Optimal Corridor Analysis (Total Accumulated Surface) (62,38) = 100.63 (Transmission line) Start Total Accumulation Surface —sum of Start and End surfaces …the example location is 100.63 units along it optimal path back to the Start. Similarly, it is 95.89 units to the End. This means the location lies on an optimal path that is a total of 196.52 units long which is the lowest total value therefore on the Optimal Path (valley bottom) (62,38) = 95.89 End (substation) (62,38) = 100.63 + 95.89 = 196.52 Total Accumulation Surface (Berry)

Optimal Corridor Analysis (195-400 Filled) …all best paths “forced” through all project locations– no siting discrimination Flooding the Surface —includes increasing less optimal routes (Nth Best Paths) (Berry)

Optimal Corridor Analysis (195-205 Filled) …a very workable set of Nth Optimal Paths as the “pinch points” (narrow gaps) and the broad plains of similar opportunity are well defined …205-195= 10 / 195= .05= top 5% of all best path rankings Flooding the Surface —includes increasing less optimal routes (Nth Best Paths) (Berry)

Optimal Corridor Analysis (195-200 Filled) …beginning to loose some suitable paths for consideration (top 2.5%) Flooding the Surface —includes increasing less optimal routes (Nth Best Paths) (Berry)

Optimal Corridor Analysis (195-196 Filled) …too little “decision space” as the Optimal Corridor is effectively the Optimal Path and assumes that the criteria, calibration and weighting of the model are all inclusive and perfect Flooding the Surface —includes increasing less optimal routes (Nth Best Paths) (Berry)
