SHEBOYGAN, WI (WHBL) - The city of Sheboygan could be faced with a 2.5-million dollar project to prevent future wave damage in the Harbor Centre Marina. Chris Matheson of Siegl Gallagher, which manages the marina, told aldermen during Wednesday night’s Committee of the Whole meeting that wave action causes an average of $45,000 in damage to the marina docks each year, but last winter the damage came to $350,000. He said that is the most damage suffered by any marina in the country. Matheson said a 400 lineal foot rip-rap wall made up of 47,000 tons of rock built at the marina entrance would prevent it. Aldermen took no action but heard from City Planning Director Chad Pelishek, who said there may be grant money available to help with the project. Pelishek said the next step is for the city to take Matheson's proposal to various state or federal agencies to determine how receptive they are and what level of grants are available, then bring that information back to the council for action.
