22 PROIECl' PH_1SING AND BASIS FOR PROJECT <br />I be 114 one -acre and larger lot; are approximate in number because some lots will overlap with <br />existing A-1 a zoned land to the east. The proposed agricultural one -acre subdivision is planned to <br />be developed in phases based on market demand. <br />'I he initial phase is within the existing zoned A-1 a portion to the north of the proposed Puainako <br />Street Extension, which has been considered in the plan. 'I he one acre lots will be served by County <br />standard roadways. The land is divided by existing natural drainage courses, which will be partially <br />improved. Drainage easement, will be created on individual lots to keep habitable structures out of <br />flood hazard zones. <br />'I he zone change request was based on economic realities of land development. In order to cover <br />the costs of development, including roads, water system, and electricity, while providing lots that can <br />be sold at market prices, the smaller lot size is required'. The lot sizes are expected to allow for <br />"subsistence" agriculture which can provide for family and hobby uses, and limit oversupply to the <br />local market. Profitable commercial agriculture is not likely feasible at this scale, nor is it guaranteed <br />at larger scales. The lots are designed to sell for approximately$100,000. <br />2.3 INFRASTRUCTURE CONSIDERATIONS <br />WATER SUPPLY SYSTEM <br />Water will be provided to the project site from the County of Hawaii, Department of Water Supply <br />DWS) system. Presently the new Saddle Road Well is the main source of water, supplying the <br />Saddle Road Reservoir. <br />According to the County Department of Water Supply (DWS) in a letter dated March 13, 2003, the <br />Department will support the proposed zone change and provide water units to support a <br />subdivision of up to 7 units per lot of record, or 35 units of water. A booster pumping system will <br />be provided for any further subdivision above the 7 units of water per lot of record (Attachment 2). <br />The applicant proposes to complete the subdivision with water units in phases, and will thereafter <br />construct a booster pump station to accommodate subdivision of the remaining lots. Water supply <br />for the booster pump station will be provided by other reservoirs in the service area including the <br />Piihonua Reservoir. <br />SEWERAGE <br />The proposed project will consist of 5 total parcels (TMKs) due to subdivision by the Puainako <br />Street Extension. According to the State Department of Health (DOH), Fnvironmental <br />Management Division, any development which exceeds 50 lots per parcel of record will require a <br />
