What is CSS?
More than Mitigation . . .
More than Enhancements . . .
More than a Fad . . .

• Strive towards a shared stakeholder vision to provide a basis for decisions
• Demonstrate a comprehensive understanding of contexts
CSS - Principles
Context Sensitive Solutions in Transportation Planning, Environmental

8
• 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
CSS - Principles

CSS - Characteristics
• 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

Analysis and Design
10
CSS - Characteristics
• 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

11
CSS - Characteristics
• 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
Context Sensitive Solutions in Transportation Planning, Environmental
Analysis and Design
12
CSS - Characteristics• 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

CSS is not about . . .• Compromising safety and standards• Responding only to the “squeaky wheel”• Spending more time and money• Tacking on enhancements
CSS - Myths

14
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
CSS - Outcomes
Context Sensitive Solutions in Transportation Planning, Environmental
Analysis and Design
15
• 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

19
• 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
CSS - Benefits
Context Sensitive Solutions in Transportation Planning, Environmental
Analysis and Design
20
• 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

Analysis and Design
Project LocationWoodville, TexasTxDOT Beaumont DistrictGoal 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.
Case Study
Context Sensitive Solutions in Transportation 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.

* Notes:1.) Calculated costs are meant for comparison purposes only and do not represent actual construction costs of the roadway.2.) Same extents were used to calculate the costs of each alternative.3.) Frontage road embankments, underpasses and culverts were not included in estimates.4.) For cost estimate, median between main lanes was considered paved.5.) See appendix, page 19, for detailed cost descriptions
