Santa Ana — Gardon Grove Fixed Guideway Project Findings and Facts in Support of Findings and Statement of Overriding Considerations L. Noise (pages 3 -152 and 3 -207 of the EA/DEIR) • Regarding operational vibration, the maximum vibration level generated by the proposed project would be 70 VdB at a streetcar speed of 40 miles per hour and would not exceed Federal Transit Administration (FTA) vibration impact criteria of 72 VdB for residential land uses. For institutional land uses, the maximum vibration level would be 74 VdB at a streetcar speed of 35 miles per hour and would not exceed FTA vibration impact criteria of 75 VdB. Operational activity would not expose people to excessive vibration levels. Therefore, a less- than - significant impact related to vibration would occur. • The proposed project would generate construction - related noise and vibration. Alignment and bridge construction activities would employ pieces of equipment (i.e., mounted impact hammer, foundation driller, pneumatic tools, concrete pump truck, and pavement miller or scarifier) that would exhibit high noise and vibration levels. A Noise and Vibration Control Plan will be developed and implemented prior to construction that will include BMPs to minimize exposure to high levels of noise and vibration and ensure compliance with City and FTA standards. With implementation of the Noise and Vibration Control Plan described in Section 3.16.2.3 of the EA /DEIR, the proposed project would not conflict with applicable noise standards and would not generate excessive vibration. Therefore, a less -than- significant impact related to construction noise and vibration would occur. • The closest public airport within the Study Area is John Wayne Airport, located approximately four miles to the southeast, and is not within the impacted airport noise level contours. Therefore, no impact related to airport noise would occur. M. Population and Housing (page 3 -28 of the EA/DEIR) • The proposed project would require housing acquisition resulting in displacement of approximately 28 persons. In addition, acquisition would affect fewer than a dozen businesses, which would displace no more than 50 jobs. Due to the small amount of housing and business displacement (less than one percent of the Study Area population), the number of persons displaced would be minimal compared to the existing population. Therefore, a less- than - significant impact related to population would occur. • Given the length of the four -mile alignment and the City of Santa Ana's population of over 58,000 within the Study Area, the displacement of 28 people (less than 0.05 percent) would not be considered substantial. Acquisitions requiring the displacement of existing residential uses would comply with the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 (Uniform Act). The proposed project would provide relocation assistance and compensation to displaced residences per the Uniform Act. Compensation would not be less than the approved appraisal of the property. Therefore, the proposed project would not result in the displacement of substantial housing, and a less -than- significant impact related to housing would occur. N. Public Services (page 3 -62 of the EA/DEIR) • The proposed project would not introduce a new population to create additional demand for police and fire services. The proposed project is not anticipated to create additional demand 14 January 2015
