Impact of Gravel Extraction PAGE Campaign

Gravel extraction in this area would have an adverse effect on our local economy. People come to this area because it is an unspoilt section of the River Thames. Pubs, shops, hotels and river facilities would all suffer as it would be extremely difficult to hide gravel extraction workings in such an open landscape.get price
