The general purpose of this report is to examine various constraints, resulting from human settlement patterns, which will affect the selection of a route for the proposed pipeline corridor. In addition to the definition of constraints, the report will also identify factors which, unlike constraints which are primarily negative in nature, would attract or encourage a proposed corridor route. The report will ultimately become an appendix to the first volume of the Corridor Study which will contain the recommended route for the pipeline corridor. The report contains, therefore, not only information and opinions relating to human settlement patterns, but recommendations regarding locational factors which the Study Group should consider in selecting the recommended corridor routes or alternative routes.
