Board of Supervisors Transportation Committee: Next Steps for Urban Street Standards

  1. 1. County of Fairfax, Virginia Next Steps for Urban Street Standards Board of Supervisors Transportation Committee June 25, 2013 Department of Transportation 1
  2. 2. County of Fairfax, Virginia Purpose • The purpose is to develop a set of urban transportation design standards that can be utilized anywhere in Fairfax County, specifically it’s urban activity centers and revitalization areas. • The new standards are based on a context-sensitive design approach that establishes a walkable low-speed urban roadway environment. • The new standards will create a flexible platform that will allow for implementation of the County’s comprehensive plan, particularly the recommended grid of streets, and urban streetscape zones. • The new standards will focus on urban design elements that allow for construction of “complete” or multi-modal streets that effectively accommodate all modes of transportation, and reduce the number of design waivers and exceptions ordinarily required from VDOT. Department of Transportation 2
  3. 3. County of Fairfax, Virginia Primary Reference Sources • Fairfax County Comprehensive Plan. • Institute of Transportation Engineers (ITE) recommended practice: Designing Walkable Urban Thoroughfares: A Context Sensitive Approach, 2010. • American Association of State Highway and Transportation Officials (AASHTO), A Policy on Geometric Design of Highways and Streets, 2004; low speed urban street design. • Road Design Manual (RDM), VDOT. • Access Management Design Standards for Entrances and Intersections, VDOT. • Multi-modal System Design Guidelines, Department of Rail and Public Transportation (DRPT). Department of Transportation 3
  4. 4. County of Fairfax, Virginia Background • In April 2010, the General Assembly of Virginia enacted HB 222 (Watts), “Design standards for state secondary highway system components,” which required VDOT and Department of Rail and Public Transportation (DRPT), to work in conjunction with Fairfax County to develop new context sensitive, urban design standards for the county. • On September 13, 2011, the Board adopted Transportation Design Standards and a Memorandum of Agreement with VDOT (MOA), for the Tysons Corner Urban Center. • On May 25, 2012, County Staff presented to the Board an 18-month approach to developing Transportation Design Standards for the remaining urban activity centers and revitalization areas in Fairfax County. Department of Transportation 4
  5. 5. County of Fairfax, Virginia Background – Continued • In March, 2013, the DRPT released the Final Draft of the State’s Multimodal System Design Guidelines. • The County, VDOT and DRPT have continually been working to complete the development of the Urban Transportation Design Standards for Fairfax County. Department of Transportation 5
  6. 6. County of Fairfax, Virginia The Current Process • VDOT is creating an appendix to it’s Road Design Manual that will establish state-wide urban design criteria for urban and mixed-use activity centers, and revitalization areas. • Fairfax County is developing a GIS based multi-modal system map, that encompasses functional classifications, multi-modal systems, urban transect zone designations (T1-T6), and urban center classifications (P1-P6). • Fairfax County will develop, based on modal emphasis/priority, the recommended urban roadway criteria and cross section for each major through corridor, and each urban activity center (place-making) corridor within the County’s urban and mixed-use districts.

Curb-Return Radii • Curb Extensions “Bulb-Outs” • Landscaping Provisions • Operating Speed • Utility Placement • Design Control Vehicles • Maintenance Responsibilities County staff are in continued negotiation with VDOT to further develop and refine the Draft VDOT RDM urban streets standards, so that the County’s comprehensive plan can be implemented with the fewest number of design exceptions and waivers.

  15. 15. County of Fairfax, Virginia Expected Timeframe and Remaining Tasks • Fairfax County and VDOT expect to complete the adoption of the County’s Transportation Design Standards within the next six months. There are several remaining tasks: – VDOT needs to complete and have adopted the Urban Design Standards Appendix to the State’s Road Design Manual. – Fairfax County needs to complete the compilation of it’s multi-modal system plan, and bring the recommended plan and street sections to the Board for approval. – The County needs submit its recommended multi-modal system plan and street sections to DPRT review, and to VDOT for acceptance. – An MOA may be required in order to resolve maintenance responsibilities within the County’s Urban Activity Centers.
