Urban Colonias

"Urban colonias in the Salt River Valley formed in one of three ways: as working-class neighborhoods on the fringe that filtered down from Anglos to Mexicans, as settlements based on real estate promotions in environmentally sensitive areas or on unproductive lands, known as “disamenity zones,” or as settlements forged by company-sponsored housing schemes" (Lukinbeal et.al. 2010, 12).
