PC-2009-14, DRAFT PLEASANTON GENERAL PLAN

The intersection of Stoneridge Drive at Johnson Drive, while still failing in LOS, would operates at LOS E in the Dispersed Growth Alternative instead of LOS F in the proposed General Plan. The mitigation to return Stoneridge Drive at Johnson Drive from LOS E to an acceptable level of service is the same mitigation as in the proposed General Plan (see TR -1-24 on page 3.4-22.) Two One intersections, West Las Positas at Coronado Lane and Stoneridge Drive at El Charre would operate at an acceptable level of service in the Dispersed Growth Alternative but not in the proposed General Plan, prior to miti ag tion... . On page 5-20 of the DEIR, the second paragraph under transportation has been modified as follows: The discussion below is based on a level -of -service analysis for all intersections prior to the inclusion of mitigation measures. As part of this alternative, potentially significant effects due to level of service would be mitigated for all intersections that are not located in the Downtown or atag tewgy locations. The Concentrated Residential/Mixed Use Alternative, assuming the ITE data, would result in Ay -19 intersections operating at an unacceptable level of service. Comparing this alternative with the proposed General Plan shows that six -five intersections would operate at a level of service worse than, and having delays greater than, the proposed General Plan, and one intersection would change from an unacceptable operation level to acceptable. Of the six -five, twee -two are located within the Downtown and are exempt from operating at LOS D or better, and therefore would not require measures to mitigate the impacts. One intersection is a gateway intersection and, as wit the proposed General Plan, would not be required to improve its operation to LOS D or better. Thisatg eway intersection (East Bound I-580 off -ramp to Santa Rita Road) could result in a new potentially significant effect that may not be mitigated. Two other intersections would need include the following additional mitigation measures to improve conditions to an acceptable LOS. Table 5-10 on page 5-21 of the DEIR has been changed to delete the Stoneridge Drive at El Charro Road intersection, the last intersection listed on the table. On page 5-22 of the DEIR, the fourth paragraph has been modified as follows: Intersection operations for the other study intersections would generally operate under similar conditions with either the Concentrated Residential/Mixed Use Alternative or the proposed General Plan. As such, the Concentrated Residential/Mixed Use Alternative would result in greater impacts than would occur under the proposed General Plan with one more intersection resulting in a potentially significant impact than the project. CHANGES TO THE RESPONSES TO COMMENTS DOCUMENT Chapter 5 On page 5-7, the third paragraph has been modified as follows: Pages 3.2-21 and 22 the mitigation measures after TR -1.1 are revised as follows (Response to Comments 5.1 and 23.
