§ 23-46. Streets.

(a)

The arrangement, character, extent, width, grade and location of all streets shall conform to the city master thoroughfare plan and shall be considered in their relations to existing and planned streets, to topographical conditions, to public safety and in their appropriate relation to the proposed uses of the land to be served by such streets.

Minor streets shall be laid out such that their use by through traffic will be discouraged.
