What you’re up against.

Stormwater compliance gets harder as you scale. Here’s where teams like yours feel it most.

!

Many lots, many phases

Dozens of small sites moving at different stages, all under one permit.

!

Inconsistent inspections

Different crews, different habits — and uneven records to show for it.

!

Compliance that won’t scale

What works for one subdivision breaks down across a full pipeline.

SWPPP compliance for builders

Stormwater compliance built for residential developers.

Homebuilders and residential developers operate under the same EPA Construction General Permit (CGP) and state NPDES stormwater permits as the largest infrastructure contractors — but the work looks completely different. Instead of one large site, you're managing dozens of small lots that move through grading, utilities, vertical construction, and final stabilization at their own pace, often all under a single permit. Rain Event Tracker was designed for exactly that reality: repeatable SWPPP inspections that scale across every lot, phase, and subdivision without adding office overhead.

Never miss a qualifying rain event

Most construction stormwater permits require a SWPPP inspection within 24 hours of a qualifying rain event — typically 0.25 inches or more in a 24-hour period, though your threshold may differ by state and permit. Rain Event Tracker pairs each of your sites with its nearest NOAA precipitation station and monitors rainfall continuously. The moment a lot or phase crosses its threshold, the responsible superintendent or crew lead is notified automatically, so a storm that rolls through overnight never turns into a missed inspection window or a stormwater violation.

Standardize inspections across every crew

When different crews follow different habits, your records show it — and inconsistent documentation is exactly what auditors and regulators look for. With standardized digital inspection forms, every crew on every lot files to the same system, capturing BMP condition, erosion and sediment controls, corrective actions, and photo evidence the same way every time. AI photo analysis turns a quick snapshot of a silt fence, inlet protection, or stabilized entrance into a drafted, report-ready finding you can review and approve in seconds.

Records that stay reporting-ready

Because every rain event, inspection, and corrective action is logged year-round against the authoritative NOAA record, your records and audit packages stay export-ready. When a jurisdiction, lender, or permit renewal asks for a complete compliance history on any lot or subdivision, you can export defensible documentation on demand — and the optional Annual Report Assistance add-on streamlines the annual report filing itself.

FAQ

SWPPP questions from builders.

Common questions about stormwater compliance for homebuilders and residential developments.

What is SWPPP software, and why do builders need it?+

SWPPP software digitizes the inspections, rain-event monitoring, and recordkeeping your Stormwater Pollution Prevention Plan requires under the Construction General Permit. For builders managing many lots and phases at once, it replaces paper forms and spreadsheets with one system that triggers inspections automatically and keeps a defensible, audit-ready record for every site.

How does Rain Event Tracker handle subdivisions with many lots?+

Each lot or phase can be tracked individually while rolling up into a single subdivision view. You see rainfall, inspection status, and corrective actions down to the phase level, so you always know which parts of a development owe an inspection after a storm — even when grading, utilities, and vertical work are all happening at once.

What counts as a qualifying rain event?+

Under most construction stormwater permits a qualifying rain event is 0.25 inches or more of rainfall in a 24-hour period, which triggers an inspection requirement. The exact threshold varies by state and permit, so Rain Event Tracker lets you set the threshold for each site and notifies the right people the moment NOAA data shows it's been crossed.

Where does the rainfall data come from?+

All precipitation data comes directly from NOAA, the authoritative weather source recognized under the Construction General Permit. Each site is paired with its NOAA station and rainfall totals update in real time, so your inspection triggers and records rest on data that holds up to audit.

Can different crews use the same inspection process?+

Yes. Every crew completes the same standardized digital forms from any phone or tablet in the field, so inspections are consistent across lots, phases, and superintendents. That consistency is what makes your documentation defensible when a regulator, lender, or auditor reviews it.
