(A) The street layout shall be in conformity with a plan for the most advantageous development of the entire neighboring area.
(B) All proposed streets shall be in alignment with existing planned or platted streets with which they are to connect and shall be consistent with the following:
(1) Street names.
(a) Proposed streets which are obviously in alignment with other existing streets shall bear the name of the existing street.
(b) In no case shall the name of a proposed street duplicate or be phonetically similar to existing street names, irrespective of the use of prefix or suffix.
(c) The County Engineer's office shall approve the assignment of all new street names to avoid confusion.
(2) Street signs.
(a) The subdivider shall install required traffic control and street name signs.
(b) The location and design of the signs shall be approved by the County Engineer's office.
(c) Street name signs shall be installed at all intersections within a subdivision.
(3) Street layout.
(a) The street layout may include minor streets of considerable continuity, approximately parallel to and on each side of each major thoroughfare to avoid lots fronting on the thoroughfares.
(b) Proposed streets shall be adjusted to the contour of the land so as to produce reasonable gradients.
(c) Certain proposed streets shall be extended to the boundary line of the tract to be subdivided so as to provide for normal circulation of traffic within the vicinity. Wherever there exists a dedicated or platted street abutting the tract to be subdivided, the developer shall extend the street to an intersecting street, or shall terminate the street in a permanent type turnaround, the radius of which shall be as determined and approved by the County Engineer.
(d) Whenever there exists a dedicated or platted half-street or alley adjacent to the tract to be subdivided and approved by the Planning Commission, the other half shall be platted. In no case shall a new half street be permitted.
(e) Cul-de-sac streets may be planned where conditions permit their use, and in no instance shall be designed to accommodate more than 20 lots in a residential subdivision or more than ten (10) lots in a commercial or industrial subdivision.
(f) Alleys may be required where appropriate in commercial and industrial areas. Except where justified by extreme conditions, alleys shall not be approved in residential subdivisions.
(g) All streets and alleys shall intersect at right angles (90 degrees) or as nearly thereto as possible. No street shall intersect any other street at an angle of less than 75 degrees (angle of intersection to be measured at the junction of the street center lines).
1. The center lines of not more than two (2) streets shall intersect at any one (1) point.
2. Street jogs are to be avoided, but, where unavoidable, street jogs at intersections shall have a center line off-set of not less than 150 feet.
3. A triangular area formed by the intersection of the street right-of-way lines and a distance 35 feet back along the lines connected by a straight line at the points thus determined, must be kept clear of all vegetation, wall or structure for a height of between two and one-half (2-1/2) feet and then ten (10) feet for vision of motorists, pedestrians, and other users.
(h) All specifications regarding the installation of county roads within a subdivision shall be determined by the County Engineer's office which shall approve sub-base and base materials and construction practice, pavement materials, pavement and right-of-way widths, grades, vertical and horizontal curves, and any other design requirements for roads not specifically noted in these regulations. All roads shall be constructed equal to or better than the South Carolina Department of Highways and Public Transportation specifications.
(i) Wherever a tract to be subdivided is proposed to ingress and egress from and onto an existing road of exceptional vertical or horizontal fluctuation, the County Engineer's office, taking into account traffic volume and speed shall determine the appropriate point or points for ingress and egress.
