assumes the Concurrent Extension and approximately twice as many trips as the Project. The Concurrent Extension, like the Deferred Extension, would generate fewer trips than assumed in the adopted air quality plan and, consequently, would result in growth and local traffic congestion at levels below the baseline assumed by the adopted air quality plan. Revising the Project to include the Concurrent Extension would, therefore, just as with the Deferred Extension, result in a less than significant impact to applicable air quality plans. While the Ice Center Alternative would generate more trips than the Project, the 1989 Stoneridge Drive Specific Plan would still generate more than 1.5 times as many trips. The Ice Center Alternative with the Concurrent Extension would, therefore, still result in a less than significant impact to applicable air quality plans. B. Impact AQ-2. Short-term air quality emissions. The Draft EIR concludes that, with the Deferred Extension, the Project will result in less than significant short-term air quality impacts after mitigation. (Impact AQ-2, Draft EIR, page 3.2-12.) The construction of two additional lanes of Stoneridge Drive as part of the Project with the Concurrent Extension would generate slightly more construction-related emissions than with the Deferred Extension. However, the dust control measures of mitigation measure AQ-2.1 would apply to reduce the additional impacts of the Concurrent Extension to a less than significant level. C. Impact AQ-3. Regional emissions. The Draft EIR concludes that, with the Deferred Extension, the Project will result in significant and unavoidable regional emission impacts after mitigation. (Impact AQ-3, Draft EIR, page 3.2-13.) The regional emissions analysis of the Draft EIR is based on the trip generation rates of the project, which will not change with the Concurrent Extension. Regional emissions impacts therefore will remain significant and unavoidable under the Concurrent Extension, as with the Deferred Extension. The Concurrent Extension may change traffic patterns through the project site at an earlier date, but it does not cause an increase in the absolute number of sources contributing to regional emissions. D. Impact AQ-4. Localized carbon monoxide air quality impacts. The Draft EIR concludes that, with the Deferred Extension, the Project will result in less than significant localized carbon monoxide air quality impacts. (Impact AQ-4, Draft EIR, page 3.2-16.) The Draft EIR arrived at this conclusion based on an analysis of localized carbon monoxide air quality impacts at select representative intersections under 2015 conditions that assumed the Concurrent Extension (See Note "a" to table Stoneridge Drive Specific Plan Amendment and Staples Ranch Project Environmental Impact Report Findings and Statement of Overriding Considerations Pagc IS of47
