Harbor Boulevard Mixed Use Transit Corridor Plan Findings and Facts in Support of Findings and Statement of Overriding Considerations Facts in Support of Finding Mitigation Measures 2 -1 and 2 -2 would reduce the project's regional construction emissions and therefore also reduce the project's localized construction- related criteria air pollutant emissions to the extent feasible. However, because existing sensitive receptors may be close to project - related construction activities, construction emissions generated by individual projects have the potential to exceed SCAMQD's localized significance thresholds. Therefore, this impact would remain significant and unavoidable. Mitigation Measures Mitigation Measures 2 -1 and 2 -2 apply to this impact. (4) Potential Impact: The Harbor Boulevard Mixed Use Transit Corridor Plan could site sensitive land uses in proximity to major air pollution sources. Finding: 1. The City makes Finding 1 and determines that this impact is less than significant with the implementation of the proposed mitigation measure Facts in Support of Finding The proposed project would result in construction of up to 3,884 new residential units within the Harbor Boulevard Mixed Use Transit Corridor Plan boundaries at buildout. The exact locations of new sensitive land uses are not known at this time, although residential uses would be allowed near existing onsite light industrial land uses in the interim period until these industrial sites transition into new land uses. In addition, residential uses would also be allowed near existing offsite light industrial land uses. Light industrial land uses with sources of toxic air contaminants have the potential to affect new sensitive land uses within the Harbor Boulevard Mixed Use Transit Corridor Plan. Adherence to Mitigation Measure 2 -10 would ensure that new residential land uses proximate to major sources of toxic air contaminants reduce risk by installing high- efficiency MERV filters to reduce indoor concentrations particulates (including diesel particulate matter, which comprises the majority of risk) below SCAQMD's threshold. With implementation of Mitigation Measure 2 -10, this impact would be less than significant. Mitigation Measures MM 2 -10 Applicants for residential or residential mixed -use projects within: 1) 1,000 feet from the truck bays of an existing distribution centers that accommodate more than 100 trucks per day, more than 40 trucks with operating transport refrigeration units, or where transport refrigeration unit operations exceed 300 hours per week; or 2) 1,000 feet of an SCAQMD permitted facility, or an industrial facility which emits toxic air contaminants shall submit a health risk assessment (HRA) prepared in accordance with policies and procedures of the state Office of Environmental Health Hazard Assessment (OEHHA) and the South Coast Air Quality Management District ( SCAQMD). 24 July 2014
