Subject: Final Grading Report
Gentlemen:
lhona (Parcel "b") Gentry-Waipio Development Waipio, Oahu; l-:lawaii
At your request, we have provided testing and observation services for the Ihona project of the Gentry-Waipio Development. The major portion of the earthwork was completed by May 5, 1983, while grading of the roadways was completed by August 22, 1983 after the utilities were installed. This letter summarizes our .observations and test results. Our scope-of-work did not include monitoring the subsequent construction of the dwellings and related items.
Prior to the start of actual grading operations, the site was cleared and stripped of the surface vegetation, rubble and other deleterious materials. The natural ground was then rolled with Caterpillar 815 and Raygo Ram 75 compactors. Soft spots, uncompacted fills and stockpiles of construction debris were removed.
Fill material was generated from excess material excavated from the adjacent Laulea, Nohea, and Neighborhood Park projects at the Gentry-Waipio Development shown in Figure 1. The fill was a low to moderate plasticity silt (ML), and was placed and compacted in relatively uniform lifts of 8 inches in thickness, at moisture contents generally within 3% of the optimum as determined by laboratory compaction test, ASTM 01557.
Field density tests per formed by our firm indicate that adequate compaction was being Obtained. These tests, upon which acceptance is based, showed values in excess of 90% relative compaction as determined by the above-referenced test. Additionally, density tests taken in the upper 24 inches of the roadway and parking areas indicate relative compaction of 95% or more.
Building Pads A through H and J through L have been graded to final grade elevations as designated by the field grade stakes and compacted to 90% relative compaction. Roadways A through D and related parking areas have similarly been graded and compacted to 95% relative paction within 24 inches of final subgrade.

In summary, earthwork of the lhona Project has been completed in general accordance with the Grading Ordinance of the City and County of Honolulu and the recommendations of our Subsurface Investigation Report dated August 16, 1982, and are ready to receive further improvements. Building pads should not be allowed to dry excessively and slopes should be grassed as soon as practical.
A Site Plan, Figure 2, is included to indlcate the field density test locations. The results of the laboratory and field tests performed by our firm are summarized in Tables I and II and graphically exhibited in Figures 3 through 6.
Should you have any questions concerning this matter, please do not hesitate to contact us at your convenience.

. ' ' .· SOIL AND GENiRAL SITE CONDITIONS:
' ~. ·. . . '
~ . ;
·The· borrow site ·is ·.on abandoned agricultural land, overgrown - ~~with grass and shrubs, and sloping gently riorthward with ele
vations ranging from 425 feet to 440 feet above sea level.
EROSION HAZARD:·
·The erosion hazard is slight.due to the small area to be graded {3.0 acres), the low rainfall index (250) and the.heavy vegetation covering the land. ·
CONSTRUCTION SCHEDULE: ., ·. '
Note: Both Areas A and B wi11 be ~raded concurrently. ,, I •. • • ' •
i. Clear and grub and ~rade sediment basin at the downstream· end of both Areas_ "A" and "B" {June 14 - July_ 9~ 1982)
. . .
2. Commence botrow site grading, begirini~g from the sediment basin and working upstream to the 1 imi ts of the borrow· site {July 9 ~December 1, 1982)
3. Grass all e~~osed areas {December 1-17, 1982)

SEVERITY RATING CALCULATIONS:
1. Project Conditions
The 6.0~acre borrow site is separ~ted into two area~: Area A (3.0 acres) and Area B (3.0 acres). Both areas consist of soils classified as Molokai silty clay loam, 3 to 7 percent {MuB). ·
Grading win· b'e during· the summer and winter months over a six~~onth p~riod, and the entire graded area will be. grassed immediately after grading~_
2. Values of Equation Factors
Note: Area A and Area and graded condition. equal for both areas. Area A.
B are separate but similar in area Therefore~ tbe severity rating is The following calculations are fo~
F - 2 (Table 1 ~ Damaged area more than 300 feet from site,' no stream o~ channel from site to dama~~d areal
