Piedmont Clay Soil
<0.2 in/hr
Clay drainage rate
Union County sits on the Cecil clay soil series — dense red clay that drains at less than 0.2 inches per hour. After any significant rain, water pools against Weddington's estate foundations and wicks upward into crawl spaces for days. The large, professionally landscaped lots in communities like Providence Woods South and Stratford on Providence can actually concentrate runoff toward foundations rather than away from them.
