Section 4606 - Establishment of the county district(a) Upon the evidence presented at the public hearing, and after due consideration of the maps and plans, reports, recommendations and other data filed with it, the county government shall determine by resolution whether or not the proposed district and facilities are satisfactory and sufficient, and if it shall determine such question in the negative, it may proceed to make a further study. The county government may make such further study and amend and revise the maps and plans and estimate of cost in conformance with its findings. If the revised maps and plans and revised estimate alter the estimated maximum expenditure for the project, alter the boundaries of the proposed district, alter the boundaries of zones of assessment or change the allocation or cost of the facilities as between zones of assessment, the county government shall call a further public hearing thereon in the manner provided in § 4604 of this title. When the county government shall find that the proposed district and facilities are adequate and appropriate, it shall further determine by resolution (1) whether all the property and property owners within the proposed district are benefited directly or indirectly thereby, (2) whether all of the property and the property owners so benefited are included within the limits of the proposed district, (3) whether it is in the public interest to establish the district, and (4) if said maps and plans and reports recommend the establishment of zones of assessment and the allocation of the cost of the facilities as between such zones of assessment, whether such zones of assessment and the allocation of the cost of the facilities thereto represent as nearly as may be the proportionate amount of benefit which the several lots and parcels of land in such zones will derive therefrom.(b) If the county government shall determine that it is in the public interest to establish the district, but shall find that (1) any part or portion of the property or property owners within the proposed district are not benefited directly or indirectly thereby, or (2) that certain property owners benefited directly or indirectly thereby have not been included therein, or (3) if zones of assessment are proposed to be established and the cost of facilities allocated among said zones of assessment, that any part or portion of the property of property owners within a proposed zone of assessment should be placed in a different zone or that a different allocation of the cost should be made as between the zones of assessment, the board shall cause the necessary changes of the boundaries of the proposed district, or the necessary changes of the boundaries of any proposed zone of assessment or the necessary changes as to the allocation of costs, as the case may be, to be made, and the board shall call a further hearing at a definite place and time not less than 10 nor more than 30 days after such determination. Notice of such further hearing shall be published in the manner provided in § 4604 of this title, except that such notice shall also specify the manner in which it is proposed to alter the boundaries of the proposed district, or the boundaries of the zones of assessment or the allocation of the cost of the facilities as between said zones of assessment, as the case may be. If and when the board shall determine in the affirmative all of the questions set forth above, the board may adopt a resolution approving the establishment of the district, as the boundaries shall be finally determined, and the construction of the improvement, and if zones of assessment have been established and an allocation of the costs of the facilities made as between such zones of assessment, further approving the establishment of the initial zones of assessment and the initial allocation of the costs of the facilities as between said zones of assessment. Such resolution shall be subject to referendum upon petition as hereinafter provided.9 Del. C. 1953, § 4606; 56 Del. Laws, c. 103, § 13.;
