Density doesn’t make for a good development, necessarily. It’s a combination of mixed-use (ability to walk to interesting businesses), access to transit, access to jobs, access to interesting aspects of nature (beach or mountains), interesting architecture, interesting people. Something that can’t easily be replicated in a planned community.
The best dense neighborhoods grow organically. To give an extreme example, would you rather live in a dense area of tower blocks with nothing on the ground floor, or somewhere like a less dense college town with houses walking distance to woods and/or a beach? (Think of Santa Cruz if you’ve been there.)
Personally, I’d pick a 2 bedroom condo or bungalow in North Park or one of the beach cities over this thing.
