Hawai`i County Community Facilities District No. 1-2021 (Kaloko Heights) DEM Director's Report of Facilities July 30, 2021 Total Sewer Improvement Cost $11,496,724 A more detailed summary of the construction costs is included in Appendix D, Engineer's Opinion of Probable Cost. 8. Necessary Plans,Data, Detail and Specification All necessary plans and other data, details and specifications for the improvements and any other matters or details intended to apply thereto are contained in the Sewer Line Improvements approved by the Department of Public Works on August 13, 2020, Department of Water Supply on September 11, 2020, and DEM on November 18, 2020. A set of the approved construction plans and specifications is available upon request. 9. Public Interest The construction of the sewer improvements will allow the wastewater from the Project Area as well as the Kaloko Heights Affordable Housing Project to be transmitted to and processed at the County's Kealakehe WWTP. This will eliminate the need for the construction of private wastewater treatment facilities serving these projects. Future connections to the sewer line improvements from other properties are also made possible due to the size and capacity of the sewer line improvements,which will have a design flow capacity of approximately 1 million gallons per day(the Kaloko Heights Project Area and Kaloko Heights Affordable Housing Project are estimated to generate approximately average daily flow of 364,000 gallons at full buildout). Furthermore,the proposed sewer line improvements: o are consistent with the Hawai`i County General Plan's North Kona's Sewer Course of Action to "expand the existing sewer collection system" and the Kona Community Development Plan's (CDP)polices related to public utilities, including Policy PUB-4.4 (encourage hookup to County sewer system to protect nearshore waters), and Action PUB-4.4c (update sewerage master plan to service the entire Kona Urban Area). o reduce/minimize impacts on the groundwater resources, if any, including the anchialine ponds and nearshore water within the Kaloko-Honokohau National Historical Park. o reduce development costs for HICDC's low-income rental project o provide sewer service delivery capacity to the adjacent properties to sewer system at no cost of construction. Based on the above,the proposed Hawai`i County Community Facilities District No. 1-2021 (Kaloko Heights)will be in the public interest in accordance with the requirements of HCC Chapter 32. 7
