Prior to the approval of a plat by the City Council, the subdivider shall have agreed, in the manner set forth below, to install, in conformity with approved construction plans and in conformity with all applicable standards and ordinances, the following improvements on the site.
(A) Survey monuments. All subdivision boundary corners, block and lot corners, road intersection corners and points of tangency and curvature shall be marked with survey monuments meeting the minimum requirements of state law. All U.S., state, county and other official bench marks, monuments or trangulation stations in or adjacent to the property shall be preserved in precise position unless a relocation is approved by the controlling agency.
(B) Grading. The full width of the right-of-way of each street and alley dedicated in the plat shall be graded for an urban design roadway.
(C) Pavement. All streets and alleys shall be improved with concrete or bituminous surface except as may be approved by action of the City Council.
(D) Curb and gutter. Along both sides of an urban designed street, curb and gutter shall be installed. Concrete curb and gutter is recommended, however, bituminous curbing would be permitted if approved by the City Council.
(E) Sidewalks. These may be required along both sides of all streets in areas where residential density equals or exceeds three dwelling units per net acre of residentially used land or in commercial areas.
(F) Water mains. In the case where mains from a public water system are available, the subdivider shall be required to install water mains in the plat and connect the same to such public water system.
(G) Public sanitary sewer. In all cases where trunk line sanitary sewer facilities are available, the subdivider shall be required to install sanitary sewers in the plat and connect the same to such trunk line sewers. If such facilities are not available but it is expected they will be within five years, the City Council may require that such sewers, together with all necessary laterals extending from the main sewer to the street curb shall be installed and capped for future connection as service becomes available. In that event the subdivider may also install on-site disposal units provided they are so located as to permit easy and the least expensive connection to the sewer when it becomes available and usable. Where such on-site units are installed, the subdivider shall provide underground plumbing to extend three feet beyond the footing which plumbing shall be plugged. The area around the stack shall be scored so that the septic tank line can be disconnected and connection can be made with the public sanitary sewer system.
(H) Drainage facilities. Such facilities and easements shall be installed as will adequately provide for the drainage of surface waters; a storm sewer system may be required. Drainage way easements or land dedication may be required when such easements or land is needed in the public interest for purposes of floodplain management, proper drainage, prevention of erosion, pedestrian access to water bodies, or other public purpose. If there is a watershed district, that Board must approve all surface water drainage.
(I) Miscellaneous facilities. Tree planting, street name signs, traffic-control signs, oversized utility trunk lines, pedestrian ways and other improvements may be required.
