Home

flow (approximately dated between 250 and 750 years before present) that fronts homes in HPP serves as a rugged walkway for the public to stroll along. Due to the unimproved county owned property one lot away from the subject property, ocean access is guaranteed and is currently used for fishing, walking,yoga and exercise. (These have all been observed by the petitioners/owners.) Public Access will be discussed in detail in Section L, Public Access. Some stormwater from the property setback drains onto the rock and into the ocean. Any additional stormwater will be managed effectively and without any impact upon neighboring properties, ocean or the existing infrastructure. (As was discussed in detail in Section E, Special Management Area.) The proposed single-family dwelling is not anticipated to impact the development of marine and coastal resources. There are no protected tidepools or other areas along the rocky shoreline that front the subject property. The proposed improvements to the property will not be built in such a way to impact any streams or channels that would disrupt coastal ecosystems. The property and proposed house are not anticipated to impact the development of marine and coastal resources given the 80-foot setback from the shoreline and the fact that the property sits 25 to 30 feet above sea level. No adverse impacts upon endangered species will occur as a result of the development. G. Surrounding zoning and land uses. The subject property is zoned as A-1a, as is all of HPP. The property is close to the dead end of Paradise Ala Kai Dr. On the other side of that road end, undeveloped property continues as zoned A-1 a. The surrounding land uses are residential or vacant property intended for development as residential. The flood zone as noted in the Section directly below is designated as "X," as shown in Exhibit G, which zones are defined as areas outside the mapped 500-year floodplain,with minimal risk of tsunami inundation. The proposed home site is located about 35 feet above sea level, about 90 feet back from the shoreline shelf,in an area that is clearly out of the flood zone. The proposed home site is located completely outside the area affected by high waves and tsunami inundation. Storm waves generated by Tropical Storm Iselle, which hit the Puna coastline on August 8, 2014, had minimal effect upon the shoreline here, and there were no effects to the proposed home site. Other than mega-tsunami of the type that would inundate all of Hilo and Honolulu, the home site is not at risk of tsunami. The very conservative siting of the home in this position at about 35 feet above sea level ensures that even with a sea level rise of five or more feet above its current level,the home will continue to remain well out of the effective flood zone.Even extremely large rises in sea level of the type that would essentially require the relocation of much of downtown Hilo and Honolulu would not affect the home in its proposed location. 1 Wolfe, E.W., and J.
