So, New York City can fit over 8 million people onto 301 square miles (which includes an 843 acre park), but you don’t have the vision for how San Diego could add any more housing beyond what our current 1.2 million or so (San Diego City) residents need inside our 324.3 square miles?
If it needs to happen… it will. What others are telling you is that the “need” is not there right now. Based on MANY factors, it is unlikely that this is a real problem for many, many years still.
Others are right though. San Diego had better do A LOT to increase it’s business base, or that “need” will never materialize. (Personally, I’m good with it NOT happening).
