1. Includes 122 parking spaces at Showalter, 73 spaces at 132K, and 12 spaces in the Foster High bus loop, available only for <br />special events. Not included in supply count are 17 spaces marked for Tukwila pool patrons. <br />2. As observed by Gibson Traffic Consultants. Includes parking needs of technology and maintenance building employees who will <br />work and park in an offsite location after project approval. <br />3. Nighttime demand calculated for max attendance at the Performing Arts Center. 2017 is the last year graduation ceremonies will <br />be held onsite. <br />Other factors that can affect parking utilization at Foster High during evening hours include the <br />scheduling of multiple events in the same evening, and the relative convenience of parking on <br />the street and walking a shorter distance to the campus than the distance from Showalter <br />Middle School and B2K parking lots. City staff has heard complaints from residents near the <br />High School about attendees at evening events at the High School parking on residential <br />streets, preventing residents from parking near their houses. This neighborhood impact has <br />recently worsened as property owners near the schools subdivide their lots, generating <br />increased demand for on- street parking while creating few additional on- street spaces. <br />If no increase in student enrollment is anticipated as a result of Foster High School expansion <br />then the parking demand is not likely to increase with project approval. However offsite parking <br />impacts could result from special events; and scheduling of multiple events during the same <br />time. <br />The negative impacts generated by parking demand surpassing parking supply can be mitigated <br />through conditions of approval that directly address those impacts and with improved <br />management of parking resources. As a condition of approval of their 1989 Conditional Use <br />Permit, the District was required to direct drivers to overflow sites when parking demand <br />exceeds supply during evening events. An effective parking management plan could include <br />flaggers directing drivers on where to park, and a map showing the designated walking route <br />from Showalter parking areas to the Foster campus. Through the City's temporary and special <br />event permitting process, larger events could propose their own measures to mitigate traffic and <br />parking impact which may include shuttle service and advertisement of designated parking <br />locations. <br />Ga <br />32 <br />
