    Zoning Map: North Sea-Tac Park Area, February 1979

    This is a zoning map dated February 1979 for section W 16-23-4, showing land use designations—primarily RS-7200 (single-family residential) and A.O.U. (Airport Operations Use) zones—in the area south of S. 128th Street near Seattle-Tacoma Airport. Handwritten annotations raise questions about passive park designations, proposed AOC/AOU classifications near Tub Lake, buffer distances (50-foot and 45-foot buffers are noted), and the status of an RS-7200 trailer storage site. The notes suggest an active policy review regarding how airport-related zoning categories and noise buffers should be applied to residential and transitional parcels in this neighborhood.
