May, 2009 a code interpretation determined that the AVS will function as an accessory use to the Museum of Flight. As part of the site development, the high school is requesting aR-8 10% reduction in the number of parking spaces required by the Tukwila Municipal Code (TMC). To justify this request, the applicant provided a Traffic and Parking Analysis dated October 30, 2009 by Heffron Transportation, Inc including a parking proposal.' The proposal would provide parking capacity for 4173 vehicles to include 460 -158 long -term spaces, •• .. • . • : : , and 8itional 15 temporary spaces available outside of bus loading/unloading times. The plans submitted were not reviewed for code compliance but will be reviewed as part of the building permit. The final parking lot lay- out may be different than the lay -out shown on the site plan submitted with this request. All parking stalls and drive - aisles must conform to City standards. The traffic analysis and recommendations provided in the submitted proposal were not reviewed as part of this request for a parking variance.

Under Figure 18 -7 of the Tukwila Municipal Code, high schools are required to provide one parking stall for each staff member plus two stalls for every five students or visitors. To meet code, the project would need to include 192 parking stalls. No more than 30% of the total off - street parking stalls may be designated for compact cars. Since AHS already is operational, the actual parking needs can be determined. Aviation High School opened in 2004 at the Duwamish campus of the South Seattle Community College. In 2007, the school was moved to the former Olympic Middle School site in Des Moines. The parking analysis is based on the existing program's parking demands on June 4, 2009 and is summarized below. Summary of the parking needs for the 2008 -2009 school year: -- 368 students, 72 student parking passes issued, 32 staff members, expected parking need: 104 stalls. -- Peak parking demand during the peak period of 11:00 am to 12:00 pm: 99 vehicles or .27 vehicles per student.2 The peak parking demand is consistent with the expected parking needed taking into account absenteeism. Applying the same peak parking demand rate of .27 vehicles per student to the intended future enrollment of 400 students results in a future peak demand of 108 vehicles. The proposed parking supply of X173 parking spaces Would utilize approximately 6-1-62% of the proposed parking during the peak period, leaving 69-64 spaces unused during typical school -day conditions. The excess parking supply is available for special events. Review Criteria TMC 18.56.140 (B) states the criteria that will be used to evaluate administrative variance from parking standards. A. All shared parking strategies are explored. The parking requirements of the TMC are in excess of the known needs of the proposed use. The Museum of Flight intends to enter into a shared parking agreement with the high school site to allow the Museum to use the school parking lot during Museum events if school demand is not occurring simultaneously. B. On site parking and ride opportunities are fully explored. Highline School District plans to continue providing bus transportation to students living in the District's service area and in nearby districts. King County Metro Transit also serves the site with three routes. Based on the current schedules of the routes and the school day, students could use route 124/174 for morning arrival and afternoon dismissal and routes 154 and 173 for afternoon dismissal. The site design also includes a short-term cell phone waiting lot for student pick -up and visitor parking outside of bus loading times. C. The site is in compliance with the City's commute trip reduction ordinance, or if not an affected employer as defined by the City's ordinance, agrees to become affected. The project is not subject to the requirements of the City's CTR program. However, granting this administrative parking variance will require that the site participate in the City's CTR program. D. The site is at least 300 feet away from a single - family residential zone There is no single - family residential zone within 300 -feet of the subject property. E. A report is submitted providing a basis for less parking and mitigation necessary to offset any negative effects 2 Traffic and Parking Analysis by Heffron Transportation, Inc. dated 10 -30 -2009, page 5.

According to the Heffron report, AVS is expected to generate typical school -day peak parking demand of 108 vehicles. The plan proposes 177 173 parking spaces, an excess of 64 38% from the forecasted typical school -day. Conclusion Based upon the information presented to the City, the reduction of parking on the site by eight percent is warranted. The applicant has provided a parking review, which demonstrates that sufficient parking will be available on the site. Staff' s Recommendation The administrative parking variance should be granted for an 8% reduction in the required parking on the site, subject to the following conditions: 1. The site is now subject to the City's CTR program. 2. Approval of future building permits for AVS will require at least 177 173 parking spaces on the site. 3. This parking variance is based on 400 students enrolled at AVS. If enrollment exceeds 400 students, the City may require the project to demonstrate adequate parking is still maintained or mitigated including the creation of additional parking if the City determines that adequate parking is not provided.

Included with this letter is the complete application for Special Permission - Director Administrative Parking Variance for your review. The future Raisbeck Aviation High School will be a 400 - student public high school operated by the Highline School District. The school is planed to be approximately 75,000sf, 3 -story building and mechanical penthouse. The school will be located on property leased from the Museum of Flight adjacent to their campus. The Municipal Code requires "1 space for each staff member plus 2 spaces for every 5 students or visitors" for high school use. Based on the planed 400 students school capacity and current number of employees of 32 this represents a total 192 spaces. As part of this project we are proposing 150 parking spaces plus an additional 27 temporary spaces for a total of 177 parking spaces. During peak hours, the temporary spaces function as bus and automobile loading and unloading area. This represents less than 8% reduction from the total code required parking spaces. 71 Columbia Street, Suite 500 / Seattle, Washington 98104 t 206 340 9500 f 206 340 9519 / www.bassettiarch.com • Project Name Raisbeck Aviation HS Subject Parking Variance Request Date November 23, 2009 Page 2 of 2 We respectfully request an administrative variance be considered for this project per TMC Ch. 18.56.140 Administrative Variance from Parking Standards.

McBryan, P.E., Principal & Vice Presid REcEntb DEC` 01 2009 BEVE oPmEYT The Highline School District is planning to relocate its existing Aviation Hi_ School program to a new building it proposes to construct in Tukwila, Washington. The existing Aviation High School is currently housed at the former Olympic Middle School site in Des Moines. The site for the new school is located on property owned by the Museum of Flight along the west side of East Marginal Way S at S 92 "d Place. City of Tukwila staff has noted that this project could be an accessory use to the existing Museum of Flight; a museum expansion has been evaluated separately under SEPA as part of a Planned Action.

This technical memorandum provides the traffic and parking analysis to support the SEPA Planned Action and permit applications being prepared for this project. 1. Site and Project Description Aviation High School is an aviation - themed high school that was opened by the Highline School District in 2004. With the proposed project, Aviation High School would be housed within a new 60,000- square -foot (sf) building that would be an accessory use to the existing Museum of Flight. The new building would be constructed on the southwest corner of the S 92nd Place/East Marginal Way S intersection. The school would maintain its maximum enrollment capacity of 400 students. For reference, the school had a total enrollment of 368 students at the end of the 2008 -2009 school year.' Since 2004, enrollment has grown from 103 students to a peak of 387 students in October 2008. The proposed Aviation High School project would provide parking capacity for a total of 177 vehicles including long -term parking for 150 vehicles west of the building, short-term parking for 19 automobiles along the north side of the access drive, and parallel parking for eight vehicles along the south side of the access drive. The spaces along the south side of the access drive would be restricted to school -bus loading/unloading during peak morning and afternoon periods. Vehicular access will occur from an existing driveway on East Marginal Way S at its signalized intersection with S 92 "d Place. The project would also provide a school -bus loading / unloading area along the south side of the access driveways and an automobile loading / unloading area along the north side. The proposed site plan is shown in Figure 1 (attached).

Existing School Traffic Traffic generation for development projects is typically estimated using published rates and equations in Trip Generation.3 However, since Aviation High School already exists and operates in Des Moines (about 10 miles to the south of the proposed site), the best way to determine its traffic generating characteristics is through counts at the existing site. Therefore, to determine the existing school traffic generation, new 24 -hour machine traffic counts were performed at the site's driveways in June 2009. The driveway counts were compiled to determine daily, peak morning, and peak afternoon trip generation. Table 1 summarizes the resulting existing weekday site traffic generation with the June 2009 enrollment level of 368 students. Table 1. Aviation High School — Existing Trip Generation (Enrollment at 368 Students) AM Peak Hour 1 Daily Trips In Out Total School PM Peak Hour 2 In Out Total Aviation High School 1,200 158 87 245 71 127 198 Source: Heffron Transportation, Inc. based on 24 -hour counts at the existing Aviation High School driveways June 4, 2009. 1. The school AM peak hour occurs from 8:00 to 9:00 A.M. 2. The school PM peak hour occurs from 3:00 to 4:00 P.M. Based on these trip generation results, the existing Aviation High School generates higher levels of traffic than would be estimated using published rates for High Schools (Land Use 530) from Trip Generation. The actual AM peak hour rate was 0.67- trips -per- student compared to the published average rate of 0.42 -trips- per - student. The actual school PM peak hour rate was 0.54- trips - per - student compared to the published rate of 0.29- trips - per - student. The daily rate was also higher than the published rate. The higher rates are expected due to the unique program offered at Aviation High School and its relatively small enrollment level. The reported daily trip value is likely higher than on typical average day conditions because the counts reflect an evening event that occurred at the site beginning at about 6:00 P.M. and ending after 8:00 P.M. This event contributed to the higher than expected traffic volumes during the evening hours. When the number of trips that appeared to be related to the event is subtracted, the existing school is estimated to generate a total of 800 trips (400 in, 400 out) on days without an evening event. 2.2. Future School Traffic The proposed new school building will maintain the school's maximum capacity of 400 students. To estimate traffic volumes for the new school at the Museum of Flight in Tukwila, the existing school . volumes were increased to reflect full a capacity enrollment of 400 students. Table 2 summarizes the 3 Institute of Transportation Engineers, 8th Edition, 2008. - 2 - October 30, 2009 Highline School District's Aviation High School Traffic and Parking Analysis • heffron trans•ortation inc. forecast weekday site traffic generation with the full capacity enrollment of 400 students. As shown, the school is expected to generate up to 1,300 trips per day (on days with evening events), 265 AM peak hour trips (170 in, 95 out), and 215 school PM peak hour trips (75 in, 140 out).

The school AM peak hour is expected to continue to occur from 8:00 to 9:00 A.M. 2. The school PM peak hour is expected to continue to occur from 3:00 to 4 :00 P.M. It should be noted that the Highline School District plans to continue providing bus transportation to students living in the District's service area. Students in nearby districts can also use Highline School District transportation with arrangements through the District's Transportation department. Students from other area school districts will need to provide their own transportation. Some students may elect to use King County Metro Transit. 3. Site Access Operations This section evaluates the potential future operations of the site access proposed at the S 92 °d Place/East Marginal Way S intersections. The intersection has two adjacent west legs —each controlled separately by the traffic signal. The northern leg serves as an access driveways for an automobile auctioneer (IAA). The southern leg serves the project site, which is currently vacant. To facilitate this analysis, new morning and afternoon manual turning movement counts were performed at the existing signalized intersection on Wednesday, June 3, 2009. The counts (attached) were performed at times that would coincide with the peak traffic flows at the school -7:30 to 9:30 A.M. and 2:30 to 4:30 P.M. Future conditions with the proposed Aviation High School were evaluated to document the potential impact of the project and to ensure that the site access intersection would operate acceptably. The new school is expected to be complete by January of 2012. To reflect 2012 conditions without the project, through traffic volumes along East Marginal Way S were increased using a 3% annual growth rate. This growth rate was selected based on a comparison of historical counts (2005 and 2007) performed by the Seattle Department of Transportation along East Marginal Way S south of 4th Avenue S —about 2 miles north of the site. Forecast 2012 traffic volumes along East Marginal Way S were combined with the potential project traffic described previously to represent future conditions with the school project. School traffic was assigned to East Marginal Way assuming about half would approach from the north (using SR 509 to the Michigan Street exit and then south to the site) and about half would approach from the south (using I -5 and the Boeing Access Road exit then north to the site). Operations of the site access intersection at East Marginal Way S were evaluated for conditions with the proposed school. The forecast 2012 with - project traffic volumes are shown on Figure 2 (attached). The quality of traffic flow and intersection operations is defined by levels of service (LOS). Levels of service are qualitative descriptions of traffic operating conditions and are designated with letters ranging from "A," which is indicative of good operating conditions with little or no delay, to "F," which is indicative of stop- and -go conditions with frequent and lengthy delay. Traffic operating conditions of the access driveways were analyzed for peak morning and afternoon periods using the - 3 - October 30, 2009 • Highline School District's Aviation High School Traffic and Parking Analysis • heffr on trans •ortation, Inc. Synchro 7.0 traffic operations model. The Synchro 7.0 analysis software is used for analyses within the City of Tukwila for evaluating traffic operations. Based on these analyses, the intersection currently operates at LOS A during both peak periods (morning and afternoon). This very good level of operation occurs because there is very little traffic generated by either driveway that is controlled by the signal. In 2012, with the school operating at its assumed capacity of 400 students, the intersection is expected to operate at LOS B during both the morning and afternoon peak periods. The forecast volumes, intersection operation assumptions, and LOS results are included in the attached LOS calculation sheets. These analysis conditions reflect the peaking characteristics typically found at schools where most of the traffic flow occurs over about 30 minutes —peak flows when students arrive and depart school. To account for this, a peak hour factor (PHF) of 0.50 was applied to all school traffic. It is also recognized that peak hour school traffic could fluctuate based on the availability of school bus transportation, the origins of students in the program, the availability of public transit to serve students, and participation from outside volunteers. Therefore, intersection operations were also tested with a 30% increase in peak hour school volumes. With this increase, the intersection is still forecast to operate at LOS B during both morning and afternoon peak conditions. 4. Transit King County Metro Transit provides bus service near the proposed Aviation High School site. There are bus stops on East Marginal Way S at S 94`h Place just south of the school site adjacent to the Museum of Flight. The stops serve three existing bus routes: Route 154, 173, and 174. Route 154 provides service from Auburn, through Kent, to Boeing Field and ends at the Federal Center South. It operates with four northbound trips in the morning (between about 6:00 and 8:00 A.M.) and four southbound trips in the afternoon (between about 2:50 and 4:45 P.M.). Route 173 provides service from Federal Way, through Kent -Des Moines, to Boeing Field and ends at the Federal Center South. It operates with two northbound trips in the morning (between about 6:00 and 7:30 A.M.) and two southbound trips in the afternoon (between about 3:00 and 4:45 P.M.). Route 124/174 provides all -day service from Federal Way, through Kent -Des Moines, to Boeing Field, the Federal Center South, and into Downtown Seattle. It operates nearly 24 -hours per day with headways (time between consecutive buses) of 15 to 20 minutes during peak periods, and 30 minutes during off -peak periods. Route 124/174 could be used by students of the proposed high school. The northbound trips on Routes 154 and 173 may be too early to serve the students at the proposed high school (since classes will not likely start until 8:30 or 9:00 A.M.), but the afternoon trips could work for some students. 5. Parking The following section outlines the existing and forecast parking demand for Aviation High School and documents the planned parking supply for the project. A review of the City of Tukwila's code requirements follows the analysis of the school's demand and supply. Finally, analysis of the Museum of Flight parking needs is provided. - 4 - October 30, 2009 Highline School District's Aviation High School Traffic and Parking Analysis 5.1. School Demand and Supply • heffron trans•ortation inc. A parking demand rate for Aviation High School was developed using counts performed at the existing school in Des Moines. A field parking demand count was performed at 10:15 A.M. on June 4, 2009. The parking demand at that time was 92 cars and 1 motorcycle (93 vehicles total). The 24 -hour driveway counts were used to calculate hourly parking accumulation on the site throughout the day. The calculated parking demand from the existing accumulation analysis matched the observed parking demand for the hour between 10:00 and 11:00 A.M. Based on the accumulation results, the existing peak parking demand of 99 vehicles occurred between 11:00 A.M. and 12:00 P.M. Using the existing enrollment of 368 students, the school had a peak parking demand rate of 0.27- vehicles - per - student. This is slightly higher than the average peak parking demand rate of 0.26- vehicles - per - student published in Parking Generation's for High Schools (Land Use 530). These values are reasonable given the school's staffing level and number of student parking passes issued. At the end of the 2008/2009 school year, the school had issued a total of 72 parking passes to students and there is a total of 32 staff (including custodial and kitchen staff) working at the school. These values reinforce the peak parking demand after considering typical absenteeism and variations in daily schedule. The parking demand rate developed for Aviation High School was applied to the future enrollment capacity of 400 students. As a result, the school is expected to have a peak demand of 108 vehicles. The future demand and parking accumulation profile are presented in Table 3 below. As shown, the future peak parking demand is expected to occur between 11:00 A.M. and 12:00 P.M. Table 3.

The proposed Aviation High School site plan includes a total of 177 parking spaces. Long -term parking for 150 vehicles would be provided in a lot located west of the school building. Short-term parking for 19 automobiles is proposed along the north side of the access drive. This would include a small cell -phone waiting lot with seven (7) parking spaces and parallel parking for 12 vehicles that would be signed for short-term load/unload only during peak arrival and departure times at the school. The project also proposes parallel parking for eight (8) vehicles along the south side of the access drive. These spaces would be restricted to school -bus loading /unloading during peak morning and afternoon periods. The proposed parking supply is expected to be more than adequate to accommodate the expected peak parking demand and would be approximately 61% utilized during the peak period between 11:00 A.M. and 12:00 P.M. Even if all parking demand occurred only in the long -term parking spaces, that lot would only be 72% utilized during the peak period. The excess parking supply would be provided to accommodate seasonal or annual variations and would be used occasionally for evening events that would occur at the school. 5.2. City of Tukwila Code Requirement The City of Tukwila outlines its Off - Street Parking and Loading Regulations in Tukwila Municipal Code (TMC) Section 18.56. The minimum number of off - street parking spaces for specific land uses is outlined in Figure 18 -7. For high schools, City code requires one space for each staff member, plus two spaces for every five students or visitors. Based on the planned 400 - student school capacity and the expected number of employees (32), the City would require a minimum of 192 spaces. However, this is far more than would be required based on the parking study results presented in the previous section. The City has established a process by which an administrative variance to the parking requirement can be granted. TMC Section 18.56.140 outlines the process' for a variance and lists the criteria for approval. The code states that: "A reduction may be allowed, pursuant to either an Administrative variance or requests to the Planning Commissions, after: a. All shared parking strategies are explored. b. On -site park and ride opportunities are fully explored. c. The site is in compliance with the City's commute trip reduction ordinance or, if not an affected employer as defined by the City's ordinance, agrees to become affected. d. The site is at least 300 feet away from a single-family residential zone. e. A report is submitted providing a basis for less parking and mitigation necessary to offset any negative effects." The code also states that, in addition to the above requirements, "...the Director may require specific measures not listed to ensure that all impacts with reduced parking are mitigated. Any spillover parking which cannot be mitigated to the satisfaction of the Director will serve as the basis for denial." As described previously and as shown in Table 3, the proposed Aviation High School is expected to generate typical school -day peak parking demand of 108 vehicles. The proposed supply of 177 parking spaces is anticipated to be adequate for typical school -day conditions and would provide excess parking supply for seasonal or annual variations and occasional evening or weekend events. 5 City staff has indicated that Code was recently revised to state that variances over 10% would be addressed in a hearing before a Hearing Examiner rather than before the Planning Commission. - 6 - October 30, 1009 Highline School District's Aviation High School Traffic and Parking Analysis • heffron t rans • ortation, Inc. A variance from the City's parking code requirement should be granted for the following reasons: 1) The District proposes to construct 177 on -site parking spaces. This parking supply would exceed the forecast typical school -day peak demand by nearly 64 %. Of the 177 spaces proposed, 19 along the north side of the access driveway would be designated as short-term parking and/or loading/unloading spaces during peak arrival and departure times. The eight parallel parking spaces on the south side of the access driveway would be restricted to school - bus loading/unloading during peak periods. However, all of the spaces could be used for parking during off -peak times. The total on -site supply of 177 spaces would be available for midday, evening, or weekend use. 2) The minimum parking required by Tukwila code is nearly 76% higher than the peak demand forecast for Aviation High School and nearly 85% higher than the peak demand that would be forecast using rates published by the Institute of Transportation Engineers in Parking Generation6 for a high school. 3) Since the school would not generate demand beyond the supply that is proposed, no shared parking strategies would be required for school demand. 4) The Highline School District plans to provide school bus transportation for students living in the District service area. Students in nearby districts can also use Highline public school transportation with arrangements through the school district transportation department. 5) The school would be located adjacent to East Marginal Way S and within 900 feet of an existing Metro bus stop. The bus stop serves three routes including one that operates nearly 24 -hours per day with headways of 15 to 20 minutes during peak periods, and 30 minutes during off -peak periods. 6) The school would not be an affected employer under the City's Commute Trip Reduction (CTR) ordinance, since it would not employ 100 or more full -time employees. Since the proposed parking supply is anticipated to meet the peak demand, the school's participation in a CTR program would not be effective. 7) The site is more than 300 feet from any single family zone. 8) Since the school would be located on a site owned by the Museum of Flight and is expected to be an accessory use to the museum, the school would have a shared parking agreement with the museum. This agreement would allow museum use of the school parking lot during occasional peak events when school demand does not occur. 5.3. Museum of Flight Parking The proposed Aviation High School would be an accessory use to the existing Museum of Flight. Since the project proposes fewer than the City's code required minimum number of parking spaces for a high school, the City of Tukwila has requested an analysis of the Museum of Flight's parking conditions to ensure that the Aviation High School project would not result in adverse impacts to parking. Museum of Flight parking conditions were analyzed based on data provided by the Museum 6 Land Use 530, 3rd Edition, 2004. - 7 - October 30, 2009 • Highline School District's Aviation High School Traffic and Parking Analysis • heffron trans•ortation Inc. and based on data in the Traffic Impact Assessment – Museum of Flight Expansion report. This report included the results of detailed traffic and parking studies performed at the museum in April 2001. The Museum of Flights staff provided information about average daily visitors during school months (September thru May) and summer months (June thru August). Museum staff also provided information about weekend visitor levels and peak events. These values were compiled with the historical data from the 2001 report to estimate typical museum parking demand on weekdays during the school year. Weekday attendance at the museum during the school year averages about 500 visitors per day. Peak hours for the museum are from 10:00 A.M. until 1:00 P.M. The highest hourly volume —about 15 %—of daily visitors enters at between 10:00 and 11:00 A.M. The 2001 report found peak weekday parking demand at the museum to be just over 270 vehicles just after 11:00 A.M. on a busy Thursday. Saturday demand was just under 300 vehicles at about 2:00 P.M. The museum has about 375 on -site parking spaces. During summer months, weekday demand increases since the average daily attendance is closer to 800 visitors per day. Attendance on weekend days ranges from about 1,000 per day during the school year, and 1,500 to 2,000 during weekend days in summer months. The museum also hosts occasional evening events that can draw relatively large groups. For weekends and evenings, the museum has overflow parking available (about 260 spaces) to the south of its main lot in the Boeing parking lot. When combined with the main museum parking lot, the museum has about 635 spaces available near the building and on the east side of East Marginal Way S for peak weekend and evening events. The Museum has also used its property on the west side of East Marginal Way S (including the site proposed for the Aviation High School) for overflow parking for peak events. The only times this area has been used for overflow parking demand generated by the Museum is for the week when the Blue Angles are in Seattle for SeaFair- typically the last week in July or the first week in August. It is anticipated that Highline School District would maintain a shared parking agreement that would allow Museum of Flight overflow parking to occur on the Aviation High School parking lots during times when they are not needed for school activities. This would include summer months and weekends, especially during SeaFair week. Based on the above analysis and on previous findings from data collection in 2001, the proposed Aviation High School project is not expected to adversely impact parking generated by the Museum of Flight and would not result in any new parking impacts. 6. Findings and Recommendations The proposed Aviation High School, at its maximum capacity of 400 students, is expected to generate up to 1,300 trips per day (on days with evening events), 265 AM peak hour trips (170 in, 95 out), and 215 school PM peak hour trips (75 in, 140 out). It is oxpected to generate a peak parking demand of 108 vehicles between 11:00 A.M. and 12:00 P.M. on typical school days. The proposed parking supply of 177 on -site spaces (150 long-term and 27 short-term and/or loading/unloading spaces) is expected to accommodate the school's peak parking demand. Access would be provided to the school from an existing signalized driveway on East Marginal Way S at S 92 °d Place. Since the existing intersection has two west legs that are controlled separately by the signal, the school access driveway, its intersection with East Marginal Way S, and the traffic signal would require modification to accommodate the school project. The following should be considered as part of the design for the access intersection: 7 David I.

Extensive signage, roadway markings, and channelization would be included to clearly identify the school entrance and the proper vehicle paths to access the site. Advance signage for the school should be provided on East Marginal Way S. • Signage, roadway markings, and channelization should be provided to clearly identify the IAA property entrance and the proper vehicle paths to access that site. • Right turns on red should be prohibited for southbound turns from East Marginal Way S to the school and from the IAA property to southbound East Marginal Way S. • Revise the traffic signal to provide pedestrian actuated pedestrian signals, crosswalks, and ADA compliant curb ramps for crossing the driveways. We understand City staff has recommended that no crosswalk be provided across East Marginal Way and that signage should be installed directing pedestrians to use the Museum of Flight sky bridge. • The traffic signal should be modified to serve school traffic during morning and afternoon peak periods. This could include changes to signal operations to provide a protected -only left - turn phase from northbound East Marginal Way S to the site. It will require revisions to the timing to provide adequate green time for the school approach. It may also include installation of actuation devices (loop detectors or video detection) for affected movements. • The access design should include a path that will allow vehicles turning into the IAA property driveway to have an exit path for drivers without access to the security gate. • Maintain a shared parking agreement that would allow Museum of Flight overflow parking to occur on the Aviation High School parking lots during times when they are not needed for school activities. This would include summer months and weekends, especially during SeaFair week. Attachments: Figure 1. Proposed Site Plan Figure 2.
