Section 2-01 Design and Environmental Flowcharts

INTRODUCTIONGeneral. The attached flowcharts outline the design and environmental processesfor major road construction projects such as reconstruction, widen & overlay, etc.They are not intended for projects such as overlay projects which do not require aninvolved interaction between design disciplines or a building block approach todesign development. A detailed discussion of the flowcharts and their relatedprocesses is provided in subsequent sections of Chapter 2.

NEPA Analysis and Documentation Flowchart: The National EnvironmentalPolicy Act (NEPA) is an established procedure to ensure all project stakeholdershave a voice in shaping projects on the national highway system and other projectsconstructed with federal funds. The NEPA Analysis and Documentation Flowchartprovides a graphical representation of the NEPA procedures to be applied.

Design Process Flowchart: Defines the design development process with nodes thatdelineate the linear progression of key plan issuances and activities. Shown aboveeach node is the data required to complete the node task, and below each node is alist of the tasks required by each program or section to continue the design process.See Section 2-02 Design Process for specific details as to how a project designrelates to the flowchart.

Environmental Process Flowchart: Overlays the NEPA process, with the majornodes of the WYDOT Design Process Flowchart to provide insight as to how thevarious processes interact with the overall project design. See Section 2-03Environmental Process for specific details of the NEPA documentation to addressthe project impact and need.
