[R.O. 1994 § 410.230; Ord. No. 94-8 Sub. Reg. Art. 7 § 1, 5-10-1994]
A. 
The subdivider shall install or provide for the installation of the following improvements:
1. 
Streets.
a. 
Streets in subdivisions comprised of lots smaller than three (3) acres shall be hard surfaced with curb and gutter in conformance with the engineer's standards and specifications.
b. 
Streets in subdivisions comprised of lots larger than three (3) acres but less than five (5) acres in size shall be hard surfaced in conformance with the engineer's standards and specifications. Curbs and gutters shall not be required.
c. 
Streets in subdivisions comprised of lots five (5) acres and larger in size shall have a compacted base and be surfaced with rock and gravel in conformance with the engineer's standards and specifications.
2. 
Water. Where a public water supply is proposed to serve the subdivisions, said water lines shall be installed in proper easements or within the limits of the street and alley right-of-way. The system shall be of equal or better quality and size than the minimum standards of the City and shall meet all State Department of Natural Resources (DNR) standards. Where private water supplies are proposed, adequate provision shall be made for easements to allow installation of a public system should the property ever be annexed or required to develop a public supply. Private water systems shall meet all requirements of the State DNR.
3. 
Sewer.
a. 
A public sanitary sewer will be used in all subdivisions wherever possible. The sewer shall be designed and constructed to provide service to each lot within the subdivision. The system of lateral sewers shall collect the sewage within the subdivision and discharge it into the City sewer system. All subdivisions which connect to the City sewer systems shall be required to be annexed into the City. Upon determination of the City that the City sewer system is not practicably available to the development, the subdivider may submit plans for consideration for disposal of sewage into a central, public treatment facility or a private system. The sewer system shall be of equal or better quality and size than the minimum standards of the City as determined by the City Engineer. The sewer system shall meet all State DNR standards.
b. 
In subdivisions where individual private wastewater systems are proposed, adequate provision shall be made for easements to allow the installation of a public system should the property ever be annexed or required to develop a public system.
4. 
Walks. Sidewalks shall be installed on both sides of all arterial and collector streets and on both sides of the street in a commercial district. All sidewalks shall be not less than four (4) feet in width of Portland cement concrete and shall comply with the specifications of the Governing Body. Walks shall also be installed in any pedestrian easements as may be required by the Planning and Zoning Commission. Installation of sidewalks may be delayed for one (1) side of a block between two (2) intersecting streets until seventy-five percent (75%) of the lots on that side of the block have been developed or within three (3) years of the approval of the final plat, whichever comes first.
5. 
Storm Drainage. The subdivider shall install culverts, storm sewers, rip-rap slopes, stabilized ditches, stormwater detention facilities and other improvements necessary to adequately handle stormwater. All improvements shall comply with the minimum standards of the City and shall be approved by the City Engineer prior to construction.
a. 
Where developments are determined by the City Engineer to be in close proximity to unimproved stream channels, an engineering study shall be required to determine the stability of the stream banks. The study shall evaluate the likelihood that normal stream bank slippage, failure and erosion will endanger structures proposed as a part of the development or the yards of residential lots. Such studies shall analyze the impact of full upstream development as shown on the City's Comprehensive Plan map and include a complete identification and analysis of the soil profile and underlying bedrock upon which the development is to take place. Based on this analysis, engineering plans shall be submitted showing the structural measures to be used to stabilize those banks which are determined to be unstable. The study shall be submitted concurrent with the application for final plat approval and shall be reviewed and approved by the City Engineer prior to recording the plat. Storm drainage easements may be required where necessary to allow ongoing maintenance of the stream channel and any stabilization measures.
b. 
The City shall pay for the installation of all storm sewer curb inlets, manholes and pipes required for the development of subdivisions.
c. 
Detention basins or ponds, paved drainage ditches and other items determined by the Planning and Zoning Commission and Board of Aldermen to be an unusual or excessive requirement for development of the property shall be installed at the developer's expense.
6. 
Street Signs. The City shall install street signs at all intersections within a subdivision.
7. 
Street Trees. Street trees should be planted in accordance with proper landscape design standards and site plan review requirements.
8. 
Permanent Monuments. Permanent monuments shall be placed at all lot and block corners, angle points, point of curve in streets and at intermediate points as required prior to the final acceptance of the plat by the City. Said permanent monuments shall be one-half (1/2) inch minimum iron bars or pipe, eighteen (18) inches long, shall be set with top of monument flush with existing ground line and shall include an identification cap on the bar.
9. 
Street Lights. The City shall provide for the installation of street lights at street intersections and other locations as it determines necessary. The developer shall be responsible for all costs for providing street lighting equipment other than that determined as necessary by the City.
[R.O. 1994 § 410.240; Ord. No. 94-8 Sub. Reg. Art. 7 § 2, 5-10-1994]
A. 
Where the proposed subdivision is a resubdivision or concerns an area presently having any or all required improvements as previously set out and where such improvements meet the requirements of this Article and are in good condition as determined by the Governing Body upon its consideration of the opinion of the City Engineer, no further provision need be made by the subdivider to duplicate such improvements. However, where such existing improvements do not meet said requirements as determined by the Governing Body upon its consideration of the opinion of the City Engineer, the subdivider shall provide for the repair, correction or replacement of such improvements so that all final improvements will then meet said requirements as determined by the Governing Body upon its consideration of the opinion of the City Engineer.
B. 
Where the proposed subdivision is a resubdivision or concerns an area presently abutting or continuing any existing public street of less than the minimum required right-of-way width or roadway width, land shall be dedicated so as to provide a minimum street right-of-way width established by these regulations and/or by the policy of the Governing Body; and the subdivider of such proposed subdivision shall provide an additional roadway pavement meeting the minimum standards set by these regulations and the Governing Body. The Governing Body shall determine what adjustment to make where the aforesaid widening merges with existing streets which are of smaller width at the boundary of such proposed subdivision. The Governing Body may reduce the minimum roadway system in the proposed subdivision if the extension of such roadway is already improved at each end of such roadway in the subdivision and the roadway in the proposed subdivision is two (2) blocks or less in length.
