What StormGrid Does

From raw terrain data to regulatory deliverables

Engineering firms lose weeks to manual floodplain work — clipping rasters, re-running models after minor edits, formatting reports to agency specs. StormGrid automates the deterministic parts of that pipeline so your licensed engineers focus on the judgments that require their expertise.

Request Early Access
Automated DEM Preprocessing
Ingests LiDAR and 3DEP DEMs, applies hydrological conditioning, and burns stream channels without manual intervention.
HEC-RAS Model Generation
Constructs 1D/2D HEC-RAS geometry files from processed terrain, configured to FEMA and state agency standards.
Floodplain Delineation & LOMA Support
Generates SFHA boundaries, BFE profiles, and cross-section data structured for MT-2 LOMA/LOMR applications.
Audit-Ready Report Export
Delivers stamped PDF reports, GeoJSON/Shapefile exports, and model archives formatted for agency submission.
GIS Integration
Connects to ArcGIS, QGIS, and web map services. Outputs are projection-aware and CRS-correct by default.
