"Enterprise Zones" were recently discussed by the BOS, with only one day's -- not even a weekend's worth -- notice to the public.  Here's some basic info on Enterprise Zones:
    "Enterprise zones" are discussed in ARS 41-1521 through -1528.
    An "enterprise zone" is a geographic area organized to encourage "Incentives and initiatives that local governments in the proposed zone will provide or establish to encourage businesses to locate in the proposed zone.  These may include economic or financial incentives or priorities, increased public services, improved infrastructure, structural rehabilitation and regulatory simplification and expedition."  ARS 41-1524.A.5.
    An "enterprise zone" may be created in areas of high unemployment or high poverty.  A zone may be created if, in or around it, either average annual unemployment for the last two years was at least 150% of the statewide rate, or poverty is at least 150% of the statewide rate.  ARS 41-1523.A.
    An enterprise zone must be entirely within one county, must be one connected area, and can't surround an area that's not included.  A zone must be at least 1/4 square mile, and have at least 1000 residents.  And a zone "shall be based on historic community or neighborhood identity."  ARS 41-1523.B.
    If an enterprise zone is formed, an Enterprise Zone Commission must also be formed.  ARS 41-1522.
    If an enterprise zone is entirely within a city, or the unincorporated part of a county, then the governing body of the city, or the county, shall serve as the Enterprise Zone Commission.
    But if an enterprise zone includes areas both inside and outside an incorporated city, then the city and county "shall jointly establish a commission by intergovernmental agreement" under ARS 11-951 through -954.  Whatever such a commission agrees to do, "No agreement made pursuant to this article shall relieve any public agency of any obligation or responsibility imposed upon it by law," ARS 11-952.C, and "Except for the right of joint exercise of powers granted in this article ... nothing contained in this article shall be so construed as to authorize any public agency to exercise any power or engage in any business or enterprise that such public agency is not authorized to ... engage in pursuant to other provisions of law," ARS 11-954.
    An intergovernmental commission may include either the county BOS alone, or representatives from the BOS and the governing body of the city based on the relative population of the county and city areas within the proposed zone.  ARS 41-1522.B.  But if any part of a city is included in the zone, a representative of the city shall at least be a nonvoting advisory member.  ARS 41-1528.
    The application to form an enterprise zone is made to the state department of commerce, which may, after a public hearing, certify the area as an enterprise zone.  However, the department shall set a termination date no more than five years after the zone is designated (though a zone may be renewed).
    Recall that the purpose of an enterprise zone is to encourage "Incentives and initiatives that local governments in the proposed zone will provide or establish to encourage businesses to locate in the proposed zone.  These may include economic or financial incentives or priorities, increased public services, improved infrastructure, structural rehabilitation and regulatory simplification and expedition."  ARS 41-1524.A.5.
    Also, the department of commerce shall annually certify "small manufacturing or small commercial printing businesses" that qualify for certain property tax incentives.  ARS 41-1525.01.A.
    However, "small" has a special definition.  In a county with so few people as Cochise County, a business "must invest at least the following amount ... in fixed assets ...
        "(ii) Cities and towns with a population of at least fifteen thousand but less than eighty thousand persons and in unincorporated areas of the county, one million dollars.
        "(iii) Cities and towns with a population of less than fifteen thousand persons, five hundred thousand dollars."
        ARS 41-1525.01.A.1.b.
    (My email about Enterprise Zones said that this would favor Sierra Vista, by requiring a million dollars startup money from people in the county, but only half a million from people in Sierra Vista.  I was wrong; since Sierra Vista only has about 40,000 people, the startup money requirements are the same for it as for unincorporated areas.  Thanks to Tricia Gerrodette for catching this mistake & pointing it out to me.)
    And "small manufacturing or small commercial printing businesses" means only businesses owned by women or racial minorities.
        -- "'Small commercial printing business' means a minority owned business or a woman owned business or a concern ...."  ARS 41-1525.01.N.8.
        -- "'Small manufacturing business' means a minority owned business or a woman owned business or a concern ...."  ARS 41-1525.01.N.9.
        -- "'Minority owned business' means an independently owned and operated business of which a majority of the business is owned by African Americans, persons of Hispanic or Latin American ancestry and persons of Native American, Asian or other minority origin or descent."  ARS 41-1525.01.N.7.
        -- "'Woman owned business' means an independently owned and operated business of which a majority of the business is owned by one or more women."  ARS 41-1525.01.N.10.
    In short, in some respects, the goal appears to be to deliver more government help to well-established businesses, not to help truly small businesses, and not to help on an impartial basis.
