In the 1935 code, Federal Highway defines the boundaries for both Fire Zone No. 1 and Fire Zone No. 2. For Fire Zone No. 1, the boundary is described as running parallel to and 100 feet west of the East line of Federal Highway, extending through subdivisions such as miami shores, Biscayne Shores, and Bay Ridge 1935-Miami-Dade-Building-Code_p85_104(p. 85). This designation places properties adjacent to the highway within specific regulatory constraints regarding construction and fire safety, specifically prohibiting occupancy-classification Type V construction in Fire Zone No. 1 1935-Miami-Dade-Building-Code_p85_104(p. 104).
