CONCORD (CBS13) – Homeland Security says it has no plans to build a massive detention facility in Concord or anywhere in California.

The city council held a meeting after a leaked draft memo raised the possibility of the former Concord Naval Weapons Station being converted into a migrant housing facility.

According to the reported proposal, up to 47,000 immigrants could be housed in the development.

Even though it was unconfirmed, the possibility sparked outrage and protests – prompting the mayor to write a letter to the Navy opposing the possible facility.

A Time Magazine report named several bases across the country as possible immigrant holding centers. The Concord facility and Camp Pendleton near San Diego were the two sites named in California.
