ARROYO LAGO RESIDENTIAL PROJECT ADDENDUM 74 FCS Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480036/Addendum/21480036 Arroyo Lago Residential Project Addendum.docx addressed. It also provides the local agency with ongoing information as to whether they are contributing to the clean air goals in the 2017 Clean Air Plan. The proposed project would result in the construction of 189 single-family houses, 48 junior ADU’s, and related improvements on approximately 30 acres. Demographics trends such as employment and population growth were estimated in the Association of Bay Area Government (ABAG) Plan Bay Area 2040 based on local general plan land use patterns, which the Bay Area Air District utilized in part to inform the emissions inventory and projections contained in the 2017 Clean Air Plan. Currently, the project site has a County land use designation of MDR, which serves as the land use basis for the Bay Area Air District’s emissions inventory and projections in the 2017 Clean Air Plan. The proposed project would be consistent with the Bay Area Air District’s projections. The 2017 Clean Air Plan also contains control measures required by the Bay Area Air District to reduce emissions for a wide range of stationary and mobile sources. As described above, the Prior FEIR determined that the County Project would be consistent with the applicable control measures in the 2017 Clean Air Plan, including those related to stationary source emissions, transportation, energy and climate, buildings, natural working lands, waste management, water, and GHG emissions after incorporation of MM AIR-1. The proposed project would be largely the same as the County Project, only with fewer proposed dwelling units and the elimination of a substantial amount of off-site utility improvements. As such, the proposed project would also be consistent with the applicable control measures with implementation of MM AIR-1, including those related to waste management, water control, and energy, if not to a greater extent. Given the slightly reduced unit count and the elimination of substantial off-site utility improvements, the proposed project emissions would result in similar or fewer emissions than what were analyzed in the Prior FEIR, which were already below the Bay Area Air District’s significance thresholds. Therefore, potential impacts would be considered less than significant, consistent with the analysis in the Prior FEIR. Regarding impacts related to construction fugitive dust, the Bay Area Air District requires that a project implement construction BMPs, which would ensure that impacts would be less than significant. Therefore, similar to the County Project and Alternative 2, MM AIR-1 would still be required to ensure implementation of construction BMPs recommended by the Bay Area Air District. Because of reduced unit count and elimination of substantial off-site utility infrastructure, combined with adherence to applicable control measures in the 2017 Clean Air Plan and the implementation of MM AIR-1, the proposed project would not result in any new or more severe significant impacts related to conflicts with implementation of the 2017 Clean Air Plan beyond what was analyzed in the Previous FEIR. Therefore, the proposed project would not introduce new significant impacts or create substantially more severe significant impacts than those previously identified in the Prior FEIR. No additional analysis is required.
