When working with buyers I always suggest these two things;
go to Meganslist to see if there are registered sex offenders in the neighborhood and call the local polish dept to see what if any incidences have occured in a designated neighborhood.
Sometimes the police will give you little tidbits of additional info about a troubling area.
Good luck to you,
This should give you a visual idea.
However, compare Orinda's rate to national statistics
This comparison puts Orinda in an extremely better light.
Hope this helps
