Depending on what market you are in, the local authority having jurisdiction may require you to have flood vents in your parking garage door to allow water to flow in and out in the event of a dangerous flood or storm.
What Are Flood Vents for?
Hydrostatic pressure caused by rapidly rising floodwaters can easily destroy the average commercial or residential garage door. Flood Vents protect buildings in floodplains by preventing water pressure buildup that can destroy walls and foundations. These vents can be insulated and non-insulated.
