Aerial photograph showing a large oval retention/detention pond under construction adjacent to airport runways, with active grading and earthwork visible to the east. The image also shows Boeing or similar aviation facility buildings, taxiways, and surrounding commercial/industrial development consistent with the Sea-Tac Airport area.

Aerial photograph showing a gravel yard with rows of stored equipment or materials, adjacent roadways, utility transmission towers on the left, and surrounding vegetation. The site appears to be an industrial staging or storage area near a highway interchange, consistent with construction or infrastructure operations in the Sea-Tac Airport vicinity.

Aerial photograph showing large-scale earthmoving and grading operations on an expansive cleared site, with what appears to be sedimentation or detention basins visible at left, heavy equipment in operation, and residential properties and tree lines bordering the construction zone. A highway or arterial road runs along the left edge of the frame.

Aerial photograph showing a large engineered stormwater or detention pond under active construction adjacent to what appears to be Sea-Tac Airport, with a runway, terminal buildings, and aircraft visible in the background. Construction equipment, temporary structures, and disturbed soils are visible around the pond perimeter, suggesting this documents infrastructure development in the airport vicinity.

Aerial photograph showing Sea-Tac Airport's runway complex, terminal area, and cargo/maintenance facilities, with a large surface parking lot in the foreground and Puget Sound visible in the background. The image appears to date from the late 1970s or 1980s based on vehicle styles and airport infrastructure visible.

Aerial photograph showing active construction activity adjacent to an airport runway, featuring a large retention or detention pond with sandy berms, a flat-roofed structure under development, road infrastructure with a tunnel underpass, and commercial/parking areas in the foreground. The proximity to runway markings and airport taxiway infrastructure is consistent with Sea-Tac Airport environs.

Aerial photograph showing a gravel staging or storage yard with rows of materials or equipment, dirt access roads, dense tree cover, and what appears to be airport runway infrastructure visible in the upper left background. A power transmission structure is visible on the left edge, and several vehicles and trailers are present on the site.

Aerial photograph showing large-scale ground clearing and grading operations adjacent to what appears to be an airport runway or taxiway area in the upper portion of the frame. A residential neighborhood, road intersection, and what may be a water treatment or detention facility are visible in the foreground, with heavy construction equipment scattered across the disturbed soil areas.

Aerial photograph showing a large retention/detention pond under construction on the south or west perimeter of Seattle-Tacoma International Airport, with active earthmoving equipment and grading visible to the right. Airport runways, terminal buildings, and parked aircraft are visible in the background, consistent with Sea-Tac Airport infrastructure documentation.

Aerial photograph looking northward over Seattle-Tacoma International Airport, showing the parallel runway complex, terminal and cargo areas on the west side, a large airport parking lot in the foreground, Interstate 5 running across the middle ground, and Puget Sound visible in the background. The image appears to date from the 1990s based on infrastructure and vehicle styles, and is consistent with noise-policy documentation of the airport's runway layout and surrounding land use.
