For level sites, where should all setbacks be taken from?

In the context of Wisconsin Mound Soil Absorption Systems, setbacks are critical for ensuring proper functioning and protecting public health and the environment. For level sites, setbacks are typically measured from the toe of the mound. This is because the toe represents the base of the mound where it begins to transition to the natural ground, making it a crucial reference point for assessing the area around the mound.

Using the toe of the mound as the reference point is essential for determining distances to property lines, water bodies, and other structures, as it reflects the point where the mound has the greatest potential for water infiltration into the ground. By taking setbacks from the toe, it helps in mitigating the risks associated with surface runoff and ensures that the absorption system remains effective without interfering with neighboring properties or natural features.
