Wow, that's quite a flood! If it were me, I'd eliminate the raised beds (and the extra work they entail), keep the arborvitae and cluster any other shrubs you want to save at their feet. Then, maybe a small flower garden along the fence is you want one.

It looks to me like a few fruit trees, berry bushes and a vegetable garden could easily occupy this space. If you don't want to save shrubs, that'd be the first thing to clean out, including by the road (not the daylilies.) Do you have a picture of how it looks today? And one that shows how it relates to the house?

Thanks Yarvaark for the input. The space is across the road from the house. The house sits up on a bank on the opposite side of the road relation to this fenced area, so it's not really "connected" to the house at all (I took some of those photos from my upstairs bedroom window). A mill race runs behind the garden fence and then it's all wooded area leading down to a creek (hence the flooding). The bushes in front of the fence are gone already with the exception of the Witch Hazel tree.

Basically it all looks like photo #3 today, minus the wooden frames around the beds, and the back row middle bed is completely gone now. Otherwise, it looks pretty much the same.

I don't see the point of raised beds and would just do a normal garden in the ground, for whatever size you want to make it, and devote the rest to orchard, with a hedge of berries across the back. I'd either make a bed under the fence, if I wanted to plant something on it, or I'd run a permanent, wide mowing strip under it so as to keep it free of grass and make mowing easier. Too hard for me to show it, but mulch squares or strips below the fruit trees.

Wow, that's awesome! Thanks so much Yardvaark! I haven't been able to visualize anything new in that space at all, this is so helpful!
