(2) If all lot sizes in the subdivision are greater than three acres in area the developer may reduce street pavement width for local streets to 24 feet for dedicated or non-dedicated streets, all other standards set forth shall not be waived/reduced. When streets are reduced to 24 feet on-street parking shall be prohibited (this must be part of the covenants and deed restrictions).
(H) The number of access roads required into a subdivision will be based upon the number of lots, sound engineering design and continuity of the county road system. If in the opinion of the Plan Commission staff additional access points are needed it shall make recommendations for additional entrances to the developer and the Plan Commission.

(A) (1) All streets in subdivisions to be dedicated shall be improved with roadway hard surfaces to an overall width in accordance with the minimum dimensions as described in the Table 1 below and be of general design as set forth in the cross-section below.
(2) All streets to be non-dedicated, as approved by the Technical Advisory Committee, shall meet both Table 1 and the cross-section below.
(B) Minimum roadway width dimensions shall be reduced or increased when the Plan Commission determines that such an alteration is required due to terrain or density.
(C) (1) The covenants and restrictions of all subdivisions shall expressly prohibit on-street parking unless the street width is increased above that required by the Table 1 below, by an additional lane width on each side of the road that parking is to be permitted upon.
(2) The surface of the additional lane shall be the same as the surface of the normal travel lane.
Table 1: Minimum Roadway Lane and Shoulder Widths | ||||
Major Residential | Minor Residential | Cul-de-Sac | Non-Dedicated | |
Lane width | 12 ft. | 11 ft. | 10 ft. | 9 ft. |
Shoulder width | 4 ft. | 3 ft. | 2 ft. | 2ft. |
Notes: | ||||
Concrete curb and gutter will be required in place of shoulders when the density of homes exceeds 2 dwellings per acre. | ||||
Table 1 assumes that on-street parking will not be permitted. See § 155.048 for additional requirements to allow on-street parking. |

(2) In estate-type subdivisions consisting solely of lots which are greater than three acres in area, where roadways do not and cannot generate either through traffic or a significant volume of local traffic; and
