Administrative Draft Environmental Impact Report <br /> Gill Medical Center Project <br /> Traffic volumes under Existing Plus Phase 1 conditions would be generally higher than under Existing <br /> Conditions and, as a result, vehicle delay at study intersections under Existing Plus Phase 1 conditions <br /> would be higher than under Existing Conditions. Under Existing Plus Phase 1 conditions, LOS at 14 of the <br /> 16 study intersections would be at acceptable LOS D or better during both the a.m. peak hour and the <br /> p.m. peak hour. Thus, no improvements are needed at these 14 intersections to achieve acceptable LOS. <br /> Impacts to the two study intersections that would operate at unacceptable LOS under Existing Plus Phase <br /> 1 conditions are discussed further below. <br /> 12. Eight Mile Road&SR 99 West Frontage Road. <br /> Under Existing Plus Phase 1 conditions, the intersection of Eight Mile Road &SR 99 West Frontage Road <br /> would operate at LOS F with 68.3 seconds of delay during the a.m. peak hour, and at LOS F with 98.0 <br /> seconds of delay during the p.m. peak hour. LOS F is considered unacceptable. <br /> 13. Eight Mile Road&SR 99 East Frontage Road <br /> Under Existing Plus Phase 1 conditions, the intersection of Eight Mile Road & SR 99 East Frontage Road <br /> would operate at LOS D with 23.8 seconds of delay during the a.m. peak hour, and at LOS F with 67.4 <br /> seconds of delay during the p.m. peak hour. LOS F is considered unacceptable. <br /> Compared to Existing Conditions, the project-related increase in delay at these two intersections would <br /> not be greater than five seconds during either the a.m. peak hour or the p.m. peak hour. Therefore, based <br /> on information presented in the General Plan Policy Consistency Criteria section above, the Phase 1 <br /> project-related inconsistency with intersection LOS General Plan policies is considered less than <br /> significant. No mitigation is required. <br /> It should be noted that while no project-related improvements are required at these intersections under <br /> Existing Plus Phase 1 conditions, as shown in Table 4.19-5, implementation of recommended <br /> improvements for Existing Conditions at these two intersections would result in the following: <br /> At the Eight Mile Road & SR 99 West Frontage Road intersection operations would be LOS B with <br /> 14.4 seconds of delay during the a.m. peak hour and LOS C with 27.8 seconds of delay during the <br /> p.m. peak hour. LOS B and C are considered acceptable. <br /> At the Eight Mile Road & SR 99 East Frontage Road intersection operations would be LOS D with <br /> 23.8 seconds of delay during the a.m. peak hour, and at LOS F with 67.4 seconds of delay during <br /> the p.m. peak hour. LOS F is considered unacceptable. <br /> Table 4.19-5.Intersection Level of Service-Existing Plus Phase 1 Conditions With Recommended Improvements <br /> Study Intersections Inters.
