I-5/Valley View Highway Widening Project; Buena Park, La Mirada, Cerritos and Santa Fe Springs, CA

Summit provided both in charge environmental consulting and contracting services for the 200 million dollar Valley View interchange construction project for the California Department of Transportation (Caltrans). The construction job consisted of the widening of both the Valley View overcrossing and the I-5 freeway. As part of the construction, thirteen industrial properties and several government owned parcels previously determined to be contaminated required to be excavated, stockpiled, sampled, characterized and transported for proper disposal.

Summits scope of services included the completion of the following plans: Site-Specific Health and Safety Plan, Sampling and Analysis Plan, Excavation Plan, Transportation Plan, and a Stockpile Management Plan. The field services provided included the stockpile sampling and analytical testing for 1200 stockpiles and 6000 samples and the characterization transportation and disposal for more than 42,000 tons of contaminated material. In addition, Summit performed dewatering, sampling, and liquid disposal for more than 400,000 gallons of contaminated liquid. Summit also performed all oversight health and safety compliance and summary report preparation.

Summit received high marks for safety, communication, efficiency and overall performance.

Placentia Avenue

Placentia Avenue Grade Separation Project – Placentia, CA

Orange County Transit Authority (OCTA):
Placentia Avenue Grade Separation Project – Placentia, CA

Summit provided both in charge environmental consulting and contracting services as part of the Burlington Northern Santa Fe (BNSF) Placentia Avenue Grade Separation project.  This was the first of seven-grade separation projects along the BNSF/Orangethorpe Corridor being constructed in the Orange County Bridges program. The construction project consisted of lowering the Placentia Avenue roadway under the BNSF tracks to provide a grade-separated crossing. Construction of bypass tracks and a temporary detour road were necessary to construct the Project. Summit’s scope of services included work reviewing existing environmental reports for the site, as well as the completion of the following plans; Site-Specific Health and Safety Plan, Sample and Analysis Plan, and Soil Excavation Management Plan.  The field services included soil sample collection along 2,300 feet of track, soil analysis and characterization, and stockpile sampling. Statistical analysis and perceived options for hazardous material disposal and reuse, in addition to management of the transportation and disposal of over 130,000 tons of non-hazardous and California Hazardous soil, were completed by Summit.

Santa Clarita

Interstate 5 – Santa Clarita, California

Caltrans:
Interstate 5 – Santa Clarita, California

Summit performed an aerial deposited lead investigation along Interstate 5, in Santa Clarita, California as part of a highway construction project for the State. The objective of the investigation was to re-evaluate soil that had previously been determined to contain aerially deposited lead due to the historical use of leaded fuels by freeway traffic. The purpose of this reclassification was to increase the amount of soil that could be classified for reuse on site.

The data collected from the limited soil investigation and laboratory testing was used to profile and for both export and on-site reuse. Soil samples collected from 18,000 cubic yards of stockpiled soil located at the site were analyzed for total lead, soluble lead, and pH. As a result of Summit’s analysis, all of the stockpiled material previously classified as Z-2 material was reclassified as Y-1 or unrestricted reuse.

Summit’s conclusions for soil reuse on-site were based on guidelines set forth by the DTSC, Lead Variance issued to Caltrans on June 30, 2009 (DTSC Variance) Laboratory analytical results for lead were compared to the guidelines of the DTSC Variance for potential reuse of the soil as fill within the Caltrans right-of-way.

Santa Fe Springs

Interstate 5, Santa Fe Springs, and Norwalk, California

Caltrans:
Interstate 5, Santa Fe Springs, and Norwalk, California

Summit provided consulting services as part of the construction of the Interstate 5/Carmenita Road Interchange project. The construction included the removal of the existing two-lane grade separation over-crossing at Carmenita Road, realignment of existing frontage roads, and construction of a tight diamond interchange with a new Carmenita Road over-crossing grade separation structure over Interstate 5 and the Union Pacific Railroad crossing. New right-of-way acquisitions of residential and industrial properties, both full and partial-takes, as well as permanent and temporary construction/grading easements, were needed to accommodate the project construction.

Services included preparation of a health and safety plan, excavation and transportation plan, lead compliance plan, sampling, and analysis plan, and transportation and disposal plan outlining the requirements for the handling of contaminated material. Fieldwork included geotechnical drilling of seventy (70) soil borings to approximately sixty (60) feet below ground surface to determine the location and thickness of the impermeable layer above the Artesia Aquifer and oversight, monitoring, and soil sample collection from over twenty (20) excavations and soil stockpiles. In addition to preparing monthly reports, Summit conducted statistical analysis for the evaluation and recommendations for the perceived options for management of contaminated soil (disposal or reuse on site).
