What is the required minimum design density/area for protection of floor stacked, idle wood pallets...

For floor-stacked idle wood pallets, a design density of 0.225 gpm/ft² over a minimum design area is typically used for calculating water supply requirements. The larger area option (2,500 ft²) provides a more conservative approach to ensuring adequate protection.
