Analysis Supporting Categorical Exemption Angeles Cleaners,located 500 feet west of the Project Site at 2525 Westminster Avenue, is a former dry cleaner in Santa Ana with known soil vapor (max 820,000 ug/m^3) and groundwater (max 388 ug/L) impacts. The site was operated as a dry cleaner intermittently between 1974 and 2012, with Angeles Cleaners being the most recent operator. Remediation has been ongoing since October 2022. A SWRCB leaking underground storage tank(LUST) remediation site is present in the shopping plaza southwest of the Project Site at Guadalajara Tire Services, located at 2501 Westminster Avenue. Remediation activities commenced in 2013 and are ongoing. A second LUST remediation site is located northeast of the Project Site at Chevron Gas Station, 2261 Fairview Street. Remedial activities commenced in 2003 and are ongoing. The Project does not involve any ground-disturbing activities that would potentially increase hazards associated with these three sites. Therefore, the Proposed Project would have no impact in this regard. (0 Historical Resources. A categorical exemption shall not be used for a project which may cause a substantial adverse change in the significance of a historical resource. ECORP conducted records searches through the California Historical Resources Information Center (CHRIS) and Native American Heritage Commission (NAHC) in November 2024 for the Project Site and Project Area(AppendixC and D).As discussed in Section 4.5 below, no historical buildings are located in the vicinity of the site and no proposed activities are planned in native, non-disturbed soils. As such, the Project would not impact unanticipated cultural resources or Historical Resources as defined by CEQA. 4.0 OTHER POTENTIAL ENVIRONMENTAL IMPACTS Cultural Resources are discussed in subsection (f) Historical Resources, above. The following overview is provided to substantiate that the Proposed Project would not result in significant impacts associated with any of the remaining CEQA topical areas as included in the CEQA Guidelines Appendix G checklist. 4.1 Aesthetics Scenic resourceswithin the Project Site include views of the San Gabriel Mountains to the north and San Bernardino Mountains to the northeast. Upon completion, the proposed roadway would not have any effect on the views of these mountains. The half-mile portion of Fairview Street would be re-landscaped but would not result in any obstruction of any important scenic view. Short-term construction activities could potentially temporarily degrade the existing visual character and quality of the site and surroundings. However, construction-related activities would be short-term and temporary in nature. Once completed, all general construction activities would cease, along with any construction-related aesthetic impacts. Therefore, the Proposed Project would not result in negative impacts to the visual character of the site. ECORP Consulting, Inc. 6 January 2025 Fairview Street Widening Project 2024-088.03 9-18
