MOUNTAIN VIEW -- LinkedIn and a developer have submitted proposals to city officials for multiple office buildings in Mountain View where the technology giant could employ up to 7,500 new workers, according to proposals submitted to city officials.

The buildings that LinkedIn at present is planning to occupy could total 1.5 million square feet, according to separate letters sent to city officials that sketched out the preliminary details of the office projects. That much square footage typically could accommodate up to 7,500 employees.

"This would be a major increase in LinkedIn's presence in Mountain View," said Terry Blount, the city's planning manager.

Mountain View-based LinkedIn, a social networking website for professionals, has been on an expansion binge lately, with new offices in San Francisco and Sunnyvale. Now, the tech giant is focused on growth in its hometown.

"Due to LinkedIn's success and explosive growth, but constrained by the amount of office space available to us locally, we have had to expand outside of Mountain View," James Morgensen, head of global work space for LinkedIn, wrote in a letter to the city. "It has always been our desire to retain our headquarters in the North Bayshore area and to remain a high value Mountain View-based company."

In late April, LinkedIn signed a lease for a 26-story, 450,000 square feet office tower in San Francisco. In February, it moved into a 120,000-square-foot building in Sunnyvale, where "several hundred" of its employees work, said Doug Madey, a LinkedIn spokesman. A building that size typically would accommodate 480 to 600 workers.

It makes sense for LinkedIn to expand in its current home territory of Mountain View, said Tim Bajarin, principal analyst with Campbell-based Creative Strategies, which tracks the tech sector.

"The concentration of tech talent is still in the South Bay, in the heart of Silicon Valley," Bajarin said. "Any company that wants to attract that tech talent has to be centrally located. The South Bay still has the highest concentration of where tech engineers live."

According to LinkedIn's letter to Mountain View, the company is eyeing a redevelopment project near the corner of Shoreline Boulevard and Stierlin Court in Mountain View's North Bayshore area. LinkedIn is planning to work with a realty investment trust, HCP to develop up to 800,000 square feet of offices on one of two parcels at that site. More square footage would be develop on the other parcel but LinkedIn spokesman Hani Durzi said the company at present has no plans to expand to the second parcel.

Separately, LinkedIn is planning for another office complex at 1400 N. Shoreline Blvd. north of U.S. 101 that would total 695,000 square feet, according to a letter submitted by an architect on behalf of Rubicon Partners, which owns the site.

If approved by the city, the LinkedIn expansions would likely occur in phases, Blount said. He estimated that the company at present occupies about 767,000 square feet in Mountain View.

Despite San Francisco's success in attracting tech companies, industry watchers say locations such as Palo Alto, Mountain View, Sunnyvale, Santa Clara and north San Jose will continue to be attractive.

"Even if the employees live in San Jose, or Morgan Hill or Gilroy, a commute to Mountain View is manageable," Bajarin said. "But if they work in San Francisco, that's a serious commute."
