Re: Proposed Ka'awaloa Orchards Agricultural Project District
Dear Sally, June 3, 1997
Regarding the concerns about the roadway for the proposed Ka'awaloa
Orchards Agricultural Project District crossing portions of Lots 4B
through 76, the following is being proposed:
1) The existing road (previously designed by me) between lots 4B
and 5B will remain in its present form.
2) A similar standard will be continued between lots 66 and 76,
1 6 feet of pavement in a 20 foot graded right of way.
3) The road will be engineered for and posted at a 1 5 mph speed.
The impacts of this proposal are significantly less than that of a County
Standard Road, which the County could impose and for which Easements Al
and A5, as shown on the attached subdivision map (exhibit "B") have been
specifically reserved. I understand that further cut slope fill easements
have been reserved over 66 and 76.
I have prepared a sketch (exhibit "A") of typical cross sections of both the
proposed road and the County Standard Road for comparative purposes.
I also include a preliminary sketch of the cut and fill necessary for the
proposed extension of the existing road engineered for 1 5 MPH. The cut
and fill for a County standard road would be much more extensive both
because of the greater width and because it would have to be engineered
fora 25 MPH speed which would require a substantially greater degree of
grading. ~ 2, 02-

Regarding the suggestion of speed bumps, I am unwilling to include these
on my drawings for liability reasons. I do not believe that the Department
of Public Works will accept them and I point out that the same risk of
liability could extend to the lot holders on which such speed bumps might
be located. They are not a practical alternative.
Speed will be naturally reduced by the narrower 15 MPH design of the
proposed road. Speed can be further reduced by extensive use of signs
such as Private Road, Children at Play, and 15 MPH. I am willing to
include these in my drawings. If the 1 5 MPH design speed is accepted,
I will have some flexibility to design a road which encourages caution
while maintaining sound engineering practices.
Please be assured that I will be personally supervising the implementation
of my work. This will include the eventual layout in the field, and
consultation with the lot holders regarding the mitigation of any
construction impacts. Should you or any of the lot holders have any
further questions, please do not hesitate to contact me directly.
Yours incerely,
eo Flemm'`g P.~-'
