A proposal within the unincorporated jurisdiction of the County of Pueblo which falls within one or more of the following criteria shall be considered site selection of arterial highways, interchanges, and collector highways requiring application to this Board for a permit to conduct such activity:

   A. The proposal represents a limited-access highway which is part of the federal-aid interstate system, or a limited-access highway constructed under the supervision of the Colorado State Department of Highways.

   B. The proposal will eventually serve corridor movements having trip length and travel density characteristic of substantial Statewide or interstate travel.

   C. The proposal will result in the service of all, or nearly all, urban areas having a population of fifty thousand (50,000) or more, as well as the greatest majority of population centers having a population of twenty-five thousand (25,000) and more.

   D. The proposal will serve the major activity centers of a metropolitan area, the highest traffic volume corridors, the longest trip itineraries, and carry a high proportion of the total urban travel of minimum mileage, the major portion of trips entering and leaving the urban area, as well as the majority of through-traffic movements by-passing the urban center, or serve significant intra-area travel, such as between central business districts and outlying residential areas, between major intra-city communities, or between major suburban centers.

   E. The proposal represents a major thoroughfare serving as a corridor or link between municipalities, unincorporated population centers, and constructed under guidelines and standards established by, or under the supervision of, the Colorado State Department of Highways.

   F. The proposal involves the intersection, or transfer of traffic, between two or more of the types of highways described in Subsections B through E of this Section, at grade or with grade separation.

   For the purpose of this Chapter, "site selection" shall mean the preliminary selection of a highway corridor which is not in the 1990 Thoroughfare Plan for Pueblo, and application for a permit to engage in such activity shall be required before any earth moving or other work is done which shall physically affect the site selected. Once a permit has been issued for site selection of a highway corridor, however, this Board shall not thereafter be concerned with the further refinement of design, engineering or construction related to such activity. The person or entity engaging in or planning the activity shall, however, apply to this Board for an additional permit in the event that changes in plans should result in the moving or expansion of the activity to a site not approved in the original permit. Any permit granted by this Board shall simply state that the particular activity for the particular site or corridor therein described shall be allowed.
