AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY <br /> 12956 <br />DUDEK 47 April 2022 <br />from 1946 to 2016, and historic maps available from 1906 to 2018 were inspected to observe previous <br />development in the project APE. The APE is currently undeveloped. These maps and images indicate that <br />the APE has never had any development within it. <br />On April 12, 2021, Dudek archaeologist William Burns conducted an intensive pedestrian survey of the <br />APE. Survey was consistent with Secretary of the Interior Standards. Mr. Burns inspected the ground surface <br />for cultural resources, including artifacts, features, and/or midden soils. Surface visibility within the APE <br />was low (<5% visibility) due to vegetation, with the exception of the existing informal bike trail, which is <br />highly disturbed from bike travel but allows for 100% ground visibility. No cultural resources were identified <br />during the survey (Appendix C). <br />Impact Discussion <br />a) Would the project cause a substantial adverse change in the significance of a historical resource <br />pursuant to §15064.5? <br />See Section 3.5(b), below. Impacts would be less than significant with mitigation incorporated. <br />b) Would the project cause a substantial adverse change in the significance of an archaeological <br />resource pursuant to §15064.5? <br />A records search was completed for the current project site and a 0.5-mile radius on March 25, <br />2021 (Appendix C). The records search did not identify any cultural resources within the APE. <br />Results of a Native American Heritage Commission (NAHC) Sacred Lands File search, provided <br />March 2, 2021, did not identify resources within the search area, which included U.S. Geological <br />Survey sections intersecting the project site and surrounding 0.5-mile buffer. No additional <br />archaeological or built environment resources are previously documented on the project site. One <br />cultural resource, the main clubhouse of the Castlewood Country Club, is located approximately <br />0.45 miles east of the APE. An intensive pedestrian survey conducted of the project site on April <br />12, 2021 did not identify any cultural resources. The project site is undeveloped, and surface <br />visibility within the APE is low (<5% visibility) due to vegetation. Based on observation of present <br />conditions and soil development in the area, there is a low potential for currently unidentified <br />cultural material or deposits to be encountered during project implementation and/or future use <br />of the area (Appendix C). <br />The project would have no impact to known cultural resources. However, there is a low possibility <br />for the project to inadvertently impact currently unidentified cultural resources. Archaeological <br />protection measures for potential discoveries of cultural resources are identified in MM-CUL-1. With <br />implementation of MM-CUL-1, impacts to archaeological resources would be less than significant. <br />Therefore, impacts would be less than significant with mitigation incorporated. <br />c) Would the project disturb any human remains, including those interred outside of dedicated <br />cemeteries? <br />The project site does not have any association with a cemetery or mausoleum and was not used <br />historically for burial or internment purposes. No known human remains or burial sites were
