The improvements set forth below shall be considered the minimum improvements necessary to protect the public health, safety and welfare: (Ord. 5-82, 7-20-1982)
A. Streets:
1. All streets and alleys within the platted area which are dedicated for public use shall be brought to grade approved by the governing body after receiving the report and recommendations of the City Engineer or designee. Street grades, wherever feasible, shall not exceed five percent (5%), with due allowance for reasonable vertical curves. No street grade shall be less than one-half (1/2) of one percent (1%).
2. All roadways shall be surfaced with Portland cement concrete or with asphaltic concrete over a crushed stone base as the governing body may require.
3. Curb and gutter shall be required on all streets.

4. 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 the foreseeable needs of the subdivision taken alone. The streets shall, upon final approval and acceptance by the City, become the property of the City. (Ord. 5-82, 7-20-1982; amd. 1998 Code)
B. Sanitary Sewer System:
1. The subdivider of the land being platted shall make adequate provision for the disposal of sanitary sewage from the platted area with due regard being given to present or reasonably foreseeable 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 the plans and specifications of the City and at the sewer grades as established by the City.
2. 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 platted area, but necessary to complete the City sanitary sewer 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 sewer and the diameter of sewer reasonable to meet the foreseeable needs of the area.
3. The above mentioned facilities for the collection and disposal of sanitary sewage from the platted areas shall, upon final approval and acceptance by the City, become the property of the City.
C. Storm Sewer System:
1. 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 area. The storm sewer system shall be constructed in accordance with plans and specifications of the City and at sewer grades established by the City.

Under some circumstances, the City may require, as a condition for approval of the plat, installation of a storm sewer system that is larger than necessary to meet the needs of the platted area, but necessary to complete the City storm sewer 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 sewer and the diameter of sewer reasonable to meet the foreseeable needs of the area.
3. The sewers shall, upon inspection, approval, and acceptance by the City, become the property of the City. In the storm sewer design phase, consideration shall be given to alternatives and principles of storm water management, or the provisions of a storm water management plan if such plan has been adopted by the City.
D. Water Main System:
1. 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 reasonably foreseeable needs of the entire area, and shall connect the same to the City's existing water mains.
2. 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.

3. The water mains shall, upon inspection, approval, and acceptance by the City, become the property of the City.
E. Other Improvements: The owner and subdivider of the land being platted shall be responsible for the installation of sidewalks within the street area; the installation of walkways as necessary; grading, seeding or sodding of all lots; the planting of any required trees in the parking area; the installation of street signs, and the provision of street lighting.
