REPORT MAKARA VALLEY, WAANAE, OAHU, HAWA SCOPE OF EXPLORA''ON Th purpos of this xplorationwas to valuat gnral so;i.l conditions for foundationdsign considrations for th proposd Makaha Drainag Channl at Makaha Vally, Waiana, Oahu,.Hawaii. This rport includs fild xploration, laboratory tsts, gnral rcommndations for foundation dsign cbnsidrations and limitations. FELJ) EXPLORATON AND LABORATORY l'ests Svn opn pits wr mad at th sit. Th approximat locations of th pits ar shown on th Opn Pit Location Sktch. Soil sampls wr rcovrd from th opn pits. Laboratory tsts includd: natural watr contnt, laboratory van shar, Attrbrg limit and grainsiz analysis. A summary of th laboratory tst rsults is givn in Tabls A thru C.

5 SOL CLASSFCATON SYSTEM Soil sampls wr visually obsrvd and subjctd to appropriat tsts in th laboratory. Basd on visual obsrvations and laboratory tsts,. th soi_l dsctiptiotu; givn on th b(>ti.ng logs ar gnrally mad in accordanc with th "Unifid Soil Classification Systm." GENERAL STE CONDTONS Th sit is locatd north of Kana Drivabout a half mil ast of Makaha Bach Park. A drainag channl is proposd around th ast and north sids of an x_ist;i,.ng wast stabiliza.tion pond. with localizd dips and mounds Th ground lvation$ vary from about Th sit gnrally slops upwar4 towad th north at about 1% gradint 1.5 to 2 ft along th xisting stram nxt to th wast stabilization pond to al;>out 4 ft along th northrn primtr of th proposd limit of fill. Th proposd alignmnt crosss irrgular tolling trrain. Existing ditchs and stockpils of bouldrs, arth and tr stumps ar scattrci in localizd aras. _, :,\.,_,. {, ::'2

6 An unpavd accss road runs along th north sid of th xisting stram. Th stram was dry during th fild xplorations. A lind pit (old dug wll?) abot1t 3 by 35ft inplan and about 2 to 25 ft in dpth was notd at th wstrn nd of th sit. Watr was notd in th pit about 22 ft from th ground surfac. An oi_l tank was also notd nar th pit. Somrmnants of old concrt foundations wr J{posd along th north portions of th s.it. At prsnt, th ground is ovrgrown with grass, shrubs and. trs. A papaya fild was nar th wst sid of th sit. NTERPRE''ATON OF SOL CONDTONS FroD1 th opn pits. and laboratory tst rsults; th _soils may b approximatd as. follows: Alluvial_ dposits of ich" clays with bouldrs and siltysandy dposits mixd with bouldrs to about 7 to 15 ft, th dpths of th tst pits. Watr was not notd in th opn pits during th fild x];>lorations. 3

7 Variations to th abov soil C:onditions ar to b xpctd btwn opn pits and in localizd aras..for mor dtaild dscriptio]ls of soils ncountrd in th opn pits, rfr to th opn pit logs. DSCUSS:LQtij' AND RECOMMENDATONS Th proposd plan i.s to align a portion of th north braqch of Makaha Stram around th ast and north sids of an xisting wast stabilization pond. A channl about 1,3 ft in lngtl) and about 2 ft wid (bottom of channl) at th strn nd and about 15 ft wid at th wstrn nd is proposd. Th south or lft.bank of th channl (along th wast stabilization pond) would b formd by a brm about 15 to 2 ft in hight. About 15 ft. width is proposd across th top of th brm. Th north or right bank of th channl would b about 15 ft high. Th bank will b formd niostly by brms. Som cuts up to about 1 ft in hight will b involvd. Th cuts would b toppd or cappd with fills to form th 15ft high channl wall. Channl Slop Bcaus of th clayy surfac soils ncountrd in som of.th tst pits, flat slops ar gnrally prfrrd. 4. ; '

8 n gnral, 2 horizontal to 1 vrtical or flattr slops should b considrd for th channl sid slqps, providd th outr portion of th slops ar consq::uctd with slctd silty,. sandy or fairly wllgradd granular matrials. Whr clay "CH" soils at xposd in cut slops, th, clays from th outr portions of th slops sh()uld b rmovd and th slops rconstructd with slctd matrials. To minimiz rosion of th chat:tnl banks that would b xposd to th flow of storm watr, som form of slop protction is rcommndd. f a bouldr.riprap lining is considrd, a filtr layr is rcommndd btwn th bouldr riprap and th.natural ground..... ot fill matrial to minimiz migration of fins through th bouldr linin.g. For th slops not xposd to storm watr flow, slop planting is rcommndd. Howvr, th construction of th outr portions' of th slops should b mad with matr.ial othr than "CH" clays. Slops of 2:1 or flattr should b considrd. 5

9 Us of rock fills along th tos of slops of th channl banks may also minimiz rosion. Howvr, s.om maintnanc work may b rquird, particularly ovr clayy soils. Sit Grading Guidlins Gradiiig work should b don as rquird by th Rvisd Ordinancs of Honolulu, 1969 As Amndd, and as rcommndd blow: L Th ara should b clar.d and grubbd. Surfac vgtation and misc;llanous dbris should b clard and rmovd prior to sit filling. 2. Stockpils and localizd soft pockts sho.uld b strippd tost.iff natural ground bfor th placmnt of fills. 3. Th bottoms and sids of ditchs should b.strippd to stiff natural ground. 4. Th matrial xcavatd and fr of dlttious mattr should b. stockpild for mbankmnt fill matrials. Th clayy (CH) soils should b usd for th cntral (cor) portion of th.mbankmnt. Th siltysandy and gravlly matrials should b usd to construct th outr portions of th slops. Th cobbls and bouldrs may b usd for riprap (s Figur 1). 6

10 Th matrial usd to build th cor should b gnrally lssthanabout 6in. maximum siz with about 4% fins. Th soils btwn th bouldr riprap and th cor may b wi.th slct on$it fairly wllgradd granular soils gnrally lss than about 6in. maximum si z with a plasticity indx lss than 2. Som of th slct ma.trial.may hav to b importd. 5. Fills should b constructd in approximatly lvl layrs starting at th lowr nd and working upward. Whr fills ar mad on slop.fng aras stpr than 5 horizontal to 1 vrtical, th ground at th to of th fill should b bnchd to a gnrally lvl condition. As th fill is brought up, it should continually b kyd into th stiff natural ground by cutting stps into th slops and compacting th fill into ths stps. 7 ;_

11 6. n gnral, fills should b laid in 6in compactd layrs to about 9% of th mlmt1d dnsity dtrmind by th AASHO T18731 tst mthod. 7. Provisions to drain th sit should b includd during and afr th compltion of.filling oprations. Backfill of Abandond Dug Wll Th old dug wll should b vrifid with th Board of Watr Supply and th backfill don undr thir guidanc. Th location and dpth of an qndrground tunnl or shaft (if any) should b chckd out. Bac:kfi:J,ling may b considrd to miriim;iz th occurrnc of a collaps, particularly ovr th fill aras. Unforsn Conditions Bcaus of th variability of soil dposits, sit improvmnts, dsign:arid construction tchniqus, conditions may b ncou11trd that cannot b,.forsn with vn th most xhaustiv. studis of sit and projct conditions. Ths unforsn conditions should b rcognizd whn ncountrd and thn val'ua.td so that thl;! dsigns or th construction mthods may b mo.difid accordingly, if ncssary.., 8
