Aerial photograph showing a highway corridor with a tunnel underpass beneath an airport runway, alongside active construction including a retention/detention pond, a rectangular concrete structure or basin, and portable site facilities. The airport runway and surrounding developed areas are visible in the background, consistent with infrastructure work in the Sea-Tac Airport vicinity.

Aerial photograph showing an overpass bridge crossing a multi-lane highway, with active construction visible including excavation equipment, earthwork, and staging areas on the northeast quadrant of the interchange. Surrounding area includes residential neighborhoods and dense tree cover, consistent with the Pacific Northwest region.

Aerial photograph looking north toward Seattle-Tacoma International Airport, showing a runway and taxiway system in the mid-ground, a large retention/stormwater pond under construction in the middle distance, and commercial/industrial development in the foreground. The Boeing manufacturing facilities and Renton area are visible in the upper background, consistent with the airport's geography south of Seattle.

Aerial photograph showing a large graded earthen mound or landfill with terraced slopes, construction equipment visible at base, adjacent to what appears to be an airport taxiway or runway in the upper right. Dense tree cover surrounds the site, with access roads and active ground disturbance visible.

Aerial photograph showing large-scale earthwork and grading operations adjacent to what appears to be an airport runway (visible at top). The scene includes rectangular water/sedimentation basins at lower left, heavy equipment, disturbed soil, and surrounding residential and forested areas consistent with airport expansion or noise mitigation land acquisition activity.

Aerial photograph showing active earthmoving and grading operations on a large cleared site next to what appears to be a general aviation airport runway. A retention or sedimentation pond is visible to the left of the construction area, with heavy equipment scattered across the graded terrain and a suburban landscape visible in the background.

Aerial photograph showing a multi-lane highway running north-south through a forested area, with active construction and heavy equipment visible alongside the roadway. In the background, an airport airfield with runways and large industrial/hangar buildings is visible to the upper left, consistent with the Sea-Tac Airport vicinity.

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.
