The improvements required shall be determined according to the accessibility of a sewer system and a public water supply, the relationship to existing or planned streets and according to the type and size of lots required by the zoning code in the district in which the subdivision is located.
(a) Improvements within the Subdivision. Land for right-of-way for all local streets within the subdivision and for all secondary or major streets within or on the boundary of the subdivision shall be dedicated by the developer, and all easements shall be provided.
Utilities and pavements shall be furnished and installed as hereinafter required; and they shall be of such sizes and capacities as are required for the development of the proposed subdivision, and as may be necessary to serve adjacent undeveloped land which is an integral part of the service area, provided however, the developer may not be required to pay for that part of the construction of the pavements of major streets, trunk line sewers or water mains which are determined by the Commission to be in excess of the size required for the development of the subdivision and integral service area.
The developer shall be required to extend improvements to the boundary of the proposed subdivision to serve adjoining unsubdivided land; however, where the Commission determines that a connecting street is necessary for the future subdividing of adjoining land but the present construction of pavement and/or utilities thereon are not warranted, the Commission may require the dedication of land for such connecting street and the pavement intersections constructed, utilities extended five (5) feet beyond the pavement and connections made available for future extension by other developers.
(b) Off-Site Extensions. The construction of off-site improvements to serve a proposed subdivision may be required of the developer as a precedence to approval if adequate utilities or streets are not available at the boundary of the proposed subdivision, provided the Commission finds the extension of the improvements across undeveloped or unserved areas would not be warranted as a special assessment to the intervening properties or a municipal expense until some future date.
(c) Determination of Scope of Improvements. In making determinations for the reasonable participation by the developer for the construction of off-site extensions or a major street, trunk line or water main the Commission shall consider in addition to the standards set forth in this chapter and other regulations of the City, the following conditions:
(1) The relative location and size of the proposed subdivision,
(2) The traffic estimated to be generated by the development in relation to present streets,
(3) The natural drainage area for sewers and the service area for water,
(4) The development benefits that will accrue to the subdivision,
(5) The sequence of land and utility developments in the vicinity, and
(6) Any other condition it may find pertinent.
(d) General Schedule of Improvements. The developer shall provide and install at his expense the improvements as set forth in the following schedule classified in four districts and as further detailed in subsequent sections:
