1 Because of the urban nature of this area, there is no classification listed in the Land Study Bureau Overall Master Productivity Rating document. However, areas proximate to the site were designated Class "C" or Fair. This suggests that the site does have reasonable productivity potential for agricultural crops. It is of the Olaa Soil Series, with moderately deep and fine soil. The parent material is volcanic ash; is well drained but moist; and poorly suited for machine tillability. It should be noted that the adjoining sites that were classified C-180 and C- 178 have since been developed into single-family residential house lots. The State of Hawaii's Awicultural Lands Of Importance to the State of Hawaii (ALISH) maps does not classify this site as being either "prime, unique, or other" agricultural land. C. Natural Hazards 1. Drainaze The US Corps of Engineers' Flood Insurance Rate Man (FIRM) designates the project site to be located in Zone X, areas outside the 500-year flood plain. As such, the site does not appear to have any development constraints relative to drainage and/or floodwaters. 2. Tsunami Hazard As the site is located over 3 miles from the ocean, it is located outside of the Civil Defense's Tsunami Evacuation Zone. 3. Volcanic and Earthquake Hazards The United States Geological Survey (USGS) classifies the area as Lava Flow Hazard Zone 3, on a scale of ascending risk 9 to 1. This is the same classification as the entire City of Hilo. There is very little that can be done to mitigate this situation and reflects an ongoing threat to all residents and businesses in these areas. The entire island of Hawaii falls within Earthquake Zone 3, according to the County Building Code. As such, certain structural requirements will be needed and taken during the building permit process to address this seismic hazard. 4
