Construction of the Winter Berm at the City Beach is now underway and is expected to be completed by Dec. 6. The sand dune is built annually between Linden and Ash avenues to protect public and private properties from winter storms and high surf, especially during the king high tides of December, January and February. For safety reasons, the area where the bulldozer is working is closed to the public. Members of the public are also reminded to be cautious when at the beach during high surf conditions, when large waves can suddenly sweep over previously dry areas. In a normal winter, the berm will be removed in early March, but if the winter has been severe and the beach is badly eroded, the berm may stay up later in the spring season.
