What Leaders Said
“We’ve got a couple million square feet of retail [in the Southeast Valley] within five miles of the site and seeing the performance and demand from retailers in those projects it really kind of led us to where we are today,” said David Larcher, Vestar president and CEO. “[Legacy Park] will have a profound impact on the quality of life in the Southeast Valley.”
“Legacy Park is not just another development. It is a thoughtfully designed community that will bring lasting value and lifestyle to the East Valley,” said Andrew Cohn, principal of Pacific Proving. “We have waited for the right timing, the right opportunity, and the right partners and that moment is now.”
