All new lots created by any subdivision of land hereafter proposed shall conform to the minimum requirements of the applicable zoning and form district regulations and shall also conform to the following standards of design:
(A) Lot constraints. Excessive depth in relation to width shall be avoided, with a proportion of five to one normally being considered as a desirable maximum for lot width of 60 feet or greater. Pointed or very irregularly shaped lots and flag lots (except where required for utility connection) shall be avoided where possible. Additional depth shall be required on lots which abut to railroads, have frontage on major streets, or adjoin other conflicting land uses, as specified in applicable form districts. In case of unusual soil conditions or physical factors, including, but not limited to, steep slopes, sinkholes, and/or the location of any portion of the property in the floodplain, which may impair the health and safety of the persons in the neighborhood in which a subdivision may be located, the Commission may prohibit or limit disturbance of environmentally constrained sites as defined in §§ 155.030 through 155.033. Division staff may approve lot shapes which vary from these general guidelines.
(B) Access.
(1) All lots for any uses or structures shall have access to and abut a public or private street for at least 25 feet. No private street shall be used to provide access to more than 20 lots;
(2) All private streets, frontage roads, or ingress/egress easements providing access to residential, commercial, industrial, or other properties or buildings shall be named in accordance with Chapter 6, Part 3;
(3) Any minor plat submitted which creates, extends, widens, or otherwise modifies a private street or submitted for creation or modification of any lot(s) fronting on a private street shall be accompanied by a properly prepared deed of restrictions for maintenance of the street which deed shall have been reviewed and approved by the Planning Commission’s legal counsel (or authorized designee) prior to recording; and
(4) Direct access to major arterial, minor arterials, and collector level roadways from individual single-family lots is prohibited.
(C) Continuation of existing street. Subdivisions shall be designed to ensure that existing public and
private streets which stub into the subject property can be extended through the subject property. For subdivisions creating any lot that abuts or has access to any proposed stub street extension, right-of-way shall be dedicated sufficient to accommodate the extension of the street, and the street shall be constructed in accordance with the requirements of this chapter for constructing public or private roads.
