Aerial photograph showing a large retention or detention pond under active construction adjacent to what appears to be an airport runway and taxiway. Heavy equipment, graded earth, and what appear to be water treatment or stormwater management facilities are visible, consistent with airport infrastructure development or environmental mitigation work.

Aerial photograph showing a highway with a tunnel portal, a rectangular concrete structure with green equipment units, a newly constructed retention/settling pond with orange sandy margins, and an airport runway in the background. The site appears to be an active construction project, likely stormwater or noise mitigation infrastructure, situated between a major freeway and an airport airfield.

Aerial photograph showing an artificial retention or stormwater pond under active construction adjacent to a major airport runway complex, with construction equipment visible along the earthen berms. Industrial and commercial buildings are visible in the lower left, with airport taxiways, runways, and terminal infrastructure visible in the upper portion of the image.

Aerial photograph showing a retention or settling pond under construction near an airport runway, with associated site infrastructure including what appears to be a treatment facility or staging area to the left. The airport runway, taxiways, and terminal buildings are visible in the background, consistent with Sea-Tac Airport environs.

Aerial photograph showing a large white-roofed cargo or maintenance building adjacent to airport taxiways, with two elongated stormwater retention/detention ponds visible. Construction activity and heavy equipment are visible on the west side of the facility, and a busy multi-lane road intersection is visible to the east.

Aerial photograph showing a large oval retention or settling pond under active construction, with construction equipment visible along its perimeter. In the background, an airport runway and taxiway are visible, along with a large white aircraft maintenance or assembly facility bearing a partially visible red logo consistent with a major airline.

Aerial photograph showing a large retention/sedimentation pond under construction adjacent to an airport runway and taxiway, with active earthmoving equipment visible. A major road intersection, commercial warehouses, and parking areas are visible in the foreground, consistent with the industrial corridor south of a major commercial airport.

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 an airport runway (with visible threshold markings), a road tunnel/underpass passing beneath the airfield, a large retention or sedimentation pond under apparent construction, and surrounding industrial and commercial development. Fuel storage tanks are visible in the upper portion of the image, consistent with airport fuel farm infrastructure.

Aerial photograph looking north toward Seattle-Tacoma International Airport, showing a large rectangular stormwater or noise-mitigation detention pond under construction in the foreground, with airport runways, terminals, and aircraft visible in the background. Construction equipment, a temporary site office, and freshly graded sandy soil surround the pond, suggesting active civil works in the airport's peripheral area.
