In order to make space for up to 900 Keysight Technologies workers temporarily displaced by damage from the wildfires at its Fountaingrove headquarters, the owners of a former Hewlett-Packard facility in Rohnert Park have managed to relocate or consolidate eight existing tenants within the site.

Keysight, which traces its own lineage to HP’s test and measurement work, has leased 104,000 square feet at SOMO Village, the facility’s owners said Monday in a press release that offers new details on the technology company’s efforts to resume operations in the aftermath of the historic fires.

The Tubbs fire last month swept over the Fountaingrove neighborhood, including Keysight’s world headquarters.

Keysight’s four main buildings in Santa Rosa all sustained damage in the fire and are being repaired and cleaned, according to the press release from SOMO Village. The fire destroyed two modular buildings near the front of the campus.

The Santa Rosa headquarters opened earlier this month for a limited number of workers.

Keysight spokesman Jeff Weber said in an email Monday that in the weeks following the reopening, many production operations have resumed at the Santa Rosa headquarters facility.

He said the return of more workers there “will be phased through the rest of the year and into 2018.”

Keysight, the world’s largest electronics measurement company, has 1,300 workers in the county. Along with the Santa Rosa and SOMO Village sites, Keysight has about 100 workers at a temporary site in Petaluma.

Hewlett-Packard opened what is now SOMO Village in 1984, a year in which the tech company was Sonoma County’s largest employer with 3,900 workers. Agilent Technologies, an HP spinoff, announced in 2004 it would close the manufacturing facility during a painful downsizing here as production was shifted to Malaysia.

In 2005, Codding Enterprises announced it was purchasing the Rohnert Park facility and later transferred the property to SOMO Living LLC. The 30-acre facility includes 600,000 square feet of mixed-use office space and an events center.

Brad Baker, CEO of SOMO Village, said in the press release that the addition of Keysight workers in Rohnert Park became possible because his staff and tenants “all worked together during difficult times to support each other and our community.”

Mike Viskovich, a Keysight vice president, said in the release that SOMO Village quickly accommodated the company’s need for space.

“The speed with which we were able to secure efficient, professional work space helped us maintain business continuity seamlessly, ” Viskovich said.
