7A Page 21 Mitigation 9-2. The addition of a second eastbound left-turn lane on Woodside Road (SR 84}would achieve LOS D conditions under Maximum Intensity conditions. This improvement, however, would require intersection widening to provide adequate length fior the additional left-turn lane. The improvement would also require Caltrans approval, which is uncertain at this time. Therefore, because implementation of this improvement is not assured, this intersection impact would be a significant unavoidable impacf. Findings: The changes or alterations proposed by mitigation measure 9- 2are within the responsibifify and jurisdiction of Caltrans and not the City of Redwood City. Caltrans can and should adopt proposed mitigation measure 9-2. 6mpact 9-3: impact on Middlefield RoadlJefferson Avenue Intersection--Maximum Intensity Precise Plan Alternative. During the PM peak hour, the Maximum Intensity project traffic increment would reduce the level of service to LOS E and increase average delay by more than five (5) seconds at the intersection of Middlefield Road/Jefferson Avenue. This change would represent a significant impact. Mitigation 9-3(a). Restripe the southbound approach of Middlefield Road to one through lane and one right-turn lane, and prohibit southbound left turns. These changes would result in an acceptable LOS D under the Maximum Intensity altemative, thereby reducing the project impact to a Less-than- significant level. or Mitigation 9-3(b). Implement Mitigation 9-3(a} plus restripe northbound Middlefield Road to two (2) left-turn lanes and one shared through/right-turn lane. Tl~iese changes would result in an acceptable LOS D under the iviaximuirt Intensity buildout altemative, thereby reducing the project impact to a less-than- significantlevel. or Mitigation 9-3{c). Restripe the southbound Middlefield Road approach to a shared left-through lane and one right-turn lane; restripe northbound Middlefield Road to one left-turn lane, one shared left-through lane, and one right-turn lane; and implement a split phase signal operation for northbound and southbound Middlefiield Road. These changes would result in an acceptable LOS D under the Maximum Intensity alternative, thereby reducing the project impact to a less-than-significant level. or Atty/Reso/Reso.1683 4 030707
