3.0 ENVIRONMENTAL CHECKLIST could be affected by project construction, if present. The potential for significant historic - period archaeological resources within the project area is high due to the numerous residences that once stood there. These residences are in an area of the City that is included in the original town plat (Higley 1855). The first residence appears on maps as early as 1907, with a total of seven buildings and six ancillary structures mapped within the project area by 1928. These residences are associated with the early settlement and agricultural periods of San Leandro's history which includes the timeframe when the city's population grew from 3,500 in 1911, to 5,000 in 1917, to 12,000 in 1928, and to 25,000 in 1950 (Sanborn Map Company 1911, 1917, 1928a, 1928b), and just before the City underwent a dramatic shift from being an agricultural community to becoming an industrial city. Historic -period archaeological deposits within the project area have the potential to contribute to local and regional research questions related to early settlement in the City and population growth during the shift away from agriculture and toward industry. Because of the site's elevated historic -period archaeological sensitivity, construction impacts on archaeological resources would be potentially significant and the City would require mitigation measures MM CUL-1 and MM CUL-2 to reduce potential impacts to a less than significant level. c) Less Than Significant Impact with Mitigation Incorporated. No paleontological resources were observed on the project site. In the event that paleontological resources are observed during project construction -related activities, standard, late -discovery mitigation measures are required. Mitigation measure MM CUL-2 would reduce potential impacts to a less than significant level. d) Less Than Significant Impact with Mitigation Incorporated. While human remains were not identified on the project site, in the event of discovery, the project would comply with California Health and Safety Code Section 7050.5. In the event that human remains are observed during project construction -related activities, mitigation measure MM CUL-3 is required to reduce potential impacts to a less than significant level. Mitigation Measures MM CUL-1 Archaeologist on -call during construction ground -disturbing activities. An archaeologist who meets the Secretary of the Interior's Professional Qualification Standards for Archaeology shall be contracted by the developer on an on -call basis to investigate if potential cultural resources are discovered during ground -disturbing activities. Timing/Implementation: During grading and excavation Enforcement/Monitoring: City of San Leandro Community Development Department MM CUL-2 Treatment of previously unidentified archaeological deposits and paleontological resources. If paleontological resources or prehistoric or historical archaeological deposits are discovered during construction, all work within 25 feet of the discovery shall be redirected and an archaeologist shall assess the situation, consult with a paleontologist and agencies as appropriate, and make recommendations regarding the treatment of the discovery. Impacts to archaeological deposits should be avoided by the project, but if such impacts cannot be avoided, the deposits should be evaluated for their eligibility for the California Register. If the deposit is not California Register 1388 Bancroft Avenue Project Initial Study/Mitigated Negative Declaration City of San Leandro November 2018 3.0-28
