Project Experience

UST Removal at UCLA – Los Angeles, California
The Reynolds Group was contracted by a mechanical company that represented the UST owner, UC Regents, to remove three underground storage tanks at the University of California, Los Angeles. Under extraordinary physical constraints, using shoring, TRG and its own subcontractors helped UCLA remove three old UST’s in a highly trafficked, highly public area. The tight urban space constraints required the expert organizational and managerial skills to coordinate the team in a safe and efficient manner. The project was completed within the specific time frame and the UST removal resulted in regulatory closure at the site.

Removal of Contaminated Material – Upland, California
The Reynolds Group was hired by a Real Estate Property Management Company who needed assistance in removal approximately two yards of contaminated material and concrete from a former agricultural used property. The field work was completed on time and on budget.

Permit Compliance – Orange, California
The Reynolds Group was retained by a manufacturing company in Orange, California to assist in the compliance of permits with various agencies in Orange County. The Reynolds Group confirmed all monitoring and sampling were in compliance with agency requirements along with permit renewals. The Reynolds Group successfully managed the company to get back into compliance with all agencies.

Habitat Restoration at Local Pond – Silverado, California
The Reynolds Group completed a turnkey restoration project for the Orange County Department of Education (OCDE). The program gives children hands-on experiences about nature and fosters their enthusiasm for the environment at the pond. Over the course of five years, the pond was overtaken by invasive plant species. During the winter, heavy rains caused debris flows to fill in much of the pond leaving it susceptible to further rapid encroachment by invasive species.

Working with OCDE’s on-site managers and TRG’s own biological resource specialist, TRG was able to scope the habitat restoration project and provide a not-to-exceed price to clear the pond of the invasive plant species and unwanted sediment. The scope and price also included training the OCDE staff to take steps to prevent and limit the return of the pesky plants. The work included clearing menacing plants and using limited access heavy equipment to create erosion control on the slopes around the OCDE property. Catch basins were constructed to slow stormwater flows and capture sediment before they reached the pond.

Environmental Site Assessment at a former Automobile Service Station – Los Angeles, California
The Reynolds Group was retained by a Japanese widow who owned a former automotive service station in Los Angeles, California. The client had removed three underground storage tanks at the site ten years ago and had not received an official closure letter. The Los Angeles Fire Department requested an environmental site assessment to be performed at the site to confirm whether or not any contamination was left from the removal of the USTs. The Reynolds Group came in and assisted in keeping the client in compliance with the LAFD and performed the assessment. The soils assessment resulted in non-detect in gasoline and its constituents. The Los Angeles Fire Department issued a no further action letter on May 28, 2013.
