IMO there is a huge amount of buildable Land in SD county,
(a lot of it not coastal true) but buildable none the less,
Seems to me even in SD city boundaries there is quite a bit left.
it may need re-zoning however.
I know it will never happen, but if camp pendleton ever closed that would be what 20-miles of coast line?
Even close to Downtown, there are quite a few area’s that it would make sense to be redeveloped in to much higher density at some point when the cost/rewards made sense.
