A. Location Iki Place is located west of Mamalahoa Highway and south of Hualalai Vista Subdivision, within the ahupua'a of Kohanaiki, North Kona District, island and County of Hawaii ("Project Area")(see Exhibit A). The subdivision was approved in 1962 and currently consists of 18 lots ranging from 7,632 sq. ft.to 10,089 sq. ft. The current county zoning over the entire subdivision including the roadway is A-3a(Agriculture, 3 acre lot size minimum). There are I5 lots with an existing dwelling and an active account for water service. The subdivision was created prior to the enactment of the County Subdivision Code requiring water system improvements. Therefore, each lot obtained water service from the DWS water system from meters located at the intersection of Mamalahoa Highway and Hale Pule Road (also known as "Church of God Road"), approximately 700 1.f. mauka from Iki Place. B. Purpose and Need Each of the 15 lots within the Project Area has an existing service from the existing DWS water system on Mamalahoa Highway above the subdivision through its own individual water meter. These lots rely on customer water lines that traverse along Hale Pule Road and along Iki Place. As these meters do not front the lots, they are considered "Out of Bounds" where the customer is responsible for maintaining their water line fronting and/or traversing neighboring properties. Furthermore, there are currently no fire hydrants located along Iki Place. 2. Character and Extent of Proposed Improvements As the lots are "non-conforming" to the existing county zoning,the requirements of the water improvements will be based on use and land area size, which is similar to county RS-7,5 zoning (Residential Single, 7,500 s.f. minimum lot size). The Project will he installed entirely within the existing private roadway, Iki Place and along portion of Aniani Street. The proposed water system improvements would service 18 lots within the Project Area (see Exhibit B). An easement will be required over the private roadway for maintenance and operation of the water system improvements, which will need to be dedicated to the Water Board of the County of Hawaii. In order to meet current DWS Standards for the RS-7,5 zoning, installation shall include(See Exhibit C): a. water mains capable of delivering water at adequate pressure and volume under peak-flow and fire-flow conditions; minimum diameter of mains shall be 8-inches from an existing 8-inch waterline within Aniani Street extending approximately 1,125 lineal feet along Aniani Street to the northern boundary of the southernmost lot(TMK 7-3-019:010) b. service laterals that will accommodate 5/8-inch sized meters to each lot, c. existing service laterals must be cut and plugged at the main, and r)1.1• '�1..; 1!!'\ i ,>I 11 I'I !ti til l'f'll .....
