Impact 5.2 -6 Mitigation measures applied for Impact 5.2 -1 and Impact 5.2 -2 would reduce the project's regional construction related and operational phase criteria an pollutant emissions to the extent feasible. 5.2.8 Level of Significance After Mitigation Impact 5.2 -1 Mitigation Measures 2 -1 through 2 -3 would reduce criteria an pollutants generated from project- related construction activities. Buildout of the Harbor Boulevard Mixed Use Transit Corridor Plan would occur over a period of approximately 20 years or longer. Construction time frames and equipment for individual site specific projects are not available. There is a potential for multiple developments to be constructed at any one time, resulting in significant construction related emissions. Therefore, despite adherence to Mitigation Measures 2 -1 through 2 -3, Impact 5.2 -1 would remain significant and unavoidable. Impact 5.2 -2 Incorporation of Mitigation Measures 2 -4 through 2 -9 would reduce operation related criteria an pollutants generated from stationary and mobile sources. Mitigation Measures 2 -5 through 2 -9 would encourage and accommodate use of alternative fueled vehicles and non motorized transportation. However, despite adherence to Mitigation Measures 2 -4 through 2 -9, Impact 5.2 -2 would remain significant and unavoidable. October 2014 Page 5.2 -27
