Abandoned mine records
Where the workings are, and the office that holds the mine maps.
From the old mine records
The mine records hold 194 named mine sites inside the county, 151 of them worked out or abandoned; the old survey maps add 113 holes drawn inside the county, 17 of them shafts or tunnels. The minerals the records name are Stone; Mercury; construction sand and gravel.
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.
Rows taken off the old survey maps open the USGS record of what sits at that spot, because no single feature on those maps has a page of its own. Rows from the mine records open their own USGS page.
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 Old mine records can be incomplete, outdated or wrong, and finding nothing here does not mean there is nothing there.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.
The Contra Costa Health vital-record office handles births and deaths in the current and previous calendar year. Older events go to the Clerk-Recorder. This distinction matters before choosing a counter or mailing an application. The Clerk birth-certificate table lists $38 for a certified copy in 2026. The same Health instructions lists $30 for a death certificate, while the Clerk marriage table lists $23 for a marriage copy. These charges concern copies of completed records, not a new marriage-license application.
The Superior Court file-order notice places noncriminal records at Wakefield Taylor Courthouse, 725 Court Street, Room 103, effective January 12, 2026. It also says in-person records requests remain unavailable until further notice. The address change does not establish a walk-in copy service. Those instructions distinguish noncriminal requests from criminal files and report that online minutes, case documents and orders are unavailable. Use the stated request method for the file type; a search result alone is not the document.
The Clerk-Recorder holds land instruments. The Assessor maintains assessment information, and the Registrar of Voters handles election records. Supply a recording reference for a deed request or a parcel identifier for an assessment question.
For a court visit, use the Pittsburg courthouse location page to distinguish building hours from clerk-window and telephone hours. The California record guide gives statewide routes beyond the county offices.

By mail with form VS 111 to California Department of Public Health, Vital Records, MS 5103, P.O.

Its service description covers the current and previous calendar year. Request older local certificates from the Clerk-Recorder.
The dated Clerk fee table lists $38 per certified copy. Optional payment or delivery charges are separate.
No. The marriage-copy schedule lists $23 for a certified copy of an existing record; licensing is a separate service.
The records notice says in-person requests are unavailable until further notice. Follow its current ordering instructions even though a new office address is listed.
The file-order page distinguishes those requests. Select the criminal-record route instead of submitting a criminal request as a noncriminal order.
The Court notice reports unavailable online minutes, documents and orders. Obtain the needed document through the clerk rather than treating a case listing as the signed order.
Use the Assessor for assessment information. The Clerk-Recorder is the separate custodian for recorded deeds and liens.
The courthouse instructions state 4 p.m. for filing windows and 3 p.m. for answered telephone calls. Building access has a different closing time.
