SMB ENVIRONMENTAL June 8, 2015 Rita Di Candia City of Pleasanton 200 Old Bernal Avenue Pleasanton, CA 94566 Subject: Proposal—Archaeological Monitoring Services for the City of Pleasanton's Recycled Water Project Dear Ms. Di Candia: SMB Environmental, Inc. (SMB) is pleased to provide this proposal to provide archeological construction monitoring for the City of Pleasanton's Recycled Water Project. What follows is a summary of the Project Description, the proposed scope of work, and the estimated budget for completion. PROJECT DESCRIPTION SUMMARY In summary, the City proposes to install pipelines for the distribution of recycled water throughout the City of Pleasanton. The proposed construction would basically include approximately 22-miles (115,200 linear feet) of pipeline ranging inform 6-inches to 18-inches in diameter and would be placed primarily within existing paved roadways throughout the City. In addition, the Proposed Action would also include 3.2 miles (16,500 linear feet) of existing pipeline that will be repurposed from abandoned or existing potable pipelines. The construction techniques would be primarily using open-cut trenches approximately 3-feet wide and 6-feet deep. All creek and/or drainage crossings would be constructed using trenchless construction techniques. As part of the Section 106 cultural resources investigation process, a records search was conducted through the Northwest Information Center (NWIC) at Sonoma State University. On May 5, 2014, NWIC issued NWIC File #: 13-1672, which identified five known cultural resources within the Proposed Action alignment, including two prehistoric sites, two historic canals, and a historic railroad alignment. In addition, 41 prior cultural resources studies have covered approximately 75% of the Proposed Action alignment. Of particular concern to the Office of Historic Preservation (OHP) is the City's Proposed Project's ability to adversely affect CA-ALA-46 and CA-ALA-413. As a result, the city needs to have a archaeological monitor, monitor the two sites (i.e. CA-ALA-46 and CA-ALA-413) during construction activities.
