This analysis of low flow impacts, and the propos=d facilities for offsetting identified Isnpacts, constimto a substantial proposal to provide mitigation for natural resource m_pscts which goes well beyond the basic requirements of the King County Surface Water Design Manual. Since this proposal goes beyond the requirements of the Design Manual, reviewers did not have the be=¢fit of clem"per/orJ_anc¢standards/or low flow mitigation efforts against which to measure the proposals. The enclosure provide= gcmer41comments on the low flow study, as well as specific comments on the analysis and proposed facilities grouped by drainage basin. To assist Ecology, substantial commentary hm bcen included to hclp clarify the reviewm-s' undersmading of the tccZuzicalissues and the logic contributing to specific comments, Reviewers did find several inconsistencies and gaps m data, primarily in the report documentation, that we reconmaend correcting in the final proposal's preparation. While most of these appear to be minor errors attributable to the mul_ple itcratsons and edits that the documenthasgonethrough, several of them have thc potential toaffect facilitydesign andplan effectiveness beyond…

U.S. Army Corps of Engineers _,_ _ Regulatory Branch, Seattle District Office 0 Box 3755 _: C'_"_P.O. Seattle, WA 98124-3766 Dear Ms. Walker: This is a followup to our letter to you of May 31, 2001, in which we indicated we would provide you additional information on issues related to new technologies; the mechanically stabilized earth (MSE) wall; and Section ! 06 activities, as noted in your April 30, 2001, Memorandum for the Record. We offer the following clarifying informatiorL a. New Technologies The Port of Seattle (Port) proposes the development of the third runway to address the airport's existing poor weather arrival constraints. The existing parallel runways at Seattle-Tacoma International Airport (STIA) have a centerline-to-centerline separation of 800 feet. Due to separation standards imposed by Air Traffic regulations, only during visual flight rules 1 (VFR1) conditions (good weather) are two arrival streams possible. In "just below visibility minimums" (VFR2) and under instrument flight rules weather conditions, the airport operates in a single arrival stream. Even with the introduction of current and future technology, the existing runway separations will prevent poor-weather- dual-arrival streams. This is because the existing runway separation criterion requires 4,300 feet to operate dual independent precision instrument approaches, and separations are allowed down to 3,400 feet only with predmion runway monitors (PRM). The Federal Aviation Administration (FAA) has considered alternative technologies to address this poor weather arrival constraint, as documented in the 1996 Final Environmental Impact Statement O/IS) and the 1997 Final Supplemental EIS. As we discussed…

This report examines the hydrogeologic and geotechnical issues related to design, construction, and operation of Pond A. Potential impacts to the hydrology of riparian wetlands between Pond A and Miller Creek can be mitigated through appropriate engineering design. Pond A will be excavated about 6 to 10 feet in wetland soils, and would have an operating water level roughly 0 to 10 feet below the current…
