Where do we want to end up?
• Understand the concepts of CSD
• Apply CSD to a real project process
• See where the theory of CSD has been successful
3
Background
• 1991 ISTEABalanced transportation projects with community and environmental values.
• 1997 FHWA/AASHTO, Flexibility in Highway Design
Identifies flexible highway design tools available to help sustain important community interests without compromising safety.
• 1998 FHWA/AASHTO/Maryland DOT,
“Thinking Beyond the Pavement” National Workshop
Encouraged the best ways of integrating highways with their communities and the environment while maintaining safety and mobility.

Context Sensitive Design
…is a collaborative approach, which involves all stakeholders to develop a transportation facility that fits its physical setting and preserves scenic, aesthetic, historic, and environmental resources, while maintaining safety and mobility.
5
Principles
Qualities• Project satisfies purpose and need
• Safe facility for user and community
• In harmony with the community while preserving environmental values
• Efficient and effective use of resources
• Minimal disruption to the community
• Adds lasting value to the community
• Achieves excellence in people’s minds
6
Principles
Characteristics• Establish multi-disciplinary team early
• Understand the community and valued resources before designing
• Involve a full range of stakeholders, purpose clear
• Process examines multiple alternatives
• Commitment to the process from top officials and leaders
• Open, continuous communication with stakeholders
• Public involvement process is tailored to the project
7
Why is CSD Important?
• Promotes active citizen participation• Balances community needs with transportation
goals• Provides an integrated development framework• Seeks stakeholder and community values• Puts the customer first• Enhances community acceptance• Encourages a lasting public works legacy
8
Benefits
• Making development decisions for the right reasons
• Better protection for the environment and other community assets
• Projects look and fit better into their physical setting
• Enhances community livability and sustainability
• Can save time and money by reducing “rework” cycle
• Creates opportunities for design excellence

What is Context?
Context is everything related to the environment, places, and people where a project is located.
10
Every Project has Context!

Understanding Context
• Natural Resources
• Community Resources
• Cultural Resources
• People

Advisory Committee-Provide Input
-Provide Business Perspective-Identify Deficiencies
-Suggest Mitigation Strategies-Provide two-way communication between
Advisory Committee and organization
Context Sensitive Design Workshop-Identify Community Values and Issues-Identify Opportunities and Constraints
-Consider Roadway Safety-Develop Corridor Vision
Residents-Identify Issues
-Review and Comment on Mitigation Strategies
Design Consultant-Provide Technical Support
& Analysis
22
Why are we going through the process?
• Create a suitable corridor
• Identify community values & issues
• Guarantee the opportunity to participate
• Share stakeholder viewpoints, visions, and goals
• Understand the transportation constraints
23
What won’t this workshop do?
• Determine corridor alignment
• Guarantee everything will happen
• Accuse or be confrontational
• Win or Lose
• Compromise safety
24
Goal
To BALANCE:
•Community values
•Environmental considerations
•Safety and capacity
•Economic realities

Stakeholder Input
An opportunity to bring YOU, the community stakeholders, into the project study process early:
– to provide input as individuals and community representatives
– to identify community issues
– to share values
– to determine important elements related to the project
– to consider what the BALANCE between safety, capacity, community, and environment is fair and practical
35
Traffic & Transportation Issues
• Truck vs. car traffic
• Destination vs. thru traffic
• Pedestrian Circulation: safe crossings, bikeways
36
Business & Commerce Values
• Maintain small town image vs. the strip
• Maintaining good commerce flow-goods, services, people
• Maintaining appropriate land use – residential, business, industry
37
Environmental Values
• Visual & scenic preservation
• Cultural – architecture, archeological, historical features
• Natural resources – wetlands, lake, bluffs
38
Tourism & Recreation Values
• Should this be a destination community corridor?
• What is the emphasis on local & regional tourism?
• What is the importance & value of recreation in the corridor?
39
The BIG question is…
What is the
BALANCE
between community/corridor and transportation needs?
40
• Analyze and Evaluate Input from CSD Workshop
• Develop Alternatives to Balance:– Safety– Mobility– Environment– Economic Investment
• Present Alternatives to Advisory Committee for Review and Comment
• Revise Alternatives
• Public Information Open House – Present Feasible Alternatives for Review and Comment
