While I worked for the County of San Diego, my office received a panic  
telephone call that a bulldozer "vanished" while scraping up an asphalt parking  
lot. It seems the asphalt covered an early 20th century brick factory with about 
 20 large circular kilns and dozens of brick-lined tunnels that redirected 
heat  from one kiln to the other. The tunnels were crammed with all sorts of 
holly  clay tile and other stock they forgot to clean out over the decades. After 
a  series of frantic telephone calls, County Mental Health (who were building 
a new  center at the location) let a contract to RECON, a local contracting 
company and  they produced a nice report on the testing, mapping and sample 
recovery. Copies  of the report can be obtained at the South Coastal Information 
Center, San Diego  State University. Susan Hector authored the report. We also 
had Karl Gurcke  flown out to render his opinion on the complex. Ironically, 
the kilns were built  from bricks shipped down from the Los Angeles Brick 
Company.
