Berkeley Lab received 21 submissions for possible sites for a second campus, according to Jon Weiner, a lab spokesman.

Eight East Bay cities, including Berkeley, Oakland, Albany, Richmond, Alameda, Walnut Creek and Dublin pitched sites for the new campus, according to various news reports. The proposed sites include a 30-acre swath of land adjacent to Golden Gate Fields, two different areas near Aquatic Park, four sites in Oakland, a joint Berkeley-Emeryville site and many more.

The lab plans to narrow the list down to as few as four sites by April, with the goal of selecting a final site in June. The lab would not move onto the new campus until 2015.

Berkeley Lab wants to consolidate the facilities it has spread out around the East Bay. The new site should accommodate as much as two million square feet in office and laboratory space and a 3,000-foot long space for a new Advanced Light Facility, according to the lab’s Request for Qualifications.
