[Ord. No. 1137, 6-17-2008]
The purpose by which land is subdivided into blocks and lots is a matter of great mutual concern to the subdivision developer and the City. The street pattern, the size of lots and the utilities installed usually become permanent features of the community for all time so that mistakes in subdivision development may cause great financial loss to the developer and continual excessive maintenance expense to the City.
It is the intent and purpose of this chapter to regulate the subdivision of land so as to obtain functional street layouts, so as to provide adequate sized lots which are in conformity with the highest and best use of the land, so as to provide for adequate open spaces for traffic, schools, recreation and air, so as to ensure the installation of adequate sized utilities and adequately improved streets, and so as to provide for other features of the master plan, all to the end that the development of land may proceed in an orderly manner, good livable neighborhoods with all of the needed community facilities may be created and excessive City maintenance expense may be avoided.
Every owner of any lot, tract, or parcel of land within the City who may hereafter subdivide the same into two or more lots, sites or other divisions of land for the purpose, whether immediate or future, of transfer of ownership or building development shall submit a subdivision plat to the City Planning Department in accordance with this chapter and comply with all other provisions of this chapter.

d. 
Half streets shall be prohibited except where essential to the reasonable development of the subdivision in conformity with the other requirements of these regulations or where it is found to be practicable to require the dedication of the other half when adjoining property is subdivided.
e. 
Under normal conditions streets and private ways shall be laid out so as to intersect as nearly as possible at right angles, except where topography or other conditions justify variations. More than four approaches to any intersection shall be prohibited.
f. 
Alleys shall be provided in commercial and industrial districts except where other definite and assured provision is made for service access.
g. 
Streets within the boundaries of the subdivision shall be designed and graded to the full right-of-way width.

No other surface improvements or fill, except bank stabilization structures, poles and sign structures, shall be placed in any such easement right-of-way.
[Ord. No. 1137, 6-17-2008]
Inasmuch as the primary purpose of subdividing land is to create residential building sites or commercial or industrial building sites and inasmuch as vehicular access and certain utilities are essential to urban development, it shall be the responsibility of the subdivider, or his assigns or successors in interest to the subdivision, to install, in accordance with plans, specifications, and data approved by the City Engineer, certain required improvements as follows:
1. 
Staking. The following described monuments shall be installed before the City Engineer shall approve the plat, or in lieu thereof a performance bond in an amount equal to the cost of doing such work shall be furnished to the City before the City Engineer shall certify to the council that required improvements have been satisfactorily arranged for:
(a) 
The external boundaries and corners of blocks shall be monumented by iron rods or pipes not less than two inches in diameter and extending at least 30 inches below grade.
(b) 
Lot corners, all points of curvature, points of tangency, and other points not required to be marked by § 12-109(1)(a) shall be monumented by iron rods or pipes not less than one inch in diameter and extending at least 24 inches below grade.
2. 
Street Grading. All full-width streets and private ways located entirely within the boundary of the subdivision shall be graded to a minimum width of nine feet back of both curblines to within six inches of the grade established by the City Engineer. All major and collector streets bordering the subdivision shall be graded as above on the side of the street adjacent to the subdivision, provided the grade of the existing major or collector street unsatisfactory to the City Engineer, the street will be graded to the maximum extent possible while matching the existing street grade according to plans approved by the City Engineer. Such grading shall be completed, or in lieu thereof a performance bond in an amount equal to the cost of doing such work shall be furnished to the City before the City Engineer shall certify to the Council that required improvements have been satisfactorily arranged for.
3. 
Street Surfacing.

Major and collector streets adjacent to the subdivision shall be widened one lane adjacent to the subdivision at each intersection of a subdivision street and the major or collector street. At such time as the City or the County is prepared to proceed with a major street improvement project adjacent to the subdivision, the subdivider or the sanitary and improvement district containing the subdivision will pay for one lane of paving.

Where a City sanitary sewer is accessible by gravity flow within 500 feet of the final plat, the subdivider shall connect thereto and provide adequate sewer lines and stubs to benefit each lot. Where a City sanitary sewer is not accessible by gravity flow within 500 feet of the final plat, the subdivider shall make provisions for the disposal of sewage as required by law. Where a City sanitary sewer accessible by gravity connection is not within 500 feet of the final plat, but where plans for the installation of City sanitary sewers within such proximity to the plat have been prepared and construction will commence within 12 months from the date of the approval of the plat, the subdivider shall be required to install sewers in conformity with such plans.

The bond or certified check shall be released upon installation of the required improvements and approval thereof by the City Engineer. Such periods may be extended by the City Council upon a showing by the developer that lot sales and development do not warrant such installation. If the improvements are not completed within the specified or extended periods of time, the performance bond shall be forfeited and used by the City to complete the installation of the improvements.
11. 
Civil Defense Warning System. If the subdivision is not within audible range of an existing civil defense warning siren, a civil defense warning system siren subject to standards and regulations established by the City Civil Defense Director shall be installed.
