Though he said the exact location hadn’t yet been determined, NFL vice president of special events Frank Supovitz revealed that the Super Bowl XLV host city itself (Arlington, not Dallas) is where the league will build a Youth Education Town (YET Center). They’ve been creating places like this as part of their annual Super Bowl investments since 1992. There are currently 15 in the country, including one in Honolulu (traditional site of the Pro Bowl). Generally these are put into low-income neighborhoods.
The YET centers house afterschool programs including tutoring, mentoring, and recreational activities. The NFL pledges $1 million for the YET, with the rest needing to be matched by local donations. I’m sure the Host Committee can help you out if you’re interested in contributing to the project.
