I spoke to the C.O.E.'s out there and they said there's a lot of clean up and debris removal to be done before parks can reopen. Said September is most likely scenario. One thing I thought was interesting is that the roads can't be driven on until they are completely dry underneath or the they will move and buckle. Of course, you know how funding and manpower is for them too.
