That tapered off and, after a while, only the Dutton Lumber treatment facility remained; they manufactured classic CCA pressure-treated lumber. Quite some years after (IIRC) they went bankrupt and abandoned the facility, various buildings burned and the site seems to be slated for redvelopment into condos and suchlike.
The wisdom of siting condominiums along a tidal estuary, just a few meters above the current waterline and well below the future projected flood stage, seems dubious to me, but, then, I’m not a developer.
Anyhow, a recent ride across the Walkway showed that they’re sealing off the contaminated soil under what was once the lumberyard:
