I want to know the answer to the following question:
Who developed New San Diego that was south of the first location?
All the background I'm provided with is that "In 1850, William Heath Davis promoted a new development by the Bay shore called "New San Diego", several miles south of the original settlement; however, for several decades the new development consisted only a few houses, a pier and an Army depot.". Is that enough to answer the question?
Answer: yes
