(a) 
All driveway approaches shall be a minimum of six (6) inches thick for residential, and eight (8) inches thick for commercial, including the sidewalk area. Approved reinforcing steel can be used if so desired, or if called for in the proposal. The concrete will be poured in one (1) course, but a “dust coat” of dry cement (one part) and sand (two (2) parts) will be permitted if so desired. The maximum width of a driveway for residential purposes will be twenty-five (25) feet for a double driveway and fifteen (15) feet for a single driveway.

On type B or type C major thoroughfares, in other than agriculturally or residentially zoned areas, no “head in” parking immediately off the street will be allowed where any maneuvering in or encroachment of public right-of-way is required to make use of the space. If this type of parking is proposed, and the city engineer determines that it meets the above criteria, the maximum width of such entrance will not be limited to forty-five (45) feet, but rather be determined by the surrounding conditions.
(c) 
A site plan, submitted by the party requesting the permit, showing the location and elevation of all driveways (residential and commercial) must be approved by the city engineer or his representative prior to the issuance of permit.

The thickness of the gutter section shall be six (6) inches and the thickness of the curb section shall be six (6) inches from the point where the gutter line tangent intersects the curb face tangent to the back of the curb section. The curb face shall have a one-inch batter, so that the top of the curb shall measure five (5) inches from the point where the curb face tangent meets the top plane of the curb to the back of the curb section. The height of the curb section shall be twelve (12) inches at the back. The face of the curb section shall have an arc at the top, the radius of which is two and one-half (2-1/2) inches, and an arc with a three-inch radius shall be constructed at the point where the curb face meets the top of the gutter section. The bottom of the curb and gutter section shall be constructed perpendicular to the bottom of the curb section for a distance of six (6) inches and the remaining portion of the bottom of such section shall be tilted so that the lip of the gutter section will be one (1) inch higher than the point where the gutter line tangent intersects the curb face tangent. The overall width of the curb and gutter section shall be twenty-four (24) inches. If the gutter is poured separately from driveways, the overall width will also be twenty-four (24) inches. If curbs are poured separately, the overall width will be eight (8) inches at the base and six (6) inches at the top.

Any person aggrieved or affected by any decision of any administrative officer of the city acting under and by virtue of the provisions of this division may appeal to the city council, by filing with the officer from whom the appeal is taken, and with the city clerk, a notice of appeal, in writing, specifying the grounds thereof. Such appeal shall stay all proceedings in the furtherance of the action appealed from, until the next regular meeting of the city council, unless such appeal is taken up for consideration by the council before such regular meeting. When, in its judgment, the city council decides that the appeal involves an application for special exception to the regulations of this division, and it is further of the opinion that the public convenience and welfare will not be substantially or permanently injured, it shall, subject to appropriate conditions and safeguards, authorize special exceptions to the regulations and provisions of this division.
