You have discovered the optimal sites for building the new school. All the locations in the Filtered optimal areas layer are suitable. The last step in this exercise is to locate the best site out of the alternatives. The roads layer displays the roads within the town of Stowe. By examining the Filtered optimal areas layer with the roads layer, you'll see that there are some suitable areas for the school site that are not close to roads within the town. You'll first exclude these areas by locating suitable sites that are intersected by roads. Then you'll locate the best site based on area. An optimal school site is larger than 10 acres, or 40,469 square meters.
