4.2 TRAFFIC AND CIRCULATION The specific turning movements that result have been incorporated into the project intersection analysis. Figures 4.2-3 and 4.2-4 illustrate the peak-hour existing-plus-project trip volumes. Project Impacts on Street Network The number of vehicle trips generated by the proposed project were added to existing volumes at the six intersections and the level-of-service operations for the existing plus project conditions were determined as shown in Table 4.2-3. With the addition of project traffic, the LOS would be unchanged at all six of the studied intersections during the AM peak hour and PM peak hour. In general, the number of trips generated by the project overall are very low, as evidenced by the existing plus project operating conditions. Therefore, the vehicle trips generated by the proposed project would not significantly impact the traffic circulation or intersection operating conditions. Six of the homesites would only access Forest Lake Road. The number of vehicle trips generated by these homes would not alter the existing operating conditions at the Lower Sacramento/Forest Lake intersection. The majority of the project's trips would utilize the Peltier/Davis intersection,but the total number of peak-hour trips (approximately 20) would be low and would be concentrated on the portion of Davis Road north of Peltier Road which has very low existing volumes. At the intersection of Peltier/Ray the project trips would primarily be through trips to the freeway and would have almost no effect on the operating conditions. At the four-way stopped intersections of Lower Sacramento/Peltier and Davis/Turner, overall delays would increase a tenth of a second or less, which would not affect the existing operating conditions. The level of service would also remain unchanged at the intersection of Davis/State Route 12. Although the intersection operates at LOS E for the minor street turning movements,this is an existing condition. The proposed project would add five or six vehicle trips to this intersection which would comprise less than one percent of intersection's total volume and, therefore, would not be a significant impact. Project Traffic Signal Warrant Assessment On the basis of the projected existing-plus-project volumes, the intersections were re-examined to determine if signal warrants would be met. The project trips would not significantly alter any of the intersection volumes to warrant signalization, and volumes at all of the intersections except for Davis/State Route 12 would remain well below the minimum threshold levels. As discussed on page 4.2- 7 of this report, the Davis/State Route 12 intersection currently experiences volumes at the minimum threshold levels for which a traffic signal may be justified. The project traffic would add five to six peak hour trips to the intersection, which represents an increase in the total intersection volumes of approximately one-half of one percent, which is not a measurable impact. 4.2-10
