NT MENTS INITIAL STUDYiMITIGATED NEGATIVE DECLARATION FAIRVIEW BPIOGE REVLACEM REST TO STREET BEET) PROJECT L S A MAY 2020 (9Tx STREET To ANTx STREET) L, OLEGT SANTA ANAL CALIFOPHIA d. Would the project 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? No Impact. According to the Department of Toxic Substances Control EnviroStor database,21 the Project site is not located on a federal Superfund site, State response site, voluntary -cleanup site, school cleanup site, evaluation site, school investigation site, military evaluation site, tiered permit site, or corrective -action site. In addition, the Project site is not included on the list of hazardous - materials sites compiled pursuant to Government Code Section 65962.5.22 As a result, no impacts related to hazardous -materials sites would occur. No mitigation is required. e. For a project located within an airport land use plan or, where such a plan has not been adopted, within 2 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? No Impact. The closest airport to the Project site is the John Wayne Airport, which is located approximately 6.6 mi southeast of the Project site; however, the Project site is not located within the Airport Land Use Plan. The proposed Project's operation would be similar to the existing conditions. Because the Project area is not located within an Airport Land Use Plan, the proposed Project would not involve the introduction of residential or employment uses in the Project area, the proposed Project would not significantly change the roadway from existing conditions, and the proposed Project would result in no impacts related to aviation -related safety hazards or excessive noise for construction workers or travelers using the bridge or SART. No mitigation is required. f. Would the project impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Less Than Significant with Mitigation Incorporated. Fairview Street would remain open during the construction period (at least one lane with a pedestrian/bicyclist area); northbound and southbound traffic would be shifted to one side of the bridge while the other side is replaced. Access to properties would be maintained. However, construction activities may temporarily restrict local vehicular traffic, which could affect emergency response or evacuation. There are no local adopted emergency responses or emergency evaluation plans applicable to the Project area. A Traffic Management Plan (TMP) is needed to ensure that adequate emergency response and evacuation will be maintained. Mitigation Measure TR-1, provided later in Section 3.17, Transportation, requires that a TMP be developed during final design to address impacts to local circulation during construction, including emergency access. The TMP would require that emergency service providers be notified prior to Project construction regarding any temporary limitations to emergency access. Therefore, with implementation of Mitigation Measure TR-1, potential impacts to emergency response and evacuation plans during construction would be reduced to less than significant. 21 California Department of Toxic Substances Control. 2019.
