TidalBoundary

In England and Wales, these tide lines will be the levels of mean tides, i.e. of a tide between a spring and neap tide. In Scotland, the tide lines are those of mean spring tides. In places where there is no Foreshore (e.g. vertical cliffs), the TidalBoundary is classified as the 'High Water Mark'.
