Seventy-five years ago Los Angeles was the biggest producer of oil in the world. A by-product of drilling for oil is methane gas. 70% of Los Angeles has methane gas. There is less methane gas in Playa Vista than in other Los Angeles areas including tested Marina del Rey and Venice who do not have a methane gas detection system. Playa Vista's state-of-the-art methane gas detectors are studied all over the world and these systems consistently measure zero.
Playa Vista residents speak at at City Hall on behalf of their community regarding the methane issue. The Fire Department and Building and Safety department heads, etc. continually vote in favor of Playa Vista and one was quoted as saying, "Playa Vista is safe. If I had the money I'd move my family into the community."
Yet 11th District City Council member, Bill Rosendal and Patricia McPherson, former actress in the 80s TV show, Knight Rider, continually sue the community. They work with a group called Ballona Wetlands Trust who are made up of attorneys and others who receive grants to sue Playa Vista, however, they never won any of their multiple lawsuits, proving there's no science behind these accusers.
NBC report negatively about the environmental dangers of Playa Vista. However, the dewatering systems of Playa Vista have been tested by three independent civil engineering companies and proven to have no environmental impact.
As you can see, it refers the buyer to the particular builder (or
Subassociation, with respect to ongoing maintenance) for specificity as to the methane mitigation system for a particular project.
The CLA Report about methane mitigation systems for Phase 1 was an attachment to the Village DEIR, and it is on the web.
To find it, you go to cityplanning.lacity.org; click on Draft EIRs;
scroll to and click on the Village at Playa Vista; click on the Draft
Environmental Impact Report for the Village (from 2003) -- NOT the RS-DEIR; click on the Technical Appendices to the Draft Environmental Impact Report for the Village; then click on Technical Appendix J; then click on the 2001 CLA Report at Item J-6.
This won't give the specifics as to the mitigation system for a
particular project, but it will discuss methane in Phase 1, and an
overview of the mitigation systems. It includes the methane mitigation matrix that LADBS uses for Phase 1 -- but the specific mitigation system for a particular building needs to be described by the builder (or the Subassociation) for that building.
The specifics of the mitigation system in a particular project are
really the purview of the builder and LADBS, not Playa Capital.
