12.06.100 Design Standards.
The following standards shall be used in designing driveway approaches to be constructed in the city:
(A) Width of Driveway Approach.
(1) Residential driveway approaches. The width of residential driveway approaches shall conform to the widths as indicated in the following table:
|
Single Family (One-Car Garage) |
10 Feet |
|
Single Family (Two-Car Garage) |
22 Feet |
|
Single Family (Three-Car Garage) |
32 Feet |
|
Duplex (Two, One-Car Garage) |
24 Feet |
|
Duplex (Two, Two-Car Garage) |
44 Feet |
Such widths shall be measured parallel to the centerline of the street at the property line.
(2) Commercial driveway approach. The width of commercial driveway approaches shall not exceed thirty-five feet or be less than twenty-five feet measured parallel to the centerline of the street at the property lines for two-way driveway approaches; provided, however, that commercial property may be allowed to have a driveway approach not exceeding fifty-two feet, if said driveway approach does not exceed twenty percent of the length of the real property abutting the adjacent city street and a four-foot raised median is placed within such driveway approach to divide the entrance and exit lane(s). The minimum width of a one-way driveway shall be sixteen feet.
(3) Industrial driveway approach. The width of industrial driveway approaches shall not exceed sixty-five feet or be less than twenty-five feet measured parallel to the centerline of the street at the property lines for two-way driveway approaches; provided that the minimum width for a one-way driveway shall be sixteen feet.
(B) Angle of Entrance. The angular placement of driveway approaches in residential, commercial and industrial areas may vary from forty-five degrees to ninety degrees inclusive. This limitation includes the entire length of the driveway approach. The angle shall be that made by the centerline of the driveway approach with the centerline of the street or with the tangent to the centerline at the point of intersection if located on a curve.
(C) Corner and Adjacent Property Line Offset.
(1) Residential driveway approaches. When residential driveway approaches are located at or near an intersection, in no case shall the distance from the intersection property corner be less than twenty feet to the near line of the driveway approach, extended to the street curb.
(2) Commercial or industrial driveway approach. When commercial or industrial driveway approaches are located at or near a street intersection, in no case shall the distance from the intersection property corner be less than fifty feet to the near line of the nearest driveway approach, as extended to the street curb or pavement edge.
(3) No commercial driveway approach shall be constructed having a tangent length, between the curb return and the property line extended, of less than twelve and one-half feet.
(D) Safety Islands. The minimum lengths of safety islands between entrances shall be twenty-five feet. Lengths of safety islands is the tangent distance between the turning radii as measured along the surface edge or curb line, measured parallel to the centerline of the street.
(E) Turning Radii.
(1) Residential driveway approaches (residential district) - Turning radii shall not exceed two feet;
(2) Commercial and industrial driveway approaches:
(a) Safety islands shall have a minimum radius of fifteen feet;
(b) Driveway approaches shall have a minimum radius of fifteen feet.
(F) Curb Openings.
(1) Residential driveway approaches. Curb opening for residential driveway approaches shall not exceed the width of the driveway as indicated in Section 12.06.100(A)(1), plus four feet.
(2) Commercial driveway approaches. Curb openings for commercial driveway approaches shall not exceed sixty-five feet. (Ord. 86-55 § 1, 1986; Ord. 759 § 3, 1978.)
