Welcome to Phoenix

The Valley of the Sun is among the fastest growing, most dynamic economies in the nation. Home to Arizona State University; Intel, Amazon, State Farm, and other industry leaders have found a home in Phoenix. And in the midst of this rapidly evolving community, we are developing the infrastructure and creating the connections that make this growth sustainable.

Our impact can be seen at Phoenix Sky Harbor Airport, as well as the Valley Metro Light Rail, welcoming new arrivals and carrying them to the rest of Phoenix. Our work can be tasted in our drinking water and the crops we grow. Our work protects our environment while growing neighborhoods across the Valley.
