Sea Defences
The salt and fresh water marshes used to be very well protected. However the cost of replenishing the shingle spit grew too much for the village to sustain. Once the repairing stopped, it became easier for waves to get through; in 1953 a large storm, measured at 5.12 metres above ordnance datum (see North Sea flood of 1953) hit the North Norfolk coast and the shingle ridge was mostly destroyed. A further storm surge in 1978 measured 4.19 metres above ordnance datum and the protection measures confined flooding to the marshes and A149 coast road. The North Norfolk Shoreline Management Plan introduced by the Environment Agency has proposed a number of strategies in the light of continual erosion and predicted rising sea levels caused by global warming: these include Advance the line, Hold the line, Managed retreat and Do nothing. Even after extensive public consulation there is widespread local concern that the marshes, with their unique wildlife, will be irretrievably lost to the North Sea.

Famous quotes containing the word sea:
“Translation is entirely mysterious. Increasingly I have felt that the art of writing is itself translating, or more like translating than it is like anything else. What is the other text, the original? I have no answer. I suppose it is the source, the deep sea where ideas swim, and one catches them in nets of words and swings them shining into the boat ... where in this metaphor they die and get canned and eaten in sandwiches.”
—Ursula K. Le Guin (b. 1929)
