The following requirements are applicable to all subdivisions within the city.
(A) Water lines. Where an approved public water supply is within reasonable access to the subdivision as determined by the number of lots, distance from and capacity of existing mains, water lines shall be placed within the right-of-way of each street.
(1) Water lines shall have a minimum diameter of six inches. Fire hydrants shall be installed at intervals of not less than 400 feet. The minimum size water main shall be six inches in diameter and all water mains shall be looped so that water is available from two directions to any point. Water mains, fire hydrants, gate valves and appurtenances shall be installed in accordance with acceptable engineering practice.
(2) Each lot shall be provided with a connection to the water main. In general, in new residential areas, water main services with a shutoff shall be installed to appropriate public recreational areas with the water main construction.
(B) Sanitary sewers. Sanitary sewers shall be constructed in accordance with a connection to a sanitary sewer. The city may accept an area for platting where that service cannot be provided when the lots are of sufficient size and the soil is suitable for private systems in accordance with city and state Health Department recommendations. No private disposal systems shall be interconnected or run to a common private or public drain. The minimum size public sanitary sewer shall be eight inches in diameter. In general, in new residential areas, sanitary sewer services shall be installed to appropriate public recreational areas with the sewer construction. Sewage lift stations will be constructed if necessary to serve an area; provided, a lift station will be constructed on an assessment basis. The lift station cost beyond the area immediately assessable will be held for future assessment to the future area to be served.
(C) Storm drainage. All necessary facilities including underground pipe, manholes, inlets, catch basins and other appurtenances necessary to provide adequate drainage for the property or to maintain any natural drainage course shall be the responsibility of the developer. Open drainage ditches will not be allowed unless specifically directed by the City Engineer.
(1) Platting of property is prohibited unless it is possible to drain the property by gravity drainage to the natural drainage course for the area. At a minimum, no property plat will be accepted unless street grades are at least five feet above lake elevation so as to drain into the streets. The meeting of this requirement does not obligate the Council to accept the plat if there are substantial obstructions to the drainage of the property contained therein, and the Council may require that the subdivider install pumping facilities for storm drainage prior to plat acceptance if those facilities are necessary.
(2) Storm drainage and retention ponds shall be required and designed in accordance with state statutes.
(D) Extensions not in platted area. In some cases, the proposed area to be platted will not be served at its borders by water mains or sanitary sewer. The Council may require a petition for the creation of an assessment district to extend the facilities to the platted area; or may require the subdivider to pay the cost of extension; or may accept the plat with a separate water or sewer system; or may pay the cost thereof and hold the amount for future assessment; or may refuse acceptance of the plat.
(E) Building permit. No building permit shall be issued in the platted area until sewer and water mains are designed, approved and the contract for installation awarded with a satisfactory completion date.
(1) No building shall be occupied in the platted area until provided with sanitary sewer and water service and until the street is graveled and the graveling accepted as adequate by the City Engineer to serve the building.
(2) The occupancy of a building in violation of this division (E) shall not relieve the subdivider of any responsibility for street improvement. The transfer of property in the plat from the original subdivider to other parties shall not relieve the subdivider of the responsibility for initial street work as defined herein.
(F) Design of improvements. The City Engineer will design only the improvements to be installed by the city. A subdivider desiring to contract and install his or her own improvements shall have plans and specifications prepared by a registered engineer of the state, which have been approved by the City Engineer and state agencies before construction begins. All street, sanitary sewer, storm sewer and water main improvements installed by the subdivider shall be inspected by the City Engineer, and the Engineer shall furnish a written statement to the subdivider of city acceptance of the utility improvements or street as part of the city system. Any corrections to the improvements found necessary by the City Engineer shall be done by and at the expense of the subdivider before acceptance is made.
