There are at least two clues that housing has been considered on that land for awhile.
The first clue is La Harira Court. It is indeed a cul-de-sac on the end away from the vacant land. It is a dead end where it runs into the vacant lot. When a normal street just ends suddenly (no cul-de-sac), it usually means that someone intends on extending that street at some point in the future.
The second clue is more subtle but it is still there. The shots of 8561 Celtic show a decent view over the pool, across the vacant land, and to the mountains off in the distance. But you’ll notice the owners have decided to line bushes and trees that grow tall up against that fence line and it is slowly but surely obscuring the view.
Normally, folks with a view preserve it at practically any cost. Only those wishing to block an undesireable view line up bushes and trees like that.
That leads me to believe they’ve known for quite some time that something would be built on that land eventually.
