The Stoneridge Drive Specific Plan established a number of public infrastructure improvements to be constructed as development occurred. These improvements were identified and evaluated in the original project EIR and included as part of the Specific Plan. Costs were based upon a pro-rata share of their developable acres within the Specific Plan area. The infrastructure improvements identified were the I-580/El Charro Road interchange, El Charro Road, flood control, Stoneridge Drive, Stoneridge Drive bridge and park improvements. Since the adoption of the Stoneridge Drive Specific Plan in 1989, several factors have contributed to changes in the infrastructure improvements expected to be constructed. These are a reduction of the El Charro Road improvement costs due to the elimination of the truck underpasses, an increase in the scope of the flood control improvements, reduction of the ultimate El Charro Road plan to four lanes from Stoneridge Drive south to the Arroyo. The assigned pro-rata share of the total improvements will not change. Kaufman and Broad will be constructing a large share of the total improvements. The remaining Specific Plan improvements will occur as the remainder of the Chu property is constructed. These developers will either contribute funds or construct improvements in accordance with the Plan. Kaufman and Broad will also be constructing the realigmnent of Friesman Road in Livermore, performing flood control work in Livermore in order to complete the flood control improvements in Pleasanton, constructing a pedestrian bridge at the end of Martin A venue over the Arroyo Mocho, and dedicating and improving an additional 16 acres of parkland. All of these improvements benefit the public and benefit the Specific Plan developments. Should there be any funds available in the Specific Plan after all developments have been constructed and/or all improvements installed according to the amended Plan, staff recommends that these funds be disbursed to the residential developer (K&B). ~ The phasing of the improvements which the applicant will make is fairly complex. Infrastructure improvements and the phasing for in-tract improvements and home construction will be occurring continuously. Permits for channel work allow work only between April 15 and October 15. It is the applicant's intent to construct the Martin Avenue pedestrian bridge as soon as possible and it is the City's desire that the bridge be installed prior to the beginning of the 1997/98 school year. The developer has indicated that construction of the sports park would be a priority; it may be that the park would need to be constructed in phases corresponding to residential development. The Commission is required by State CEQA Guidelines to review the document for adequacy and completeness before making a decision on the proposed project. The Commission also must decide that all the mitigation measures of the EIR reduce to a less than significant level those impacts which have been identified as significant or potentially significant, or adopt a Statement of Overriding Consideration for any impact which cannot be reduced to a less than significant level. There is only one potentially significant impact--freeway traffic noise levels in outdoor multiple family residential areas--which cannot be mitigated to a less than significant level. In conclusion, staff feels that the proposed amendment to the Specific Plan is appropriate given the changes in circumstances which would allow additional residential development and given the benefits the amendment would provide for the Pleasanton community. The proposed location of the residential area, on the periphery of existing residential development, is consistent with the policies of the General Plan. Staff feels that the expansion of the adopted park area to almost 34 acres is of Planning Commission Minutes Page 17 February 12, 1997
