H. Flood Insurance Rate Map (FIRM) designation (contact Department of Public Works-Engineering Division). Due to setback requirements, all of the proposed development is designated as Flood Hazard Zone X: "Areas determined to be outside the .02% annual chance floodplain"according to the U.S.G.S. As shown in Exhibit G The proposed home is more than 80 feet from the high water mark per the Certified Shoreline Survey and as shown in Exhibit H, Blended Site Map the proposed residence sits well back from the shoreline. L Archaeological Resources: The Planning Department will assist in the assessment of archaeological resources in cooperation with the State of Hawaii Department of Land and Natural Resources Historic Preservation Division (DLNR-SHPD). To assist with this assessment, Petitioner provides the following historic information: Description of Property The property is located at approximately 30 feet (9 meters) above mean sea level at its lowest point on a single Kilauea lava flow dated between 250 and 750 years before present.2 The geological substrate is bare pahoehoe lava as provided on the Wolfe and Morris geological map (see Exhibit I) with very shallow soil deposits.3 The property ground surface is mostly level, sometimes undulating with a slight easterly slope makai (toward the ocean). Annual rainfall at the property ranges from 120 to 160 inches. There are no major gulches or natural drainages located near the project area. The surveyed property is 80 feet wide at both ends east and west, with the northern side of the property nearly 209 feet in length and the southern side nearly 257 feet in length. The different lengths are the result of the uneven cliff drop-off at the shoreline. The cliff drop-off is approximately 30 feet from sea level. The property borders Paradise Ala Kai Drive on the mauka or west side of the property. The shoreline area of 40 feet is made up almost entirely of bare pahoehoe lava bordered toward the proposed home by some ironwood trees. The additional setback of 40 feet has some shrubs, palms and ironwood trees. (See Exhibits J through M for photos of the property.) Previous Archaeological Studies Both pre-Contact era and post-Contact era habitation and land-use are known to have occurred along the Puna coast. The majority of studies conducted in Waikahekahe Nui and surrounding ahupua'a were conducted along the coast. Coastal archaeological sites consist primarily of habitation features, agricultural features and trails. Habitation features are primarily enclosures, platforms, rock paved area, and terraces. Agricultural features include rock clearing mounds and small garden enclosures. None of these features have been discovered on the subject property during extensive walk-throughs. 2 As noted supra,Wolfe and Morris s Sato, H.,W.
