RainLog makes that part obvious. We track rainfall at your sites and alert your team when an inspection is triggered. Documentation is ready before the deadline.
Request AccessWhether accumulation crossed the trigger at your assigned station isn't something most teams catch outside business hours.
They cross-reference NOAA precipitation records against your inspection timestamps. Station ID, accumulation, and timing all need to line up.
Qualifying events trigger the same inspection requirement whether your team finds out at 2 AM or Monday morning.
Under the NPDES CGP, post-storm inspections are required within 24 hours of a qualifying event (40 CFR 122.26). State permits may define different thresholds and timing.
Enter a site address. RainLog maps it to a nearby NOAA station. You see which station and how far it is.
NOAA precipitation data is checked continuously for every active site. No hardware. No sensors. No manual checking.
When rainfall exceeds your permit threshold, email alerts go out to your team with the site, station, accumulation, and deadline.
Each event produces a log with station ID, accumulation, timestamps, and threshold. Download or email to your team.
Every event is sourced from NOAA / National Weather Service precipitation data. Station ID and timestamp are included in every log. Verify the same data at weather.gov.

RainLog doesn't replace your forms, checklists, or process.
It handles one thing: knowing when a qualifying event happened and having documentation ready before the deadline.
NOAA's National Weather Service. Each site is mapped to a nearby station. Every alert and log includes the station ID, coordinates, and distance from your site.
Same NOAA precipitation data used by federal and state agencies. We show you exactly which station and how far it is, so you can evaluate the match.
No. RainLog handles rainfall detection, alerts, and event documentation. Your inspections stay the same.
Station ID, coordinates, 24-hour accumulation, threshold, event timestamp, alert timestamp, and inspection deadline. All sourced from NOAA.
When rainfall at your mapped station crosses the threshold, designated contacts get an email alert with the site, station, accumulation, and deadline.
Number of active sites. Pricing is being finalized. Early access participants get straightforward terms and input on structure.
Anywhere in the US. NOAA station coverage is nationwide. Thresholds and timing vary by state permit.
We show you exactly which station and how far it is. In metro areas, typically a few miles. In rural areas, distances may be greater. You assess the match.
RainLog is live and onboarding users directly. If you manage construction sites with SWPPP requirements, we'd like to hear from you.
We'll reach out directly to schedule a walkthrough and get you set up.
Available for construction sites nationwide.
