<br />outside of formal cemeteries?
<br />a) Historic and archaeological resources were evaluated in the San Leandro General Plan Update EIR (November 2001). A
<br />review of historical maps indicate that the property, while currently developed with a commercial office use, was
<br />previously part of the Singer Friden Factory property, but that previous use has since been demolished. Prior to that, the
<br />site was previously occupied by orchard trees until the early 1950's when it was used by Singer - Friden for parking and /or
<br />storage. The existing two -story building was constructed for research and development by Singer - Friden in
<br />approximately 1965. Although the site was part of the Singer - Friden facility, the project site was never used as part of
<br />the manufacturing process. No recognized environmental conditions (RECs) were identified during the Phase I ESA
<br />(Secor, 2007). A review of the 1950 and 1957 Sanborn maps identified the site as having been used for automobile
<br />parking adjacent to the Friden Calculating Machine Company, which was previously located northwest of the site. A gas
<br />and oil (service station) was previously located east of the project site. There are no other remnants of the site's previous
<br />Ilse existing on - parcel. Therefore structures a the project site and lro impact.- Wbuildings ol�
<br />resources that could have historic status.
<br />b - d) Based on an evaluation of the environmental setting and features associated with known sites, Native American cultural
<br />resources in this part of Alameda County are found in many areas adjacent to water resources, like the bayshore or
<br />intermittent and perennial watercourses. The proposed project area is on a broad alluvial plain that is marginal to the
<br />bayshore. For this reason it is unlikely that unrecorded Native American cultural resources exist on the project site.
<br />Although the project site does not contain recorded Native American or historic- period archeological resources, there
<br />remains a low possibility of encountering Native American and cultural archaeological or human remains during site
<br />disturbance. However, construction -phase demolition and re- building activities could result in ground disturbance that
<br />would cause a substantial, adverse change in the significance of an unknown archeological resource.
<br />Mitigation Measure #10: The applicant shall cease any grading or construction activities and shall consult with
<br />appropriate representatives of the Native American Heritage Commission if human remains are discovered, in
<br />accordance with State Law and Section 7050.5 of the Health and Safety Code, Section 15064.5 (e) of the State
<br />CEQA Guidelines and Section 5097.98 of the Public Resources Code.
<br />Implementation of Mitigation Measure #10 reduces potential impacts to a less than significant level.
<br />a. Expose people or structures to potential substantial
<br />adverse effects, including the risk of loss, injury, or
<br />death involving:
<br />i) Rupture of a known earthquake fault, as delineated on

<br />5, 6, 7, 8
<br />the most recent Alquist- Priolo Earthquake Fault
<br />Zoning Map issued by the State Geologist for the area
<br />or based on other substantial evidence of a known
<br />fault?
<br />ii) Strong seismic ground shaking?

<br />C. Be located on a geologic unit or soil that is unstable, or
<br />X
<br />5, 6, 7, 8
<br />that would become unstable as a result of the project,
<br />and potentially result in on- or off-site landslide, lateral
<br />spreading, subsidence, liquefaction or collapse?
<br />d. Be located on expansive soil, as defined in Table

<br />18. 1.13 ofUBC (1994), creating substantial risks of life
<br />or property?
