Figure 7 illustrates the project trip assignment based on <br />the project trip generation and the trip distribution identified above during the weekday a.m. and <br />p.m. peak hours. Figure 8 illustrates the additional trips possible during Sunday morning Church <br />services. <br />EXISTING PLUS PROJECT CONDITIONS <br />Traffic generated by the project was added to the existing traffic volumes at the study area <br />intersections. Figure 9 shows the resulting existing plus project a.m. and p.m. peak-hour traffic <br />volumes. Figure 10 shows Sunday morning traffic volumes with the proposed Church. Both figures <br />also include the anticipated traffic volume from the proposed residential project. <br />Existing Plus Project Intersection Level of Service Analysis <br />Table D summarizes the results of the existing plus project a.m. and p.m. peak-hour LOS analysis for <br />all study area intersections. As Table D indicates, all study area intersections are anticipated to <br />operate at an acceptable LOS (i.e., LOS D or better) in both the existing a.m. and p.m. peak hours <br />with implementation of the project. <br />Table D: Existing Plus Project Intersection Level of Service Summary <br />Intersection AM Peak Hour PM Peak Hour Sunday Morning <br />ICU/Delay LOS ICU/Delay LOS ICU/Delay LOS <br />Existing <br />1.

Therefore, as seen in Tables A and D, there is no delay at Jaguar <br />Way/Proposed Residential Driveway in the existing condition. With the addition of residential and <br />Church traffic during the weekdays and on Sundays, the residential driveway on Jaguar Way is not <br />expected to experience significant delay, according to the City’s guidelines. <br />3-66
