How to install a fence on a raised bank

Installing a fence on a rised bank is installed pretty much the same way as any other fence, the only key differance is making sure you add on the extra length required for the drop. Normally the minimum depth a fence post should be in the ground is 2ft, so a standard 8ft post would be sufficient for a 6ft high fence on flat ground. This fence however was raised 1ft off the ground due to the ground level difference between the two gardens.  An extra long 9ft post was used for this fence to be sure that the minimum depth could be attained and the fence retains the same stability as one installed in normal conditions.
