The letter from St Albans Council says:
"The Cemetery Information & Regulations state that a garden area not exceeding 3' wide and 1' deep is allowed in f ront of the headstone. In the recent past this rule has not been enforced and many people now have more of the grave personalised in a variety of ways. We understand why people wish to have a larger area and we have carried out an exercise to measure all of the areas which exceed 1' and feel if we now put a limit of 4' 6" on graves in section B, the majority of graves will be able to remain unchanged but still allow the cemetery to be maintained to the high standards expected."
