Have your say

I was involved with the installation of the original timber zig-zag groyne scheme at Hunstanton South Beach and the objective of the scheme was to encourage the build-up of beach material on the foreshore.

The built-up material helps to dissipate energy from the waves in times of storm and this reduces the force of the sea acting against the wall, promenade and wave wall at the back of the promenade.

In a letter to the Lynn News dated January 8, Chris Smith was concerned that the beach sand has built up to nearly the same level as the promenade in some places and he suggests that this could cause flooding.

Residents might have been concerned in that Chris doesn’t indicate why it could cause flooding, but if he is saying that it is because the sand has covered a surface water/flap valve outlet arrangement built into the sea wall then he has a very valid point. This outlet arrangement should be kept clear. The built-up beach does not in itself present a problem. The tide simply “comes in” to a slightly lesser extent and in many high tide cycles, the water no longer reaches the top of the sand.

The borough council ought to be thinking of including the zig-zag groynes in a programme of replacement or comprehensive repair. They have been at the mercy of two tides every day for the last 35 years and the intermediate oak posts particularly are damaged and badly eroded.
