Monterey Cypress failure data

Was curious,
is there a place that has statistics of the more common methods of failure related to each species. (someone was working on a data base years ago)
The hazzard tree eval guide says monterey cypress rarely fail as a whole tree, and i usually see limb and upper trunk failures.
But i need some data to prove to a landowning corporation that their tennants are at risk.
The thing that sucks is i'm the 3rd arborist to see these trees, Heck an asca arborist/ forrester already saw the trees, i think the corp is shopping for oppinions, only this time a copy of my report has to go to the state housing authority to answer a complaint.
I worked up each tree using the standard hazzard eval form, performed a partial root crown excavation, drilled a few damaged looking roots, drilled some seams in the trunk, and have sounded the trunk using a rubber mallet.
I just want to bolster my info with some statistics showing their failure rate as a species.
Any serious comments would help, thanks tree housers

The national tree failure database may have usable data. Paul Reese and Norm Hol are a couple of the higher ups from the western side of the country within that organization. as far as I know.

You can start here.

Google is your friend.

yeah i got the ca tree failure info and its mainly on monterey pine but did have some info on mont cyp

thanks paul and mr sir

Hey
the people at the failure group e mailed me some great stats, most excellent group
they deserve some thanks
so THANKS

They put on a great conference on tree failures at Filoli in Woodside every year. Awesome speakers from all over the country.

They have a meeting up here every third year. I have been twice, pretty cool stuff and yeah, good speakers, I think the last one I went to Dr Brian Kane spoke, the one before that I think it was Paul Reis. I got to see the ground penetrating radar unit in action last time too, really cool bit of equipment.

Here's the venue for the conference.

Beautiful place started by one woman, It still thrives.
