Comprehensive Plan Policy A related policy from the Comprehensive Plan: 1.8.8 Encourage facilities and improvements that support transit use in new development, redevelopment, and street projects. The Tukwila City Council made the following findings during their deliberations on the Tukwila Village Development proposal. Within the Development Agreement is the following: 1. "Goal 8.2.22 of the City s Comprehensive Plan provides for the establishment of an overlay district in the designated urban renewal area generally between South 140th Street, 42nd Avenue South, South 146th Street, and 37th Avenue South that may allow increased building heights, reduced residential parking requirements, and other alternative development standards subject to specific criteria, in order to encourage well designed compact transit oriented and pedestrian friendly redevelopment to activate the community along Tukwila International Boulevard." 2. "The adoption of supplemental development standards and criteria providing for taller building heights and reduced parking requirements was intended to make urban densities and amenities more likely while the impact upon residential areas resulting therefrom would be lessened by requiring development along Tukwila International Boulevard, more significant structured parking and pedestrian friendly amenities;" Engineering Analysis Within the Traffic Impact Analysis prepared by Parametrix (May 2013,) (Attachment D) is a description (pages 14 -16) on peak parking demand. The author cites the Institute of Traffic Engineers (ITC) Parking Generation Manual. The analysis does not consider the phasing of the uses but instead considers the uses in total. The peak parking demand analysis (Table 9) is not absolutely relevant because the parking supply is not completely shared. All the parking for the residential units is within the garage spaces, which are not accessible to the commercial use customers; however, excess stalls are available for employees in some of the secured garage areas. This employee parking, when not in use by the employees during the evening and on weekends, will be available for "overflow" parking demand. Among the other uses — retail space, library, office and community policing — the estimated peak parking period would be noon during a weekday. The authors did not consider weekend parking demand. The higher amount of office space relative to the commercial space, which has a peak parking demand during the week mid- morning, relative to the commercial, which has a peak during mid- day, provides a greater opportunity for sharing to occur because of the difference in the peak demand periods. Of note, the Parametrix report states that although they did not analyze internal capture rates between the uses that they typically estimate a 10% internal capture rate. That means that 10% of the parkers on site typically will use more than one use without using their car for another trip. Staff Report L13 -031 Page 8 of 12 104
