Hey Tom,
I agree, there are many advantages with this much water. We are planning on lots of systems with subtropical, aquatic loving plants throughout. It is quite exciting. I can upload some photos to give more ideas.
Yes, keeping the roots dry is very important which is why I am here asking questions. We've already raised the area quite a significant amount to protect trees like mango, lychee, jackfruit and the others that do not like having wet feet. This is why I am trying real hard to make sure we are making the right moves with whatever it is that we are doing. We have massive amounts of opportunities for microclimates in the entire site, which is very exciting.
I am still wondering how to collect the water safely in a flat land that will protect the water sensitive trees, provide habitats for aquatic loving plants, keep mosquitos to a minimum, reduce/ eliminate piped irrigation systems, and keep our roads and structures from flooding (and everywhere else that we don't want flooding).
Did I mention we get 7,360,200 gallons of water ever year?
Thanks everyone!
Jason
