The following regulations shall govern the design and layout of lots:
(l) The lot arrangement and design shall be such that all lots shall provide satisfactory building sits, properly related to topography and the character of the surrounding development.
(2) All lots within the city shall conform to or exceed the zoning district requirements in which they are located and the use for which they are intended.
(3) All side lot lines shall be at approximate right angles to street lines and radial to curved street lines except where the Commission determines that a variation to this rule would provide a better layout.
(4) Lots with double frontage shall be avoided except, where the Commission determines that it is essential to provide separation of residential development from arterial streets.
(5) No corner lot shall have a width at the building line of less than seventy feet.
(6) Each lot shall abut on a public street and narrow reserve strips of land which are intended by the owner of a plat to prevent access to streets or the extension of sewer, water or storm drain lines from one plat to another are prohibited. Buffer lots are permitted. See definitions.
(7) No lots shall be formed or building permitted at the closed end of a temporary or stub-end street which would tend to prevent the appropriate extension of such road or street into an adjoining territory.
