Ms. Lindsay Brown �iiiiiiiiiiiiiiiiii �� February 28, 2017 REVISED MAY 1, 2017g IV�� Page 3 of 8�� ' �iiilllll h 3. Sports Fields Netting and Fencing Height Variance — The new ball fields require a 10 -foot high chain link fence with 20 -foot high netting above the fence (total height of 30 feet). The tennis courts will also have 10 -foot high chain link perimeter fence.. The fencing will be located outside the required perimeter yard setback areas. These are customarily required to contain errant balls within the ball fields or courts. Pursuant to the code citation above, the ball fields and central two tennis courts are exempt from the height restrictions, as they are located in the PRO district. Birth -to- Kindergarten Center Height Variances The new Birth -to- Kindergarten (B2K) Center is also located in the LDR Zone with a PRO overlay. The height requested is 35 feet, which is a 5 -foot height variance. The LDR zoning district has a maximum building height of 30 feet, while the PRO overlay allows a maximum height depending on the location of the structure, up to a maximum of 50 feet. The use will not be for public recreation purposes, but rather for public education purposes; therefore, the variance is requested. The PRO allows 1 foot of additional height for every 4 feet of excess building setback. The table below shows the allowed building height for the B2K building based on its setback from the property lines. The table shows that the proposed height of 35 feet is within the allowable building height based on setbacks. ..__ ......................... ._........_.-a w _ ... _,_._. ................. .................... .� .................... .............................., w�w Birth -to- Kindergarten Center Maximum Buildinc_Height in Relationship to Setbacks Foster High School currently has 251 parking spaces. Figure 18 -7 in Tukwila's code lists the minimum parking as one for each staff member plus two for every five students or visitors. This is broken down as follows: There are 83 employees on campus = 83 spaces There are 878 students = (878/5) *2 = 351 spaces Total parking required by code = 434 spaces The property proposes to provide :1 7 1174 spaces to accommodate the daily use and better align with actual usage. The requested reduction in parking is greater than 10 percent of either the existing parking or the zoning required parking, and therefore requires Type III review.. Please see the submitted Parking Analysis and the narrative describing consistency with the variance criteria for the reduction in parking in Section B of this letter, below.
