Closest trace ~2.9 mi · USGS Quaternary Faults
Mapped fault zones are mineralization pathways — hydrothermal fluids rise along faults and drop dissolved minerals as they cool. Many of the largest U.S. ore districts sit on mapped fault structures. Active faults can also signal geothermal potential and deep brines.

USGS classification: “industrial” is SIC-code-based and primarily reflects manufacturing. Data center cooling is not explicitly categorized and may not be isolated in this figure. Most recent USGS dataset: 2015.
Future iterations may add: cooling-method classification per facility, permitted-but-not-yet-built data centers via state environmental permit databases, and per-facility water-withdrawal volumes where operators voluntarily disclose.

Environmental records within ~10 mi
Most are routine regulatory registrations — not evidence of contamination
Notable: 5 federal Superfund (NPL) sites — the one category worth a closer look.
In assessment / redevelopment: 17 Brownfields sites — land being assessed or redeveloped.
Routine registrations: 100 registered facilities (toxic-release reporters and hazardous-waste handlers) — common in any developed area.
To confirm conditions for a specific parcel, a Phase I Environmental Site Assessment by a licensed environmental professional is the standard tool.

Mineral rights status
Unverified
Mineral-rights status defaults to 'unverified' — GeoLocity does not pull deed history. The state-default block below summarizes the state's framework for mineral-rights ownership when available. Confirm specific ownership with a licensed title professional.
Default rule in California
In California, a fee simple conveyance of real property is presumed to include both surface and mineral rights unless the grantor clearly reserves minerals in the deed. California Civil Code Section 1105 establishes that 'a fee simple title is presumed to be intended to pass by a grant of real property, unless it appears from the grant that a lesser estate was intended.' This means minerals pass with the surface by default — severance requires affirmative, express action by the grantor.
Severance likelihood: Low
Mineral estate severance is significantly less common in California than in traditional oil-producing states like Texas or Oklahoma. California's land tenure originated largely from Spanish and Mexican grants that rarely contained mineral reservations, establishing a legal tradition where minerals are presumed included with surface ownership. Severance, where it occurs, is concentrated in regions with known mineral or petroleum deposits (e.g., Kern County oil fields, Sierra Nevada gold country). Authoritative statewide percentage figures are not published by UC Cooperative Extension or comparable sources; the 'low' rating reflects scholarly and practitioner consensus relative to oil-state averages.
Framework: California Civil Code Section 1105 (fee simple presumption — verified via justia.com); California Civil Code Sections 883.200–883.270 (Termination of Dormant Mineral Rights — 20-year nonuse rule); California Public Resources Code Section 6401 (state reservation of minerals on public lands — verified via justia.com); California State Lands Commission administers tidelands and school land minerals.
Next step in California:
Mineral rights severances are recorded at the County Recorder's office in the county where the land is located. San Bernardino County Recorder's FAQ explicitly states that landowners should conduct a title search at the Recorder's office to determine if and when rights were severed (arc.sbcounty.gov). Los Angeles County Registrar-Recorder (lavote.gov) and Butte County (buttevotes.ca.gov) offer online record searches; other counties vary in online access.

Informational screening only — not legal advice. Confirm ownership with a licensed title professional before relying on any rights-status finding.
