Whenever practical, would-be Sponsoring Government(s) are strongly encouraged to join together with other city, port and county cosponsors through mutual re-/designations and boundary changes, in order to:
In the case of a rural zone in sparsely populated counties:
By 15 miles or less; or
By more than 15 miles for any city with a population of 2,000 or less, based on the most recently available estimate from the Portland State University Population Research Center, whenever the waiver described in OAR 123-650-1100 (Extended Rural Distances)(4) is feasible and appropriate.
The obligation in section (2) of this rule extends equivalently to ports or counties that are cosponsors or would-be Sponsoring Governments, including but not limited to areas outside of UGBs being brought into an enterprise zone that is (also) sponsored by one or more cities.
Exist at any one time inside the UGB of any city, whether or not it sponsors the zone, except that two zones are allowed inside the UGB of a city with a population of 100,000 or more, based on the most recently available estimate from the Portland State University Population Research Center.(b) Be designated per county for a zone containing solely unincorporated territory, as sponsored by the county or a port in that county but not by any city. The Department may still allow an exception to this subsection if finding that the second or third such zone in the county:(A) Is located in a rather distant and different part of that county;(B) Comprises near areas in another county; or(C) Would serve one or more exigent business development opportunities, and that distances within the county or other factors render other options impractical or counterproductive.
