6.1.B. - Page 1 REPORT To the Honorable Mayor and City Council From the City Manager January 22, 2018 SUBJECT Award of Contracts for Initial Groundwater Remediation Activities at Sequoia Station Shopping Center RECOMMENDATION By motion, approve and authorize the City Manager to: 1. Execute a Professional Services Agreement with Groundwater & Environmental Services, Inc. in the amount of $153,650 for management and coordination of quarterly groundwater monitoring events and initial remediation activities; and 2. Execute Amendment No. 1 to the Professional Services Agreement with Cascade Drilling, L.P. amending the scope and increasing by $18,641 the fees of the original agreement dated November 3, 2016 to perform subsurface drilling and initial groundwater remediation at the site, for a total not to exceed contract price of $75,257 BACKGROUND During development of the Sequoia Station Shopping Center in the mid-1990s, soil and groundwater investigations identified the presence of chlorinated solvents in the groundwater beneath the property. Since July 2014, the Public Works Services Department (PWS) has worked with the San Francisco Bay Regional Water Quality Control Board (RWQCB) to monitor and resolve the groundwater contamination. PWS engaged Groundwater & Environmental Services, Inc. (GES) to assist the Department with meeting the RWQCB's cleanup requirements. GES was instrumental in quickly organizing and meeting RWQCB mandates, as they had previously prepared a remediation study for the site in 2007. GES staff were able to leverage their historical first-hand knowledge of the site to guide the City's response. In October 2016, the RWQCB approved the City's site remedial action plan and PWS began preparations for a pilot project to test the efficacy of proposed groundwater remediation technologies. PWS contracted with GES for oversight and coordination of the pilot program, and released a request for proposals for a drilling contractor to perform the work. From the solicitation, PWS selected Cascade Drilling L.P. (Cascade) and entered into an agreement with the contractor in 2016. PWS concurrently started negotiations with the two property owners, Regency Centers and Safeway, to obtain site access. Due to difficulties negotiating with one of the property owners, the project was delayed for the past year.
