A retaining wall, in the context of manufactured homes, is defined as a barrier that is specifically designed to hold back soil or other materials, particularly when there is a sudden change in elevation. The definition highlights the importance of the wall being capable of retaining lateral loads, which means it must be strong enough to counteract the pressure exerted by the earth and other materials it is holding back. In this context, the specification of a minimum differential height of 18 inches provides a clear standard that allows for the effective management of soil shear forces, making such walls critical in ensuring the stability and safety of manufactured homes built on slopes or uneven terrain.

The purpose of a retaining wall extends beyond mere aesthetics; it serves a vital functional role in maintaining the position of ground material, thus preventing erosion and potential damage to the home structure. Consequently, this barrier plays a crucial role in the overall site development and planning of manufactured homes, particularly in areas where topography poses challenges.

Other options, while they touch on different aspects of construction or landscaping, do not convey the essential characteristics of what a retaining wall is intended to achieve in this context. Therefore, the definition provided accurately reflects the purpose and function of a retaining wall within the manufactured home setting.
