The Lawrence Berkeley National Laboratory, which employs some 4,000 employees and conducts research on everything from DNA to climate change, may soon be looking for land to build a new facility.

The lab is in the early planning stages to consolidate its facilities - 20 percent of which are located outside the city of Berkeley, including sites in Emeryville, Oakland and Walnut Creek - into a new "second campus" somewhere in the East Bay, according to Sam Chapman, manager of state and community relations for the lab.
