Cass County clay plus open wind on the new unsheltered developments.
Raymore's planned communities are often built on former farmland — fertile on top, heavy clay underneath. Many lots have significant grade changes, and the newer developments lack wind break to the south. Combined with freeze-thaw cycles, posts set shallower than 36 inches lean or heave within a few seasons. Our install standard is 36 inches in wet-poured concrete with a bell-bottom footing. Every post. Every time. From Olathe, we work across the state line to Raymore without changing the standard.
