Continuous & event simulation
Run a single design storm or thirty years of recorded weather. Same model, two horizons.
Features
A toolkit calibrated to field reality.
The record layer and the computation, in one platform — the inspection, the model behind it, and the deliverable a permit asks for. Here's what that looks like in practice. Screens are illustrative; see a live demo for what ships today.
01 — Operations
One screen for the whole program.
Sites, risks, permits, and weather on a single cartographic canvas. The map is derived UI over your records — every pin, badge, and number traces back to the same model.
- Live vitals: runoff modeled, open risks, inspections, compliance
- Open-risk triage with severity and downstream context
- Portfolio distribution at a glance — normal, watch, warning, critical
02 — Compute
The math, sourced and reproducible.
Pick a design storm and the Rational Method runs with every term traced to a public dataset — C from land cover, i from Atlas 14, A from the parcel. Re-run the same inputs and you get the same answer.
- Rational, SCS / NRCS curve number, TR-55 — the established toolkit
- Design storms from NOAA Atlas 14, or decades of recorded weather
- Every output carries its method, inputs, and governing citation

03 — Risk
Risk you can watch move.
A portfolio risk index that tracks the program over time, not a static score. Built to separate the high-severity tail from the mean so you can see what's actually trending — and prioritize the next inspection day.
- 90-day trend across the whole portfolio
- High-severity share split from the mean
- Designed to prioritize routes by where risk is rising

04 — Records
Every site, one register.
The full inspection and record layer — filterable, searchable, and tenant-scoped. Status, condition, last visit, and watershed in a single dense table, with the map kept in sync.
- Filter by status, watershed, permit, or last-inspection window
- Condition and status badges generated from program data
- Bulk export, schedule, and audit trail built in

05 — Field
Inspection, done once.
Native mobile, fully offline. Photos are read for deficiencies on device — the finding is advisory, surfaced for the inspector to confirm or override before it becomes a compliance record. Everything syncs on reconnect.
- Offline-first capture with deterministic, conflict-safe sync
- On-device deficiency flagging — always inspector-confirmed
- Integrity metadata captured with every submission

06 — Everything else
The rest of the toolkit.
Benefit-first, method-light. The depth is in the methodology — and on every number the platform returns.
Automated watershed delineation
Drainage basins and flow paths derived from terrain, not hand-drawn.
Photo-aware inspections
Field photos are read for deficiencies on the spot, so problems get flagged before they leave the site.
Automated permit verification
Coverage, deadlines, and obligations checked against the governing rules, nationwide.
Pollutant load & receiving-water context
Loads disaggregated by pollutant, attributed to the right downstream water and its impairment status.
Methodology on every number
Each computed output carries its method, inputs, and the governing citation — so it stands up when someone asks how you got it.
Native mobile, full offline
Field-first, with everything syncing when you're back in range.
Reporting & deliverables
Permit reports, stakeholder maps, and engineering exhibits export in the formats your reviewers require.
