emissions generated for each project would vary depending on its size, the land area that would need to be disturbed during construction, and the length of the construction schedule. Under these conditions, no further feasible mitigation measures are available and this impact would be considered significant and unavoidable. The City will make site -specific determinations of significance during the review of these individual development projects to determine which projects for which construction emissions may exceed significance thresholds. For the purpose of analysis in this EIR, a programmatic level of analysis is provided for the proposed development under the Overlay Zone. The Overlay Zone would develop 5,400 residential units, a total of 1.1 million square feet of commercial space, and 1.7 million square feet of office uses by the year 2030. As the Overlay Zone has the potential to exceed SCAQMD's recommended thresholds of significance and results in short-term air quality impacts, the impact of the Overlay Zone is anticipated to be significant. Mitigation Measures MM-OZ 4.2-2 through MM-OZ 4.2-13 shall be implemented where appropriate. In addition, emission levels of VOCs, which are a precursor for ozone, would likely exceed SCAQMD significance thresholds during the application of architectural coatings (paint and primer) for the Overlay Zone. In order to reduce the VOC emissions levels associated with architectural coatings, Mitigation Measures MM-OZ 4.2-14 through MM-OZ 4.2-16. However, because construction emissions for an individual project typically exceed the SCAQMD's recommended thresholds of significance and results in short-term air quality impacts, the impact of the Overlay Zone, which takes into consideration the construction emissions generated from all of the development proposed under the Overlay Zone, were determined to be significant and unavoidable. Operation The Certified EIR stated that operational emissions generated by both stationary and mobile sources would result from normal day-to-day activities on the project site after occupation. Stationary, area source emissions would be generated by the consumption of natural gas for space and water heating devices, and the operation of landscape maintenance equipment. Mobile emissions would be generated by the motor vehicles traveling to and from the Overlay Zone. The analysis of daily operational emissions from the Overlay Zone has been prepared utilizing the URBEMIS 2002 computer model recommended by the SCAQMD. In terms of operational emissions, the Overlay Zone would incorporate certain features in its design that would help reduce the operational emissions that would otherwise be generated by the Overlay Zone. These design features include the following: • Street lighting to provide safety along pedestrian routes • Shade trees to shade sidewalks to encourage use by pedestrians The Overlay Zone's design features would encourage pedestrian activity, which would reduce the emissions from the operation of motor vehicles by project employees and residents.
