Is the quarry near communication hill still active?

Asked by Curious buyer, San Jose, CA Wed Jul 4, 2012

I'm thinking of buying nearby, but I'm worried about the dangers of asbestos exposure. Communications hill contains naturally occurring asbestos rock. There's what looks like a cement quarry at the base of the hill (33 Hillsdale) and I'm worried if its active it could stir up dangerous dust.

I agree with Charles. The best resource is the County. As Charles, I too have represented clients for Communication Hill and I can walk there from where I live.…

Here's a link to point you to some resources.

Thank you, Curous buyer for your question.

The geologist for Santa Clara County is your best source of information with respect to that issue.

I have spoke with the County Geologist with respect to that very issue for a client who I represented on the purchase of a home in that area. The information from the county Geologist was very good.

I recommend that you get that information from the County Geologist rather than second hand from me or someone else.

If you are represented by a REALTOR I recommend that you ask your REALTOR to get that information for you.

If you are not represented by a REALTOR you may call me on my cell phone: (408)509-6218, and I will help you get that information.

Regarding the Geologist's report that evaluated the property prior to building the development on Communications Hill - I read the entire report online and know for a fact that there were errors on the report. How do I know this?: Because I lived on the property in one of the dwellings of the ranch that existed there for over 100 years - the ranch was demolished by the developer. I lived there from 1985 - 1993 and knew all that land like the back of my hand. In particular, the geologist featured a photograph on the report of an Indian Chert Station that he positioned in a completely different location than it actually was - I know this because I could tell where the photo was taken from what appeared in the background of the photo. He never pursued additional evidence of Indian presence which I'm certain was on that land. He did not identify 3 septic tanks on the land either. There were also many mine shafts all over the property where quicksilver was mined.

Hi Curious Buyer,

You have received some very good information from my fellow Realtors. I would also recommend that you call the county health department and maybe the state health department regarding the naturally occurring asbestos rock. I would also Google it to check for more info. A few years ago their was some press about this very issue in the El Dorado Hills above Sacramento and the health effects. Check out this article… Their should be lots of info for you so you can make an informed decision. Be sure you have all the facts before you decide what to do. If you have an agent already they should also be able to help you. I hope this was of some help to you.
