Re last undeveloped lots in Encinitas, I nearly purchased a plant nursery undeveloped lot in 2011. I recall it was bordering the 5 and maybe .6 acres, I forgot which side.

Basically my screen on zillow was large lots and low price near the coast.

I got a large underdeveloped lot in OB instead. The correct answer in retrospect was “¿Porque no los dos?”
