Approximately 300 cubic yards of debris would be generated by the proposed project, consisting of lumber, Styrofoam blocks and some pressure treated wood. It is estimated that approximately 40 truck trips would be required to transport the material from the project site to the City’s Corporation Yard, approximately 1.1 miles from the project site. Approximately 3 to 4 semi-trailer truck trips would be required to transport the material from the City’s Corporation Yard to the Ox Mountain Landfill, approximately 20.6 miles away. However, as a conservative assumption this analysis utilized model default construction trips, which assume 3 one way hauling trips per day and a distance of 20 miles. Construction-related emissions are presented in Table B. CalEEMod output sheets are included in Attachment A.

No No No N/A No N/A Source: LSA (November 2024). BMP = best management practices As shown in Table B, construction emissions associated with the project would be less than significant for ROG, NOx, and PM2.5 and PM10 exhaust emissions. For a project to have a less- than-significant criteria air pollutant impact related to construction-related fugitive dust emissions, it must implement BAAQMD’s basic construction best management practices (BMPs), whether or not construction-related emission exceed applicable thresholds. These BMPs have been incorporated into project description and would be implemented during project construction. After deconstruction, the proposed project would not result in a significant increase in the generation of vehicle trips or vehicle miles traveled that would increase air pollutant emissions as there is no construction or other operational phase of the project proposed after the deconstruction work. The project would also not be a source of stationary source emissions. Therefore, construction and operation of the proposed project would not result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or State ambient air quality standard and impacts would be less than significant. Since the proposed project would not result in significant construction- or operation-related air quality impacts, the proposed project would not conflict with applicable air quality plans and would not expose sensitive receptors to substantial pollutant concentrations. In addition, because there is no construction or other operational phase of the project proposed after the 6.G. - Page 19 of 45 197
