Virginia Administrative Code › Title 24 - TRANSPORTATION AND MOTOR VEHICLES › Agency 30 - DEPARTMENT OF TRANSPORTATION › Chapter 91 - SUBDIVISION STREET REQUIREMENTS › Part II - Specific Provisions › Section 24VAC30-91-110 - Design and agreement requirements

Current through Register Vol. 40, No. 24, July 15, 2024
A. General requirements. Most criteria
				  addressing the design of new subdivision streets can be found in the
				  Subdivision Street Design Guide (24VAC30-91-160 ).
				  However, the following provisions are provided for guidance, particularly in
				  regard to features that require agreements or formal acknowledgements of the
				  governing body before VDOT's acceptance of the street or streets within a
				  subdivision.
When an agreement is required between the local governing
					 body and the department as a prerequisite to the acceptance of a subdivision
					 street, nothing in these requirements shall preclude the local governing body
					 from entering into separate agreements with other entities to fulfill its
					 responsibilities. However, if the provisions are intended to ensure the safety
					 of the public using the street, the department reserves the right to approve
					 the involvement of the other party or parties.
B. Geometric requirements. Geometric
				  requirements for new subdivision streets are established in the Subdivision
				  Street Design Guide of the Road Design Manual (24VAC30-91-160 ). In certain
				  circumstances the Subdivision Street Design Guide (24VAC30-91-160 ) allows reduced
				  pavement widths for curb and gutter sections. Any such reduction must be
				  specifically requested by the governing body in writing and be approved by the
				  resident engineer. Sufficient off-street parking must be provided by the local
				  governing body as indicated in the Subdivision Street Design Guide
				  (24VAC30-91-160 ) to accommodate
				  any request for reduced pavement widths. However, no special request from the
				  local governing body shall be required in the event the department has approved
				  a design standard for use throughout that county that includes street width
				  reductions for a specific type of subdivision, such as a Neotraditional
				  subdivision.
C. Turn lanes. Left or
				  right turn lanes shall be provided at intersections when the department
				  determines that projected turning movements warrant their installation. These
				  facilities shall be designed in accordance with the Subdivision Street Design
				  Guide (24VAC30-91-160 ) and, if
				  necessary, additional right-of-way shall be provided to accommodate these
				  facilities.
D. Pavement structure.
1. Pavement design. The pavement structure
				  for new subdivision streets shall be in accordance with the Pavement Design
				  Guide (24VAC30-91-160 ), including any
				  prescribed underdrains. Prior to construction of the pavement sub-base and
				  finish courses, the resident engineer shall approve the proposed pavement
				  design.
2. Special pavement
				  surfaces. The resident engineer may approve special pavement surfaces, such as
				  the use of stamped pavement or the use of paving blocks or bricks. However, if
				  the pavement design is a type not addressed by the Pavement Design Guide
				  (24VAC30-91-160 ) or otherwise not
				  in general use by the department, an agreement shall be provided by the
				  governing body that addresses the future maintenance of such
				  pavement.
3. Pavement additions to
				  existing streets. When an existing VDOT maintained roadway is to be widened to
				  accommodate additional lanes or the addition of turn lanes, the necessary
				  pavement design shall be obtained from the resident engineer and the entire
				  surface of the roadway (old and new portions) shall be overlaid and re-striped
				  as required by the resident engineer.
