Prewous model runs presented "unmitigated" results. For this report, intersection mitigation measures were explored for the previous "Existing Plus Approved, Year 2010" model run and for the new "buildout" model run. This information has been included to show types of mitigation measures which can be used and to prepare the City Council and Planning Commission for future discussions on this topic. Table 6, which includes the mitigation measures, was included with this report to allow the City Council and Planning Commission the opportunity to ask questions about how the data is presented, and discussion about mitigation measures will occur at the next workshop. Note that the mitigations do not include the Stoneridge Drive Extension or the West Las Positas Boulevard Interchange. At the last workshop, the Council also asked for information relating to potential residential development under the existing General Plan and voter-approved housing cap and for information about State legislation affecting a city's ability to lower planned residential densities. These issues are also addressed in this report. "EXISTING PLUS APPROVED, YEAR 2025" BASELINE MODEL Prior model runs reported to the Council included the short-term future "Existing Plus Approved, Year 2010" scenario and the "General Plan Buildout" scenario. The new baseline model combines elements of both of these and depicts traffic conditions assuming no growth in Pleasanton beyond approved development but with buildout of our neighboring cities' general plans and with Year 2025 regional traffic growth. This baseline is designed to address Council's request for a starting point with no growth in Pleasanton beyond that which already has discretionary approvals (development agreements, tentative maps, final design review) but with development around Pleasanton as currently planned by other jurisdictions. Year 2025 regional growth is assumed throughout the nine-county Bay Area based on the latest projections available. Staff believes it is unlikely, but possible, for other jurisdictions to reach their buildout by 2025, but full buildout of these jurisdictions was assumed. As for any projection, land uses have to be frozen in time, and the build-out numbers for adjoining cities reflects current general plans. It does not assume development in North Livermore (a ballot initiative for November) nor modifications to the East Dublin plan (application for intensification submitted). Table 1 below describes the assumptions of the various model runs. SR 05:135 Page 2
