sc L SILVER LAKE CENTER Transportation Planning • In regional terms, Silver Lake Center is at the confluence of Interstate 5 with SR527. Just to the west of this intersection is the Old Pacific Highway(Highway 99). Whereas Interstate 5 is the"spinal column"of coastal North America, it combines with Hwy.99 and SR527 to form the principal transportation network in the North Sound; • The secondary transportation framework consists of three tributaries that link Silver Lake Center with communities to the east and west of Interstate 5. South of the Site is SR 96(128th Street)which is a primary feeder to Interstate 5 and an arterial that now connects to Highway 9 in the east. Emanating on the western boundary of the Site is 112th Street which extends westerly to Interstate 5,then on to Highway 99 and the Paine Field Industrial Park. The current reconstruction of 112th Street will be completed by the end of 2003,becoming the primary HOV connector to a Park&Ride in the median of Interstate 5. This arterial is also planned to extend around the south end of Paine Field,connecting to the upscale coastal communities of Harbor Point and Mukilteo. Along the north boundary of the Site is 110th Street which is a local connector to the large residential subdivisions east of Silver Lake, ultimately intersecting with Seattle Hill Road and the Snohomish River Valley; • Other collector roads that constitute a tertiary transportation network are 35th Avenue,which is currently closed for extensive widening through the east side of Mill Creek up to 116th Street,then beyond to 100th Street; • Whereas 112th Street does not presently connect to Interstate 5,studies have been underway for many years to implement this important connection. This will be accomplished initially by way of High Occupancy Vehicle(HOV)ramps under the Rapid Transit Authority(RTA)funding which will also fund construction of the Park&Ride accommodating some 1200 cars. Studies are also in progress for all purpose traffic ramps connecting 112th Street to Interstate 5; • The Average Daily Traffic Volume(ADTV)projected for the completed SR527 is 36,000 cars; • The ADTV for SR526(SR527 as it turns to the west and crosses I-5)is 80,000 cars. SR526 has a "freeway"configuration between I-5 and the Boeing Everett Campus; • The ADTV for 112th Street is 30,000 cars and the ADTV for Interstate 5 is 250,000 cars; • Whereas the transportation arterials provide the urban framework for Silver Lake Center, it is the geometry of this framework that provides a very unique and extremely valuable asset to the Site. This geometry is created by: 1. the curvilinear nature of SR527 as it navigates the shores of Silver Lake providing long vistas of visual access across the Lake to the Site for northbound traffic. 2. the offset of the 110th and 112th Street T-Intersections with SR 527 such that the high volumes of eastbound traffic on 112th seeking an easterly connection to 110th or a southerly or northerly connection to SR527,flow directly into the project lands,and 3. conversely,traffic westbound on 110th seeking connection to SR527 or a westerly connection 112th must navigate the north and west boundaries of Silver Lake Center; Silver Lake Center Project Profile Page 4 of 21
