I was able to sketch out some more on this amid a conversation....
The Conversation took a turn into physics and how small and large bear a semblance due to their fractal nature.
The idea discussed was how shapes in nature are fractal. So building or land moving could also be done in a fractal manner. So the search for the "pattern" begins. If some one can come up with a particular pattern... like an icosa or dodecahedron one might be able to harness the fractal patterns we find in nature.

The Keyline and patterns,
"Keyline design is a technique for maximizing beneficial use of water resources of a piece of land. The Keyline refers to a specific topographic feature linked to water flow. Beyond that however, Keyline can be seen as a collection of design principles, techniques and systems for development of rural and urban landscapes..."

~ the dew seems to like pattern
Why not harness this trait to direct water to your keyline?
"The water collectors known as "dew ponds" were invented in prehistoric times, but the technology is nearly forgotten today. A few functional dew ponds can still be found on the highest ridges of England's bleak Sussex Downs and on the Marlborough and Wiltshire Hills, and connected to castle walls. They always contain some water that apparently condenses from the air during the night. Gilbert White described a dew pond at Selbourne (south of London), only 3 feet deep and 30 feet in diameter, that contained some 15,000 gallons of water which supplied 300 sheep and cattle every day without fail.
Investigations by UNEP (1982) and by Pacey and Cullis (1986) determined that the ponds do not catch significant amounts of dew, but actually were filled mainly by rainfall. Pacey and Cullis may, however, have confused dew precipitation with rainfall --- two different processes. The ponds may also collect fog..."
Then add an Airwell over your Dewpond?
~ sure why not?
"Depending on the temperature and partial pressure (p), air contains varying amounts of water vapor. When the partial pressure at a given temperature exceeds a certain level of saturation (saturation pressure, ps), then condensation occurs. The term Relative Humidity (RH) is the ration of the partial pressure and saturation pressure: HR = p/ps. The saturation pressure and the carrying capacity of air increases with the air temperature and pressure.
When a suitable substrate is available and its temperature is below the dew point, dew can form and be collected..."

Coppice Orchards in the wild
How to Graft Apricot Trees
(I recommend using a trio of peach, apricot and almond)
Graft On to mature....
Wild Peach And Wild Apricots
do this on steep slopes and cliffs or hedges or basically where deer and other animals cannot reach the branches.
Revisit seasonally to prune, pick and add beneficials (seeds, organic manures or dig small keylines for better water-soil retention.)
