Howvr, th landfill is closd and a mthan gas collction systm is in plac, and it is assumd that thr is also lachat collction. Furthr, a landfill typically has an nginrd covr. Potntial issus associatd with construction of th road ovr th landfill includ: Damag to th nginrd landfill covr during construction; Installation of ground improvmnt masurs or structurs through th landfill could caus a prfrntial pathway for groundwatr contamination; Th xisting mthan and lachat collction systms will nd to b considrd during dsign and construction; Accss to th primtr landfill road would nd to b maintaind; Loading of th landfill could caus changs in th way that lachat and mthan ar collctd; Th dsign of th road ovr th landfill may nd to includ mthan mitigation masurs; Construction of th road would nd to tak into account spcific hazards of working on a closd landfill with rspct to th halth and safty of workrs; and Th landfill likly has an approvd closur plan.

In aras whr any significant filling is proposd, th subsurfac conditions will plac constraints rlatd to stability, sttlmnt and sismic prformanc. Significant and long-trm sttlmnts should b xpctd du to comprssion and dtrioration of th organic soils and rfus. It should b anticipatd that fill hights will b limitd and/or xtnsiv us of lightwight fills will b rquird whr significant grad changs ar considrd in th aras south of Highway 1. Structurs should b supportd on pils baring within th firm ground. A primary considration for this sgmnt is th crossing of th landfill. Th dtails and proprtis of th landfill ar not prsntly known to us; howvr, factors that nd to b considrd includ: Th unprdictabl natur and long-trm dcomposition of th rfus, which may includ voids Potntial damag to th landfill lining, lachat and mthan gas collction systm Nd to collct and vnt gas Approachs to road construction in such aras includ dp compaction/tratmnt of th rfus to collaps voids and rduc comprssibility, provision for ongoing sttlmnt and ongoing maintnanc, and provision of xtra long sttlmnt ramps to accommodat diffrntial sttlmnt btwn pil and grad-supportd facilitis. 3.3 Option C Environmntal Th untt Rivr, Nlson Crk and th Frasr Rivr ar salmon-baring watrcourss.

Th City of Coquitlam has assignd larg aras adjacnt to Highway 1 and th untt Rivr with 30 m SPEA. Th majority of th proposd work along Highway 1 and untt Avnu adjacnt to th highway appars to b locatd within an idntifid SPEA and may rquir furthr rviw and approval by th City of Coquitlam. Th City of Nw Wstminstr has lablld th untt Rivr and larg sctions of th Frasr Rivr shorlin as ESLs.

Sit spcific mitigation may b rquird Environmntal Considrations Spcific to th Cut and Covr Tunnl Thr ar spcific and uniqu issus and considrations for th planning and construction of th cut and covr tunnl undr th untt Rivr. Ths includ: A DFO Rviw and likly Authorization undr th Fishris Act for srious harm rsulting from construction of th tunnl through th untt Rivr channl. This would triggr dtaild rquirmnts for habitat offstting and long trm monitoring; and An Approval undr th Watr Sustainability Act; th Approval application would b subjct to rviw by svral othr agncis as wll forwardd to potntially affctd First Nations.

Assssmnt of th potntial for contamination migration from adjacnt proprtis to th road alignmnt during construction will b rquird Gotchnical Considrations rlatd to Cut and Covr Tunnl at Sapprton Construction of a cut and covr tunnl in th vicinity of Cumbrland and Columbia would b xtrmly challnging. Th ground conditions ar poor and thr ar numrous abov- and blow-ground obstacls, including: Indications ar that firm ground drops off towards th ast and may b 10 to 15 m blow ground ast of th SkyTrain guidway. Th soils ovrlying th dnsr ground ar xpctd to compris wak silts/clays with organics and sandy intrlayrs. Th groundwatr is xpctd to b within 1 to 2 m of ground surfac, and artsian prssur should b anticipatd within th undrlying dns strata. As-built drawings indicat that th SkyTrain guidway is supportd on 2.4 m diamtr caissons having tip lvations in th rang of 13 m to 16 m or 17 to 20 m dpth, which is marginally dpr than th proposd tunnl. No dtails ar availabl on th caisson dsign or construction, but it is likly that th foundation systm obtains most of its support within th lowr 6 to 8 m of th caissons. Without prior support by undrpinning and/or suitably-dsignd diaphragm walls, any xcavation within th zon of influnc could impact th foundation support for th guidway. Th tunnl would pass bnath two activ railways, rquiring tmporary support and/or shut down of oprations. Th tmporary shoring and dwatring systm would hav to support th wak soils and addrss th groundwatr prssurs. This combination would likly rquir a diaphragm wall approach (scant pil wall, CSM, tc.), which would b capabl of bing kyd into th dns strata to provid both support and a hydraulic cut-off. An altrnat approach (possibly jt grouting) would b rquird to provid latral support to th wak soils undr th railway tracks, vn if th tracks ar indpndntly supportd. Givn th vry limitd horizontal and vrtical claranc, combind with th soil and ground watr conditions, th fasibility of constructing th support systm adjacnt to th SkyTrain guidway caissons and oprational railway tracks nds to b carfully valuatd. Undrpinning or additional tmporary support of th guidway may b rquird if th construction impacts prsnt unaccptabl risks. Th sgmnt which crosss a branch of th untt Rivr would likly involv tmporarily filling th channl, followd by construction of th cut-off walls, and thn xcavation. Dpnding on th gomtry of th rstord channl, anchoring could b rquird in this ara to balanc buoyancy forcs. It is possibl that th northwstrn approach at Columbia might b within mor comptnt strata whr mor cost-ffctiv soil nailing shoring tchniqus may b fasibl. Buoyancy considrations may rquir anchoring of th compltd tunnl to prvnt uplift of dpr sctions of th compltd tunnl, whil structural support or ground tratmnt may b rquird at th shallowr approachs whr thr will b a nt incras in load. A numbr of major undrground utilitis will nd to b protctd or r-alignd to accommodat tunnl construction, including is a major MV intrcptor swr. 9/12

10 Kn Curry L-Rv1 Parsons Inc. 16 Novmbr 2016 Thr is always som risk of damag to narby facilitis du to xcavations, ground dformations and/or modifications to th groundwatr rgim; howvr, us of a wll-dsignd diaphragm wall systm would hlp minimiz such impacts. 4.0 CONCLUSION This projct is xpctd to ncountr a numbr of constraints du to plannd works with potntial for ffcts to th Frasr Rivr, th untt Rivr, and Nlson Crk. Th Frasr Rivr and th untt Rivr ar idntifid as nvironmntally snsitiv aras that ar xpctd to initiat various lvls of agncy rviw. Th mitigation option that includs construction of a cut and covr tunnl undr th untt Rivr is xpctd to b significantly constraind with rspct to potntial nvironmntal ffcts and rgulatory rquirmnts; it will also prsnt vry significant gotchnical and constructability challngs. Construction across th Coquitlam Landfill sit will also prsnt significant nginring and nvironmntal challngs. Ground improvmnt and us of lightwight fill matrials ar likly to b rquird to achiv accptabl long-trm sttlmnt prformanc.
