(a) Conformity with Official Maps and Plans. The arrangements, type, extent, width, grade and location of all streets shall conform with the Map of the City, the Comprehensive Plan of the City and any other official City, regional, County or State Plan which may be prepared, adopted and/or filed as prescribed by law.
(b) Relation to Topography. Streets shall be logically related to the topography so as to produce usable lots at reasonable grades.
(c) Relation to Proposed Use. Streets shall be in appropriate relationship to the proposed land uses served by such streets.
(d) Traffic Movement. Local streets shall be so laid out as to discourage through traffic but provisions for street connections into and from adjacent areas shall be generally required.
(e) Continuance of Streets. Provisions shall be made for continuing or extending any existing streets or adjoining subdivisions or land where such extension may be necessary for public service or convenience and opportunities shall be provided for extending streets beyond the boundaries of any subdivision where such extension may be required for public service or convenience.
(f) Reverse Frontage. Where a subdivision abuts or contains an existing or proposed arterial street, the Commission may require reverse frontage, screening or no access which shall provide protection for abutting properties, reduce the number of intersections and separate local and through traffic.
(g) Half Streets. Half streets shall be prohibited except to complete an existing half street.
(h) Dead End Streets and Cul-De-Sac's. A dead end street shall be prohibited, except as a stub to permit future street extension into adjoining tracts or when designed as a cul-de-sac. Dead end streets, designed to be so permanently, shall not be longer than 500 feet and shall be provided at the closed end with a turnaround or cul-de-sac having no island thereon, having a roadway diameter of at least eighty feet and a right-of-way diameter of at least 100 feet.
(i) Subdivision Borders on a Railroad or Limited Access Highway. Where a subdivision borders on or contains a railroad right-of-way or limited access highway right-of-way, there may be required a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts, or for business or industrial purposes in appropriate districts. Such districts shall also be determined with due regard for the requirements of approach, grades and future grade separations.
(j) Alleys. Alleys are not permitted in residential districts under the Moundsville Zoning Ordinance. However, alleys are permitted in commercial and industrial districts unless waived by the Commission. Alley design regulations are as follows:
(1) Minimum cartway width of thirty feet; and
(2) Maximum alley grade shall be ten percent (10%).
 |
(k) Private Streets. Private streets shall not be approved nor shall improvements be approved for private streets.
(l) Street Widths. Minimum street widths shall be as follows:
(1) Street width chart:
Type of Street | Type of Development | Cartway Width (Feet) | Right-of-Way Width (Feet) |
Local | Single-family lots | 301 | 50 |
Collector | Single, double, multi-family, commercial or industrial lots | 402 | 60 |
Arterial | All types | As prescribed by the West Virginia Department of Highways | |
1 One, eight-foot parking lane
2 Two, eight-foot parking lanes
(2) Any street or way already established shall be continued at not less than its existing width and not less than the above street width requirements.
(3) Any street or way recorded yet not already established, shall be continued at not less than its width as planned and not less than the above street width requirements.
(4) Where a subdivision abuts or contains an existing street of insufficient right-of-way width as required above, additional right-of-way width in conformance with the above street width requirements shall be required.
(5) In cases where a new subdivision is planned to join the street or road system on an existing subdivision, the above minimum requirements shall apply except where the existing streets or roads and rights-of-way are larger than required. In this event, the Commission may require that the new streets or roads and right-of-way be as large as the existing. Private covenants may apply if their provisions are in excess of these Land Subdivision Regulations.
(m) Street Intersections.
(1) All curbs at intersections shall be rounded by a minimum radius of:
A. Collector or arterial streets and roads - twenty-five feet;
B. Local Streets - twenty feet; and
C. Or such greater radius as is deemed necessary by the Commission.
(2) When any street or road intersection shall involve earth banks or vegetation, existing or to be planted inside any corner lot that would create a traffic hazard by limiting visibility, the subdivider shall cut such ground and/or vegetation to a height of three and one-half feet above the finished paved area at the center of the right-of-way, to provide a sight line of 100 feet along the centerline of a collector street or arterial road and a local street intersect, each shall retain their respective footage requirements along the centerline to form the clear sight triangle.
(3) Where the grade of any street at the approach to an intersection exceeds five percent (5%), a leveling area shall be provided with a transitional grade not to exceed two percent (2%) for a distance of fifty feet from the nearest right-of-way line of the intersection.
(4) Intersections of more than two streets shall be the most complex intersections permitted.
(5) Streets shall be laid out so as to intersect as nearly as possible at right angles. No street shall intersect another at an angle of less than sixty degrees.
(6) Street jogs, offsets or dog-legged streets entering opposite sides of another street shall have no less than 150 feet between their centerlines.
(n) Street Grades.
(1) Maximum allowable centerline grades:
A. Arterial roads - five percent (5%);
B. Collector streets - six percent (6%); and
C. Local streets - twelve percent (12%).
Grades in excess of twelve percent (12%) may be approved by the Commission where it is clear that no traffic hazard is or shall be created thereby.
(2) Minimum allowable centerline grades on all streets shall not be less than one-half of one percent (.50%)
(o) Street Alignment.
(1) Vertical curves shall be installed at all street grade changes exceeding one percent (1%).
(2) To ensure adequate sight distance, minimum centerline radius for a horizontal curve shall be as follows:
A. Arterial roads - as prescribed by the West Virginia Department of Highways;
B. Collector streets - 300 feet; and
C. Local streets - 150 feet.
(3) Reverse curves shall have a minimum tangent between them of:
A. Arterial roads - as prescribed by the West Virginia Department of Highways;
B. Collector streets - 150 feet; and
C. Local streets - 100 feet.
