inches. Water moves freely through the upper part of the soil above the 

 compact layer, but movement is severely restricted in the compact layer. 

 Water tends to flow laterally over the compact layer, resulting in seep spots 

 on the lower slopes. Any artificial drainage considered for these soils should 

 be based upon the interception of the excess water above the compact layer 

 and the safe disposal of it so as not to create another drainage problem.
