I'm not really the target user (eh, I could be an activist?) but I tried looking for EIS's of a controversial sewage treatment plant near my home on these various tools. I thought it would inform the discussion, but my results are inconclusive.
Searching "Environmental Impact Statement" and related terms in Google Dataset Search gave me nothing (they do have some EISs, though):
I didn't have to specify EIS when seaching our prototype b/c that's all it does (an asset?). I got results, but none of them relevant to what I actually wanted. I'm aware we don't have a complete database there, so can't really read into that. (I also searched "Woodinville" by itself, which returned only two records):
Ultimately, I tried searching the relevant terms in a Google Search, and immediately found what I was looking for:
Urgh. I'm not really sure what to read into that.
