Assessing Effects of the Minor Design Modifications <br />The track shift discussed above (#1) occurs within the existing APE and there are no previously <br />identified cultural resources in the area east of the SAR Bridge. As such, this proposed design <br />modification does not directly or indirectly affect the existing cultural resource findings since it will <br />not have a visible and/or audible or atmospheric impact or vibration impacts from construction on <br />any previously identified historic property, nor necessitate a change in the APE. <br />The change of TPSS location discussed above (#2) is to a new location within the existing APE <br />limits (within APN 398-351-04, Sheet 15 of 15 of the APE map; also see Figure 1). The TPSS <br />sites for the Project are small mundane utilitarian elements intended to match the existing setting <br />within the APE. The TPSS 4 site would be visually consistent with other objects and equipment <br />located along the sidewalks and ROW, such as generators and telecommunication equipment. <br />Since TPSS 4 will be constructed within an existing parking lot at the modern SARTC facility, it <br />will not have a visible and/or audible or atmospheric impact or vibration impact from construction <br />on any previously identified historic property. Therefore this change in location does not <br />necessitate a change in the APE. <br />Figure 1. Proposed new location of TPSS 4 at the SARTC, just north of the parking structure. <br />The proposed Project footprint modifications and anticipated revised construction limits <br />(described in #3 above) associated with paving, striping, signing, curb ramp and driveway <br />approach improvements, as well as the area for trenching related to drainage improvements and <br />utility connections are limited to areas within the public ROW. Since the work proposed is <br />temporary in nature, and would not require acquisition or physical alterations with any surrounding <br />historical properties, the only potential for an adverse impact to occur during construction would <br />result from indirect vibration effects that cause physical damage to historic structures. There have <br />
