🎯 What the Storm Surge Wizard Delivers

High-fidelity per-pixel flood depth grids derived from USGS 1m lidar DEMs — computed per storm scenario, clipped to your area of interest, and output as analysis-ready GeoTIFFs. Designed for jurisdictions that need defensible, deliverable flood depth maps — fast.

🗺️
Per-Pixel Depth Grids
Float32 inundation depth values in meters at native 1m resolution. Dry/above-surge pixels masked as NoData. Direct import to ArcGIS, QGIS, or hydrologic models.
📡
NOAA NHC Integration
Live storm track and surge advisory feeds from the National Hurricane Center. Real-time event tracking for active Atlantic and Gulf tropical cyclones.
📐
Configurable AOI
Submit any bounding box or polygon AOI. The engine clips to your jurisdiction boundary and processes only the area you need — scalable from a single parcel to a full county.
📊
Multiple Return Periods
10-, 25-, 100-, and 500-year recurrence intervals in a single job. Comparable scenarios for FEMA base flood, critical infrastructure, and resilience planning horizons.
🌊
Tidal + Surge Compositing
NOAA tide gauge integration for local mean sea level datum offset. Combines still-water tidal elevation with modeled storm surge for accurate coastal depth estimates.
☁️
Cloud-Optimized GeoTIFF
COG output for direct cloud hosting, tile server integration, or delivery to ArcGIS Online and ESRI Living Atlas workflows. Embedded CRS, datum, and metadata.

📦 Deliverable Outputs

Every job produces structured, GIS-ready deliverables — not raw data dumps. Ready for emergency management workflows, FEMA submittals, and resiliency reports.

🌀 Storm Return Period Scenarios

Compute inundation grids for four standard recurrence intervals — from routine tropical storm flooding to catastrophic Category 5 events.

10
Year Return Period
Cat 1 / Tropical Storm+
10% AEP — Minor to moderate coastal flooding. Routine preparedness baseline.
25
Year Return Period
Cat 2 — Moderate Surge
4% AEP — Moderate surge event. Infrastructure vulnerability screening.
100
Year Return Period
Cat 4 — Extreme Event
1% AEP — FEMA base flood equivalent. Regulatory and insurance standard.
500
Year Return Period
Cat 5 — Critical Infrastructure
0.2% AEP — Worst-case planning for hospitals, EOCs, and critical assets.

👥 Who Uses the Storm Surge Wizard

Built for professionals who need defensible, deliverable coastal flood analysis — not just a raw model.

🏛️ County & Municipal Emergency Management
Pre-positioned flood depth maps for evacuation routing, shelter siting, and ICS operations. FEMA-compliant deliverables for BRIC and HMGP grant applications.
🌊 Coastal Resilience Planners
Scenario-based inundation mapping for comprehensive resilience plans, vulnerability assessments, and capital improvement prioritization under FEMA BRIC and state resilience programs.
🏗️ Engineering & Environmental Consultants
Rapid flood depth deliverables for site feasibility, elevation certificate support, and project-level FEMA compliance — without a 6-month hydraulic modeling engagement.
📊 Insurance & Risk Analysts
Portfolio-level coastal flood exposure screening. High-resolution depth grids for underwriting, loss estimation, and property-level risk scoring.
🌐 State Agencies & GIS Departments
Statewide or regional surge analysis delivered as COG raster datasets. API-first design integrates directly into ArcGIS Enterprise, GeoServer, or ESRI Living Atlas pipelines.
🏫 Academic & Research Institutions
Reproducible, NAVD88-referenced depth grids for coastal hazard research. REST API enables programmatic access for model validation, compound flood studies, and publication-quality mapping.
