Resolution 3528 - Laserfiche WebLink

• 100th Street did not exceed capacity based on the City's EIS analysis of Boeing traffic and therefore is not included as a mitigation improvement. However, the 100th Street/Airport Road intersection and approach lanes on 100th are scheduled for improvement and Boeing's share has been identified for the County for this intersection and approach lanes (see Decision Document pg 42, Item 2 - County Intersections). • 132nd Street is included in the mitigation from SR-527 to 35th Street. The segment from 35th to SR-9 is largely a new alignment and, based on Boeing peak travel (2:30 to 3:30 p.m.), would contribute only a small percent to traffic (less than 5 percent of travel on the route). Congestion on the new alignment (by definition) would not exceed capacity and, therefore, would not be included as mitigation. • Airport Road widening is listed on page 39, Item 1, as 128th Street/Airport Road since it is signed as 128th at the project's eastern terminus (8th Avenue West). The responsible jurisdiction and project limits are indicated. • In general, impacts beyond about five miles of the site, particularly on local routes is small relative to other traffic on these routes. Since the Boeing peak (2:30 to 3:30 p.m.) was used as the "worst case" condition under SEPA, the Boeing peak was the basis for most capacity calculations. ITMO requires that the facility exceed capacity in order to be slated for mitigation. County routes some distance from the site do not exceed capacity during the Boeing peak and the number of first shift workers on the system in these areas during the normal peak (4:30 to 5:30 p.m.) is very small. Conclusions: • The record indicates that: two of the projects (112th and Airport Road) alleged to be omitted from the mitigation are listed in the Decision Document as required Transporta- tion Mitigation Improvements. • One of the projects (132nd Street) is limited in scope to the segment from SR-527 to 35th and does not include the extension to SR-9 which would not be supported by the EIS impact analysis or the City's method of assigning mitigation responsibility. • Mitigation can be required only to the extent attributable to impacts generated by the Boeing Expansion. • One project (100th Street) is not included in the mitigation, but it's intersection with Airport Road and the approach lanes to Airport Road are included as one of the County intersection improvements. • The record does not include data or studies that support appellants' allegation. 35
