JEFFREY ADAMS, PHD, PE Geographic Information System (GIS) digital interactive platform that provides additional data beyond typical environmental information and is scalable for future project plans. The South Lathrop Commerce Center—Tracy, CA Lead Environmental Principal. Jeff provided technical leadership and review for a Phase I ESA for the approximately 245-acre master-planned industrial development. The 4.2-million-square- foot development includes nine tilt-up concrete buildings, ranging in size from 282,000 square feet to over 1,000,000 square feet. Additional improvements for the logistics center include detention and retention basins, paved streets, parking, and drive lanes, a stormwater pump station and outfall, and a sewer lift station. Site development activities include grading operations, primarily consisting of minor cuts and fills, for individual pads and roadways, underground utility installation, pump station and outfall structure construction, flexible and rigid pavement construction, and vertical construction. Crown Chevrolet Property—Dublin, CA Project Manager. Jeff provided comprehensive environmental consultation services for the project. Working on behalf of the purchaser, Jeff collaborated with a multi-firm consulting team to characterize and mitigate environmental impacts resulting from previous on-site automotive maintenance activities and off-site businesses. Jeff designed and managed a site characterization program that definitively demonstrated that groundwater and soil gas impacts at the site were the result of off-site releases. He peer reviewed the design and implementation of a permeable reactive barrier(PRB), which serves to remediate an encroaching groundwater plume, as well as vapor intrusion mitigation systems for the site. He also completed a Phase I ESA for a remnant parcel subsequently developed for housing for veterans. The site consists of a multi-story commercial and residential apartment/condominium "transit village" complex. 3512 Clayton Road—Concord, CA Lead Environmental Principal. Jeff provided technical leadership and review for a Brownfields redevelopment project in Concord. Following the Phase I and Phase 11 ESAs that identified soil and soil gas impacts, he assisted in the development of a remediation program that included a comprehensive pre-characterization program, accurately delineating soil impacts from past light- industrial uses and soil gas impacts from off-site businesses, allowing for accelerated field implementation. Following active soil remediation and post-remediation soil gas sampling, Jeff and the ENGEO team performed a vapor intrusion risk assessment that confirmed the site did not require long-term vapor mitigation systems. The site was granted case closure from the oversight regulatory agency within an accelerated review and approval timeframe. The project consists of a high-density residential development. Blacow Road Project—Fremont, CA Environmental Principal. Jeff has provided technical assistance for project remediation activities and prepared a Phase I ESA for site. The site is an active, open remediation site under the regulatory oversight of the San Francisco Bay Regional Water Quality Control Board (RWQCB). Impacts resulted from a variety of on-site and off-site commercial and industrial land uses dating back over 50 years. ENGEO has performed numerous characterization, remediation design, and monitoring services for the Site. Remediation activities are underway at the site to address groundwater and soil gas impacts from volatile organic compounds (VOCs)and petroleum hydrocarbons. The remediation approach consists of several remedial and mitigative technologies, including soil vapor extraction (SVE), in-situ enhanced bioremediation, and post-remediation vapor intrusion mitigation systems to be installed in future residential structures. The project consists of a residential development. GEO
