Building on the flat clay plains near the Thames River is a very different challenge than developing on the sandy lake sediments around Wallaceburg. The town's western sectors, sitting on glaciolacustrine deposits, are prone to sheet erosion after heavy rain, while the older alluvial terraces near the city center demand a deeper look at subsurface washout. That is why a proper soil erosion analysis in Chatham-Kent is not a generic checkbox; it is the only way to know which parts of your lot will stay put during a 1-in-100-year storm. Without site-specific data, you risk designing drainage and foundations on assumptions that do not hold when the ground gets wet.
A soil erosion analysis in Chatham-Kent should always include field infiltration tests; the region's flat clay pan can mislead standard desktop models.
