A Central Coast Bank plans to expand it’s headquarters. Santa Cruz owned Lighthouse Bank says it wants to invest 4-million dollars and buy an empty downtown bank branch on Pacific Avenue. The six year old bank is expected to expand from it’s current 5,400 square foot location to 8,500 feet in the new building, which will be completely renovated to accommodate a staff of 35. The Bank’s current employee count is 22. Work on the new location is expected to begin next year.
