Metrorail expaion to Dulles Airport Policy of higher deity, mixed use development in activity centers Tyso is not sustainable as exists today 17,000 residents to 105,000 jobs 167,000 parking spaces 5
The Vision A livable urban center with: Trait-oriented development A variety of modes for trip making Fewer parking spaces Pedestrian and bicycle friendly streets A defined see of place throughout Tyso Residents to Jobs mix of 100,000/200,000 6

Memorandum of Agreement (MOA) and Traportation Design Standards for Tyso Set up to implement the design standards and address permitting and maintenance issues Developed by Fairfax County and VDOT with input from numerous stakeholders Purpose Develop a platform by which the Tyso Compreheive Plan could be implemented Facilitate the provision of traportation facilities that accommodate low speed roadways, pedestrian and bicycle facilities and trait services 11
Tyso Memorandum of Agreement VDOT Review and approve pla using Tyso Standards Accept new streets that conform to VDOT and Tyso Standards including phased and stubbed streets Issue permits for work to be performed on the streets Maintain existing and future streets that have been accepted into the primary and secondary system Respoibilities Fairfax County Eure that the development is in conformance with the Tyso Standards Eure that access rights are provided on any new street cotructed as a phased or stubbed street to allow for maintenance and public safety vehicles to turn around safely 12
Tyso MOA Non-Standard Features The placement of non-standard features within the ROW are subject to VDOT review for safety and operational issues Such facilities when approved shall be subject to the following: Non-standard feature should be allowed only through the issuance of a permit by VDOT Permittee may be Fairfax County or private developer VDOT is not obligated to cotruct, itall, operate, maintain or replace any such feature Features will be operated and maintained by the holder of the VDOT permit 13
Facilities Not Included in the Standards Employed by VDOT (Non-Standard Features in Attachment A of MOA) 1. Decorative and ornamental lighting features 2. Decorative and ornamental traffic signals 3. Special landscaping materials, planting beds, raised planters, street trees, root cell structures, tree cages and other landscaping materials 4. Special and decorative roadway or sidewalk paving 5. Special drainage features, underground storage and mechanical vault structures, and innovative drainage features such as rain garde (conceptual graphic examples shown in Attachment B of the MOA) 6. Special signage such as way finding sig 7. Street furniture such as benches, trash receptacles, kiosks 8. Bus shelters and other trait related facilities 9. Parking meters 10. Decorative, non-standard retaining walls 14
Memorandum of Agreement on Urban Standards for Tyso 1. Functional Classification and Right-of-Way Limits 2. Level of Service Standards 3. Design and Operating Speeds 4. Access Management 5. Lane Widths and On-Street Parking 6. Median Islands and Center Turn Lanes 7. Turn Lane Lengths 8. Horizontal Radius 9. Length of Vertical Curve 10. Design and Control Vehicles 11. Driveway Widths 12. Intersection Sight Distance 13. Multi-Modal Design Characteristics 14. Pedestrian Facilities 15. Bicycle Facilities 16. Utility Placement 15
Level of Service Standards (1) The minimum designated standard for NHS designated streets is D, while the standard in the Tyso Compreheive Plan is E. The VDOT District Administrator may accept a lower standard for NHS routes upon review of an Operational Analysis. Where LOS D/E cannot be achieved, mitigation measures must be coidered. A LOS Waiver is required and is administered by the VDOT District Administrator. (2) Where LOS E standard cannot be achieved, mitigation measures must be coidered. LOS Waiver is not required. 16
Level of Service (LOS) Standards The vehicular LOS needs to be balanced with a high LOS for walkability, cycling and trait The LOS needs to be balanced with economic development objectives To provide the balance, it is necessary to apply the tiered approach where the location does not meet the LOS standard 17
LOS Tiered Approach 1. Analyze the location not meeting the LOS standard providing aggressive TDM or multi-modal mitigation measures 2. Evaluate whether additional grid links can be cotructed 3. Coider temporary traffic mitigation measures 4. Determine whether an acceptable balance has been achieved between vehicular LOS and pedestrian, cycle and trait mobility 5. If acceptable balance has not been achieved, make land use adjustments 6. If acceptable balance has not been achieved, coider turn lanes to improve LOS without seriously compromising pedestrian, trait and bicycle mobility 18
Design and Operating Speed Tyso uses a modified functional classification Design speed is primary control for: Minimum intersection sight distance Minimum sight distances on horizontal and vertical curves 19
Access Management Existing intersectio are exempt Intersection spacing represents min and max to help implement the street grid It is very important to plan for Access Management early in the development process 20
Design and Control Vehicles for Designing Street Intersectio Design Vehicle is one that must be accommodated without encroachment into the opposing traffic lane The Control Vehicle is: Infrequent Must be accommodated: By allowing encroachment into opposing lanes or Minor encroachment into the streetside area or As a last option multiple-point tur of vehicle 21
Pedestrian Facilities 1. Building zone 2. Sidewalk 3. Landscape amenity panel 22
Coolidated Traportation Impact Analysis 23
CTIA Process Stakeholder outreach and participation Coeus on grid to be studied VISUM Tiered approach Minimizing ROW needs Balancing pedestria and vehicles Focus on intersectio with highest delay Rounds of mitigation Coeus of improvements needed Documentation and VDOT review 24
Use of CTIA Baseline for reviewing traportation improvements and proposed grid of streets Set expectatio for development community Traffic information that can be used to refine larger infrastructure projects. 25
Lesso Learned MOA and Design Standards has helped the review and approval process CTIA helped development of baseline There is always a need to provide additional clarificatio Addition of stakeholders complicates the process but is critical to buy in VDOT and Fairfax County don t always interpret the standard the same way but coordination makes it work 26
Questio? 27
Trait Infrastructure Circulator The Tyso Circulator Study identifies the internal routes to serve Tyso Portio of these routes will be on exclusive circulator lanes Identification of circulator statio critical for coordination with development 28
Trait Infrastructure - Metro The Metrorail Silver Line includes four statio in Tyso Some pedestrian and bike facilities to enhance connectio to Metro statio may not be provided until redevelopment 29
Tyso Planning Background Task Force & Community Workshops (2005-2008) Planning Commission Committee & Staff (2009-2010) Compreheive Plan, adopted June 22, 2010 Zoning Ordinance, adopted June 22, 2010 Planned Tyso Corner Urban District (PTC) 30
Purpose of Re-Planning Tyso Link land use planning to investments in traportation (Metro, circulator, ped and bike facilities) Regional growth management strategy to concentrate development in activity centers Reduce vehicle trips by providing multimodal optio 31
The Vision for Tyso 100,000 Residents/200,000 Jobs More housing Grid of streets Multimodal emphasis Reduced parking supply 32
Tyso Urban Design Street grid and urban block size (min & max) Urban streetscape Building heights up to 400 feet near Metro, lower in surrounding neighborhoods Build to Line (maximum setback rather than min setback requirement) 33
Tyso Traportation Infrastructure Requirements Implementation Issues 34
Grid of Streets 35
Grid of Streets Functional classification guides the application of design standards in Tyso Provide flexibility in Master Plan to Change the Grid 36
Parking On-Street parking required for Avenues, Collectors and Local Streets No minimum off-street parking for most uses adjacent to Metro Off-street parking maximum within the Tyso Area Make provisio to accommodate existing leases at redevelopment sites 37
Parking (continued) Additional parking on a site not required with a change in land use Temporary parking facilities allowed near Metro statio Site plan approval for temporary parking facilities requires queue analysis for the gates 38
Bicycle Facilities Bullet on bicycle master plan Bullet on how to handle short section of bike lanes Bullet on using funds to connect facilities not provided by development 39
