)� OCTA I Santa Ana/Garden Grove Fixed Guidew ay Project <br />Cultural Resources Technical Nlamo Update <br />Area of Potential Effects (APE) <br />The 2015 APE was originally created to take into consideration both archaeology and <br />architectural resources, encompassing the maximum footprint for construction, ground - <br />disturbance and grading, and generallyextended one parcel pastthe limits of the above -ground <br />project improvements, and/ordirect impacts for the TPSS sites, gated crossings, tree removal <br />areas, maintenance facilities, transit structures, raised medians, staging areas, property <br />acquisitions, and ROWimpacts. The APE also included previouslyrecorded cultural resources <br />located adjacentto the above -ground project improvements and direct impact areas. In addition, <br />the APE included parcels adjacentto the proposed project footprint as part of the architectural <br />historyfield surveys for propertiesthat maybe potentially indirectly affected byvisual, audible, <br />or atmospheric intrusions; shadow effects; vibrations from construction activities; or change in <br />access or use. These areas of the APE would not be physically demolished, destroyed, <br />relocated/removed, materia Ilya ltered, orimpacted from neglect ordeterioration as a result of <br />this project. <br />The original projectAPEwas compared to the minordesign modifications to the adopted LPA, <br />and a revisedand expandedAPEwas developed to addressthe modifications (see Appendix <br />C). The revised APE encompasses the original 2015 APE and was expanded in areas to <br />accommodate minordesign modifications, primarilyto include the relocation of TPSS, areas of <br />ground disturbance due to utility relocations and storm drain improvements, adjustments to <br />platforms, station stops, and rail lines, and the location ofthe bridge over the Santa Ana River. <br />The APE maps include the locations of historic properties. In keeping with the previous <br />methodology, both directand indirect effects were taken into accountwhen revising the APE <br />and include areas where the streetcar and its project components will be visible and/or where <br />there may be effects due to audible or atmospheric impacts or vibration impacts from <br />construction. <br />Identification of Historic Properties <br />An updated records search was conducted with the South Central Coastal Information Center to <br />ensure that all recently recorded cultural resources in the expanded APE were taken into <br />accountin the currentstudy(seeAppendix D). The areas of the expanded 2016 APE do not <br />include any newly identified historic properties since the 2014survey, and whatwas included in <br />the 2015APE.A reconnaissance -level field surveywas conducted in May2016 to photograph <br />and documentthe expanded areas of the revised APE. Surveyphotos ofkeyproperties and <br />photo key maps are included in Appendix E. <br />As noted in the 2014 surveyand evaluation, there are several historic properties located with <br />the 2015APE. The proposed modifications refinements and the expanded APE include the <br />historic properties identified in Table 2. There are no known archaeological or paleontological <br />resources eligible for listing in the NRHP located within the original or expanded APE. <br />July 8, 2016 1 10 <br />
