Two of 10 buildings on the Alviso campus near Highway 237 and Grand Avenue are being left partially completed. In Fremont, city official learned last week that Cisco would not be breaking ground on its 3.4-million-sf campus until next fall at the earliest. The Fremont campus comprises 45% of Catellus Development Corp.'s Pacific Commons business park.

With a five-year window to start construction, Cisco said plans have no changed with regard to its would-be $ 1.3-billion world headquarters in North Coyote Valley on the south edge of San Jose.

In March, as a result of a deal that began before its sales began slumping with the economy, Cisco Systems closed on the acquisition of two suburban office buildings totaling 230,000 sf for $69 million. The seller was Lincoln Property Co., a Dallas-based developer and investor.
