(a) The following regulations shall govern the design and layout of lots:
(1) The lot arrangement and design shall be such that all lots shall provide satisfactory building sites, properly related to topography and the character of surrounding development.
(2) All lots shall conform to or exceed the requirements of these regulations or the zoning district in which they are located and the use for which they are intended.
(3) All side lot lines shall be at right angles to street lines and radial to curved street lines, except where the Planning and Zoning Commission determines that a variation to this rule would provide a better layout.
(4) Lots with double frontage shall be avoided except where the Planning and Zoning Commission determines that it is essential to provide separation of residential development from arterial streets. When double frontage lots are created, a common fence, mounding, and landscaping will be required.
(5) No corner lot shall have a width at the building line of less than seventy- five feet, in order to allow proper setback lines from both streets.
(6) Every lot shall abut 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.
(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.
