Ma ʻAukake 18, 1997, ua hoʻolauleʻa ka Port of Los Angeles a me ka US Army Corps of Engineers i ka Pier 400 Project, ka papahana dredging a landfill nui loa ma USA, e hana ana i nā kahawai hohonu e ʻae i nā moku nui loa o ka honua a me nā moku tanker e komo i ka Port's. 300 Piers hou a me 400.
E hoʻohana ʻia ka mea i kahakaha ʻia mai ka hana kahawai no ka hoʻohui ʻana ma kahi o 600-eka (242.8 hectares) i loko o ka Port e kōkua i ka hoʻolauna ʻana i nā pālua i hiki ke neʻe i ka Port ma nā makahiki 20 e hiki mai ana. Ke kumukūʻai nei ka papahana holoʻokoʻa ma mua o $ 300MM mahele like i ka hapalua ma waena o Stage 1 a me Stage 2.
Wahi a ka Meia o Los Angeles ʻo Richard J. Riordan, “ʻO ke awa o Los Angeles kekahi o nā lei aliʻi o ko mākou Kulanakauhale, e hana ana i nā hana, e kākoʻo ana i ka hoʻokele waiwai kūloko, e hoʻopili nei iā mākou i ke koena o ka honua. I kēia lā, hoʻolauleʻa mākou i ka hoʻonui nui loa o ka mōʻaukala moana o US - a me nā mea hou e hoʻonui ai iā mākou i kahi kiʻekiʻe ʻoi loa. "
Brig. ʻO Gen. J. Richard Capka, ka luna koa, nā pūʻali koa o nā ʻenekini, ma ka ʻĀpana Pākīpika Hema, i ʻōlelo ʻia, "E hoʻomaikaʻi ʻia nā mea hoʻolālā mai nā awa ʻelua o Los Angeles a me nā Corps no ka hōʻoia ʻana i ka hoʻohālikelike kūpono no ke kūleʻa - ka hoʻokele waiwai, ka hana ʻenehana, a me ke kaiapuni - ua kaulike i kēia papahana. Haʻaheo mākou i kā mākou kuleana i ka hoʻomohala ʻana i kēia awa, ke hoʻi nei a hiki i ka hala ʻana o nā makahiki 1800 me ka hoʻokumu ʻia ʻana o ka ʻAilana ʻo Corps 'Los Angeles. Ke kakali nei mākou i ko mākou kenekulia ʻelua o ka lawelawe ʻana i ka poʻe o ka lāhui a me Kaleponi Hema. "
Ua hāʻawi ʻia nā ʻaelike ʻelua ʻo I a me II i ka The Pier 400 Constructors, kahi hui like o Great Lakes Dredge & Dock Co. a me Connolly-Pacific Co. Ua hāʻawi ʻia he $ 148.6 miliona aelike no ka pae I i Iune 1994. Aia ka papahana i ka hoʻomohala ʻana o 3 mi o nā kahawai hoʻokele ākea hou, kahi kahawai huli a me 5000 mau laina ft o ka berthing ma ka hema o Pier 300 ma Terminal Island.
ʻO ka lawe wai ʻana o 29 miliona yd3 o nā mea i hana ʻia e ka wai hohonu o 45 ft i 63 ft e hoʻokō i nā waihona hohonu hohonu a me nā moku pā maloʻo. Aia ka mea i kolohe ʻia ma hope o nā dikes rock, e hana ana i kahi ʻāpana he 265-acre (107.3 hectares) hou i kahi pae ʻāina hou i kapa ʻia ʻo Pier 400, aia ma ke kahawai o ka ʻaoʻao hema ma ka hema o Terminal Island. E pili ana kēia ʻona i kahi palena liʻiliʻi o ka hoʻopihapiha hou e hoʻopili ai iā Pier 400 i ka mokupuni ʻo Terminal kokoke i ke palena ʻo Los Angeles - Long Beach. Hāʻawi ka ʻāina hou i ka pale maluhia mai nā neʻe a me nā nalu.
Ua hoʻohana ʻo Lakes nui i kāna 36 ″ (914 mm) Eledott® hōʻailona pahu "Florida ” e hana i ka hapa nui o nā hana ma kēia hana. ʻO kaHawaii", Me 16,000 ka huina i hoʻonoho ʻia o HP (12,000 kW), ua hōʻike ʻia ʻo ia ka lua nui loa a me ka mana nui o ka ʻokiʻoki ʻokiʻoki ma United States. Ua hana ʻia a 138,000 yd3 / lā ma kēia hana i hiki ai iā Great Lakes ke hoʻopau i ʻekolu mau mahina ma mua o ka papa kuhikuhi.
Ke hoʻomau nei ʻo Stage II me kahiʻaelike he $ 150 miliona i hoʻolālā ʻia e hoʻopau ʻia ma Ianuali 2000. E hoʻomohala ka lua o ka hana o ka pāhana 63-ft channel i 81 ft, e hoʻolōʻihi i kahi keaka 50-ft a kūkulu i kahi kahawai 75-ft-hohonu i ka ʻaoʻao hikina o Pier 400, Stage I. ʻO ka 22 miliona yd3 o nā mea wīwī e hana hou i kahi 325-eka (131.5 hectares).
Ua hoʻokuʻu ʻia ka dredge uila i nā makahiki 1980 e hana ma ka wahi ʻo Los Angeles, kahi a ka Air Quality Control Board i kuhikuhi ai i ka mana uila o nā lako hana a pau. Ma hope o ka hoʻokomo ʻia ʻana o ka pauma alapiʻi ma ka ʻanuʻu 115 kapuaʻi lōʻihi i ke kaʻina o ka hohonu mua o nā kahawai, ua lawa ka mana o ka dredge 34-inch e pauma i nā wahi mamao e koi ʻia me ka ʻole o nā paipu booster. I loko o kēia papahana, e kīpē ʻo ia i 18,000 kapuaʻi mai ke kahawai komo i waho a hiki i ka piha. I ka wā o ke kūkulu ʻana i ke alahula halihali, ʻo ka laina hoʻokuʻu lōʻihi loa he 12,000 kapuaʻi. Me kahi 184-kapuai ka lōʻihi o ka moloā i hoʻomoe ʻia i ka hope, ʻo ka lōʻihi o ka lōʻihi o Florida he 450 kapuaʻi, e ʻae ana i kahi kowali ākea.
ʻO ka mea lawe moku ka mīkini maʻa ma kahi he 10,000 HP, 13,200 volt Canadian General Electric motor. Hiki mai ka mana o ke kahe ma ka pahu pahu ma o nā wāwae 15,000 o ke kaula kaumaha, i kau ʻia e nā pā lua.
Loaʻa ka motika Kanada mai ka noi mua a dredge. Ua kūkulu ʻo Ellicott® International i ka “Hawaii", A laila kapa ʻia ka"Clarence B. Randall", A me kahi kaikuahine like e dredge i 1953 no Caland Ore's Steep Rock Canada mine mine hao. Ua hana nā dredge ʻelua a puni ka uaki e kāpae i nā haneli miliona o cubic mau mika o ke kaumaha nui - ma kahi o hoʻokahi haneli mau mika ka hohonu. ʻO ka papahana Steep Rock ka mea e paʻa ana i kahi papahana mining dredge nui loa i hana ʻia. He makana ia i nā kūlana hoʻolālā hoʻolālā ʻo Ellicott® i ka lawelawe ʻia ʻana o nā mīkini kī ma kahi o 40 mau makahiki ma hope aku, a ke ʻae ʻia nei ke au o ka hull i nā hoʻomaikaʻi dredge aʻe i hōʻike ʻia ma luna.
I ka wā e hoʻomākaukau ana ʻo Great Lakes i ka “Hawaii"No nā papahana ʻo Pier 400 i ka makahiki 1997, ua hiki iā ia ke hilinaʻi iā Ellicott® International e hoʻolako i ka ʻikepili ʻenekini kumu piha, ma kahi o 40 mau makahiki ma hope o ke kūkulu ʻana, e kōkua i nā hoʻomaikaʻi ʻana o Great Lakes i ka lua.
Ua hoʻolālā ka Port i ka pūnaewele no ka ipu, ka nui wai a me nā pono kaʻaahi. Hāʻawi ka papahana ʻo Pier 400 i nā pono waiwai nui me ka hoʻonui ʻana o ka uku maoli mai $ 24.3 biliona a $ 40 biliona. Eia hou, e hoʻonui nā ʻauhau pekelala, mokuʻāina a me nā ʻauhau kūloko mai $ 12 biliona a i $ 19.8 biliona. ʻO ka papahana dredging a landfill ka pōhaku kihi o ka Polokalamu Hoʻokele 300/400 o Port, kahi papahana $ 650 miliona e hoʻopuni nei i nā papahana he 24. ʻO ia ka hoʻomaikaʻi nui ʻoi loa o kēlā me kēia awa o US a me ka papahana hoʻolālā kiʻekiʻe o ka Port i kāna mōʻaukala 90-makahiki.
Mālama ʻia ka papahana ʻo Pier 300/400 i kekahi o nā palena hema o ka Alameda Corridor, kahi kaʻaahi he 20 mile a me ke ala e halihali ai nā alanui, e hoʻopili ana i nā awa o Los Angeles a me Long Beach i ka pūnaewele rail intercontinental a hana i kahi ala wikiwiki a maikaʻi hoʻi. e hāʻawi i nā ukana ma ʻAmelika Hui Pū ʻIa. ʻO ke awa ʻo Los Angeles kekahi o nā awa kai ʻoi loa o ka honua a lawelawe ʻia ma ke ʻano he puka nui US West Coast no ke kālepa kūwaho. ʻO ka 7500 eka ʻeka he 30 mau pono nui ma nā mile he 28 ma mua o ke kai e loea i ka kaʻa, ka ʻāpana, ka pahu, nā pahu maloʻo a me nā hana ukana wai nui.
I ka hoʻomaopopo ʻana i ka mea nui o ke awa a hiki i Los Angeles, ua hoʻokumu ka Pūʻali Koa o nā ʻenekini - nā loea ʻenekinia o ke aupuni pekelala - i ka moku ʻo Los Angeles i 1898 e kōkua i ke kūkulu ʻana i kāna ʻōnaehana awa. I kēia lā, ma lalo o kēlā ʻuhane like o ke alu like a me ka hana lōʻihi lōʻihi, hoʻomau ka Corps e kōkua i ka Port me kāna loea ʻenehana, e hoʻolilo ana i ka Port of Los Angeles i hoʻokahi o nā awa kūʻai kālepa kalepa nui ʻo ʻAmelika.
