depth of clay

Asked September 6, 2018, 5:59 AM EDT

I'm wondering about possible average, minimum and maximum depth of the clay layer behind my house. The clay starts at around 18". I live in Blue Rock Manor, Alders Drive, Wilmington DE 19803. I am renting a backhoe to dig down under this layer to create a drainage pit / rain garden and would like to know how deep I might need to dig.
