)� OCTA ISanta Ana/Garden Grove Streetcar Project Cultural Resources Technical Nlamo Update construction ofanew double -track bridge north of the historic Pacific Electric Santa Ana Riker Bridge. As part of ad van cement of engineering forth project, some TPSSsites have been refined and have resulted in the relocation of some TPSSs to publicly owned properties outside of the ROW. The proposed TPSS sites located at Harbor Blvd., Susan Street (outside of PE ROW), east side of Santa Ana River (outside of PE ROW), Pacific Avenue, in the parking structure at 5`h and Main, and on south side of Santa Ana Boulevard at Garfield Street have been consolidated and relocated. New sites for TPSS include the Civic Center Plaza and the northeast corner of Santa Ana Boulevard and North Garfield Street (Appendix A) As noted in the 2014 Cultural Resource Evaluation, the TPSS sites and passenger platforms for the projectwould be small mundane utilitarian elements intended to match the existing setting within the APE. The TPSS sites would be visuallycons istentwith other objects and equipment located along the sidewalks and ROW, such as generators and telecommunication equipment. The TPSS on Garfield Streetis within the boundaryofthe French Park Historic District, however there are no contributing resources to thatdistrict near the TPSS and the TPSS is expected to have no adverse effects on the districtor other historic properties. The relocations will result in TPSSs being located adjacent to three properties in the expanded APE that are considered eligible for the purposes of this project (Table 3). However, these TPSS would have a minimal visual intrusion to the surrounding area and would notalter the character of surrounding historic properties. Thus the relocation of TPSS will have no adverse effect on historic properties. Overall, the proposed modifications/engineering refinements to the adopted LPAwould not be considered to have an adverse effect to historic properties under NEPA, Section 106 of the NHPA, or a significant impactto historical resources under CEQA. Conclusions The updated cultural resources analysis confirms thatthe proposed engineering refinements to the projectdo notchange the previous conclusions regarding cultural resources. No adverse effects are expected within the expanded APE for the design modifications under NEPA. Under CEQA, a less than significant impact would remain the finding for the design modifications within the expanded APE. Based on the expanded 2016APE, the sensitivityof the area for archaeological resources and the recommendation for archaeological monitoring to be conducted for earth -disturbing activities thatcould encounter previouslyundisturbed soils remain unchanged and will remain consistent with the 2015 EA/EIR.
