By obtaining a data set comparable in size and nature to recent generations of local surveys, the DEEP2 Galaxy Redshift Survey has made possible the study of the relationships between galaxy properties and local environment at z 1. I will present results from DEEP2 focusing on the evolution of the color-density relation at intermediate redshift (0.4 < z < 1.3); we find strong evidence that the build-up of galaxies on the red sequence occurred preferentially in overdense environments over that period. I will show that massive clusters of galaxies do not drive these results; rather, it is group-like environments which dominate. If time permits, I will discuss the physical mechanisms responsible for the quenching of star formation at z 1, including the role of AGN activity and quasar feedback. Lastly, I will present the discovery of a population of bright, blue galaxies in dense environments seen at z 1 but not locally. These objects are likely to be precursors of some of the massive, red galaxies seen today.
