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

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

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

28

34

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
