(A) Continuation of existing streets. Proposed streets shall, as near as practicable, provide for the continuation, connection, or projection of streets in surrounding areas, or may conform to a plan as may have been approved by the County Engineer.
(B) Private streets. Private streets shall be prohibited. All streets within a platted subdivision must be dedicated to public use.
(C) Circulation. The street pattern shall provide ease of circulation within the subdivision, but the local streets therein shall be so laid out that their use by through traffic will be discouraged. Insofar as practical, the street arrangement should provide proper access to schools, playgrounds, transportation, and other community features. New street openings shall generally be prohibited within 600 feet of any major intersection or crossing such as those formed by a railroad and a highway, two or more highways, or from the head of any major bridge, grade separation structure, or like facilities, as measured along the centerline from the intersection or from such structures.
(D) Topographical and cultural features. In sloping terrain, streets shall generally run parallel to the contour of the land or preferably cross at a slight angle therewith. The general objectives are to avoid steep roadway grades, heavy concentrations of storm surface runoff; abnormal differentials in building elevations at opposite sides of the street, and excessive grading operations.
(E) Portion of tract. Where the plat to be submitted includes only a part of the tract owned by the subdivider, the county requires topography and a sketch layout of the future street system on the un-subdivided tract at a later date.
(F) Intersections. The angle of intersection between a minor street and a major street should not vary by more than ten degrees from a right angle. All other roads should intersect each other as near to a right angle as possible, and no intersection of roads at angles of less than 70 degrees shall be permitted.
(G) Street jogs. Street jogs shall be avoided whenever possible. However, where permitted, the minimum centerline offset distance between roads entering a common right-of-way from opposite sides will be 150 feet.
(1) Half street. Half streets shall be prohibited.
(2) Reserve strips. Reserve strips controlling access to roads and streets shall not be permitted.
(3) Dead-end streets. Dead-end or stub-end streets are prohibited. However, where it is necessary to provide circulation to undeveloped property adjacent to the boundaries of the proposed subdivision, a temporary cul-de-sac with not less than an 80-foot turnaround easement with not less than a 60-foot turnaround pavement with not less than six- inch base course gravel with A-2 treatment shall be provided within the subdivision and adjacent to its limit for what would otherwise be a stub-end street. Provision will be made by the subdivider that when the right-of-way is extended into the adjacent property, that portion of the turnaround in excess of the right-of-way width will revert to the adjacent property owner or owners, and curbs and gutters will be provided.
(4) Cul-de-sac. A cul-de-sac, designed to be so permanently, shall not be longer than 500 feet and shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 100 feet and a street property line diameter of at least 120 feet. No cul-de-sac may intersect with another cul-de-sac.
(5) Alleys. Alleys in residential developments shall be prohibited. Service roads shall be required in commercial and industrial developments, except where other provisions for suitable access and off-roadway loading and unloading are assured. Alleys may be provided at the rear of all lots or tracts intended for multiple-family building use; however, they will not be encouraged.
(6) Right-of-way. In the case of the extension of an existing adjoining right-of-way, having a width less than the minimum requirement, the Subdivision and Planning Committee may approve the extension thereof at the same width.
