Hawai`i County Community Facilities District No. 1-2021 (Kaloko Heights) DEM Director's Report of Facilities July 30, 2021 The FEA determined that the construction of the sewer line improvements will not have an adverse impact on any environmental resources, including but not limited to archaeological/cultural sites, endangered species or any other ecosystem. Furthermore,the proposed project would minimize the potential impact to the Kaloko-Honokohau National Historical Park's groundwater resources by eliminating the need to construct private wastewater treatment facilities immediately east(mauka) of these resources. Based on the approval of the FEA and the FONSI and the publication of the Notice in the Office of Environmental Quality Control's July 23, 2019, Environmental Notice,the proposed project has complied with the requirements of Chapter 343. 3. The general character and extent of the proposed improvements The CFD Project is an all-gravity system within Hina Lani Street and Ane Keohokalole Highway extending from the future Holoholo Street intersection with Hina Lath Street to the existing sewer line within Ane Keohokalole Street that services the County of Hawai`i's West Hawai`i Civic Center. (See Exhibit No. 2) The sewer line improvements consist of approximately 12,115 linear feet of polyvinyl chloride (PVC) sewer pipe, 39 sewer manholes and 11 laterals to adjacent properties. The sewer improvements have been designed to accommodate the projected wastewater flow from the full buildout of the Kaloko Heights Project,the Kaloko Heights Affordable Housing Project and the adjacent properties based on the existing zoning. 4. Land Acquisition The proposed sewer line improvements will be constructed entirely within the existing Hina Lath Street and Ane Keohokalole Highway rights-of-way. Therefore,the project will not require the acquisition of any additional land or easements to construct the proposed sewer line improvements. 5. Sewer Line Material The recommended material for the proposed sewer improvements are in conformance with DEM's standards and shall include,but are not limited to the following: o 257 Lineal Ft., 8-inch PVC SDR-26 sewer pipe and fittings o 6,167 Lineal Ft., 10-inch PVC SDR-26 sewer pipe and fittings o 5,691 Lineal Ft., 12-inch PVC SDR-26 sewer pipe and fittings o 14 Each, sewer manholes 5. 0'to 9.5' deep o 7 Each, lined sewer manholes 5. 0'to 9.5' deep o 2 Each, sewer manholes 9.51'to 15.0' deep o 5 Each, lined sewer manholes 9.51'to 15.0' deep 5
