A. Ever been to the stylish Living Desert Zoo in Palm Springs? Despite it's small size it is incredibly enjoyable and well designed. A small zoo would be great for Encinitas and it would compliment the botanical gardens. An Encinitas zoo could specialize in breeding programs and petting corrals for cute fuzzy animals. Good for the kids!
B. Instead of the Eckes just building a bunch of ugly generic homes they could sell the lots individually. Then people could build custom homes and we could end up with an interesting eclectic neighborhood that would be a benefit to the town instead of the eyesore it is sure to be.
C. Since the land is zoned agricultural the Eckes could just sell it to another farmer. Who knows, maybe someone would want to grow something there? Perhaps something edible for a change?
D. A winery is a no brainer. I can't belive the Eckes haven't jumped on that one already.
E. Your idea here...
A big garden maze would be sweet even if horror movies have taught us that they are a bad idea.
