  Here we study the pattern of neutrino oscillations emerging from a previously
proposed warped model construction incorporating $\Delta(27)$ flavor symmetry.
In addition to a complete description of fermion masses, the model predicts the
lepton mixing matrix in terms of two parameters. The good measurement of
$\theta_{13}$ makes these two parameters nearly proportional, leading to an
approximate one-parameter description of neutrino oscillations. There is a
sharp fourfold degenerate correlation between $\delta_{CP}$ and the atmospheric
mixing angle $\theta_{23}$, so that maximal $\theta_{23}$ also implies maximal
leptonic CP violation. The predicted electron neutrino and anti-neutrino
appearance probabilities indicate that the model should be tested at the T2K,
NO$\nu$A and DUNE long baseline oscillation experiments.
