Division 2.  Streets and Alleys

 

Sec. 14-409 Coordination of streets.

 

Public streets shall be coordinated as follows:

 

A.   All public streets within a subdivision shall coordinate as to location, width, grades and drainage with other public streets, as follows: (i) by coordinating with existing or planned streets within the general area of the subdivision, including but not limited to existing or future adjacent subdivisions, or subdivisions contiguous to such adjacent subdivisions; (ii) by continuing the public streets to planned, existing, or platted streets into adjoining areas by dedication or reservation of right of way adequate to accommodate continuation of the streets; and (iii) by constructing the public streets to the abutting property line to provide vehicular and pedestrian interconnections to future development on adjoining lands.  The arrangement of all streets shall provide adequate access to adjoining parcels where necessary to provide for the orderly development of the county.     

 

     B.   The requirements of subsection (A) may be waived by the agent as provided in section 14-224.1.  In reviewing a waiver request, the agent may allow a public street not to be extended to the abutting property line if it is determined that extending the street would require offsite easements, disturb stream buffers, or would not otherwise serve a present public purpose.  In such a case: (i) the public street shall be constructed past the point at which the primary structures on the adjoining lots would rely on the finished grade for landscaping and other improvements, but in no case less than thirty (30) feet beyond the curb line or ditch line on the adjoining lot; (ii) the subdivider shall dedicate the required right of way to the abutting property line, along with all easements required to allow the street connection to be constructed in the future; the required easements shall prohibit any improvements being established therein; and (iii) the agent may require that the subdivider install and maintain a sign at the end of the

constructed portion of the street stating that the street is a future through street; the agent may require that the subdivider maintain the sign until the county grants final approval of extending the street to the abutting property.

STA Language – 50 lot rule  

 

Existing -- H.     Principal means of access.  The principal means of access to a subdivision shall conform, in the case of a public street, to Virginia Department of Transportation standards, or, in the case of a private road, to the standards of the county as set forth in section 14-514, throughout it length, including any distance between the boundary of the subdivision and any existing public street.  If the subdivision will result in the potential development of fifty (50) or more dwelling units, the subdivision shall have more than one principal means of access from an existing public street.  If discharge water of a one hundred year storm could reasonably be anticipated to inundate, block, destroy or otherwise obstruct a principal means of access to a residential subdivision, the following shall also apply:

 

Proposed – see F. below.

 

 

Sec. 14-410 Standards for all streets and alleys.

    

The following minimum design standards shall apply to all streets and alleys within a subdivision:

 

     A.  Layout.  Each street shall be configured, to the extent practicable, to conform to the natural topography, to minimize the disturbance of critical slopes and natural drainage areas,

and to provide vehicular and pedestrian interconnections within the subdivision and existing or future development on adjoining lands.

 

     B.  Angle of intersection.  An angle of intersection of not less than eighty (80) degrees is acceptable; however, a perpendicular intersection, where practical, is preferred.  The county engineer may grant an exception to this requirement for a private street in accord with the Virginia Department of Transportation standards for public streets.

 

C.  Temporary turnarounds.  Streets more than three hundred (300) feet in length from an intersection, or proposed to serve more than four (4) dwelling units that terminate

temporarily shall be provided with a temporary turnaround meeting American Association of State Highway and Transportation Officials minimum standards.  The temporary turnaround

shall be extended to the abutting property line if the agent determines the extension is necessary to continue the street to the abutting property.  The temporary turnaround shall exist until the street extensions are accepted into the secondary system of state highways.

 

     D.  Alleys.  Alleys with a right-of-way or easement width of not less than twenty (20) feet may be provided in the rear or side of all commercial, industrial, and residential lots.  The design specifications shall be determined by the county engineer, subject to the following: (1) the alley design shall allow emergency services vehicles such as police cars and ambulances to use the alley; and (2) an alley need not be designed to accommodate the largest emergency services vehicles, except that if firetrucks do not have adequate access to one or more lots from a street, the county engineer shall require that the alley be designed to accommodate firetrucks.  The agent may authorize an alley to be established with a right-of-way or easement width of less than twenty (20) feet if the director determines that, based upon the recommendation of the county engineer, the proposed design incorporates features that assure public safety and welfare.  The county engineer shall consider the provision of adequate access to required onsite parking and/or garages, unimpeded vehicular circulation along the alley, an adequate clear zone along the alley, and other safety issues deemed appropriate for the conditions.  Alley rights-of-way may either be established as privately held fee simple interests or as privately held easements.

 

     E.  Reserved or spite strips.  Reserved or spite strips restricting access to an existing or future street or alley shall not be permitted; provided that nothing herein shall prohibit areas

for scenic planting and landscaping where adequate access to the adjoining lands is otherwise available.

 

     F.  Principal means of access.  The principal means of access to a subdivision shall conform, in the case of a public street, to Virginia Department of Transportation standards, or, in the case of a private street, to the standards of the county as set forth in section 14-412, throughout the street’s length, including any distance between the boundary of the subdivision and any existing public street.  If discharge water of a one hundred (100) year storm could

reasonably be anticipated to inundate, block, destroy or otherwise obstruct a principal means of access to a residential subdivision, the following shall also apply:

 

          1.  The principal means of access shall be designed and constructed so as to provide unobstructed access at the time of flooding, subject to the requirements of section 30.3, flood hazard overlay district, of the zoning ordinance; and/or

 

          2.  An alternative means of access which is not subject to inundation, blockage, destruction or obstruction, and which is accessible from each lot within the subdivision shall be constructed.
