The Highline Wetlands Aerial Photo Album, compiled in September 2003, presents a collection of aerial photographs documenting wetlands, lakes, and waterways in the Sea-Tac Airport area of Washington State. The album covers locations including Miller Creek, Walker Creek, Lake Burien, Angle Lake, and other water resources affected by the proposed Third Runway construction at Seattle-Tacoma International Airport. An accompanying map illustrates the runway's projected impact on local water resources, identifying proposed fill areas and the third runway site relative to surrounding communities such as Burien, Normandy Park, and Des Moines.

This document outlines wetland mitigation calculations for the Vacca Farm site, detailing compensation actions such as wetland restoration and enhancement across various locations including Lora Lake and prior converted croplands. Adjustments were made to credit acreages based on state ecology findings and documentation gaps; for example, the 6.60-acre converted cropland credit was reduced to 3.30 acres because the state identified those areas as existing wetlands requiring enhancement ratios rather than restoration ratios. In total, the site's original 10.48 credit acres were adjusted down to 5.61 acres after accounting for these regulatory and documentation considerations.
