John H - water, I think you are fortunate that those lovely sand dunes haven’t moved further inland .I think they covered Pontins Holiday Camp or is that wishful thinking on my part !? They certainly were part of my early childhood.
The sand dunes are nowhere as deep and high as I remember when on holiday up here in the 60's. The local authority has been selling the sand from the beach for decades for glass manufacture, which has over time lead to the dunes starting to disappear.
Beside rebuilding some of the sea defences, we have for the last 10 years or so where there are no sea defences an annual dead Xmas tree campaign. Were all the Xmas trees are collected by the council and planted sideways in a long line in the sand (forward of the current dunes,) to act as a wind break and to allow dunes to build up in the lee of the trees. Its proving quite successful the sand dunes are now much deeper and gaining height again. I do miss the rivers of sand blowing down all the local roads during heavy storms.
Pontins has all gone now, they have built 2 housing estates on the Pontins land with a clear area in between at the end of the runway. And those now living either side of the bottom of the runway are complaining of the aircraft noise, quite what they expected, I'm not sure.
