7. Context Sensitive Solutions in Transportation
CSS - 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 Transportation
CSS - 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 Transportation
CSS - 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 Transportation
CSS - 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 Transportation
CSS - 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 Transportation
CSS - 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 Transportation
CSS - 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 Transportation
CSS - 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

15. Context Sensitive Solutions in Transportation
CSS - 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 people's 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

Stakeholders 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

19. Context Sensitive Solutions in Transportation
CSS - 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 Transportation
CSS - 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

Case Study Planning, Environmental Analysis and Design
Woodville, Texas Project Location
TxDOT Beaumont District
Goal of the study:
Develop design alternatives for a
major transportation corridor
through the rural community of
Woodville, Texas.
Specific Objective:
Avoid possible environmental
impacts and improve community
impacts due to construction of the
proposed U.S. Highway 69.
22. Context Sensitive Solutions in Transportation
Site Conditions Planning, Environmental Analysis and Design
Rolling terrain covered with pines and
oaks, and rich bottomlands with tall
hardwoods and some wetland areas.
City is surrounded by units of the Big
Thicket National Preserve, the
Angelina National Forest is to the
north, and to the east is the Sam
Houston National Forest.
Turkey Creek, a 30-mile long
watercourse flows through Tyler and
Hardin Counties. This creek has
been proposed as a connecting
corridor in the "String of Pearls"
concept for Big Thicket National Park.
