We meet and exceed all State of Michigan standards and requirements for archival storage. USC has maintained a legacy of secure protection for archival storage. We provide storage services for numerous states, cities, counties, businesses, courts, churches and libraries.

The microfirm archives are protected in a large vault within the gypsum mine located 10 stories underground. USC maintains archival compliant humidity and temperature standards within the vaults. Humidity is kept at 40% and the temperature is between 60-65 degrees Fahrenheit at all times.


The vaults are kept clean and the records are stored in labeled steel cabinets. Every single item placed in storage is carefully documented.
