A. 
The minimum improvements installed in any subdivision before the plat can be finally approved shall be in accordance with the following paragraphs:
1. 
The subdivider shall grade and improve all new streets and alleys, if any, within the subdivision area and such additional street rights-of-way as may be necessary along existing dedicated public streets which have been accepted for maintenance and are to be improved by the developer. The paving on such new streets and alleys shall be in accordance with the standards of the City. Grading for streets and alleys including necessary clearing and grubbing, removal of existing structures, excavating, filling, spreading and compacting shall be in accordance with the requirements set forth in this Article and in conformity with approved lines, grades, slopes and typical cross sections.
a. 
Material incorporated in fills shall be free of vegetable matter, frozen material and other deleterious substance and shall contain no large rocks or lumps.
b. 
Areas to be graded by cutting or filling shall be rough graded to within two-tenths (.2) of a foot of the accepted finished elevation after necessary allowance has been made for the thickness of pavement and base courses and other installations.
c. 
All tree stumps, masonry and other obstructions shall be removed to a depth of at least two (2) feet below the top of the finished subgrade.
d. 
Fill material shall be placed in layers which when compacted shall not exceed six (6) inches. Each layer shall be spread evenly and shall be blade mixed during spreading to ensure uniformity. Each layer of a fill shall be compacted by means of tamping or sheeps-foot rollers, multiple-wheel pneumatic tired rollers, successive passes of heavy earth-moving equipment or the equivalent. Rolling of each layer shall be continuous over its entire area and sufficient passes of the rolling equipment shall be made to ensure the desired maximum practical density has been obtained. In general, when the material being compacted ceases to shove and push under the moving compaction equipment or, in the case of tamping foot rollers, the roller "has walk out", sufficient density has been obtained. In no case, shall the density of the fill material be less than eighty percent (80%) of the American Association of State Highway Officials Standard T 99-49.
e. 
The top six (6) to eight (8) inches of finished subgrade, whether on a cut section or a fill section, shall be compacted to a density of at least ninety percent (90%) of the American Association of State Highway Officials Standard T 99-49. The compacted subgrade shall be continuous for at least one (1) foot beyond the pavement edge or beyond the back of curbs.
f. 
Finished grading shall provide profiles and cross sections reasonably satisfactory to the Department of Planning and Development. Graded slopes for fill sections shall not be steeper than the Department of Planning and Development determines to be reasonably satisfactory and cut slopes shall be consistent with the physical conditions at any given cut section.
g. 
Prior to the application of base and surface course materials, the City shall inspect the grading for streets and alleys to determine that the requirements for grading and other requirements hereof have been fulfilled. It shall be the responsibility of the subdivider to notify the Department of Planning and Development not less than forty-eight (48) hours in advance that work is to be ready for inspection.
h. 
The paving crown and curb on end of such new streets and alleys shall be of a character suitable for the expected traffic and in harmony with similar improvements in the surrounding areas. Where asphaltic macadam surfacing is used, the specifications shall include a seven (7) inch, two (2) course waterbound macadam base and a two (2) inch asphaltic penetration or asphaltic concrete surface in accordance with the standard specifications of the County Highway Department. Concrete curb and gutter of the lip type having a width of two (2) feet shall be required along the edges of asphaltic streets with the curb and gutter to be included in the width of paving specified in Section 405.360. Concrete pavements shall be installed with a minimum thickness of six (6) inches in accordance with the standard specifications of the City with the curb and gutter being an integral part of the concrete pavement.
2. 
The subdivider shall, whenever necessary, grade any portion of the property subdivided into lots so that each lot will be usable and suitable for the erection of residential or other structures thereon.
3. 
If outlets are within reasonable distance, the subdivider shall install storm water and sanitary sewers and provide a sanitary sewer connection for each lot. Such installation shall be in accordance with the standards and specifications of the City and before the improvements are started, the plan therefor shall be approved by the engineer of the sewer district in the area within which the subdivision lies. If no outlets are within reasonable distance, the subdivider shall make such provisions for sanitation as will satisfy the City and County health officials and before the plat shall be approved, the subdivider shall present to the Planning and Zoning Commissioner an order from the City and County health officials showing that the provisions will properly care for and protect the health, safety and welfare of the existing and probable future population within the subdivision and surrounding area.
4. 
The detailed plans for the proper disposal of storm water affecting the proposed subdivision shall show the location of all open drainage channels, together with such improvements which may be necessary, such as widening, straightening, surfacing or other improvements of such channels, reconstruction or construction of new bridges, culverts and the construction of all underground enclosed pipe sewers and surface accessories necessary to efficiently carry off the storm water and prevent ponding on the surface of the proposed subdivision. The plans for these facilities shall be shown both in plan and profile with details of all necessary accessories. The datum regarding the area to be served by the facilities and the estimated runoff from the area tributary to the facilities beyond the subdivision shall accompany the detailed plans.
5. 
The subdivider shall install water mains and fire hydrants in the subdivided area. Such installation shall be in accordance with the standards and specifications of the County water company and the location of the hydrants shall first be approved by the Fire Chief and the State Inspection Bureau.
B. 
It is also desirable to install other improvements such as trees, electric lines, gas mains and similar facilities in any subdivision. When the Planning and Zoning Commission and the Board of Aldermen deem it necessary, they may require that any such improvements shall be installed before the plat is approved.
[R.O. 2009 §22-58; Code 1969 §37-21; Ord. No. 3148 §1, 7-1-1991]
