Multnomah Back Yard Section

In the back section we have fences all around which will allow us to introduce some helpful fauna: chickens, ducks, quail, and rabbits. We should also create welcoming habitat for mason bees, various birds, frogs, and beneficial insects.
The back yard slopes down from the house with a several feet of drop to the back fence.

I'm thinking the area behind the garage would be good for coops for the poultry, a greenhouse, and a place for an endless pool for us to exercise in.

The upper area would make a good Zone 1 for raised bed annual gardens. and a low deck off the back of the house (the current deck is too high which just gives a "better" view of the unsightly bits over the back fence into the commercial area of Sandy Blvd.)
If we add a swale before bellow the beds that will create an area for Zone 2 with perennials.
Then another swale and Zone 3 with fruit and nut trees, vines, and shade tolerant perennials.
One last swale before zone 4 with some tall growing evergreens: firs, coastal redwoods, and maybe a cedar. These will be as close to the back fence as we dare, layered with the tallest growing to the back (North) side.

Somewhere we need to work in a pond for the ducks, that will hopefully also be supportive habitat for frogs.

Along the fence on the East side it would be nice to set up some supports for climbing plants.

Excess rainwater, beyond what we can store, will be diverted into the swale system with level sills.

In the very North-East corner will be Zone 5, our little patch of wilderness.
