LEVEL OF SERVICE DESCRIPTIONS SIGNALIZED INTERSECTIONS Level of Service Delay seconds/vehicle Description A < 10.0 Little or no delay B > 10.0 - 20 Short traffic delays C > 20 - 35 Average traffic delays D > 35 - 50 Long traffic delays E > 50 - 80 Very long traffic delays F > 80 Severe congestion LEVEL OF SERVICE STANDARD The City's Level of Service standard for intersection operation is Level of Service "D". Caltrans Level of Service standard is the threshold between LOS "C" and "D". A project impact would be considered to be significant if it causes an intersection that is operating at an acceptable Level of Service to worsen to an unacceptable Level of Service. EXISTING PEAK HOUR TRAFFIC CONDITIONS Existing morning and evening peak hour turning movement counts were made at the study intersections during the morning (7:00 to 9:00 AM) and evening (4:00 to 6:00 PM) peak periods. Existing lane configurations at the study intersections are shown on Figure 3. Existing peak hour traffic volumes are shown on Figure 4. Copies of the count data forms are provided in the Appendix A to this report. Existing peak hour operations were evaluated and the results are summarized on Table 1. All study intersections are currently operating at an acceptable Level of Service in both peak hours. Copies of the ICU and HCS sheets for the Existing Conditions analysis are provided in Appendix B of this report. PROJECT OPENING YEAR CONDITIONS A short-term future analysis will evaluate traffic conditions in the Opening Year of the project. Short-term future traffic consists of existing peak hour traffic with an annual growth rate of 1% per year, based on direction from City staff, applied for each year between existing conditions and the Opening Year for the project. In addition, traffic from any approved prof ects in the vicinity of the proj ect is added to the peak hour volumes. The Crazy Horse Square project is anticipated to be completed in 2007. A traffic growth rate of 1.0% per year was applied to existing traffic to account for ambient growth in the area. No other approved projects in the vicinity of the project site were identified by City staff. Opening Year peak hour traffic volumes at the study intersections are shown on Figure 5. Peak hour operating conditions for the Project Opening Year without the project are summarized on Table 2. All study intersections are forecasted to continue to operate at an acceptable Level of Service in the Project Opening Year.
