La Costa Greens and Ridge are not La Costa Valley and they have their own HOA’s and amenities. They are newer and by all accounts very nice. The big difference is school districts. I have a feeling a lot of these residents send their kids to private schools at least for middle and high school (not even sure what the middle school is).
La Costa Oaks is yet another newer development and it is part of the same school district (Encinitas/San Dieguito). My only concern with the newer developments is that a lot of the speculation and toxic loans are probably hidden in some of these neighborhoods which were built right as prices peaked 2004-2006. Some of it has already been shaken out through foreclosures, etc. but it’s difficult to know for sure.
Santa Fe Chritstian is a very good school in Solana Beach and goes from elementary through High School. We have friends that send their kids there and they love it. The school bus makes a stop in La Costa Valley.
