Category:126 Location Study and Alternatives Analysis

Introduction

A location study (LS) is required for all projects with an environmental impact statement (EIS), an environmental assessment (EA) or of a complexity that precludes the use of a conceptual study. A location study is prepared to determine the most advantageous location and type for a proposed highway improvement based on project purpose and need and on engineering and environmental constraints. The location study and the environmental analysis are developed in conjunction with each other. They are not stand-alone documents.

A location study is not a programming activity; rather it is a method to determine the most advantageous way of fulfilling the program intent. This does not preclude the necessity for sometimes studying additional portions of the routes beyond the limits of the section programmed or recommending a type of improvement not originally the intent of the program. Any deviation from or extension to program intent is set out clearly in the study.
