Table 1 (continued) SUMMARY OF POTENTIALLY SIGNIFICANT TRANSPORTATION AND TRAFFIC IMPACTS Impact Location Affected Mitigation Physical Improvement or Other Mitigation Level of Impact Measure After Mitigation Johnson Drive and Park and Ride Lot Intersection.The M-TR-1 Implement TDM Program Significant and addition of vehicle trips generated by Phase I of the EDZ and Unavoidable other near-term projects during the PM peak hour would worsen Funding:City's TIF, the side street movement at this intersection to LOS E; under except M-TR-1— full buildout conditions,this condition would worsen to LOS F. 4.D-1c Same as above for Mit. Meas. 4.D-1c funding from site (Impact 4.D-2e) developer(s) Impact 4.D-3: Commerce Drive at Johnson Drive Intersection.The addition Development of vehicle trips generated by Phase I of the EDZ during the PM Less than facilitated by the peak hour would worsen the side street movement at this 4.D-la Same as above for Mitigation Measure 4.D-1a Significant proposed EDZ would intersection to LOS F;this condition would be further worsened affect levels of service with full EDZ buildout conditions. (Impact 4.D-3a) at the local study Johnson Drive at Owens Drive(North)Intersection.The intersections under addition of vehicle trips generated by Phase I of the EDZ during the Far-term Saturday peak hour would degrade the service level at this 4.0-lb Same as above for Mitigation Measure 4.D-1b Less than Cumulativeplus Significant (Cumulative) intersection from LOS C to LOS E.Conditions would be Project conditions. exacerbated with full EDZ buildout conditions.(Impact 4.D-3b) Johnson Drive at Stoneridge Drive Intersection.The addition of vehicle trips generated by full buildout of the EDZ during the Less than 4.D-1 c Same as above for Mitigation Measure 4.D 1c PM peak hour would worsen conditions at this intersection from Significant LOS D to LOS E. (Impact 4.D-3c) Stoneridge Drive(Queue Spillback).The addition of vehicle Significant and M-TR-1 Implement TDM Program trips generated by Phase I and full buildout of the EDZ would Unavoidable due to result in vehicle queue spillback from Stoneridge Drive onto uncertainty adjacent intersections and the freeway mainline.
