Hello Allison, 

First off, I am so sorry to see that this happened to you- your garden looks beautiful! I do think that it is smart to move your vegetable garden as well as any edible landscape plants to parts of your yard that will not be within the flood zone. 

Here are a couple of resources on what to do with edible plants that came into contact with flood waters and how to clean up lawns and ornamental plants in the aftermath:

On to ornamental landscape plant recommendations. If the flooding subsides within 24 hours when this does happen, I think that you have a lot of options for this area. Most shrubs and trees can handle this, and it appears that there is a healthy line of trees and shrubs in the distance in your photo.

I know that a rain garden is not necessarily what you are trying to do here, but on pages 22 and 23 (Table 4) of this manual there are a lot of good plant suggestions that can handle wetter soil. I think that this is a good place to start for plant suggestions in this area.

I hope this helps as a good starting place for planning your new garden! You can certainly plant more things that are not on this list there as well, you will need to read the tags carefully and make sure that the selections that you make can handle full sun as well as wetter soil at times.
