2024-053 - Final Supplemental for The Related Bristol Specific Plan Project

Facts in Support of Findings: The proposed Project would install a new onsite water infrastructure system that would connect to water mains adjacent to the site. The proposed Project also includes offsite infrastructure improvements that would replace a portion of the 12-inch water main in South Plaza Drive from MacArthur Boulevard to Sunflower Ave with a 1 2-inch water main. The new onsite and new offsite water infrastructure would convey water supplies to the proposed residences, commercial uses, and landscaping through plumbing/'landscaping fixtures that would be compliant with the Title 24/CALG Teen Plumbing Code for efficient use of water, which would be ensured through the City's development permitting process. The proposed Project would continue to receive water supplies through the existing and improved water mains that are adjacent and near the site. This is consistent with the GPU FEIR findings that the City's water distribution system is hydraulically sound, but that due to the age and capacity of the existing water infrastructure, water main replacements would be required. Overall, the installation of new water infrastructure and improvements to offsite aged infrastructure is included as part of the proposed Project and would not result in any physical environmental effects beyond those identified throughout the Draft Supplemental EIR. For example, analysis of construction emissions for excavation and installation of the water infrastructure is included in Sections 5.1, Air Quality, and 5.5, Greenhouse Gas Emissions, and noise related to construction activities is included in Section 5.9, Noise of the Draft Supplemental EIR. Therefore, impacts related to water infrastructure would be less than significant. This is consistent with the GPU FEIR, which determined that through its planning and CIP mechanisms, the City would provide improvements to aged infrastructure to have adequate capacity for the proposed increases in water flows from buildout of the GPU, including those from buildout of the South Bristol Street Focus Area, and that impacts would be less than significant (Draft Supplemental EIR at pp. 5.15-10 through 5.15-1 1). Impact Finding: The City would have sufficient water supplies available to serve the project and reasonably foreseeable development during normal, dry, and multiple dry years (Draft Supplemental EIR at p. 5.15-1 1). Facts in Support of Findings: As shown in Draft Supplemental EIR Table 5.15-6, the proposed Project would result in a total demand of 929 AFY at full occupancy, which would be a 899 AFY increase in comparison to the water demand from the existing uses. This volume of water supply was accounted for in the City's 2015 UWMP (as determined by the GPU FEIR). Additionally, as detailed previously in Table 5.15-5, the City has an additional supply of 5,500 to 6,500 AFY beyond that anticipated to be needed by the 2020 UWMP projections. Therefore, the City would have sufficient water supplies available. Because the proposed Project would result in an increase in demand for water supplies that has been accounted for within previous City water supply planning, and separately verified through a Project specific WSA, the City would have adequate water supplies available to serve the proposed Project, and impacts would be less than significant. Therefore, impacts related to water supplies from the proposed Project are consistent with the findings of the GPU FEIR, which determined that water demand increases as a result of the GPU are within the planned supplies from the City, OCWD, and M'WD during normal -dry and multiple-
