V1. ENVIRONMENTAL CONSIDERATIONS A. General Description The subject parcel is located on the northeast corner of Kaloko Drive and Hao Street in the Kaloko Mauka Subdivision. It is nearly seven (7)miles from the shoreline at approximately the 2,500-foot elevation. The parcel is gently sloping in a westerly/easterly direction. The mean annual rainfall in this area ranges between 50 and 70 inches. The wetter months tend to occur between June through September. The mean annual temperature is about seventy-five (75) degrees Fahrenheit, with the warmer months during the summer. Because the site is situated on the leeward side of the island, winds tend to be light and variable. Slight easterly winds occur during the day, while westerly or mountain winds are prevalent during the evenings. The site is vacant of anv structures. B. Soils and Topozraphy The topography of the site slopes slightly at about an average grade of eight (8) percent in a westerly to easterly direction. The Land Study Bureau's Detailed Land Use Classification System identifies the soils as"E" or"Very Poor" for agricultural productivity. The USDA Soil Survey Report identifies the soils on the property as of the Kiloa Extremely Stony Muck (rKXD), which consists of well drained, thin extremely stony organic soils over fragmental A'a lava and used primarily for woodland and pasture. The State of Hawaii's Agricultural Lands of Importance to the State of Hawai'i (ALISH)maps classify this site as being "Other Agricultural Land". C. Natural Hazards 1. Drainage The Federal Emergency Management Agency's Flood Insurance Rate Map (FIRM) designates the area of the proposed development to be in Zone X (areas outside of 500-year flood). As there will be added level of impervious surface resulting from the new road serving the subdivision, drywells to contain surface or project generated water may be needed. Aside from the potential drywell(s), no additional drainage improvements are being contemplated_ 14
