I'd imagine that the gradation/elevation differences in the current lot would require them to close and rip out whatever portion they start with. I would expect them to start with the sections closest to Turkey Lake Rd. and Vineland, and that's a pretty good grade and elevation difference to be working with. When it comes to the sections closer to the TM security gate and HR, there's a serious dip for drainage and a section that tends to flood when weather is less than ideal, so not likely to be able to build over and then do a bottom level. Foundation and support work would likely require serious regrading and soil work for those kinds of loads in those areas with the current conditions of the lot.
