This document presents site features and cross-sectional diagrams used for Hydrus-Slice hydrological modeling of the Sea-Tac Third Runway Embankment Fill project. It shows fill depths ranging from 0 to 160 feet across multiple modeled slices, with cross sections identifying impervious areas, elevation contours, and the watershed divide between Miller Creek and Walker Creek. The figures were produced in November 2001 as part of environmental engineering analysis for the third runway construction.

Respondent Washington State Department of Ecology’s objections filed before the Pollution Control Hearings Board (PCHB No. 01-133, PCHB No. 01-160) to issues proposed separately by Airport Communities Coalition (ACC).

A 2001 technical memo from Hydrocomp, Inc.'s Norm Crawford outlines recommendations for hydrological modeling of Miller, Walker, and Des Moines Creeks near Sea-Tac Airport's new runways and taxiways. The document describes how surface runoff and groundwater flow from both impervious runway surfaces and surrounding pervious grasslands should be calculated and linked across three modeling tools: HSPF, Hydrus, and the Slice model. Key recommendations include properly accounting for infiltration, reducing till seepage by 33% for inactive groundwater recharge, and reconciling discrepancies in land area calculations between the different models.

Draft map prepared by Parametrix, Inc. on November 07, 2001, AR 051191. The document is a draft aerial/planning map showing what appears to be the Sea-Tac Airport area and surrounding communities, with various zones, boundaries, and site designations marked. Labeled as draft and subject to change.

A November 6, 2001 handwritten fax note discusses problems with noise modeling errors and how results will be integrated into legal policies. It notes that AK advised POS to produce a more complete and accurate document, and argues it is not reasonable to hold up port mitigation based on a mistake, stating that if there is no impact, there is no impact. The note also references consultant agreement on impact calculations and requirements related to 401 regulations submitted as group per FAA standards.
