The Playa Vista development, located near Marina Del Rey, California, has drawn political opposition over land-use issues and building safety concerns dating back to the 1990’s, which continued through the project’s inception in 2001. At the heart of the public safety concern was naturally occurring methane gas, which is known to be explosive if allowed to accumulate in confined spaces. Of secondary concern was the potential of VOCs in the soil and groundwater left over from the site’s former use as an aeronautics manufacturing facility and runway. Without engineered safety measures the impacted soil could present a danger to the residents and workers of the new Playa Vista community.
In order to address these public safety and health issues, the City of Los Angeles Department of Building Safety (LADBS) enhanced an already-strict methane ordinance and mandated that all structures at Playa Vista be equipped with methane gas and VOC mitigation systems. Integral to the mitigation systems has been the use of LIQUID BOOT®, a spray-applied membrane that forms a gas-tight vapor barrier. Used along with sub-slab venting and monitoring systems, LIQUID BOOT serves to protect the buildings and their occupants at Playa Vista from methane gas and VOC vapor intrusion.
