Boreal Woodward Freestyle Training Center – Soda Springs, CA

Holdrege & Kull provided geotechnical engineering, environmental engineering, Storm Water Pollution Prevention Plan (SWPPP) development and monitoring, and earthwork observation and special inspection services for the Boreal Mountain Resort Woodward Tahoe Freestyle Training Center. The project involved construction of a 33,000 s.f., pre-fabricated, clear-span, metal structure with slab-on-grade floors. The building has two mezzanine levels and is 60 feet in height. Other project elements included a BMX park, skateboard park, and alpine coaster.

Existing loose fill was encountered within the proposed building envelope during H&K’s initial geotechnical engineering investigation. Some of the existing fill contained solid waste that was found to locally impact groundwater with petroleum hydrocarbons such as motor oil and diesel. H&K performed an additional environmental investigation to delineate the horizontal and lateral extent of existing fill and prepared a Removal Action Plan (RAW) that was approved by the Nevada County Environmental Health Department (NCEHD). H&K also provided environmental observations and soil and groundwater sampling during the removal of existing fill at the site, assisted with the offsite disposal of solid waste, and acted as liaison with NCEHD and the California Regional Water Quality Control Board, Central Valley Region.
