Chet Holifield Federal Building



The Chet Holifield Federal Building (CHFB), commonly known as "the Ziggurat Building," was originally built in 1970 by the Aerospace and Systems Group of North American Rockwell Corporation. It was never occupied and was transferred to the federal government for use by federal agencies in March of 1974.  It is managed by the United States General Service Administration (GSA). The building is approximately 1 million square feet in size and is located on an 86.5-acre parcel at 24000 Avila Road. An associated 5.5-acre parcel containing a central utility plant for the building is located north of Avila Road. Collectively, the site is 92 acres in total area.


The CHFB is home to various federal agency tenants, with the United States Citizenship and Immigration Services (USCIS) serving as the largest tenant. According to GSA, as a result of the age and current condition of the building, the working space for their tenants does not met applicable building code, accessibility, and security standards. The purpose of the proposed action is to accommodate the long-term office space requirements for the tenants. The GSA has prepared a Final Environmental Impact Statement (FEIS) to analyze the potential impacts of the proposed action.


This engagement is planned and administered exclusively by the U.S. General Services Administration (GSA). The City will conduct and engage residents in its own outreach for land use in the future.

The GSA prepared a FEIS, which examines the:

  • Purpose and need for the removal and relocation of existing tenants,
  • Alternatives considered,
  • Existing environment that could be affected,
  • Potential impacts resulting from each of the alternatives and
  • Proposes best management practices and/or mitigation measures.

The FEIS is available for viewing here

Alternatives to be Considered in the FEIS:

The FEIS considers two “action” alternatives and one “no action” alternative:

“Action” Alternative No. 1 would involve construction of a new federal office building within the 86.5-acre parcel, directly adjacent to the existing CHFB for the USCIS and relocating all other tenants into lease space primarily within the Orange County market. The existing building and the remainder of the property not retained for construction of the USCIS building would be reported as excess in accordance with federal policy and disposed.

“Action” Alternative No. 2 would involve relocation of all tenants primarily within Orange County similar to as under Alternative 1, but to also include a new location for the USCIS outside of the existing CHFB property. The existing CHFB and surrounding government property would be reported as excess in accordance with federal policy and disposed. Alternative 2 has been identified as the “Preferred Alternative” in the FEIS. 

“No Action” Alternative No. 1 assumes that tenants would remain within the existing CHFB and no new construction or relocation would occur. Minor repairs would occur as needed and maintenance and operation of the existing facilities would continue. 

The GSA held a virtual public meeting for the Final EIS on Tuesday, March 16, 2021 from 4:30 pm to 6:30 pm Pacific Time to garner public input on the different alternatives. 

Public Comments

After the virtual public meeting, public comments on the Final EIS were accepted by GSA until Wednesday, April 7, 2021. The City’s comment letter is available for viewing here.
