 The corridor analysis funnel is a high-level depiction of the siting process. The inputs to the funnel include community considerations, natural environment considerations, and engineering considerations. Now the community considerations include things like human and cultural resources, the natural environment includes things like plants, animals, and water resources, and the engineering considerations include physical constraints on the systems and features that would maximize location and minimize cost and schedule delays. The information derived from each of these considerations is put into a geographic information system to determine values and weights for each of the considerations. Now as we move down through the funnel, the area of interest becomes more focused and defined and the data become more detailed and accurate. Exiting the funnel is a culmination of the siting methodology where a preferred route or center line is proposed for the transmission line. Now as you go through the GIS analysis part of the project, you will analyze these considerations simultaneously to objectively determine the most suitable line location. To do this manually would require many man hours of work, would be less accurate in the final outcome, and could lead to increased litigation, project delays, and cost escalation because of a lack of objectivity and transparency.
