    BANGR Nine Departure (RNAV) — Seattle-Tacoma International Airport (SEA)

    The BANGR Nine Departure is a standardized instrument departure procedure (SID) for pilots flying out of Seattle-Tacoma International Airport (SEA), directing aircraft on specific headings and altitudes depending on which runway they use. Aircraft departing on northbound runways (34L, 34C, 34R) climb to at least 932 feet before routing through waypoints like CUSBU, NESOE, or DODVE, crossing WUREL at or above 3,100 feet, while southbound runway departures (16L, 16C, 16R) follow similar climb profiles through waypoints like CAVOB, OTLIE, or WESET, crossing RENBE at or above 3,000 feet. All routes converge at the BANGR waypoint, which must be crossed at or above 10,000 feet, with specific minimum climb gradients established to manage aircraft noise and terrain clearance in the surrounding communities.

    F.A.A. density guidelines: North Sea-Tac Park

    This document presents FAA density guidelines for the North Sea-Tac Park area near Seattle-Tacoma International Airport, showing recommended population limits per acre across different zones.

    North Sea-Tac Park planning maps: Passive, modified passive, active/passive, and active options

    This document presents four conceptual land-use plans for North Sea-Tac Park, ranging from 'Passive' to 'Active' configurations, each showing different proposed recreational facilities such as tennis courts, golf courses, archery targets, baseball fields, and exercise trails. Handwritten annotations question the fate of certain features, including the Highline Athletic Complex and a 'little league field,' and note that a golf course of approximately 120 acres was considered in connection with Boulevard School and Club Moore. The plans appear to be early planning documents exploring how the park land could be developed or preserved under varying levels of recreational activity.
