This dataset contains the GIS analysis areas for each individual feature of planned transportation project alternatives in the Efficient Transportation Decision Making (ETDM) Process. Alternatives are made up of one or more features of different geometry types (e.g. point, line, polygon). The polygons in this layer, which are referred to as "feature areas", are created by buffering the individual features at a distance of a half mile. The resulting buffer is a representation of each unique feature within a project alternative where prescribed GIS analyses take place. The project alternatives associated with these feature areas currently have a status of ETAT Review. |
