A July 1979 letter from planner Janis Snoey to FAA Airport Planning Branch representative George Sato transmits five pre-schematic site plans for the North Sea-Tac Park, showing projected peak-time visitor numbers under various development scenarios. The plans, prepared following an FAA meeting on July 17, 1979, are accompanied by a 'Carrying Capacity' map that classifies park areas by development suitability—from very high intensity (sports fields, motorcycle trails) to low intensity (foot paths only)—based on analysis of soils, hydrology, vegetation, and noise. The documents were intended solely to provoke discussion during the early master planning phase for the North Sea-Tac site.Open full document
