Hi Joe:
It all looks great. I love the cutout/channel you've created for the waterway under the Hellgate bridges. I'm interested to see your progress as it unfolds.
One question I have is this: How did you cut your homasote? Did you take it outdoors and use a jigsaw? Or did you use a utility knife? Homasote is wonderful material once it's fitted and in place but it can be a royal PITA to work with before then. I'd love to hear your approach including what worked and didn't work for you.
