SAN DIEGO - Members of the Board of Supervisors are scheduled to break ground Wednesday for a building that will house the San Diego County Registrar of Voters Office.

The nearly 120,000-square-foot structure will replace an inefficient warehouse-style building that the registrar's office has used since the 1970s, according to the county.

The building, set to open in one year, will be located across from the County Operations Center in Kearny Mesa. It will be designed specifically to handle election services, be more secure and be energy-efficient.

The building will also have a mail center to distribute letters to various departments, according to the county.
