Ms.Di Candia Page 2 June 8,2015 SCOPE OF WORK Detailed below are the specific tasks, SMB proposes to undertake to provide archaeological monitoring for CA-ALA-46 and CA-ALA-413 during construction of the City's Recycled Water Project(Project/Proposed Project). Task 1 —Archeological Monitoring SMB will provide archaeological monitoring at the two locations within the project area (i.e. CA-ALA-46 and CA-ALA-4l3). The Archaeological Monitor will, at minimum, have a Bachelor of Arts or a Masters in Archaeology, at least three years of field experience in California Archaeology, and will meet the Secretary of the Interior's Standards for Prehistoric Archaeology. • A qualified archaeologist will monitor pipeline trenching during construction as it passes near the known area of CA-ALA-46 and a 300-foot buffer on either side. Since the site as recorded extends for approximately 350-feet parallel to West Las Positas Boulevard, the total monitoring distance will be 850 linear feet. The budget estimate below assumes that pipeline installation will proceed at a rate of 500-feet per day, requiring two days of monitoring. The monitor will complete a daily monitoring log discussing the day's activities and findings. • A qualified archaeologist will monitor pipeline trenching during construction as it passes near the known area of CA-ALA-4l3 and a 300-foot buffer on either side.

The monitor will complete a daily monitoring log discussing the day's activities and findings. In the event that any prehistoric and/or historic deposits are encountered during such monitoring, it will be the responsibility of the archaeological monitor to stop work within 100-feet of the discovery until the resource can be evaluated according to the measures outlined in the Inadvertent Discovery Plan that was prepared in consultation with the State Water Resources Control Board(State Board) and OHP. If an historic or prehistoric resource is determined eligible for either the National Register or the California Register, a research plan for mitigation of effect will be submitted to the City of Pleasanton for approval before work is allowed to recommence in areas of archaeological sensitivity as defined by the project archaeologist. Mitigation may take the form of data retrieval through additional hand excavation inside areas of impact, coupled with recording and/or removal of significant cultural materials and information for future analysis and reporting purposes. In the event that human remains are found, the archaeologist will contact the County Coroner and, if determined to be Native American, the California Native American Heritage Commission (NAHC) will be notified to identify the Most Likely Descendent (MLD), in accordance with state and federal law. The MLD will advise the City of 225 Nunzia Court Roseville, CA 95661 www.smbenviromental.com 916-517-2189
