ENVIRONMENTAL IMPACT REPORTADDENDUM Bristol Street Widening Project Warner Ave to Saint Andrew Place (Phase IV) TABLE 8 LOCAL SCHOOLS WITHIN THE PHASE IV PROJECT AREA Sa=6 I L Oi. " CSx4"'Cx;p' 3' K{i4 V' C L"'IY'r'L 5^ W'.2C' 3 3r't C'Ti -`'H" Jose Andres Sepulveda 1801 S Poplar Street, Santa Ana, CA West of Bristol Street at Saint0,11 miles Elementary School 92704 Andrew Place intersection 1202 West Edinger Avenue, Santa Ana, Northeast of Bristol Street at Saint Mater Del High School 0.25 miles CA 92707 Andrew Place intersection Hazardous materials can be classified into four basic categories: toxins, flammables, irritants, and explosives. Toxins include a broad range of industrial chemicals and agricultural pesticides that may cause serious illness or death to humans. Irritants can cause inflammation or destruction of living tissue with effects ranging from mild to severe, depending on the degree of exposure and material involved. Flammables pose the threat of combustion at low ignition temperatures and rapid burning characteristics. Explosives can produce rapid chemical reactions causing damage from blast and flash fire. Because of their widespread use, it was assumed that each type of hazardous material was transported through, used, or stored to some degree, within the project area. Storage and use of hazardous materials was, and still is, generally limited to the industrial area to the west although hazardous materials are used or stored along Bristol Street at businesses such as gas stations, auto service shops, metal polishing and plating operations, and medical clinics. Both Mater Dei High School and Jose Andres Sepulveda Elementary School were identified and evaluated for potential impact in the 1990 Final EIS /EIR. It is not anticipated that the project would increase risk of upset beyond previous conditions. Therefore, health risks associated with project construction activities would be less than significant and impacts are not greater than previously analyzed in the 1990 Final EIS /EIR. Mitigation Measures No new additional mitigation measures are required. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? The proposed project site involves the widening of an existing intersection. The project area is developed with commercial and retail uses. Compliance with existing regulations and mitigation measures from the 1990 Final EIS /EIR would ensure that impacts are not greater than previously analyzed in the 1990 Final EIS /EIR. Mitigation Measures No new additional mitigation measures are required. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? The project site is not within an airport land use plan. The closest airport to the site is John Wayne — Orange County Airport, miles southeast of the project site. The proposed widening would not introduce any new risks or increase risks associated with the project. ANA 305 -194 (PER 02) CSA (AUGUST 2014) 133867 YU 75C -54 38 City Council 17 – 193 3/4/2025
