The improvements set forth below shall be considered the minimum improvements necessary to protect the public health, safety, and welfare. Design of the improvements shall be in accordance with the Engineering Standards adopted by resolution by the Hiawatha City Council in accordance with Hiawatha Code Section 165.58.
(Ord. 923 - Feb. 19 Supp.)
1. Streets. The subdivider of land being subdivided shall provide the grading of the entire street right-of-way, alley, or public place and provide appropriate paving, including curb and gutter on all streets. All streets or alleys shall be of such width and shall be so constructed as to meet City Standards. Under some circumstances, the City may require, as a condition for approval of the plat, dedication and improvement of a street having a width greater than necessary to meet the needs of the platted area but necessary to complete the City street system as it relates to both the area being platted and other areas. In such event, the City will pay the subdivider the difference in cost of improving the wider street and the street width reasonable to meet foreseeable needs of the subdivision taken alone. The streets shall, upon final approval and acceptance by the City, become the property of the City.
2. Sanitary Sewer System. The subdivider of the land being platted shall make adequate provision for the disposal of sanitary sewage from the platted area with due needs. There shall be constructed, at the subdivider’s expense, a sanitary sewer system, including all necessary pumping stations, pumping equipment, manholes, and all other necessary or desirable appurtenances to provide for the discharge of sanitary sewage from all lots or parcels of land within the platted area to a connection with the City’s sanitary sewers. The sanitary sewer system shall be constructed in accordance with City Standards and at the sewer grades as established by the City. Under some circumstances, the City may require, as a condition for approval of the plat, installation of a sanitary sewer that is larger than necessary to meet the needs of the City sanitary sewer as it relates to both the area being platted and other areas. In such event, the City will pay the subdivider the difference in cost of pipe and installation between the larger sewer and the diameter of sewer reasonable to meet the foreseeable needs of the area. The above mentioned facilities for the collection and disposal of sanitary sewage from the platted area shall, upon final approval and acceptance from the City, become the property of the City.
3. Storm Sewer System. The subdivider of land being platted shall install and construct a storm sewer system adequate to serve the area, including anticipated extension of use to serve additional areas. The storm sewer design shall comply with the provisions of a storm water management plan which has been adopted by the City in Chapter 162 of the Hiawatha Code of Ordinances. The storm sewer system shall be constructed in accordance with the City Standards. Such sewers shall, upon inspection, approval and acceptance by the City, become the property of the City.
EXCEPTION: Detention basins and associated inlets and outlets as part of the runoff control required by Chapter 162 shall not become the property of the City unless the Council accepts these portions of the system by resolution.
4. Water Main System. The subdivider of land being platted shall install and construct a water main system to adequately serve all lots or parcels of land within the platted area, with due regard to the present and reasonable foreseeable needs of the entire area, and shall connect the same to the City’s existing water mains. The water main system shall be constructed in accordance with City Standards. Under some circumstances, the City may require, as a condition for approval of the plat, installation of a water main that is larger than necessary to meet the needs of the platted area, but necessary to complete the City water distribution system as it relates to both the area being platted and other areas. In such event, the City will pay the subdivider the difference in cost of pipe and installation between the larger water main and the diameter of water main reasonable to meet the foreseeable needs of the area. The water mains shall, upon inspection, approval, and acceptance by the City, become the property of the City.
5. Other Improvements. The owner and subdivider of the land being platted shall be responsible for the installation of sidewalks within the street area, as defined in Section 165.58(3), the installation of walkways as necessary; grading, seeding or sodding of all lots; the planting of any required trees in the parking as defined in Section 165.47; the installation of street signs and the provision of street lighting. All such improvements shall be under the direction of the City Engineer or director of the electric utility, as appropriate.
