County Council Transmittal of Kilohana Sewer Improvement District — Implementation Study, Kilohana Sewer Improvements Financing Analysis Report, and Finance Department Memorandum Page 4 of 6 o Gravity sewers; o Pump stations and force mains; and o Low pressure sewers. Provision of a centralized wastewater collection system will require the construction of a new underground wastewater collection system typically in or through existing roads or easements. To overcome areas of flat or hilly terrain, pressurized lines (including pump station and force mains and/or installation of low pressure sewers) may need to be included in the centralized wastewater collection system. Table 2 summarizes information from the Implementation Study on the main advantages and disadvantages of connecting to an existing regional wastewater system. • Whether any new land will be necessary to be acquired and the estimated cost thereof and the proportion of the cost which should be borne by the County: Except as noted below, the proposed Kilohana Subdivision sewer works will be constructed within existing County right -of -way and within sewer easements that reside on private properties where necessary. Except as noted below, maintenance of improvements or existing sewer works located on private property will be the responsibility of the respective property owners and/or homeowners association(s) and is not included as part of the County sewer system. An easement along State -owned street section within the Ali'i Kai Subdivision to Ali'i Drive for a portion of the main wastewater collection line would be necessary but at no anticipated acquisition cost. All other lands for the Kilohana Subdivision main collection system are planned to be routed within existing County right -of -way. The existing Kilohana Subdivision main collection system would be subject to inspection prior to acceptance by the County. Existing sewer easements, where applicable, would be conveyed to the County for maintenance access purposes. • The materials recommended to meet the conditions of the improvement: In accordance with the design standards, the recommended construction materials will include PVC pipe for gravity sewers and force mains. Material requirements are typically specified in details during the design stage. • The boundaries of the proposed improvement district and any sub - districts or zones therein as to which different portions of the cost of improvements should be charged: The improvement district boundary shown on Exhibit 3.2 was based on the study area established by the County with the intent of addressing Resolution No. 158 -04 ( "certain real property located at Holualoa, District of North Kona "). • The estimated cost of the improvement, the portions of the cost to be borne by the County and the portions of the cost to be assessed against the assessment units specially benefited with the maximum unit of assessment to be made against each assessment unit to be assessed: County of nawai'i is an Equal Opportunity Provider and Employer.
