(a) Every subdivision shall be provided with a storm water sewer or drainage system, adequate to serve the area being platted and otherwise meeting the approval of the officials having jurisdiction.
(b) Where a public sanitary sewer main is reasonably accessible, in the opinion of the Commission, the subdivision shall be provided with a complete sanitary sewer system connected with such sewer main, including a lateral connection for each lot. The installation of the sewer system shall be the responsibility of the developer, at his cost or at the discretion of the City Council. Where a public sanitary main is not reasonably accessible, in the opinion of the Commission, proper provisions shall be made for the disposal of sanitary wastes by one or the other of the following methods, as the case may be:
(1) In the case of a subdivision in which the average size of lots is less than one-half commercial acre (twenty thousand square feet), the subdivision shall be provided with a complete sewer system including a lateral connection for each lot, and a community sewage treatment plant or disposal facilities of a type meeting the approval of the officials having jurisdiction. The right of the City to charge the property owners the actual cost of operating and maintaining such treatment plant or facility shall be filed with the final or record plat and incorporated in each deed.
(2) In the case of a subdivision in which the average size of lots is one-half commercial acre (twenty thousand square feet) or more in area, and where the officials having jurisdiction deem appropriate, based on soil and other conditions as determined by percolation and other tests, private restrictions shall be filed with the final or record plat and incorporated in each deed calling for the installation on each lot of an individual sewage disposal system meeting fully the requirements of the officials having jurisdiction.
