A dance studio and costume shop are set to be added to Long Beach City College’s auditorium as part of a renovation project.

A groundbreaking event for the project is scheduled for Thursday morning, according to a campus announcement. College officials plan to spend revenues from the bond sales approved by the passages of Measure E and Measure LB to pay for the construction.

Announcements from the project’s architects and college reported estimated costs topping $25 million.

The campus’ auditorium was built in the mid-1950s, and the project’s SVA Architects reported plans call for a total redesign of the building’s entryway, lobby and restrooms. Improvements to seating and backstage areas are also on the project’s to-do list.

The groundbreaking is scheduled to begin 10 a.m. Thursday outside the campus Auditorium, Building J at the college’s Liberal Arts Campus, 4901 E. Carson St.
