§ 4. Streets.

(a)

Relation to adjoining street system. Proposed new streets shall extend existing streets or their projections at the same or greater width, but in no case less than the minimum required width, unless variations are deemed necessary by the board, for reasons of topography or design. Where, in the opinion of the board, it is desirable to provide street access to adjoining property, proposed streets shall extend to the boundary of such property.

(b)

Street width. The minimum width of proposed streets measured from lot line to lot line shall be as shown on any major street plan which has been adopted in accordance with law, or if not shown on such plan, not less than 90 feet for officially designated major streets, 50 feet for minor streets with curb and gutter, and 60 feet for minor streets with open drainage ditches.

(c)

Street intersection. Insofar as practical, acute angles at street intersections shall be avoided.

(d)

Dead-end streets. Streets designed to have one end permanently closed (cul-de-sac) shall be provided at the closed end with a turnaround with a minimum right-of-way radius of 50 feet, and a minimum driving surface radius of 35 feet. A "cul-de-sac" shall not be more than 500 feet in length unless approved by the board or its authorized representative for specific reasons of topography or design.

(e)

Street names. Proposed streets obviously in alignment with existing and named streets shall bear names of existing streets. Otherwise, in no case shall the name for the proposed streets duplicate existing street names irrespective of the suffix used.

(f)

Street improvements. Street improvements shall be required as set forth in section 13.
