Maile David, Council Chair and Members of the County Council County of Hawaii July 25, 2022 Page 4 mauka to makai with grades not exceeding 10 percent. The property was part of a subdivision in 2018 (SUB 18-01791), which subdivided TMK: 2-4-039:025 into two (2) parcels, including the subject parcel. The subject property is currently vacant of uses and structures. The property has been previously cleared and is overgrown with non-native plants and other invasive species. Upon rezoning and the subdivision into 33 lots, the landowners could potentially apply for an `Ohana dwelling, allowing for the construction of a second dwelling unit (meeting the criteria for an `Ohana dwelling) on each lot for a total of 66 dwelling units. The State Department of Health recommends restricting the density of the development using individual wastewater systems (IWS) to no more than 49 residential lots or dwelling units, because their rules state that subdivisions creating 50 or more lots/units may not be served by IWS at this time. State environmental law (HRS Chapter 343) also requires an environmental assessment review if a project proposes a wastewater treatment unit or IWS serving 50 or more dwelling units or the equivalent. Additionally, at this time there are 33 units of water available to the property to support the proposed subdivision, but more water units may be available in the future. Therefore, the Director would like to provide for the maximum density of dwellings allowed by the proposed RS-15 zoning to be established on the property, within the constraints or current law, and to account for changes in DOH wastewater law in the future. As such, a condition is included for the applicant to assign 16 accessory dwelling units (ADU's, also known as an `Ohana dwelling) to the 33 lots and restrictive covenants to restrict additional dwelling units above the 49-lot threshold that would trigger HRS Chapter 343 review and be contrary to current DOH wastewater rules. The condition will also allow the flexibility to be automatically modified to account for any changes in DOH wastewater rules in the future. Based on the preceding, the proposed RS-15 zoning would effectuate an increase in single-family residential density that would be consistent with the LDU LUPAG designation. This designation reflects the existing low density residential development in this area of Waiakea Uka. The area is predominantly urban and residential in character with some agricultural lots. Properties to the west are zoned Single-Family Residential (RS-15). Properties to the north, south and east are zoned Agricultural (A-3a & A-1 a). The majority of the area is within the State Land Use Urban district, including the subject property. There is a remnant parcel ("Camp 5-A" and TMK: 2-4-039:002) which is owned by the State of Hawaii, which is located between a portion of the subject parcel frontage with Ainaola Drive. The proposed change of zone would complement the existing land uses in this area and will provide for an orderly development of the area. All utilities and services are available to the site. The proposed subdivision will be accessed via two (2) road extensions from Haihai Street and Ainaola Drive. Additionally, there is a 5-foot future road widening setback along the boundary with Ainaola Drive. There will be two (2) cul-de-sacs built within the subdivision to access various lots. All newly
