  • 1. Context Sensitive Solutions in TransportationClass 3 Planning, Environmental Analysis and Design 1
  • 2. Context Sensitive Solutions in TransportationClass Exercise Planning, Environmental Analysis and Design So…What does Context Sensitive Solutions mean to you? 2
  • 3. Context Sensitive Solutions in TransportationClass Exercise Planning, Environmental Analysis and Design Context? 3
  • 4. Context Sensitive Solutions in TransportationClass Exercise Planning, Environmental Analysis and Design Sensitive? 4
  • 5. Context Sensitive Solutions in TransportationClass Exercise Planning, Environmental Analysis and Design Solutions? 5
  • 6. Context Sensitive Solutions in TransportationWhat is CSS? Planning, Environmental Analysis and Design More than Mitigation . . . More than Enhancements . . . More than a Fad . . . Michigan DOT 6
  • 7. Context Sensitive Solutions in TransportationCSS - Principles Planning, Environmental Analysis and Design • Strive towards a shared stakeholder vision to provide a basis for decisions • Demonstrate a comprehensive understanding of contexts 7
  • 8. Context Sensitive Solutions in TransportationCSS - Principles Planning, Environmental Analysis and Design • Foster continuing communication and collaboration to achieve consensus • Exercise flexibility and creativity to shape effective transportation solutions, while preserving and enhancing community and natural environments 8
  • 9. Context Sensitive Solutions in TransportationCSS - Characteristics Planning, Environmental Analysis and Design • Establishes/Involves an interdisciplinary team early – full range of stakeholders in all phases of a transportation program (including transportation officials) – skills based on the needs of the transportation activity • Seeks to understand – the landscape – the community – valued resources – role of all appropriate modes of transportation in each unique context before developing engineering solutions 9
  • 10. Context Sensitive Solutions in TransportationCSS - Characteristics Planning, Environmental Analysis and Design • Communicates early and continuously with all stakeholders – open, honest, and respectful manner – tailors public involvement to the context and phase • Utilizes a clearly defined decision-making process • Tracks and honors commitments through the life cycle of projects 10
  • 11. Context Sensitive Solutions in TransportationCSS - Characteristics Planning, Environmental Analysis and Design • Clearly defines the purpose and seeks consensus – shared stakeholder vision – scope of projects and activities – incorporates transportation, community, and environmental elements • Secures process commitments from local leaders • Tailors the transportation development process – to fit the circumstances – process that examines multiple alternatives, including all appropriate modes of transportation – results in consensus 11
  • 12. Context Sensitive Solutions in TransportationCSS - Characteristics Planning, Environmental Analysis and Design • Encourages agency and stakeholder participants to jointly monitor how well the agreed-upon process is working – to improve as needed – to identify any lessons learned • Encourages mutually supportive and coordinated multimodal transportation and land-use decisions • Draws upon a full range of communication and visualization tools – to better inform stakeholders – encourage dialogue – increase credibility of the process 12
  • 13. Context Sensitive Solutions in TransportationCSS - Myths Planning, Environmental Analysis and Design CSS is not about . . . • Compromising safety and standards • Responding only to the “squeaky wheel” • Spending more time and money • Tacking on enhancements 13
  • 14. Context Sensitive Solutions in TransportationCSS - Outcomes Planning, Environmental Analysis and Design Qualities of Excellence in Transportation Design • Satisfies the purpose and needs of stakeholders forged early in the project and amended throughout project development • Safe facility for the user and the community • In harmony with the community, preserves environmental, scenic, aesthetic, historic, and natural resource values of the area, i.e., exhibits context sensitive design 14
  • 15. Context Sensitive Solutions in TransportationCSS - Outcomes Planning, Environmental Analysis and Design Qualities of Excellence in Transportation Design • Exceeds expectations of designers and stakeholders and achieves a level of excellence in peoples minds • Involves efficient and effective use of the resources (time, budget, community) of all involved parties • Designed and built with minimal disruption to the community • Seen as having added lasting value to the community 15
  • 16. Context Sensitive Solutions in TransportationWhy Use CSS? Planning, Environmental Analysis and Design Decide Design Defend Re-Design Delay Listen Design Build Michigan DOT 16
  • 17. Context Sensitive Solutions in TransportationStakeholders Planning, Environmental Analysis and Design Potential CSS Stakeholders • Neighborhood associations and civic organizations (communities) • Land developers and builders • Metropolitan planning organizations (MPOs) • City and county regional planners • State DOT transportation planners & engineers • Federal and state resource agencies • Regional transit authorities 17
  • 18. Context Sensitive Solutions in TransportationSpecial Interests? Planning, Environmental Analysis and Design 18
  • 19. Context Sensitive Solutions in TransportationCSS - Benefits Planning, Environmental Analysis and Design • Solves the right problem – reaches consensus with all stakeholders before the design process begins. • Conserves environmental and community resources • Facilitates and streamlines NEPA process compliance • Saves time – gains consensus early – minimizes litigation and redesign – expedites permit approvals • Saves money – shortens project development process – eliminates/minimizes obstacles 19
  • 20. Context Sensitive Solutions in TransportationCSS - Benefits Planning, Environmental Analysis and Design • Builds support from the public and from the regulators – partnering with the transportation agency – parties bring full cooperation – often additional resources • Helps prioritize and allocate scarce transportation funds in a cost-effective way • Group decisions are generally better than individual decisions – more accepted and mutually satisfactory when made by all who must live with them • Serves the public interest, helps build communities and leaves a better place behind 20

Context Sensitive Solutions in TransportationSite Conditions Planning, Environmental Analysis and DesignRolling terrain covered with pines andoaks, and rich bottomlands with tallhardwoods and some wetland areas.City is surrounded by units of the BigThicket National Preserve, theAngelina National Forest is to thenorth, and to the east is the SamHouston National Forest.Turkey Creek, a 30-mile longwatercourse flows through Tyler andHardin Counties. This creek hasbeen proposed as a connectingcorridor in the "String of Pearls"concept for Big Thicket National Park.
