The Uptown at Warner Center site was orginally developed in 1955 with industrial buildings by the United States Air Force for the manufacture of rocket engines and related systems, and since that time, it has been continuously used for industrial purposes related to aerospace design, engineering, manufacutring and assembly. The site was owned by North Amercian Aviation, Rockwell International, and The Boeing Company (Boeing) prior to UTC.

UTC acquired the site in 2004 with its acquisition of the Rocketdyne business from Boeing by UTC’s Pratt & Whitney business line. The site most recently served as the aerospace production plant of Pratt & Whitney/ Rocketdyne, producing rocket engines and propulsion systems for the U.S. space program. In 2013, Pratt & Whitney sold its business holdings in Rocketdyne to GenCorp, Inc., the parent company of the Aerojet Corporation, which then formed Aeroject Rocketdyne. UTC retained the ownership of the site in this transaction. Aeroject Rocketdyne leased the site back from UTC until April 2014 when operations and employees were relocated to Aerojet Rocketdyne’s nearby De Soto Avenue plant. Although the site will be delivered to the buyer cleared of all improvements/structures the plant was comprised of approximately 16 industrial and office buildings totaling a little less than 800,000 square feet that often times operated with multiple shifts. This plant was an integral part of United States’ aerospace history.

Conceptual Building Plan

Baseline Master Plan


  • All building footprints subject to change.
  • Each block will provide at least the amount of open space area listed on the diagram.
  • Each block will provide dual-axis through-block pedestrian connections.
  • Public Open Space includes sidewalk and parkway as well as interior greenscape and hardscape.
  • The proposed project includes the flexibility to move uses between blocks, as long as the environmental consequences remain within the envelope of impacts attributable to the proposed Project. Actual structures shall be subject to adopted WC2035 Plan compliance measures and maximum per block building heights, which may be up to two stories higher than indicated in this figure.
