^Thanks for reposting his quote here, I'm the one on there asking him about it
I just wanted to get him thinking, use a little Socratic Method. It just doesn't seem like a well thought out idea, I just imagine it being full of sleeping homeless people. In his recent reply he mentions Hance needing one big attraction or something that creates an identity for the park, but the Canyon would be the wrong way to go about that.
About the density, its never going to be hyper dense in that area. Even under the Urban Form code the East side of Hance Park is only zoned as tall as 80-90 feet, and at 218 dwelling units per acre. Thats solid density though and more than enough to keep the park active, though I would've preferred the lots directly adjacent to the park to be zoned up to around 150', but maybe that would've led to land banking...I suppose people can always apply for variances.
They key is thinking of the park almost as 2 halves, the Western half should be more of a recreational, traditional, neighborhood park. Open spaces, football, basketball, playgrounds, etc. The Eastern half if the more densely used urban park with tons of amenities, attractions and 8-ish story buildings flanking it on both the North & South sides.
