The Renovation and Expansion of Griffith Observatory

After nearly 67 years of heavy public use, Griffith Observatory closed its doors in 2002 for a comprehensive renovation and expansion, the first major capital improvement to the building since it opened in 1935.

The effort started in 1978, with the creation of Friends Of The Observatory (FOTO) by Observatory Director E.C. Krupp and Debra and Harold Griffith (Harold was Griffith J. Griffith’s grandson). Planning for the renovation and expansion project began in 1990 with development and approval of a Master Plan. Throughout the 1990s, FOTO worked with the City to secure the baseline public funding needed to get the project underway, though a substantial amount of the total funding for the project ended up coming from private contributions to FOTO. With architects hired in 1997, the City and FOTO established a unique public-private partnership focused on four primary goals: renovation; expansion, planetarium; and exhibits. The Governor of California, Mayor of Los Angeles, and other public officials broke ground for the project on October 30, 2002, and construction started soon thereafter. Theater and exhibit installation took place mostly in 2004-2006. The building reopened to the public on November 3, 2006.

Expand public space to improve the visitor experience.

Nearly 40,000 square feet of public space have been added to the existing building primarily by excavating under the front lawn and west terrace. Additions include a large, multi-level exhibit gallery, a 200-seat presentation theater (Leonard Nimoy Event Horizon), classroom, café, bookstore, and new entrances and ramps to improve access to/in the building.

With a new dome, star projector, digital projectors, seats, sound system, and lighting, the 290-seat Samuel Oschin Planetarium theater is the finest planetarium in the world.

Griffith Observatory was originally conceived by some of the finest scientific minds of the 1930s and built with the finest materials of the day. The City of Los Angeles and Friends Of The Observatory were committed to that spirit of excellence in every aspect of the renovation and expansion project. The ambitious $93-million project renewed the Observatory’s world-class standing and restored and enhanced the Observatory’s ability to pursue its public astronomy mission, all driven by a commitment to excellence and enabled by a successful public-private partnership.

Project Budget

The total cost of the renovation and expansion project was $93 million. Roughly 70 percent of this total $66.5 million) went toward construction-related costs, which include architectural design and drawings. The balance was for exhibit development ($14.8 million), planetarium equipment and show production ($8.5 million), and other expenses (3.2 million). Both public ($67.4 million) and private ($25.6) sources provided funds for the project. Friends Of The Observatory (FOTO) directly raised nearly a third (over $30 million) of the required funds and also participated actively in securing much of the other funding for the project.

Public-Private Partnership

The renovation and expansion of Griffith Observatory was a singularly successful public-private partnership between the City of Los Angeles Department of Recreation and Parks, which owns and operates the facility, and Friends Of The Observatory (FOTO), the Observatory’s non-profit support organization. Major participants (and primary roles) in the renovation and expansion project include:

  • Los Angeles Department of Recreation and Parks (project management, building operation).
  • Los Angeles Department of Public Works (construction management), through its Bureau of Engineering.
  • Pfeiffer Partners, Inc. (principal architect), Levin & Associates Architects (associate architect), and S. J. Amoroso Construction (building construction general contractor) were the major contractors for the building and construction project.
  • Friends Of The Observatory (FOTO) (fundraising, specialized equipment acquisition, exhibit program management and acquisition).
  • C&G Partners LLC (exhibit designers), Maltbie, Inc. (exhibit general contractor), Carl Zeiss Jena GmbH (star projector), Evans & Sutherland Computer Corporation (digital projectors), and Spitz, Inc. (Samuel Oschin Planetarium dome) were the major exhibit and equipment contractors.
  • Public leadership was provided by Los Angeles Mayors James Hahn and Antonio Villaraigosa, Congressman Adam Schiff, Assemblymember Dario Frommer, Los Angeles Chief Legislative Analyst Ron Deaton, and by Los Angeles Councilmember Tom LaBonge, who was the tireless advocate for the Observatory and the project for decades.
