Take a look at homes near San Quentin. This is a prison that harbors some of the most hardened criminals in California. Low crime rate and high home values. Not a lot to be concerned about IMNSHO.
It is a good thing that you have the disclosures before you finalize your deal! Nevertheless we have these things and others anywhere. In so. Orange County we have landfill, methane gas, and abandoned army sites that are still in need of environmental clean up. It is very challenging to find a house in a pure environment and far from all environmental and social hazards.
If you feel that your life will be impacted in a negative way living in such condition you should express your concern and walk away. What you get as disclosure will be passed on to the future buyer. In a slow market where buyers have so many to select from these issues will be more noticeable. In a hot market people will not pay close attention to these issues.
