    ELMAA Four Departure (ELMAA4.ELMAA) — Seattle-Tacoma International Airport Standard Instrument Departure

    The ELMAA Four Departure is a standard instrument departure procedure for Seattle-Tacoma International Airport (SEA) that routes aircraft southward after takeoff on runways 16L, 16C, or 16R. Departing aircraft climb on headings of 161°–165°, cross the PEAKK waypoint at or above 3,000 feet, then turn right to intercept the SEA R-230 radial toward the ELMAA fix, with onward transitions available to Hoquiam (HQM) or Corvallis (CVO). Notably, departures from runways 34L, 34C, and 34R are not authorized due to noise abatement restrictions, and minimum climb gradients of up to 560 feet per nautical mile are required depending on the runway used.

    Sea-Tac Communities Plan: West Reinforcement Area Map (Section 6.6.5)

    The Sea-Tac Communities Plan, sponsored by the Port of Seattle and King County, maps the West Reinforcement Area surrounding Seattle-Tacoma International Airport, identifying neighborhoods such as Hazel Valley, Chelsea, Seahurst, Gregory Heights, Sunny Terrace, and Blakley Manor that are affected by aircraft noise. The map highlights the Burien Center commercial core, grid cells where program eligibility is determined by noise criteria alone, and features such as streams, ponds, and heavy vegetation. It distinguishes between single-family residential structures and other buildings to guide noise mitigation and land-use planning efforts in the impacted communities.
