Does a B-3 earth dike require geotextile placed under the stone in the channel?

A B-3 earth dike does not require geotextile to be placed under the stone in the channel. This is because the primary purpose of an earth dike is to manage water runoff and protect against erosion through the use of soil and stone materials. The dike's design relies on the natural soil properties and the stability provided by the compacted earth rather than relying on additional materials like geotextile to prevent soil erosion in the channel.

In certain situations, geotextiles are employed to enhance drainage or to separate materials, but for a B-3 earth dike, the standard specifications do not mandate their use. The focus is on ensuring proper construction techniques, such as compacting the earth and using appropriately sized stone, rather than incorporating geotextile, which is not necessary for the dike's function. Therefore, indicating that the statement is indeed false aligns with the established guidelines for constructing a B-3 earth dike in sediment and erosion control practices.
