ONE BROADWAY PLAZA PROJECT EIR ADDENDUM CITY OF SANTA ANA 5. Environmental Analysis State, and local laws and regulations regarding hazardous waste. The Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effect and would not require the preparation of a subsequent EIR. 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? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. The Phase I ESA prepared for the Approved Project determined that there are no unusual hazardous conditions at the Project Site. A review of the State Water Resources Control Board's Geotracker and the Department of Toxic Substances Control's EnviroStor databases indicate that there are no cleanup sites on the Project Site (SWRCB 2020, DTSC 2020). Further, a review of US Environmental Protection Agency's EJSCREEN mapping tool shows no hazardous waste sites on the Project Site (USEPA 2019). The Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effect and would not require the preparation of a subsequent EIR. 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 or excessive noise for people residing or working in the project area? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. As discussed in the Certified EIR, the Approved Project would be required to comply with FAA regulations and file Form 7460-1 for buildings exceeding 200 feet in height. The Proposed Project would not increase the height of the Approved Project nor add new building area. Therefore, this impact would remain less than significant and the Proposed Project would not create a new significant impact or a substantial increase in the severity of previously identified effect and would not require the preparation of a subsequent EIR. f) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. The Initial Study for the Approved Project states that there are no designated emergency evacuation routes in the City. The Public Services Section of the Certified EIR determined that the Approved Project would incorporate fire access roadway requirements of the California Fire Code. For the Approved Project, SAID required an additional traffic signal at the intersections of Broadway Street and 10th Street, Broadway Street and Washington Avenue, and Sycamore Street and Washington Avenue as well as any intersection updates to accommodate traffic for the Approved Project. Since these intersections are already signalized an emergency vehicle preemption detector can be installed as part of the Approved Project (refer to Mitigation Measure PS- 8 below). Further, as discussed in Section 5.15, Public Services, the Proposed Project would implement all identified mitigation measures which would ensure that the Proposed Project would result in a less than significant impact to police protection and fire and emergency services. These mitigation measures would further ensure that the Proposed Project would not impair the implementation of an emergency response plan. This impact would be less than significant, and the Proposed Project would not create a new significant impact Page 60 PlaceWorks
