Oh dear...
That would be an insulting use of that site. We don't need a suburban apartment complex in one of the most important sites in Downtown IMO. The only thing I like is the park roof but the rest of it is a no no.
After looking at the website, I'm hoping this isn't what is actually planned. For one thing they have a tennis court where the Waterline is. Nor to they have the Travis Tower just park space. Waller will not look like that either.
