(1) 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 meet- ing 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. (2) Grading. The full width of the right-of-way of each street and alley dedicated in the plat shall be graded. (3) Pavement. All streets and alleys shall be im- proved with concrete or bituminous surface except as may be approved by action of the governing body. (4) Gravel Surface. Streets in an Agricultural or Residential area may be surfaced with six (6) inches of stabilized gravel to a surface width of thirty-two (32) feet, if the average lot abutting the street is over four (4) acres in area and has a width over three hundred (300) feet at the building setback line, and if the governing body determines it would cause an undue hardship because of the lot sizes to require a concrete or bituminous surface and that the lots as platted will probably not be resubdivided into smaller lots within five (5) years. (5) Curb and Gutter. There shall be concrete curb and gutter installed along both sides of all streets and alleys that are of an urban design. (6) Sidewalks. These may be required along both sides of all streets in areas where residential density equals or exceeds three (3) dwelling units per net acre of residentially used land or in commercial areas. (7) Water Mains. In the case where mains from a public water system are available, the sub- divider shall be required to install water mains in the plat and connect the same to such public water system. (8) 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 (5) years, the governing body 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 expen- sive connection to the sewer when it becomes available and usable. Where such on-site units are installed, the subdivider shall provide under- ground plumbing to extend three (3) feet beyond the footing which plumbing shall be 11 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. (9) Drainage Facilities. Such facilities and ease- ments 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 flood plain management, proper drainage, prevention of erosion, pedestrian access to water bodies, or other public purpose. If there is a water shed district, that board must approve all surface water drainage. (10) Miscellaneous Facilities. Tree planting, street name signs, traffic control signs, oversized utility trunk lines, pedestrian ways, and other improvements may be required. 802. Payment For Installation of Improvements. 802.01. The required improvements as listed else- where are to be furnished and installed at the sole expense of the subdivider. However, if the cost of an improvement would by general policy be assessed only in part to the improved property and the remaining cost paid out of general tax levy, provision may be made for the payment of a portion of the cost by the community. Further, if any improvement installed within the subdivision will be of substantial benefit to lands beyond the boundaries of the subdivision, provision may be made for causing a portion of the cost of the improvement, representing the benefit to such lands, to be assessed against the same. In such a situation the subdivider will be required only to pay for such portion of the whole cost of said improvement as will represent the benefit to the property within the sub- division. 803. Agreement Providing for the Installation of Improvements. 803.01. Prior to the installation of any required improvements and prior to approval of the plat, the subdivider shall enter into a contract in writing with the community requiring the subdivider to furnish and con- struct said improvements at his sole cost and in accordance with plans and specifications and usual contract conditions. This shall include provision for supervision of details of construction by the engineer and shall grant to the engineer authority to correlate the work to be done under said contract by any subcontractor authorized to proceed thereunder and with any other work being done or contracted by the community in the vicinity. The agree- ment shall require the subdivider to make an escrow deposit or, in lieu thereof, to furnish a performance bond, the amount of the deposit or penal amount of the bond to be equal to 125% of the engineer's estimate of the total cost of the improvements to be furnished under the contract, including the cost of inspection. On request of the subdivider, the contract may provide for completion of part or all of the improvements covered thereby prior to acceptance of the plat. In such event the amount of the deposit or bond may be reduced in a sum equal to the
