8. Traffic Impacts 8.1 Existing Traffic Conditions and Levels of Service Ten key intersections in the downtown area were selected for analysis based on recent impact analyses of the proposed Everett Special event Center immediately adjacent to the County campus site. These intersections included key regional access routes such as Pacific Avenue and Hewitt Avenue from the I-5 interchange (Maple Street) to Rucker Avenue and local intersections that would subject to new or diverted traffic. Recent traffic counts were obtained for the ten key intersections in the PM Peak Hour period. All counts were adjusted to a current (2001) base year. The local traffic volumes are shown on Figure 4 while turning movements at all ten intersections are contained in Appendix A. Additional traffic counts were obtained on access driveways to the existing County parking garage and two immediately adjacent intersections on Pacific Avenue for the AM Peak Hour. The local traffic volumes are shown on Figure 5 for the AM Peak hour. Level of service calculations were conducted for all ten street intersections and the garage entrance using the HCS method of analysis as shown on Table 9.
