LIVERMORE -- The Livermore City Council on Monday approved a development of 31 two-story townhomes to be built in South Livermore.

Council members voted 4-1 -- with Councilwoman Laureen Turner casting the lone "no" vote -- to amend the city's general plan and allow a zoning change to allow construction of Catalina Crossing, slated for the southwest corner of Catalina Drive and Barcelona Street.

San Ramon developer Sunset Development Co. plans to raze the Livermore Financial Center, an office plaza with 33,600 square feet of office space built in 1971, to make way for the townhomes. The plaza's 16 remaining tenants will be given 90 days notice to vacate as soon as the construction schedule is determined, company officials said.

"We're pleased we got the majority vote of the council and we can move ahead," said Sunset's senior vice president Chris Truebridge. "I think it's very compatible with the neighborhood and provides a great opportunity for first-time homebuyers."

The developer's larger Sunset Crossing project, proposed for the northeast corner of Holmes Street and Concannon Boulevard but denied a recommendation by the Planning Commission, will likely go before the council at a future date minus its previously planned multi-family units, Truebridge said.

The company, he added, will begin working with neighbors to re-evaluate that project within the next 30 to 60 days.
