Project Development Workflow Tasks (PDWT)

Part 3 - Identify Project Need and Project Initiation Document

II. Project Initiation Document

A. Define Transportation Need and Assess Site (150.05) - Identify Environmental Constraints (150.05.20)

P28. Identify Environmental Constraints

The project engineer must become aware of environmental constraints that are known to exist within or adjacent to the project limits. This is best accomplished by consulting with the PDT’s Environmental unit representative who can perform an initial review of current environmental issues documented or known for a particular site. Early awareness of environmental constraints will enable avoidance during the engineer’s development of project alternatives. The project’s schedule, cost and environmental document type are directly related to environmental impacts, thus development of environmentally friendly alternatives ensures impacts and mitigation are minimized. Projects within the coastal zone present difficult issues that may have significant impact to project schedules and scope of work. Careful consideration of environmental constraints will help to reduce the risk of re-working the development of project alternatives. Early involvement with the Environmental representative cannot be stressed enough.

As the project progresses during the PID development, the project engineer will request a Preliminary Environmental Evaluation Report (PEAR as discussed under the Request Preliminary Environmental Evaluation task under the Develop Concept Alternatives activity.
