Port of Seattle: Projects, Third Runway, Sea-Tat Airport, Protected Fish Page 1 ot t Third Runway Construction ls a Work in Progress The fill material needed to raise the third runway up to the current airfield elevation continues to be delivered to the airport via established routes. In order to expedite this delivery and keep trucks off local roads, work has started on temporary on/off ramps connecting South 176th Street and Highway 509 for the delivery vehicles. The project includes building retaining walls to support the ramps, placing fill material, building a storm water detention pond to control runoff, paving, and widening a portion of the shoulders along Highway 509 to accommodate the ramps. A timber "noise wall" is being built as a buffer between trucks using the ramps and a few houses in the vicinity. There will be some limited night work and occasional daytime lane closures on 509 during construction. The project is scheduled for completion by October. The contract for supplying 1.9 million cubic yards of fill this year was awarded to City Transfer of Kent. The delivery of this amount is not dependant upon issuance of environmental permits for the projects. Regulatory agencies are still reviewing the Port's permit application. The current contract also calls for delivery of an additional 485,000 cubic yards once the permits are approved. top of page - AR 028013 http ://www.portseattle.org/seatac/projects/3runwayconstruction.htm 9/10/01 EXH0774028013 EXH0774028014

SUBJECT: Reviewof "Low FlowAnalysis, Flow Impact OffsetFacilityProposal, Port of Seattle" ParametrixInc., July 2001 This memo is to documentmy reviewof the report, "LowFlowAnalysis,Flow Impact Offset Facility Proposal" preparedfor the Port of Seattleby ParametrixInc., (July2001). This most recent report presentsconsiderableimprovementsin analysisand mitigationfor predictedimpactsof the proposed third runwayon latesummerstreamflows. I alsoread reviewcommentsonthe Port's Low Flow Analysisby KingCountyDepartmentof NaturalResourcessentto Ann by PareBissormette with a cover letter datedAugust3, 2001 (DNR,August3, 2001). An earlierlow flowanalysisprepared for the Port, "Sea-TacAirport Master Plan Update Low StreamflowAnalysis" (EarthTectt December2000), usedthe term"low streamflow"to refer to total flow in localstreamsduringAugustand September,since thosemonthswere considered the most criticalfor minimumstreamflows. ARerre-evaluating47 years ofstreamflow records for Mi'ler, Walker andDes Moinescreeks,this more recentanalysis usesa 3-monthperiod for proposed low-flow augmentation.This provides a marginof safety for futureclimaticaberrationsand, as pointed out by King CountyDNR,constitutessubstantialstreamflowmitigationfor the third runway project. In a special studycommissionedby the 1998 legislature,Pacific GroundwaterGroup de;eloped a "slice mc.del"to quantifythe hydrogeologicbehaviorof the proposedrunwayfill over a characteristic cross-sectionin "Sea-TacRunwayFill HydrologicStudiesReport" (PGG,June2000). The slice model predictedthat infiltrationof precipitationintoperviousareas&the runway fill duringwinter monthswould result in summerdrainagefromthe embankment. Sul';equentlow f_owanalyses, (Earth Tech,December2000), integratedthe results of the PGG slice modeiover the 5,400-footembankment distancealong MillerCreek. Becausethe cross-sectionoft.he June 2000 'slice model"was locatedat an uncharacteristicallythick sectionof the :_11at the proposedMiller Creekretention wall, the groundwaterflowcharacterizedby integratingthe original'slice' along the length of the embankznent adjacentto Miller Creek was thoughtto be unrepresentative.Accordingly,the subject re-ev_luat!_mcf embankmentdrainageandother factorseffectingthe drainage(Parametrix,July 2001) takes several representativeembankment'slices' intoaccount andprovidesmorereasonablefill drainage_stimates for the HSPFstreamflowmc-lels.
