Dear Chairpersons Hoffman, Ford and Members of the Hawaii County Council: t; ,,t

We would like to indicate agreement with the comments in Director of Public Works, Bruce
T,.a~,:,,~,..
McClure's letter to the Honorable Brenda Ford dated March 22, 2007, and would also like to
amplify the following:
Item (6), Page 17: While a civil engineer can determine flood elevations and
flooding effects based on rain events of pre-determined probability, a civil
engineer cannot certify the "likelihood of flooding" because the likelihood of
t3ooding is determined by future probabiliiy.
Item (d) (1), Page 20: Requiring that certain Federal and State Permits,
including the 404, 401 and NPDES permits be provided at the time of
subdivision application would require that the applicant submit subdivision
plans to these Federal and State agencies prior to obtaining any form of
subdivision acknowledgement from the County. We feel that such action
would undermine the responsibility of the Planning Department for
development, because the County would be the last agency (rather than the
first agency) to have knowledge of a planned development.
Item (e), Page 20: We believe that changing the drainage requirement from a
10-year storm to a 100-year storm would create excessive over-design for

both private and governmental entities; the basis of selecting the original 10-
year design storm was an economic decision, where the damage from a storm
in excess of I U-years would be weighed against the cost of over-designing
infrastructure. Furthermore, the "Storm Drainage Standards'" only provides
Plate 6 as a guide for application of a I UU-year storm event for areas more
than 100 acres; the implication is that the "Storm Drainage Standards" shou)d
be updated if a 100-year design storm is implemented for all infrastructure.
Should you have any questions, please contact me at (808) 52I -5361.
Very truly yours,
