• Because of the placement of Royal Vistas on the leeward flank of Hualalai's "shield" <br />configuration, well-defined drainage features are lacking, as noted under the FLOOD <br />HAZARD section on p3-1 of the Grey Infrastructure Report in the Kona Community <br />Development Plan. <br />This will cause additional episodes of flooding and road wash -out as noted in the runoff <br />and pollution, harming coral reefs and damaging the ocean. <br />Horseshoe Bend and the Holualoa Stream an the parcels are listed in the second <br />paragraph of 3.1.1, (under the heading North Kona Flood Hazard Analysis,) as one of <br />the seven intermittent drainage ways studied by the North Kona Flood Plain <br />Management Study (1984) by the US Soil Conservation Service (presently Natural <br />Resources Conservation Service. (The developer has already diverted a portion of <br />these.) The Study proposed among the 6 non-structural and 4 structural alternatives for <br />flood zone management: <br />Non -Structural Measures: #2. Establish and maintain appropriate vegetative cover, #3 <br />Enforce county grading ordinance to reduce erosion and sedimentation. #4, Enforce <br />land use zoning to restrict future development within flood plain areas. #5 Initiate <br />state/county tax incentives for keeping flood plain areas in recreational and/or open <br />space use. <br />Structural <br />#1. Require all new developments to dispose of their runoff on site.#3. Improve road <br />culverts and bridges to carry larger discharge and provide additional ones where <br />needed. <br />Noting all of the details in the Study, one must be concerned at the potential for property <br />loss within the new development as a result of 1) removing huge amounts of vegetative <br />cover plus 2) eliminating much of the recharge by adding foundations and paving <br />driveways and roadways of a sufficient width to accommodate the inevitable roadside <br />parking and traffic passage. Uphill of the developed area is the Queen K/ Kuakini <br />intersection which could be impacted as well. . <br />Wild life <br />• Area is home to, and hunting grounds for, the endangered Pueo and Hoary Bats, <br />Hawaiian owls, the endangered and listed Blackburn's Sphinx Moth and many other <br />forms of valued permanent and migratory wildlife. <br />• Birds and animals do not limit their territory to human map lines. Conservation must be <br />considered on a regional, not individual parcel, basis. <br />• Only "native" plants are considered important in the developer plans, but all flora in the <br />
