I can help! I live in that exact spot, directly across the street from Carmel Creek Elementary.
For me, the school itself hasn’t been a problem at all, I leave for work at 7ish, and the school is a ghost town, ditto when I return between 4 and 5. When I stay home from work, there is some noise during the school day, especially at 8:30ish and 2:30ish… For me it’s no problem, it’s the sound of happy kids playing, it’s nice.
There are sometimes sporting events over the weekend, and sometimes after school. This can cause the street to be all parked up, not an issue for residents who park in their garage.
I like the location becuase it’s easy for my kids to get to their various schools and it’s an easy walk to Del Mar Highlands Mall. There is some traffic noise at night being at the edge of the complex.
I’m happy to answer any other questions you have!!!
