To ensure that owners will have sufficient land upon which to construct a structure that is flood-free, compliance with floodway widths and the 100-year flood elevations contained within the Town's Flood Insurance Study (FIS) is mandatory. The Town Engineer may require the applicant to provide elevation and flood profiles, based on a 100-year floodplain, sufficient to demonstrate the land to be completely free of the danger of floodwater at an elevation of at least one foot below any probable floor level of any structure for human occupancy.

Except as provided herein the Town Engineer shall not approve streets subject to inundation or flooding by water. All streets must be adequately located above the line of flood elevation to prevent isolation of areas by flood. Drainage facilities in local, collector, and cul-de-sac streets shall be designed to handle a storm with an expected return period of once in every 10 years. Drainage facilities in arterial streets shall be designed to handle a storm with a twenty-five-year return period.

All streets in the proposed subdivision shall be designed and constructed by the subdivider in accordance with the minimum requirements of this chapter, at no cost to the locality.

Unless otherwise provided herein or in this chapter, there shall be no private streets platted in any subdivision. Every subdivided property shall be served from a publicly dedicated street constructed to the standards of this Code and accepted and maintained by the Town of Abingdon.

Street improvements shall be made in compliance with the latest edition of Road and Bridge Specifications of the Virginia Department of Transportation, where applicable.

No development shall be approved if such development, at ultimate build-out, will result in or increase traffic on the arterial or collector street to which it is connected, so that the street does not function at an average daily traffic Level of Service C or better, or a peak traffic Level D, as described in "A Policy on Geometric Design of Highways and Streets," latest edition, published by the American Association of State Highway and Transportation Officials. The applicant may propose and construct approved traffic mitigation measures to provide adequate roadway capacity for the proposed development.

Local streets shall approach the major or collector streets at an angle of not less than 80°, unless the Town Council upon recommendation of the Town Engineer, shall approve a lesser angle of approach for reasons of contour, terrain, or matching of existing patterns. Whenever possible, streets should intersect at a right angle. Where a deflection angle of more than 2° in the alignment of a street occurs, a curve of reasonably long radius shall be introduced.

On streets 60 feet or more in width the center-line radius of curvature shall not be less than 300 feet, on other streets not less than 100 feet.

Face of curb radii at intersections shall generally be not less than 30 feet for collector streets nor less than 20 feet for local streets. Face of curb radii at arterial street intersections shall be as determined by the Town Engineer.

The minimum width of existing and proposed streets, measured from lot line to lot line, shall be as shown on the street designation map incorporated in Addendum A. The minimum width of streets, which do not appear on said map, shall be classified according to potential traffic load determined by the public works department as follows:

Whenever subdivided property abuts an existing half street, the remainder of the street shall be dedicated to make the right-of-way on the half street abutting the subdivision comply with Section 10-2-6(c)(1) above.

Streets shall be graded to the cross section and profile approved by the Town Council.

Streets shall be surfaced to the following minimum pavement widths:

On streets that are required to have a right-of-way width of 60 feet or more, grades shall not exceed 6%.

On streets and alleys permitted to have a right-of-way width of less than 60 feet, grades shall not exceed 12%.

All streets and alleys, including those within platted areas which are dedicated for public uses, shall be graded to the full right-of-way width unless the Town Council permits a lesser graded width. In all cases the center line of the roadway shall coincide with the center line of the dedicated right-of-way.

Local terminal streets (cul-de-sac), designed to have one end permanently closed, shall not be longer than 1,000 feet, to the beginning of the turnaround.

Each cul-de-sac must be terminated by a turnaround having a property line diameter of at least 100 feet.

If surface water drains into the turnaround, due to the grade of the street, necessary storm drainage facilities, and drainage easements shall be provided.

The minimum face of curb radius shall be 42 feet.

Alleys shall be provided in business and industrial districts, except that the Town Council may waive this requirement where other definite and assured provision is made for service access, such as off-street loading and unloading, and parking consistent with and adequate for the uses proposed.

While not required, the Town Council may recommend alleys be provided to serve residential properties where such alleys are considered necessary. In any case, dead-end alleys should be avoided where possible, but, if unavoidable, shall be provided with adequate turn-around facilities as recommended by the Town Council.

All roadways shall be paved with bituminous material, in accordance with the requirements of the Town of Abingdon Department of Public Works for acceptance by that Department and as approved by the Town Council after receiving the report and recommendation of the Town Manager. The subdivider shall be responsible for bringing roadways up to standard for initial acceptance by the Abingdon Department of Public Works.

Curbs and gutters shall be installed on both sides of all streets and shall conform to the Virginia Department of Highways and Transportation Standard CG-6. When in the opinion of the Town Engineer curbing alone will satisfy the needs of the subdivision, curbs conforming to Standard CG-2 shall be constructed on both sides of all streets. Curb depth below surface of pavement may be modified if so recommended by the Director of Public Works.

Sidewalks of concrete or other approved material with a minimum width of five feet and a minimum thickness of four inches shall be installed on both sides of all streets when the adjacent property has an existing sidewalk or when in compliance with the Comprehensive Plan; provided, however, that where warranted, the Town Council may waive these requirements.

Where sidewalks and/or curbs and gutters are installed, drive entrances shall be constructed conforming to Virginia Department of Transportation Standard CG-9B or CG-9D as determined by the Town of Abingdon prior to construction. Where no sidewalk is constructed, an apron two feet wide shall be constructed conforming to Section C-C of CG-9B and Section A-A of CG-9D.

Unless the Town Council allows an exception, proposed streets which are obviously in alignment with others already existing and named, shall bear the names of the existing streets.

In no case shall the name of the proposed streets duplicate existing street names regardless of the use of the suffix street, avenue, boulevard, drive, way, place, or court.

Street names shall be indicated on the preliminary and final plats and shall be approved by the Town Council.

Names of existing streets shall not be changed except by the approval of the Town Council. House numbers (911 addresses) shall be assigned by the Town of Abingdon.

Whenever an area is divided into lots and cannot be further divided, and the Town Council requires provisions for street access to adjoining property, proposed streets shall be extended by dedication and construction to the boundary of such property. Such dead-end streets shall be provided with a temporary turnaround.

Whenever an area is divided into lots, containing one or more acres, and such lots can be resubdivided into smaller building lots, consideration must be given to the highway, street and lot arrangement of the original subdivision so that additional local streets can be opened which will permit a logical arrangement of smaller lots. Easements, providing for the future opening and extension of such streets may, at the discretion of the Town Council, be made a requirement of the plat.

Half streets along the boundary of land proposed for subdivision are not permitted.

Streetlights shall be provided on all collector, arterial, and local streets within or contiguous to a subdivision. The streetlight layout shall be in accordance with the VDOT Subdivision Street Guide (24VAC-30-91-160). The installation cost shall be paid by the subdivider. Each streetlight shall:

Drainage plans.

Soil erosion and sediment control plans.

Street plans including width of roadways, cross sections and profiles with present and proposed grades and street intersection elevations and all drainage and utility features required, and other necessary data. The cross sections shall be taken and withdrawn at intervals of not more than 50 feet along the center line, unless otherwise required by the Town of Abingdon, and shall extend out to the sides to that point where the proposed grade intersects the existing grade. In no case shall these cross sections be extended less than the full width of the right-of-way.

Natural gas, water supply, and sewage disposal plans including drainage courses, existing sewers, water and gas mains and culverts, and other underground structures, showing pipe sizes, invert elevations, and grades.
