  We investigate a class of extra dimensional models where all of the Standard
Model fermions are localized to a single fixed point in an $S_1/Z_2$ orbifold,
and each species is localized with an exponential wavefunction with a different
width. We show that this naturally generates Yukawa hierarchies of the size
present in the Standard Model, and we find a set of model parameters that
reproduces the observed masses and mixings to experimental accuracy. In
addition, the dominant constraints, arising from flavor changing neutral
currents, are shown to restrict the compactification scale to be $1/R \ge 2-5
\tev$, which is a much less stringent constraint than in similar extra
dimensional models of the Yukawa hierarchy.
