Downtown San Diego
Performed a Phase I ESA for a Class A office tower and parking structure in the Cortez Hill area of downtown San Diego. Identified historical dry cleaning operations, printing facilities, automotive repair and gasoline service stations on the property. Although a portion of the property had been excavated for the office tower, the parking garage with ground-floor retail were slab-on-grade, and constructed in the 1950s. Therefore, historical activities of concern onsite were identified as Recognized Environmental Conditions.

Palm Tree Farm, Carlsbad, California
Conducted a Phase I ESA for a palm tree farm slated for residential development. Previous reports identified organochlorine pesticides in soil, however the extent of impact was not defined. Conducted additional Phase II sampling. Identified a former UST during the Phase I process and conducted soil sampling to confirm no impacts were present.
Los Angeles Charter School
Conducted a Phase II environmental site assessment for a charter high school in the Koreatown area of Los Angeles to evaluate for potential contamination due to the presence of automotive repair facility at an adjoining property. Additionally, methane sampling was conducted due to the school’s location within a methane zone. Soil and soil vapor sampling were conducted.
Oversaw Phase I and Phase II ESAs in conformance with the requirements of LAUSD. Soil sampling was conducted to evaluate for the presence of lead resulting from lead-based paint used on the exterior of buildings; arsenic historically used for weed control; and organochlorine pesticides used as termiticides. Completed the California Department of Education (CDE) checklist.
Oversaw Phase I and Phase II ESAs and CDE checklist completion; managed soil excavation and disposal.
Los Angeles, California
Prepared a Phase I ESA for a 23-story, 393-room hotel in downtown Los Angeles. The site was originally part of a large redevelopment project which included an additional hotel, retail, and sports/entertainment venue. Extensive environmental assessment was conducted during redevelopment which required review during the Phase I ESA process. Identified nearby release cases and conducted extensive LARWQCB review of nearby sites to confirm adequate assessment and remediation had occurred and that no vapor intrusion concerns existed for the subject property.
San Diego, California
Provided oversight during reconstruction activities at a hotel on the San Diego Harbor. The site had a closed LUST case which required additional sampling in the case of redevelopment. Participated in developing and implementing a site mitigation plan for sampling and management of contaminated soil. During the course of redevelopment burn ash was encountered, as well as impacts from a leaking elevator. Impacted soil was removed from the site under manifest. Assisted with preparation of the closure report.
Rancho Santa Fe, California
Prepared a Phase I ESA for an historic hotel and associated residential rental properties.
Light rail project, San Diego
Part of a team evaluating potential impacts from nearby release sites along a rail corridor. Reviewed a previous Phase I ESA report to determine if adjacent release sites would have migrated onto the railroad property. Evaluated soil for the presence aerially-deposited lead, as well as arsenic historically applied for weed control, prior to start of construction activities.
Transit Corridor Environmental Study, Los Angeles
Part of a team developing a hazardous materials impact analysis. Developed a methane evaluation and mitigation plan for tunnel sections crossing methane zones in the City of Los Angeles.
San Diego, California
Part of a team conducting a Phase I ESA on a large property occupied by an entertainment and sports venue. The property was historically occupied by a World War II-era housing complex and is surrounded by multiple release sites. Conducted the site visit and evaluated potential historical and offsite environmental concerns. Identified numerous RECs and assisted with developing Phase II scope of work.
Huntington Beach, California
Conducted Phase I and Phase II ESAs for a property in Huntington Beach slated for residential development.
