HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR CITY OF SANTA ANA 5. Environmental Analysis HAZARDS AND HAZARDOUS MATERIALS H -8 Expose people or structures to a significant risk of loss, injury, or death involving wildland foes, including where wildlands are adjacent to the urbanized areas or where residences are intermixed with wildlands. The Initial Study, included as Appendix A, substantiates that impacts associated with the following thresholds would be less than significant: H -1, H -5, H -6, H -7, and H -8. These impacts will not be addressed in the following analysis. 5.6.3 Environmental Impacts The following impact analysis addresses thresholds of significance for potentially significant impacts. The applicable thresholds are identified in brackets after the impact statement. The term "hazardous material' is defined in different ways by different regulatory programs. For purposes of this environmental document, the definition of "hazardous material' is similar to that in the California Health and Safety Code, Section 25501: Hazardous materials that, because of their quantity, concentration, or physical or chemical characteristics, pose a significant present or potential hazard to human health and safety or to the environment if released into the workplace or the environment "Hazardous waste" is a subset of hazardous materials, and the definition is essentially the same as that in the California Health and Safety Code, Section 25517, and in the California Code of Regulations, Title 22, Section 66261.2: Hazardous wastes are those that, because of their quantity, concentration, or physical, chemical, or infectious characteristics, may either cause, or significantly contribute to an increase in mortality or an increase in serious illness, or pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, disposed of, or otherwise managed. Hazardous materials can be categorized as hazardous nonradioactive chemical materials, radioactive materials, and biohazardous materials (infectious agents such as microorganisms, bacteria, molds, parasites, viruses, and medical waste). Impact 5.6 -1: Future development that would be accommodated under the Harbor Boulevard Mixed Use Transit Corridor could create significant hazards through accidental release of hazardous materials. [Thresholds H -2 and H -31 ImpactAnalysis: The project area is in a highly urbanized, built out portion of the City. It is generally surrounded by residential uses, which vary widely in character and density and include single - family neighborhoods, apartment complexes, and mobile home communities. There are two schools adjacent to the southern boundary of the project area (Harbor Learning Center and Russell Elementary) and six schools within one- Page 5.6 -18 PlaceWorkr
