StormGuard Pro is the all-in-one stormwater inspection app built for construction site compliance. Designed for inspectors, site managers, and environmental professionals, it simplifies the entire inspection process from start to finish. GUIDED 5-STEP INSPECTION WORKFLOW Complete thorough inspections every time with a structured process: header data, area inspections, BMP controls and maintenance, notes and summary, and digital signature certification. Never miss a required field again. GPS-POWERED WEATHER INTEGRATION Fetch current weather conditions with one tap using your GPS location. View 5-day forecasts, track 7-day rainfall history, and automatically detect post-storm inspection triggers based on your permit thresholds. Weather data sourced from the National Weather Service and Open-Meteo. 50+ STATE PERMITS SUPPORTED Pre-configured for Colorado COR400000, California CAR10000S, Texas, Florida, New York, and construction general permits across all 50 states plus federal EPA CGP. Each permit includes the correct inspection frequencies, post-storm thresholds, corrective action deadlines, and certification language. TEAM MANAGEMENT & REGIONS Invite team members, assign roles (inspector, manager, admin), and organize projects by region. Managers get a dashboard to oversee inspections across their team. PHOTO DOCUMENTATION Capture and attach photos directly to inspection areas. AI-powered analysis identifies BMPs in your photos automatically. Track before and after photos for corrective actions. CORRECTIVE ACTION TRACKING Document inadequate BMPs with severity levels, due dates, and resolution tracking. View all open corrective actions sorted by priority. Mark items resolved with one tap and attach completion photos. PROFESSIONAL PDF REPORTS Auto-generate branded inspection reports with your personal or organization logo, ready for submittal. Share reports instantly via email or any app on your device. INTERACTIVE CALENDAR Color-coded calendar shows inspection due dates, corrective action deadlines, and post-storm events at a glance. Never miss an inspection deadline with overdue alerts. BMP REFERENCE LIBRARY Searchable database of Best Management Practices organized by category — erosion control, sediment control, and more. Quick reference during inspections. POST-CONSTRUCTION CONTROL MEASURES Inventory the permanent structures an MS4 program oversees — extended detention basins, sand filters, and porous landscape detention — and score each component against the inspection form the municipality actually uses. Record the maintenance performed, which parts it was done to, and the effort it took. Generate the annual inspection and maintenance submittal from the records. ADDITIONAL FEATURES - Dashboard with quick project stats and overdue alerts - Multiple project management with permit details - Digital signature capture for inspection certification - AI-assisted inspection note generation - Custom logo upload for branded reports - Password reset and secure authentication - Haptic feedback and smooth animations
