Agenda 12/12/2023 Item #16F 9 (Change Order to conduct an Environmental Site Assessment)12/12/2023
EXECUTIVE SUMMARY
Recommendation to approve Change Order No. 6, for $485,259 under Agreement No. 19-7650, Golden Gate
Golf Course Redevelopment Planning and Engineering, to conduct an Environmental Site Assessment at
Golden Gate Golf Course and provide recommendations for rehabilitation, and authorize the Chairman to
sign the attached Change Order. (Project No. 80412)
OBJECTIVE: To conduct an extensive environmental site assessment at the Golden Gate Golf Course and
provide recommendations for rehabilitation completion.
CONSIDERATIONS: On December 12, 2019 (Agenda Item 16.F.11), the Board awarded Request for
Professional Services No. 19-7650, the "Golden Gate Golf Course Redevelopment Planning and Engineering"
project to Davidson Engineering, Inc. (“Davidson”).
The scope of the environmental evaluation of the Golden Gate Golf Course will include all areas of the property
except the Residential Tract and Commercial Tract. The soil and groundwater quality assessments are intended to
confirm any presence of contaminated soil and groundwater on the site. Those assessments will entail three separate
rounds of testing and analysis, incorporating a total of 880 soil samples from 450 bores and 30 groundwater
monitoring wells.
The soil testing will focus on exploring the presence of:
• 6020/6010/7470, covering 8 RCRA metals (namely, arsenic, barium, cadmium, chromium, lead, mercury,
selenium, and silver)
• 8081 for Organochlorine Pesticides (OCPs)
• 8141 for Organophosphorus Pesticides (OPPs)
• 8318 for Carbamates Pesticides (CPs)
• 8270 for Triazine Pesticides (TPs)
• 8151 for Chlorinated Herbicides (CHs)
Groundwater testing, on the other hand, will focus on exploring the presence of:
• 6020/6010/7470, comprising the same 8 RCRA metals
• 8081 for Organochlorine Pesticides (OCPs)
Davidson requested a proposal from Universal Engineering Sciences (“UES”) to conduct the environmental site
assessment at the Golden Gate Golf Course. UES is a well-established engineering and consulting firm boasting
over 3,600 professionals in 85 locations throughout the United States.
On August 10, 2023, UES submitted its proposal to Davidson, which outlines the scope and cost to conduct the in-
depth environmental site assessment for the Golden Gate Golf Course and focuses on offering recommendations for
the rehabilitation completion process. The scope of services was developed based on the existing environmental
documentation for the property and includes Site Assessment Reports, Interim Source Removal Plans, Soil
Management Plans, Engineering and Institutional Controls, and the development of Alternative Soil Cleanup Target
Levels. Staff is recommending that the Board approve Change Order No. 6 in the amount of $485,259 so that the
environmental site assessment can proceed.
FISCAL IMPACT: Funding in the amount of $485,259 for conducting a site assessment of Golden Gate Golf is
available in the County-wide Capital Projects Fund (3001) Golden Gate Golf Course Project (80412).
LEGAL CONSIDERATIONS: This item is approved as to form and legality and requires majority vote for
Board approval. -SRT
GROWTH MANAGEMENT IMPACT: This action has no impact on the Growth Management Plan.
