By early 1907, the Hall of Records had been completed, but there was still not enough space for the city's important files; further, the city was paying large amounts for rent in private buildings. Officials pointed out that the cramped quarters of the city government's departments posed a fire hazard, and legislation had been proposed for a new municipal building. In July 1907, Lindenthal—who had already secured a new plot of land for the Brooklyn Bridge trolley hub—was authorized by the state legislature to host a fourth and final design competition for the municipal building. The Brooklyn loop line, a four-track subway line, was planned to be built under the site as well, passing through a large five-platform station at Chambers Street.
