DESCRIPTION: This report is created by consultant biologists at the request of the project engineer when a highway project may have an environmental impact. The Federal Highway Administration requires these records if federal money is to be used. The consultant biologists study the location of proposed projects, look for endangered species of plants or animals, and determine how a highway would threaten them. The report includes an abstract of assessment (location and species affected), detailed description of where species can be found, observations, and recommendations. This report may have a summary if part of a larger study, depending on the size, type, and location of the proposed highway. Several of these reports may be completed over the course of highway construction. They document the changing environment and are subject to litigation.
