As many as possible. That one on the corner is worthless but the other ones are great. It doesn't sound like they will build on the other parks other than part of arbor and the one on the corner. I a huge proponent of maximal green space because that adds a certain quality that buildings cannot. There's a reason NYC did the hi line. I really like the design proposal for arbor park because it isn't just plopping a building down on the entire site footprint. They were very considerate of the existing park and incorporated it into the new plan.
