The pole depth formula commonly used in Outside Plant (OSP) design is based on ensuring that a pole is adequately anchored to withstand environmental factors such as wind loading and ice accumulation. The standard practice is to set the depth of the pole in the ground to provide stability and durability over time.

The formula of 10% of the pole height plus 2 feet is established to ensure that the pole is deeply anchored while taking into account the added stability required for various conditions. This depth helps counteract forces acting on the pole and minimizes the risk of it becoming dislodged or toppled. The 2-foot addition recognizes the complexity of the soil conditions and potential above-ground stresses that the pole may encounter, ensuring a more robust installation.

In contrast, alternative formulas would not adequately address the required stability for types of poles used in OSP applications. The percentages and additional footings in the other options do not align with industry standards that have been developed through experience in the field. This ensures that poles maintain necessary structural integrity over time and under various environmental stresses encountered in outside plant installations.
