To establish a common basis for the design and layout of subdivisions and allotments, the following criteria shall be observed in laying out the plat:
(a) Reserve Strips. No plat or map of a proposed street or allotment showing reserve strips controlling access to public ways or showing strips of land which will not prove taxable for special improvements will be approved, provided that such reserve strips may be shown when the control and disposal of land comprising such strips are definitely placed with the Municipality under conditions meeting the approval of the Municipal Engineer, the Law Director and the Planning Commission.
(b) Street Location and Widths. The location and widths of proposed streets shall be such as to fit in with any plan of street development recommended by the Planning Commission or other public authority. Due regard shall be given to existing streets or streets capable of being established in surrounding property, so that streets may be laid out through adjacent or neighboring allotments with reasonable continuity of location and width.
No street shall be less than fifty feet in width, provided that no street shall be less than sixty feet in width where surface drainage is provided by ditches. The Planning Commission may require greater width when in its opinion the greater width is justified or needed.
(c) Length of Block and Street Arrangement. Where practical, intersecting streets shall be provided so that no block shall be longer than 1200 feet. Proposed streets shall follow the contour of the land wherever practical and shall intersect one another at right angles or on radial lines as topography and other limiting factors of good design permit.
(d) Dead-End Streets. No so-called dead-end streets will be approved for dedication, except where conditions make the extension of such street impractical. In such cases, a dead-end street may be approved, provided that adequate turning space for vehicles is placed at the dead-end. Turning spaces shall be of sufficient size to provide for a paved circular roadway at least twenty feet in width, the inside radius of which shall be at least thirty-five feet.
(e) Coterminal Streets. In order that proposed streets may be as nearly coterminal as possible with existing streets in adjoining allotments, due provision shall be made for the continuation of all existing streets which extend to the boundaries of the proposed allotment.
(f) Lots. Lots in the subdivision shall abut on a street and double frontage lots shall be avoided.
(g) Side Lot Lines. Side lot lines shall be approximately at right angles or radial to the right-of-way line of the street on which the lot faces.
(h) Corner Lots. Corner lot frontages shall be platted wider than interior lots to allow for proper setback on both streets.
(i) Intersections. At street intersection property line corners shall be rounded by an arc, the minimum radius of which shall be ten feet.
(j) Minimum Radii. Minimum radii shall be increased within the Commission considers an increase necessary.
