The second phase of construction at Lake Highlands High School is set to begin in late spring or early summer, according to district staff. Board trustees approved $22.6 million for the project at a March 4 meeting. Items reflected in the cost include a new, larger cafeteria; a new, redesigned library; and a building that will connect the two facilities. The cost also includes upgrades to mechanical and electrical systems as well as utility work. The project is being bid in three phases, Board President Justin Bono said. Phase 1, approved in December at a cost of $61 million, added a new multipurpose activity center to the campus. Assistant Superintendent Sandra Hayes said Phase 3 will include construction of a city-mandated storm shelter and additional classrooms as well as a renovation of the Career and Technical Education hallway. The renovations will be delivered in three phases. Construction began in January and will wrap up at the end of 2020. A cost for Phase 3 improvements will be brought before the board for approval this summer, Hayes said.
