Rock Ht. (left and right) represents the total height measured from finished grade at centerline. It includes all layers that have a Bedrock ground type assigned (for more information see Ground Types Editor). Stripping is always excluded.
Below are examples of Rock Height calculations.
Example: Rock Ht. calculation when layer 3 only is a bedrock ground type
Example: Rock Ht. calculation when layers 2 and 3 are bedrock ground types
