Looks like you could almost build another Carlsbad between Melrose and El Camino.
Another thing to think about is that an area can only support what it can support economically. There is generally going to be a balance between business and residential. If you are completely built out (or too expensive), don’t expect business to grow past that point, where would they find employees? On the other hand, if you lose some of your businesses, or business doesn’t grow, don’t expect residential to hold it’s value either as people move out in search of work elsewhere.
