I've now received their proposed planting plan. In our really wet areas (i.e., standing water) they will thickly plant live-stakes of various willows, crabapple, ninebark, dogwood, and twinberry. These will be planted very close together with a high expectation of loss. In the outer areas where water is not as prevalent, they will plant potted ash, cascara, vine maple, serviceberry and ribes. I presume these will have a better chance of survival. Hopefully this fall will be planting time. Should be an interesting project.
