City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update CEQA Findings of Fact and Statement of Overriding Considerations FirstCarbon Solutions 87 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/FOF/21480022 Pleasanton Housing Element FOF.docx Conditions of Approval prior to issuance of grading or building permit, whichever is sooner. Outdoor Air Quality–Individual and common exterior open space, including playgrounds, patios, and decks, shall either be shielded from the source of air pollution by buildings or otherwise buffered to further reduce air pollution for project occupants. Facts in Support of Findings: The current AQP applicable to the Housing Element Update is the 2017 Clean Air Plan. A proposed land use plan is consistent with the AQP if it would (1) support the primary goals of the AQP, (2) include applicable control measures from the AQP, (3) not disrupt or hinder implementation of any AQP control measures, and (4) the plan’s projected VMT increase must be less than or equal to its projected population growth. 1. The Housing Element Update Supports the Primary Goals of the AQP: The primary goals of the 2017 Clean Air Plan are to (1) attain air quality standards, (2) reduce population exposure and protect public health, and (3) reduce GHG emissions and protect the climate. Attain Air Quality Standards: Long-term criteria pollutant emissions would result from the operation of potential residential uses facilitated by the Housing Element Update. Operational air quality emissions are principally generated from area sources, energy sources, and mobile sources. The method for determining whether a project or plan supports the goals of the AQP is to determine whether that project or plan is consistent with a BAAQMD- approved CEQA threshold of significance. The BAAQMD determines a plan, such as the Housing Element Update, to result in an exceedance of recommended significance thresholds if a plan facilitates growth in VMT that exceeds the growth in population over that same time. The Housing Element Update would result in population growth which outpaces forecasted VMT growth, and thus the Housing Element Update would not result in an exceedance under this criterion. In measuring whether an individual development project would have potentially significant impacts on local and regional air quality, including consideration of an individual development project’s contribution to an existing or forecasted air quality violation, the BAAQMD recommends project-level significance thresholds for criteria pollutants and ozone precursors. Considering the BAAQMD’s recommended significance thresholds and that the SFBAAB is currently in nonattainment for PM standards, individual development projects facilitated by the Housing Element Update would be considered to have potentially significant site-specific or project-specific impacts related to the generation of fugitive dust during construction activities if they do not implement BMP targeting dust control and sediment migration. Therefore, Mitigation Measure (MM) AIR-1a, which would require individual development projects to employ dust control measures recommended by the BAAQMD during construction, would ensure that all future development projects facilitated by the Housing Element Update would not result in potentially significant impacts related to construction fugitive dust and contribute to the region’s current nonattainment status for PM.
