Th soil rconnaissanc consistd of a rviw of slctd sqil and gologic maps and visual obsrvations at th sit. FIELD OBSERVATIONS Th proposd sit is locatd on th. wst (Wahiawa) sid of Waimano Hom Road about 1,000 to 2,000 ft north of th intrsction of Waimano Hom Road and Komo Mai Driv. Th sit gjlrally slops down. i,n ;;t wstrly dirction from Waimano Hom Road at about 3 to 1 or 4 to 1 gradints for about th first lo.to 40 ft, thn at about 2 to 1 slops with. stpr localizd variations. From visual obsrvations, most of th sloping grounds ar covrd with shrubs. Th xposd soils at th top of t;h slops may. b gnrally approximatd as surfac layrs of silty clays ovr d<;ornposd rocks ar).d/ or bouldrs. Som rocks or dcomposd rock outcrops wr notd about 75 to 100 ft blow th lvl of Waimano Hom Road. Soin loos bouldrs, cobbls, rocks and dcomposd rocks wr also notd along t;:h tos of slops..,,

Q'I'H:ERS Gologic Dscription :Sy Qt:::tu~rs According to th Gologic Map of Oahu by Starns, th slops and tops of slops ar mappd as Koolau basalts, (Tkb); th northrn floor of. th ridg as consolidatd dpos:its, chifly oldr alluvium (Qa). Soil Dscription By Othrs According t.o th U. S. Soil Consrvation Srvic (1972), th surfac soils ar mappd as follows: North.rn. :Floor of Ridg Kawaihapai stony cla:y loam (KlaB: 2.to 6% slop) Mo4+at shrink-swll potntial; stony ill. placs. Slogi'J.

4 PARK ENGINEERING, INC., Jun 18, :1,973 3 In our opinion, singl-fat'!lily rsidncs can b dsignd for slctd... aras on th sit. Th following discussion and guidlip.s should b.. considrd for dvlopmnt studis: 1. Bcaus th sit is situatd mostly ovr sloping grout1,d, no gradip.g or lllinimtim grading on th lots sho1.1ld b.. considrd. Fill should b avoidd, if practicabl.j. 2.. Post and 'b~ typ foundations ar rcommndd for th. rsidncs, garags and port:j,o~s of drivways that. xtnd ovr slops. 3. Structurs 'should b dsignd to t;olrat and rsist som sttlmnts and as small units on platforms or. dcks rsting on post and bams that would allow floors to b r-lvld should sttl~nts occur. Odd-shapd and split-lv1 structurs should b minimizd or dsignd to float as a unit. 4. To minimiz th. ffcts of slop crp, th foot blocks should b supportd on short pip pils that xtnd blow an stimatd crp zon. Th pip pils should b about 10 ft or mor in. dpth. Th foot blocks should 'b tid up and down th slop. J 5. Rtaining walls should b avoidd or kpt to a minimuiil whrv~ practicabl. ',. 6. Good surfac drainag away from th foundation of structu_ts should b maintaind an:d th sit gradd. to prvnt pondirig of watr. :,,." 7. Th bottom of ut-ility trnchs should b daylightd and gradd to shd. watr.. Th backfill and drai.jlag of utility tr~nchs should b carfully dsignd/. Flxibl connctions should b usd. Although not notd during th soil rconnai;.ssanc, unforsn conditions such as soft spots, "CH'' clay pockts, and spag watr may xist in local.izd aras. Planning should b kpt flxibl and adjustmnts may hav to b mad ip._ ths aras.
