Local record guide
Local profile
Windsor, a place of 26,344 people, is in Sonoma County, whose county seat is Santa Rosa.

Windsor's own offices are in the cards above, and our Sonoma County page lists each county office.
Abandoned mine records
Where the workings are, and the office that holds the mine maps.
From the old mine records
The old survey maps record 1 hole inside the city or town limits, 0 of them shafts or tunnels.
A point in either file is a location, not a property line: the sheet shows the opening on the surface, not the rooms under it. The record that shows what runs under a parcel is the mine map. The OSMRE National Mine Map Repository holds scanned underground mine maps and answers requests for a named mine or an area.
California abandoned mine maps ranks every county and town in the state by the workings recorded inside it, names the office that holds the mine maps, and says what to do if the ground moves.
Disclaimer: The mine information here is for general information only. Old mine records can be incomplete, outdated or wrong, and finding nothing here does not mean there is nothing there. Check with the mine map office named here before you rely on it, and have a qualified engineer look at any ground you are worried about. PublicRecordCenter.com assumes no responsibility or liability for any errors, omissions, or consequences arising from the use of this information.
