@dalehileman,
I'm interested in what people like Rosborne say about this - he is top tier of people I listen to here.
My old boss would have been good at suggestions, more than I would be. He is both knowledgeable and inventive re a water catch., anywhere anytime. If we talk/write over the holidays, I may bring this up.
Also with another mentor, a teacher of mine from Japan, whom I consider out of sight smart re water and land but maybe not as close to california reality as is my old boss.
Me, I will say you need to provide river beds/channels and not just as decorative. Hey, consider hiring a landscape architect for a few hours. I'm one, but I stopped
quite a while ago.
New land arch folks know more now.
Consultation by varied professionals makes sense.
Don't just do it to skim ideas.
