4.Written Comments on the Draft EIR and Responses to Comments Although all traffic impacts identified in the Draft EIR would be mitigated to a less-than-significant level with mitigation measures,the approval process for a portion of one measure that would address a queueing impact at the Stoneridge Drive/Johnson Drive intersection(Mitigation Measure 4.D-1d) would require Caltrans approval and that of other non-City agencies, and thus is not fully under the control of the City of Pleasanton. Accordingly, because CEQA requires that mitigation measures be"fully enforceable through permit conditions, agreements, or other measures"(CEQA Sec. 21081.6(6)), this impact would necessarily be considered significant and unavoidable,as further described below. Regardless of the involvement of other agencies, the City is required to ensure completion of traffic mitigation measures prior to operation of uses in the area of the EDZ that would result in the impacts. Chief impacts identified in the Draft SEIR and addressed in the comments are further discussed below. Impacts at the Intersection of Stoneridge Drive and Johnson Drive Several comments requested clarification regarding impacts to traffic at the intersection of Stoneridge Drive and Johnson Drive. As shown in Table 4.D-2, page 4.D-6 of the Draft SEIR,this intersection currently operates at LOS C or better, indicative of acceptable traffic operations with average delays. The Draft SEIR also concludes that the addition of traffic generated by the EDZ would worsen conditions at this intersection to an unacceptable LOS E, a significant impact. This impact would not occur under conditions caused by Phase I of the EDZ(which includes a club retail use,hotel,and limited amount of retail), but rather would occur with full buildout of the EDZ. Implementation of Mitigation Measure 4.D-1c would reduce the impact to a less-than-significant level,and would include the following: • The construction of a third left-turn lane from Stoneridge Drive to Johnson Drive and one additional lane on Johnson Drive that would receive northbound traffic; • The construction of an additional southbound right turn lane on Johnson Drive for traffic turning onto Stoneridge Drive, and • The rebuilding(widening)of a part of Johnson Drive that extends north from the intersection of Stoneridge Drive about 700 feet, from two and four lanes to six lanes(three northbound lanes and three southbound lanes). While increased traffic from Phase I development of the EDZ would not result in level of service impacts at the intersection of Stoneridge Drive and Johnson Drive, it would result in two impacts related to vehicle spillback.The first impact would result from vehicle queue spillback from the 1-680 northbound off-ramp exiting onto Stoneridge Drive and southbound off-ramp exiting onto Stoneridge Drive: spillback from these off-ramps onto the freeway mainline would result in a hazardous condition due to the potential speed differential between moving vehicles on the freeway and queued vehicles on the off-ramp. Second, queues at the eastbound left-turn lane from Stoneridge Drive to Johnson Drive would exceed the existing storage,resulting in vehicle queue spillback from Stoneridge Drive onto adjacent intersections and the freeway mainline. With this impact, through traffic on Stoneridge Drive would be periodically impeded, and southbound vehicle queues on Johnson Drive could block access to driveways along the road.
