GIS workspace
Stormwater is spatial. Your compliance software should be too.
NPDESTracker treats spatial context as a first-class part of the compliance workflow. Outfalls, BMPs, sites, and incidents live on a live map alongside the records that document them. The product is built to coexist with the GIS your agency already runs, not replace it.
01 · Live map
Your stormwater inventory, on one map.
Most coordinators carry a mental map of where their outfalls, BMPs, and active investigations sit. NPDESTracker puts that map on a screen. Every spatial record in the program is on it, color coded by status, with the underlying record one click away.
- Outfalls, with classification, receiving water, and inspection history
- Structural BMPs, with type, ownership, and maintenance status
- Construction sites, with active disturbance status and inspection cadence
- Municipal facilities under MCM 6 with their housekeeping records
- IDDE incidents, from complaint intake through closure
- Sample and screening locations tied to dry weather and wet weather observations
02 · Coexists with ArcGIS and QGIS
Designed to live alongside your existing GIS, not replace it.
Most public works teams already maintain their authoritative GIS in ArcGIS Online, ArcGIS Enterprise, or QGIS. That work belongs there. NPDESTracker is the operational layer for the compliance program that runs against that data, not a duplicate system asking your GIS staff to re-key everything.
Outfalls, BMPs, and sites can come in from your existing layers as GeoJSON or shapefile. Coordinates and per-feature attributes are preserved. When you need data back out for a state agency submittal or for QA inside ArcGIS, exports run in the same standard formats.
We do not claim a partnership with Esri or any other GIS vendor. The interoperability story is built on open file formats and standard coordinate systems, which is what most municipal GIS workflows actually run on day to day.
03 · Standard formats in, standard formats out
Data moves cleanly in both directions.
The interop story is intentionally simple. Open formats, standard coordinates, no proprietary middleware to maintain.
- Imports GeoJSON and shapefile so existing ArcGIS or QGIS layers come in directly
- CSV import with latitude and longitude for spreadsheet-tracked inventories
- Exports in GeoJSON, shapefile, and CSV for state agency submittals or QA in your primary GIS
- Standard WGS84 coordinates stored on every spatial record
- Per-feature attributes preserved on import and export so layer fidelity stays intact
04 · Field workflow
GPS and photos on the record they belong to.
The map is not a separate product. Inspectors capture coordinates and photo evidence as part of the inspection itself, on whatever device they have in the truck. Office staff see those records on the map and inside the inspection list the same way.
- Browser GPS captures coordinates the moment an inspection or incident is logged
- Photos attached to a record carry the location they were taken at
- Inspector panel shows address, parcel info, and linked records without leaving the map
- On-map filters by status, classification, or open investigation
- Switchable basemaps for street, topographic, and satellite views
The full field inspection workflow is documented on the inspections page.
05 · BMP inventory mapping
A live BMP inventory you can actually maintain.
Structural BMPs are some of the hardest assets for a small program to keep current. They sit on private parcels, ownership shifts, and the spreadsheet that tracked them often does not survive a staff transition. NPDESTracker keeps the BMP inventory on the same map as the rest of the program, so the type, ownership, last inspection, and maintenance status are visible the moment you open a parcel.
Imports come in from your existing GIS layer or from a CSV with coordinates. Inspections and maintenance records attach directly to the BMP, which means the MCM 5 section of the annual report is reading from the actual asset list rather than a year-end reconstruction.
06 · What this is, what it isn't
Honest about scope.
We would rather be useful inside a clear scope than oversell a generic GIS story.
What this is
- A GIS-aware compliance workspace built around your MS4 program
- Designed to coexist with the GIS your agency already runs
- Spatial context on every site, outfall, BMP, and incident
- Standard format imports and exports so data moves cleanly in both directions
What this is not
- A replacement for ArcGIS Online, ArcGIS Enterprise, or QGIS
- A surveying tool or a CAD system
- A general-purpose GIS platform for non-stormwater work
- A claim of partnership with Esri or any other GIS vendor
