I almost always agree with bugs. About density at Quarry Falls, I think would be much better to have all high-density and mid-density housing and eliminate the low density ones.
Personally, I don’t like the large park and public facilities with gyms and such. Gyms can be in buildings integrated near housing rather than ugly freestanding structures. It would be better to have 3 and 4 story townhouses that front the street with no or very little HOA.
The Zocalo of Puebla, Mexico would be a great model for California — An arcade of restaurants and shops surrounding a square park with walkable housing nearby. Parking should be underground.
San Diego needs something creative, something different than the stucco sprawl and stucco strip mall that we have. Considering transportation costs, it’s high time re-invent ourselves.
