https://skyscraperpage.com/forum/sho...05&postcount=6
There are at least 56 projects over 300'. Of those, 32 are at least 400', 21 are at least 500', 11 are over 600' and 5 are over 700'.
There are also 10-12 other projects that are not listed because the height or floor count is not yet showing up on city documents. Several of those are likely to be in the 500'-700' range.
