(B) (1) Anchors and supports shall be designed for safe bearing loads on the soil and for an effective resistance to pullout amounting to a force 25% greater than the required resistance to overturning.
(2) Anchors and supports shall penetrate to a depth below ground greater than that of the frost line.
