It's also not feasible for, especially these full time farmers and ranchers, to install flood <br /> control structures designed to handle water from a 100-year storm. Many of these <br /> structures will consume valuable land to grow their commodities and/or be too expensive <br /> to install. A case study is attached. This issue may lead to who will pay to re-design and <br /> re-build existing structures that do not meet the 100-year event criteria? <br /> Currently we follow MRCS guidelines for planning. We design practices such as <br /> diversions, ten•aces, and grassed waterways for farms to protect ~7opland to handle water <br /> from a 10-year storm event. Any request for a pzactice to be planned fora 100 year <br /> storm event is forwazded to the U. S. Army Coxps of Engineers. This type of planning is <br /> related to large sized flood control projects protecting neighborhoods or towns. <br /> In conclusion, it appears the motive of the proposal is driven by problems occurring in a <br /> specific region of the island There needs to be additional professional engineering <br /> studies and flood mapping to target flood prone areas around the entire Big Island. The <br /> council should reconsider the proposed changes and after detailed flood studies had been <br /> done, `Yed flag" certain areas around the island to follow more reasonable rules and <br /> regulations. <br /> Respeetfullly Submitted, <br /> nda Iokepa Mose Chairperson, Ka'u Soil & Water Conservation District <br /> <br /> Jus ' ]?en• , S 1 onservationist, East Hawaii Soil and Water Conservation Districts <br /> <br />
