• Outdoor Walk-In Cooler /Freezer Anchoring


Coastal jurisdictions have imposed new requirements for outdoor walk-in coolers and freezers (accessory Structures) in potential flood zone areas.  The new requirements adopted from ​​FEMA 60.3(c)(5) National Flood Insurance Program, require all new construction and substantial improvements shall be designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.

Approved Strapping

Determining quanity of anchor points that may be required is based on size of Walk-In Cooler /Freezer.  We use approved 1 - 1/4' certified galvanized strapping with minimum tensile strength of 4750 pounds.

Approved Anchor Point Methods
