The property does not have a well. It is 1 acre and, historically, Escondido has been wetter than most of San Diego, so a rainwater harvesting system could be built eventually.
I am not too concerned about the future of water. We live next to an ocean. It’s not much more expensive to desalinize ocean water than to pump it from Northern California. We just need to build some desalinization plants. I’ll put solar panels on the roof to offset the energy cost.
