Seattle-Tacoma Intl (KSEA) has 3 runways. All three are concrete and all are 150 ft wide. The longest runway is 16L/34R at 11,901 ft. The shortest is 16R/34L at 8,500 ft. Runway headings are 180° and 0° magnetic on each runway pair.
This is a towered field with a 24-hour control tower. ILS is available on every runway end. That gives crews full precision approach coverage for 16C, 16L, 16R, 34C, 34L and 34R. No LAHSO notes are published for this airport.
Noise abatement guidance is published. Operators are advised to use minimum required thrust when taxiing near the terminal or aircraft parking areas. Consolidated taxi to takeoff is encouraged when practical, safe and available. Reverse thrust beyond what is needed for operational or safety reasons is discouraged. Noise abatement flight procedures are in effect between 2200 and 0600.

Traffic pattern
Pattern altitude is not published. For light piston operations, use the standard 1,000 ft AGL unless ATC assigns something different. Field elevation is 432.3 ft MSL, so that works out to about 1,432 ft MSL. This is a towered airport. ATC sequences the pattern.
Runway-specific pattern exceptions are not published in the facts. The published notes focus on tower control and noise abatement. Expect normal tower coordination for pattern work, arrivals and departures. Use the current FAA Chart Supplement for any airport-specific pattern direction or local procedures before flight.
Every end, one page
Each runway end has its own page with wind component, traffic pattern geometry and ILS for that specific direction.
