The new Nassau Bay fire station pays off in better emergency response, not only for that city but for neighboring communities, a department official says. The Nassau Bay Volunteer Fire Department receives about 30 calls each week, including those that involve assisting other communities, department administrative assistant Leslie Shak said. The $4.1 million facility, which had its grand opening in January as the city’s first fire station to be built since 1980, improves the department’s ability to provide mutual-aid response to neighboring cities such as Kemah, Seabrook, Webster and League City, she said. The 17,400-square-foot building at 18295 Upper Bay Road features advanced technology, four drive-through double-door bays, rooms for weekly training and a gym for staff and city employees. It also has living quarters — something previous Nassau Bay stations lacked.
