GridGuard

GridGuard is a Utah-focused property due-diligence application for climate hazards, energy conditions, and solar opportunity.

Never commit API keys. The deployed application stores configured values as protected runtime secrets.

Current data status

• Census address geocoding: live official data
• NOAA/NWS grid context: live official data
• EIA electricity context: live official data when configured
• FEMA flood screening: demonstration pending authoritative GIS ingestion
• USDA wildfire screening: demonstration pending authoritative GIS ingestion
• Solar production: demonstration while the former NREL/NLR API integration is unavailable

Next milestone

Ingest authoritative FEMA NFHL and USDA wildfire polygons for Utah County, add parcel and utility-territory data, and calibrate scoring with domain experts.
