Larson Property Traffic Impact Study Page b. Trip Distribution The distribution of new trips to and from the Larson property developed as a hotel/motel will be heavily weighted toward Interstate 5 during the AM and PM peak hours. A secondary origin/destination would be Franklin Blvd. (Ore. 99 & Bus. 126). In order to analyze a worst-case condition for the Glenwood Blvd. intersections, all traffic was assigned to use the Glenwood Blvd./Glenwood DrivefMoon Mountain intersection and no trips were assigned to Laurel Hill Drive. The trip assignments fOr the Larson property to the intersections in the study area for the proposed zone change development are shown in Figure 5 in Appendix A. 3. Development Impacts - 2004 The total estimated traffic at study area intersections in 2004 with the proposed zone change will be the sum of the existing traffic volumes (Figure 3) and the hotel/motel trips (Figure 5). Total peak hour traffic at thc study area intersections is shown in Figure 6 in Appendix A. The results of the LOS analyses for the study area intersections with the proposed zone change compared to the existing 2003 conditions, are shown in Table 4. The analyses show that all intersections operate at acceptable service levels.
