I can't find the article I read on my phone, but it's going to be a "Right to Dream" academy with a full boarding school: https://en.wikipedia.org/wiki/Right_to_Dream_Academy
and they've committed to using as many of their home grown players as possible in the full MLS side. Also because they're so close to the border, there will be no issues with importing Mexican talent. Will be very interesting if they follow through with this and bring Ghanaian and Egyptian talent to SD as well.
Edit: Posted this before I saw the link above which is, in fact, the article I read.
