AN,
A quick geography lesson. City boundaries, School district boundaries and yes even ZIP Code Boundaries are not the same. The house on Moonflower is in Pacific Highlands Ranch (I believe). Technically it might be in the same ZIP and schoold district but ask anyone who lives in CV and they will say it is quastionable as to whether that is part of CV. Its like 92014 (Del Mar) CV neighbor to the west. There are many houses west of 5 that are in the SD City limits. Askthose owners and they live in Del Mar. Ask someone in the village or the colony areas of Del Mar and they would say you live in SD.
Rather than arguing semantics, it would be better for someone to come up with an example in the Heart of CV in one of the prime neighborhoods like Sonoma near Ashley Falls Elementary. That would be a real sign of decline in CV. I’m sure there are some there.
