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.

Cisco leased the two four-story buildings back in October and has plans to buy and occupy a third, 93,000-sf building upon its completion in June. The buildings comprise Lincoln Centre. The only other occupant in the complex is Groundswell, and Internet services consultant.

Cisco has also tied up two office buildings under construction by Opus West in the Emerald Point business complex in Dublin, and a chunk of nearby land owned by Alameda County. Cisco has been making $250,000-a-month escrow deposits toward the land purchase, but now may delay the deal in light of the recent market slowdown. The company also is at least temporarily abandoning its search for space in Sonoma County to double the size of a 270,000-sf Petaluma campus.
