4. Ar·ea No. 2 - Soil. Types 1-c and 1-f

Most of this area was filled 6 or 7 years ago with 8 to

12 feet of stiff clay mixed with gravel, boulders and some

trash.· This material overlies compressible.clay.which

can .. result in foundation failures unless. the: foundation

loads are low.. The upper 3 feet of fill :will need to be

excavated and the boulders and deleterious.material·removed

from the. site. The upper.3 feet can be replaced with on-site

granular material compacted to 90% (AASHO-T-180-57) _.

5. Area No. 3. - Soil Types 1-d and 1-f

This area was filled. recently_ with clayey gravel-and overties

compressible clay .which can cause foundation failures, unless

the foundation loads are low.. The upper 2. feet- of £ill,

should be removed. and recomp~cted to 90% (AASHO-T-180-57).

6. .Area No. 4 - Soil Types 1-e and hf

This area has .been recently dredged and. partially refilled ,

with gravelly clay a_nd boul(lers. The upper 2 feet of fill

7. Water was encountered in some of the test pits,. generally

2 to 4 feet below the lake elevation. At the time of this

exploration" the water level was· lowered, by pumping for the

construction of the sewer line. along. the ex.tension of Keolu

Drive. It is anticipated that the ~ater level will readjust.

to the approximat~ lake level after pumping is.stopped.

'. SITE DESCRIPTION

The ~rea covered by this investigation consists of.approximately

14 acres located in the Enchanted Lake~ area .. in Kailua, Oahu,

Hawaii. The area is bounded on. the north bya rock ridge and

an abandoned rock quarry,. on the east .by Enchanted Lake Estate

Un~t 8-:B-:1, o.n the south by Enchanted Lake.and on the west by

Kaopo·Subdivision, Unit 2.

The proposed extension of Keolu Drive cuts across·the site.from.·

northeast to southwest and .divides the area into nearly two .

equal parts. At the time of this investigation,· a ·sewer .. line

.. was being constructed in a 15 to· 20 -:foot deep trench alon-g the

Keolu Drive right away. Exposures along this sewer trench

provided verification.of .subsurface soil conditions exposed in . . . . · .. :

·the.· test pits. Hard· lava rock .si~ilar. to that exposed in the.·

abandoned quarry was .noted along the east· section of the french.

Lake mud and underlying finger corai was .noted along the west

portion. There appeared to be a transition from hard lava to

softer, weathered basalt with some coral and mud deposits in·

the center section. All these formations are covered.with

_varying thicknesses of fill material consisting of boulders,

clay and gravel.

Except for the rock exposures on the north edge of the site,

two-thirds.of the area is covered with fill material which,

· we understand, was placed at various times over a period of

six or seven years. The remaining third along the west edge

of the site is covered with stockpiles of clayey gravel and

finger coral. recently dredged £rom the adjacent pond and,

. :-·

mar~h area.-

The site slopes gently from north to south. from app.roximate.

. elev'ation 20 at the base of rock slope to elevation 6 near

the iake. shore. The surface. is fa~rly smooth where .the older

fill has been placed. and irregular where the ·recent. sto.cl<piles . ·

are located.

FIELD EXPLORATION

Sixteen (16) test pits south and four (4) test pits north

of Keolu Drive extension were dug with a one cubic yard.

. ba~hoe to depths of 6 to 20 feet. Undisturbed samples were ,

obtained using a drive tube sample spoon with. a 2.8 inch I.D.

Also representa.tive samples were obtained during the field

exploration for laboratory tests. The soil material encountered

in the test pits and that· exposed in the sewer trench does not . _

necessarily represent subsurface conditions at.other p~ints on

the site; however, sampling proceclures are believed to be

representative! The soil material was classified visu~lly in

the field and representative undisturbecl and disturbed samples

were returned to the laboratory for a more detailed analyses.

LAI~ORATORY TESTS

Representative samples were analyzed in the.laboratory to

determine. classification of the .material in accordance with

the Unified Soil Classification System.· Consolidation tests,· ..

unit weight, moisture content, and laboratory maximum density.

and C.B.R. tests we.re performed on the soil material derived

from the site.

The material was too soft to run direct shear and unconfined

compression tests so the compressibility propetties·w~re

- determined from the consolidation tests.

Moisture content was determined for most of the·sa,mples. The

~stiff, clayey fill, soil type l•c, ·averaged 40% to 50%, while

the underlying co~pres~ible clay, soii type 1-f, ran from 70%

to 100%.

Atterberg Limit Tests were performed _which indicated the soft, . .

·clayey soils generally fall into t:he OH-MH soil classification.

Hydrometer Analysis Tests were performed to determine the, per­

centage of sa:nd, silt· and clay. Many. of these tests indicated .·

a very high content of clay., The soils were not critical with

respect to expansidn propettjes .. Test results indicated less

than 3 percent expansion.

Laboratory test results ate· presented .. in. summary form in the

appropriate spaces on the drilling logs and in the appendices i

which are included.with this report. A discussion.of th~·field .

. and laboratory tests and the recommendations· as derived there.,.·

DISCUSSION.

The results of field observations, pit excavations and labora-

tory tests indicate six general soil types exist at. the subject .

site. The site bas been divided into.four areas based upon

anticipated foundation conditions~ See Figure 1 fot locatiOn.

Area 1 - This area lies along the north side of the site.

Hard lava rock is exposed in theridge.that rises over 100 feet

above the gen~ral area. The rock is exposed in a series of cut

slopes and benches left· from an abandoned rock quarry. · The

propOsed 1:1 slopes with 10 to 30 feet wide benches are satis~

factory as shown in Section A on grading plan dated March 19, 1970

prepared for this project.

Rocky fill composed mostly of angular quarry.rock and talus

lies along the base of the rock slopes and extends out 150 to·

400 feet on an east.,.west line that crosses Keolu Drive Extension.

See Figure 1 for approximate. limits of Area 1.. . It •· is. recom:m:encled

that the large boulders and otherdeletetious.materials be

removed and the upper two feet be.recompacted withon:.site granular

material to 90% (AASHO-T-180-57)•

Stiff, clayey fill mixed with_ gravel and boulders together

··. with some grass, wood, concrete blocks, wire rope 'an4 cans

was encountered ih Area Z (See Figure 1). This fill was put

ifi about 6 or 7 years ago and averages 8 to 12 feet thick.

Underlying this fill is a 6 to 8-foot layer of soft.to

medium compressible clay mixed wi t.h some· peat. · Consolidation

tests on .this material indicate medium to high compressibility.·

It is recommended that ~he upper.3 feet of fill in Area 2

be excavated and all boulders and.deleterious.material be

removed ... The upper 3. feet can be replaced. with on.-si te

•. granular .material compacted to 90%. (AASHO-T-180-57). It is­

also recommended that foundations be designed for 800 P.S.F.

Area 3 - This is a smallarea along the south center portion

of the site rtext to the 1ake. This area was.recently filled

with approxima1:~1y 10 feet of clayey gravel, the upper 2 to)

4 feet of which is in a 1·oose condition. This materiaL is .

also underlain wi t.h the soft clay layer described for Area 2.

It is recommended that the upper 4 feet of loose gravel and

clay be excavated and the deleterious material be removed. ·. ' ' . ,

The gravel· can then be compacted to 90% (AASHO-T-180-57) •

Area 4 - This area is located alol1g the west-edge o:f the

site. This area has been recently dredged and partially

refilled in the vicinity of Test ~it Nos~ 10, ll,and 12

with gravelly clay ahd boulders. The ternai,nihg portion

consisted of ir:regt1la:r stockpiles of :recent~y dredged la_ke

mud, coral fragments .and cobbles.

The uppe,r 2 feet o.f .fill and the stockpiles will need to

be excavated and the pou1ders and deleterious material r¢moved.

from the si.te. . The upper 2 :f~et: .· c~n, be- replaced with on-site
