(A) Conformity to comprehensive plan and/or official map. Whenever a tract of land to be subdivided or resubdivided includes any part of a proposed arterial or collector street as designated on the comprehensive plan and/or the official map, such street right-of-way shall be platted by the subdivider in the location so designated and at the width indicated in these regulations.
(B) Street extension.
(1) Existing streets. The arrangement of streets in new subdivisions shall make provisions for the proper continuation of existing streets in adjoining areas.
(2) Adjacent property. Where adjoining areas are not subdivided and are appropriate for future subdivision, arrangement of streets in new subdivisions shall make provisions for the proper projection of streets to that adjoining area in a manner which shall provide for the practical development of the adjacent property, permit a feasible extension of the street, and be in general conformity with a plan for the most advantageous development of the entire neighborhood.
(3) Half streets. Dedication of one-half of the rights-of-way (half streets) for streets proposed along the boundaries by land to be subdivided, shall be prohibited.
(4) Dedication of one-foot strip next to undeveloped or unplatted land. A one-foot strip of land shall be required along the boundary line of subdivision wherever the right-of-way line of a street forms such boundary next to undeveloped land. All one foot strips of land located on dedicated rights-of- way shall be dedicated to the city for non-road purposes.
(C) Street classification and function.
(1) Arterial streets. Arterial streets should be planned for continuation of movement of fast traffic between points of heavy traffic generation and from one section of the community or communities to another. Such arterial streets should traverse the entire community or communities and should be spaced approximately one mile apart. Arterial streets should not bisect neighborhoods but should act as boundaries between them. Abutting properties should not face onto the roadway unless separated from it by a frontage or service road.
(2) Collector streets. Collector streets should be designed to provide a traffic route from local streets to arterial streets. These streets should be designed to carry traffic which has an origin or destination within the neighborhood and should be designed to inhibit through traffic.
(3) Local streets. Local streets shall provide direct and full access to each lot and shall be laid out so that their use by through traffic will be discouraged. Local streets intersecting with arterial streets should be discouraged.
(4) Frontage roads. Frontage roads may be required along an existing or proposed arterial street to provide access to lots along such streets.
(5) Alleys. Where alleys are to be provided (e.g., in the case of certain commercial development), they shall be designed to provide only secondary access.
(D) Street rights-of-way.
(1) Widths and grades of new streets. Street right-of-way widths and grades shall conform to the following minimum requirements:
TABLE 1
STREET RIGHTS-OF-WAY WIDTH AND GRADE REQUIREMENTS
STREET RIGHTS-OF-WAY WIDTH AND GRADE REQUIREMENTS
* Arterial streets shall be based on current design standards and other pertinent requirements of the Kentucky Department of Highways.
(2) Existing streets. Subdivisions platted along existing streets shall dedicate additional right-of-way, if necessary, to meet the minimum street width requirements set forth in Section 6.0 (D) (1) of these requirements. Such dedication shall be in accordance with the following:
(a) At least the minimum right-of-way width shall be dedicated where the subdivision is on both sides of an existing street.
(b) When the subdivision is located on only one side of an existing street, one- half of the required width, measured from the centerline of the right-of-way, shall be dedicated. However, in no case shall the owner or owners of such property be forced to dedicate from their land more than one- half of the required rights-of-way width.
(E) Curves and sight distance criteria.
(1) Horizontal curve. Where there is a change in the alignment of a street along the centerline, a curve with a radius adequate to insure safe sight distance shall be made. The minimum radii of curves shall be:
STREET TYPE | MINIMUM CURVE RADIUS |
Arterial | * |
Collector | 300 |
Local | 100 |
(2) Sight distance. A minimum sight distance of 200 feet shall be provided for local streets and 275 feet for collector streets.*
(3) Reverse curves. A tangent at least 100 feet shall be provided between reverse curves for local streets and 200 feet for collector streets.*
(4) Vertical curves. The minimum vertical curve length required shall be calculated by multiplying the algebraic difference in grades, times a "K" factor. Rounded "K" factors for the three street classification types are as follows:*
Local
K=20 for both crest and sag curves
Collector
K=35 for both crest and sag curves
*Arterial streets shall be based on current design standards and other pertinent requirements of the Kentucky Department of Highways.
(F) Cul-de-sacs and dead-end streets.
(1) Dead-end streets designed to be dead-end permanently, shall not be longer than 600 feet, unless local topographic or other physical conditions are such as to render these provisions impracticable, and shall be provided with a turning circle having an outside pavement diameter (curb face to curb face) of at least 80 feet and a street property line diameter of at least 100 feet. If such street is of a temporary nature and a further extension into adjacent land is anticipated, then said turning circle beyond normal street width shall be in the nature of a dedication of the premises included in said turning circle, but beyond the boundaries of the streets proper. Such dedications shall be vacated to abutting property owners when said dead-end street is legally extended into adjacent land. If such dead-end street extends only one lot depth past a street intersection, no temporary turning circle will be required.
(2) In the case of dead-end streets extending to the boundary of the property, a one-foot strip within the dedicated right-of-way shall be dedicated to the city for non-road purposes. Such dedication or restriction shall be vacated or removed when the dead-end street is properly extended.
(G) Street names.
(1) Duplication. The name of a new street shall not duplicate existing or platted street names in Campbell County, or approximate such names in spelling, or sound or pronunciation, or by the use of alternate suffixes such as "Lane", "Way", "Drive", "Court", "Avenue", or "Street".
(2) Continuation of streets. New street names shall bear the same name of any continuation of, or when in alignment with, an existing or platted street.
(3) Approval of street names. All street names shall be approved by the Planning Commission, or its duly authorized representative, before approval of the final plat.
(H) Alleys.
(1) Alleys shall be prohibited in residential zoning districts.
(2) In commercial and industrial areas, adequate alleys shall be provided where the design requires. Alleys shall not serve as part of the required off-street parking, loading and/or unloading space required by the zoning ordinance.
(I) Private streets. New private streets or alleys shall not be created or extended and existing ones shall, whenever practicable, be dedicated to the public.
