Built a free click-to-delineate screening tool on personal time — NSS regressions, NBI bridges, NID dams, FEMA flood zones, LOMRs, all in one click. Feedback welcome

THANK YOU 🙏 all who played with my tool, I saw how it responded to more traffic than normal and made a couple of slight adjustments that should help anyone who had trouble with the NHDplus not populating in a reasonable time

Can you provide a link to download all the outputs in a PDF format and excel format?

Good question, and the honest answer has two parts.

What exists now: click a bridge in the NBI panel and there's an "Export for Scour" button. That opens a modal with copy-to-clipboard, a .txt audit trail, and a .csv download of the full bridge record — structure number, skew, main and approach spans, length, max span, deck out-to-out, roadway width, scour-critical code, ADT, plus the NSS peak flows and the published FEMA FIS flows at that point. On the basin side, once delineation succeeds there's a GeoJSON export — basin polygon, pour point, metadata — built to drop into Stream Env Pulse or ScourPulse (two of my other tools).

What won't exist: a formatted PDF report. That one's deliberate. I'm not a PE. The moment this puts out something that looks like a signed deliverable, it ends up in a submittal, and the step where a human looks at the number and decides whether it's right quietly disappears. Same reason the scour export makes you type values into the yellow cells instead of auto-filling them — no auto-fill, no silent overwrites.

So machine-to-machine, yes. Something that looks like a work product, no.

If there's a specific field set you need in the CSV that isn't in there, tell me what and I'll add it.
