    involved with more input into decision-making
  • Expectation to find context sensitive solutions
  • Requirement to maintain safe, economical,
    sustainable, and technically sound facilities
  • Fiscal and budget constraints, rising
    construction costs and budgetary impacts

9
Opportunities
  • Advancements in digital technology
  • Integration of data and knowledge from diverse
    sources and multiple media
  • Collaboration, data sharing, decentralization
  • Communication media, speed, and coverage
  • Leveraging advances in related industries
  • Capability to better visualize, evaluate and test
    design scenarios during development
  • Interdisciplinary, team culture and flexibility

10
CSS Approach
  • Outcome satisfies the purpose and need
  • Explores alternatives that equally address goals
    for safety, mobility, protection of the
    environment, and reflect community values
  • Involves a collaborative, interdisciplinary
    approach, and effective use of resources
  • Involves stakeholders, resource agencies and the
    public as a part of the design team
  • Ensures that outcome provides safety and
    mobility, and adds lasting value

11
Why Does FLH Emphasize Context Sensitive
Solutions?
  • Enables the organization to achieve its vision
  • FHWA Vision Improving Transportation for a
    Strong America
  • FLH Vision Create the best transportation system

the values of Federal and Tribal lands
  • in balance
    with

12
Perspective and Philosophy
  • Long-standing partnerships with FLMAs
  • Sensitivity to FLMA goals and values
  • Joint Responsibility to Deliver Program
  • Use expertise gained from partner agencies
  • Share complementary knowledge skills
  • National Perspective
  • Partner with many agencies and State DOTs
  • Broad geographical coverage
  • Able to accommodate partner agency standards
  • Retain Federal stewardship responsibility

13
Typical CSS Applications
  • Project Planning and Programming
  • Project Development
  • Environment
  • Technical Services
  • Project Management
  • Construction

14
FLH Application of CSS
  • Interdisciplinary Team Approach
  • Collaborative Decision-making involving all
    Stakeholders and the Public
  • Balance Safety and Mobility Goals with Community
    Values Environment
  • Flexible Application of Design Standards
  • Primarily used in Design and Construction
    limited use in Planning and Programming

15
What FLH Emphasizes
  • Establish interagency, multi-disciplinary team
    based on project needs, purpose and scope
  • Use early public involvement, integrated with
    scoping, to establish the purpose and need
  • Facilitate continuous communication and feedback
    with partners and stakeholders
  • First, understanding the project context to guide
    the evaluation of alternatives which address the
    mobility and safety needs
  • Collaborative, participative decision-making

16
Levels of Decision-making
  • Expert-based
  • Stakeholder-based
  • Community-based

What Level Is Requested?
17
Recommended Practices
  • Verify the sound, factual basis for the purpose
    and need
  • First listen to those who may be affected, before
    proposing a design solution(s)
  • Be flexible to consider alternative,
    corridor-specific design criteria that meets the
    need
  • Understand the basis for design criteria, and how
    it affects and addresses operational performance
    and safety risk

18
Recommended Practices
  • Verify what is needed for collaborative
    evaluation and decision-making
  • Be ready, willing, creative and innovative to
    respond to local and environmental concerns
  • Progressively fine tune the details that result
    in a better fit to the site conditions
  • Follow proven processes that attend to details
    affecting quality, for all disciplines

19
Improve the Design Process
  • Ideas, analysis and criteria interact to create
    the solution.
  • Advancing the vertices improves the process.
  • Enhancing the vertices improves the solution.

20
Data and Performance
  • Better data and tools needed for effective
    engagement of stakeholders and public
  • Understanding the basis for design will result in
    a higher level of performance
  • Facilities in sensitive environments face higher
    demands for performance
  • Analysis, engineering, and construction all
    should be accomplished with higher levels of
    thinking, performance and quality

21
Using Visualization to Support the CSS Approach
  • Communicating the design process

22
Why use Visualization?
  • Promotes Context Sensitive Solutions
  • Facilitates Involvement with Stakeholders and the
    Public
  • Promotes Common Understanding
  • Simulates the Proposed Facility
  • How it Looks (End Product)
  • How it Operates (Meets Needs)

    programs - mandates conformance to AASHTO and/or
    other FHWA-approved State DOT policies
  • FLH Program Manual and Interagency Agreements
    (MOUs) sets FLH policy
  • FLH PDDM references FLH policy and establishes
    FLH standard practices, guidance, and expected
    design flexibility

25
Highway StandardsUsed by FLH
