Los Angeles County carries one of the heavier federal records we track — 57,418 documented sites, most of them brownfields. That's a record of the area's history, not a verdict on any one yard: proximity to a documented site is information, not a diagnosis. Before food beds go in, a professional soil test tells you exactly what you're working with — and raised beds with clean imported soil grow well almost anywhere in the meantime.
