From what I have read about the new website, it is no longer required to complete all design prerequisites before submitting for Design Review (split review assumed).

We have been hung up on submitting EAp2 because a photovoltaic array is planned for one of our projects, but it won't be designed until far into construction. It would be really great to submit the other design credits and know where we stand (it's a super-complex project with an unusual LEED project boundary.)

So is it now true that we can submit for Design review and defer EAp2?
