DEPARTMENT OF PUBLIC WORKS <br /> COUNTY OF HAWAII <br /> HILO HAWAII <br /> <br /> ~ecscona~cdcurc <br /> Date March 18, 1998 <br /> To RICHARD WURDEMAN, Corporation Counsel ' <br /> From DONNA FAY K. KIYOSAKI, Chief Engineer' <br /> i <br /> SUBJECT: YAGONG MEMO - RESOLUTION.NO. 225 ' <br /> Dedication Deed for Waiakea Heights Subdivision, Unit II <br /> Tmk: 2-4-37: 014 <br /> Our comments to Chairman Yagong's concerns are as follows: <br /> 1. Hawaii County Code, Chapter 23, section 23-30 Subdivision Control Code <br /> A. The subdivision is not traversed by a natural water course, drainage way, channel or stream. See <br /> attached definition from National Flood Insurance Program (FEMA) for AH zones. <br /> B. Not Applicable. <br /> C. In this particular case a ponding or possibly sheet flow area. See attached definition from <br /> National Flood Insurance Program (FEMA). <br /> 2. No. Subdivisions in an AH zone should pose no danger to the "health and safety of its occupants" <br /> when the requirements ofChapter 27, Flood Control, are followed. We do not believe section 23-37 <br /> is applicable to this or any other subdivision within any mapped flood zone. Instead the Department <br /> has been following the provisions ofChapter 27. Sections 23-30 and 37 were crafted in 1975 as part <br /> of our first comprehensive subdivision ordinance. Its intent was to identify, disclose and to prevent <br /> construction in flood areas at a time when we had no FEMA flood maps, no flood classification <br /> system or appropriate flood design and construction standards. There are still no established <br /> guidelines, policies, procedures or standards to even identify "periodic inundation" areas. Chapter <br /> 27 addresses all of the shortcomings of 23-30 and 23-37 by following the requirements of National <br /> Flood Insurance Program. The subdivision sections are technologically outdated, too conservative <br /> and arbitrary when compared with the provisions of Chapter 27. Chapter 27 is also far more <br /> comprehensive as it is applicable to all new residential construction. The Department does continue <br /> to use the provisions of Section 23-30 and 37 where an unmapped gulch exists in order to give a <br /> developer an alternative to conducting a costly Chapter 27 flood study. <br /> ~o. ~ q 02 <br /> ~ r, Doc. v <br /> 'resented P u/Pc <br /> E:\WP FilesUM1EMOSUNTER.WPD(50) 'rp~-' - <br /> ode .17AY 5.1A9w ~ <br /> <br />
