previously been found in the project vicinity. California law recognizes the need to protect historic era and Native American human burials, skeletal remains, and items associated with Native American interments from vandalism and inadvertent destruction. The procedures for the treatment of Native American human remains are contained in Sections 7050.5 and 7052 of the California Health and Safety Code and in PRC Section 5097. It is possible that previously unknown buried human remains could be unearthed and damaged or destroyed during excavation activities associated with the proposed project, such as grading,preparation, and use of staging areas, excavation, and stockpiling. Damage to or destruction of human remains during project construction or other project-related activities would be considered significant. Because there is potential for such damage to occur,this impact would be potentially significant. 4.12.3 MITIGATION MEASURES No mitigation measures are necessary for the following less-than-significant impact: 4.12-1. Damage to or Destruction of Documented Cultural Resources. The following mitigation measures are provided for the potentially significant impacts of Impacts 4.12-2 and 4.12-3: Mitigation Measure 4.12-2: Damage to or Destruction of Undiscovered Cultural Resources. Before the beginning of any project construction activity that could affect the previously unsurveyed portions of the project site, qualified archaeologists shall survey all portions of the site that were not examined during intensive surveys for the current effort, including unsurveyed portions of the pipeline alignment for the recycled- water distribution system(0.96 mile in the central portion of the project area between Swanson Road and West Center Street north of Yosemite Avenue, and 0.54 mile in the southwestern portion of the project area south of Woodward Avenue),pumping station sites,the side-bank outfall site, and approximately 3.35 miles of the pipeline alignment for the proposed wastewater collection system(2.05 miles in the southwestern portion of the project site near the intersection of Peach Avenue and Airport Way, and approximately 1.3 miles in the center of the western portion of the project area between Yosemite and Louise Avenues, and west of Airport Way). The survey shall be conducted during a time when the affected sites can be plowed and disked, so the natural ground surface can be examined for traces of prehistoric and/or historic-era cultural resources. Surveys of these areas are not necessary if it is determined that the areas would not be affected by project construction-related activity, including equipment staging or material stockpiling. Before the onset of project-related ground-disturbing activities (e.g., land clearing), all construction personnel shall be alerted to the possibility of uncovering buried cultural resources and shall be educated by a qualified archaeologist as to identification of archaeological artifacts.If an inadvertent discovery of cultural materials(e.g., unusual amounts of shell, animal bone,bottle glass, ceramics, structureibuilding remains)is made during project- related construction activities, ground disturbances in the area of the find shall be halted and a qualified professional archaeologist shall be notified regarding the discovery. The archaeologist shall determine whether the resource is potentially significant as per the CRHR and shall develop appropriate mitigation. Mitigation Measure 4.12-3: Discovery of Human Remains during Construction. California law recognizes the need to protect interred human remains,particularly Native American burials and associated items of patrimony, from vandalism and inadvertent destruction. The procedures for the treatment of discovered human remains are contained in Sections 7050.5 and 7052 of the California Health and Safety Code and PRC Section 5097.
