Garage opening
Flood path: Driveway runoff and street pooling reach the garage threshold before interior spread.
Homeowner concern: Water enters through the garage first during heavy rain or surge push.
- Low threshold relative to driveway grade
- Door seal compression under hydrostatic pressure
- Wide span requiring hundreds of sandbags per event
Visual Fit Check with driveway-to-threshold photo → measurement review for panel count.
Front door threshold
Flood path: Shallow sheet flow crosses the door sill during summer storms or king-tide push.
Homeowner concern: Repeat nuisance water at the front entry without whole-home inundation.
- Exterior grade at or below finished floor
- Threshold gap under wind-driven rain
- Slow sandbag deployment on narrow entry
Visual Fit Check with threshold and both jambs → door-specific measurement review.
Side door threshold
Flood path: Side-yard grading sends water to utility or walkout doors before garage exposure.
Homeowner concern: Side entry floods while the front of the house stays dry.
- Patio or side-yard pooling
- Utility door with minimal seal height
- Secondary opening overlooked in storm prep
Photograph side threshold line → include in multi-opening assessment scope.
Sliding glass door
Flood path: Wind-driven rain and coastal push enter at slider track before interior damage spreads.
Homeowner concern: Lanai and rear slider take water during storms while garage stays dry.
- Track drainage overwhelmed by wind-driven rain
- Low sill relative to lanai or patio floor
- Large glass span with limited sandbag stack height
Visual Fit Check with track and threshold visible → slider measurement review.
Lanai enclosure opening
Flood path: Rain bands push water under lanai base and through door transitions to interior.
Homeowner concern: Lanai floods repeatedly; unsure which line to protect first.
- Screen enclosure base channel leaks
- Multiple panel lines without coordinated protection
- Repeat seasonal deployment burden
Rank openings by repeat exposure → Visual Fit Check per priority line.
Commercial entry
Flood path: Street-level pooling reaches commercial entries during rain bands and surge windows.
Homeowner concern: Business needs repeatable deployment without closing for sandbag labor.
- Wide storefront or entry with ADA thresholds
- Limited staff for sandbag deployment before storms
- Inventory and equipment at risk at grade level
Commercial assessment for entry width, post mounting, and deployment staffing plan.
Warehouse roll-up door
Flood path: Loading apron and dock area sheet flow reaches roll-up threshold.
Homeowner concern: Warehouse or large bay door cannot be sandbagged in time before landfall.
- Very wide opening requiring extreme sandbag counts
- Seal failure at bottom rail under pressure
- Loading area drainage tied to door line
On-site width and height measurement → engineered panel layout for wide spans.
Loading dock
Flood path: Parking lot sheet flow and surge push enter at dock lip and bay doors.
Homeowner concern: Dock flooding damages equipment even when main structure elevation is adequate.
- Dock level below parking lot during surge
- Multiple bay openings without coordinated plan
- Drain backup at dock pit independent of barrier line
Assess dock drainage first → scope barrier lines per bay after water path review.
