reduction in number of homesites, peak hour trips would be approximately 16% to 18% less than the Original Project. This reduction would, however, generate the same general impacts, and would require the same mitigation measures as the Original Project. Alternative 3 -Transportation Alternative Description Alternative 3 would provide a second public road access in addition to that provided by Hearst Drive into the site. The route would be toward the north through the Berlogar property to a connection with New Vineyard Avenue. The rationale for this alternate access road is that it could reduce project traffic on Bernal Avenue. This alternative is identical to the Original Project in that it would situate 98 homes on the 562 acre site. It differs from the Original Project only in the provision of this supplemental access route. Finding: Infeasible The traffic analysis evaluating this second-road-access alternative concluded that the alternative would not be successful in diverting enough project traffic to have a substantial effect in reducing future congestion in Pleasanton's road network. Thus, because Alternative 3 would not effectively serve the principal purpose for which it was formulated, it was not subjected to an environmental analysis at the same level of detail as the site plan alternatives. If it had been, it is reasonable to believe that it would be found to have a number of environmental impacts -including impacts on biological resources, hydrology and drainage, geology -the stability of the alternate access route in an area of mapped landslides, and noise that are greater in geographic extent or magnitude than the impacts of the Original Project and the other land use alternatives. Alternative 4 -Environmentally Superior Alternative Description Alternative 4 would reduce the number of lot from 98 to 51. The lots would be situated generally along streets that are generally similar in alignment to Street "A" and Courts "1" through "4" in the Original Project. Lot sizes in Alternative 4 would range from 30,290 square feet to 90,834 square feet, with an overall average of about 48,460 square feet. Two balance fill areas would be established for the placement of excess soils generated from grading the roads and lots. This alternative is similar to the Original Project, but differs from the Original Project in the following ways: Page 6 of 43
