Piers are a popular focus for boating and waterfront recreation. What pier owners need to know is that they can continue to place their existing piers on the water, the same as they’ve been doing for years. Most existing piers and wharves are grandfathered. All existing piers and wharves that were first placed in the water before April 17, 2012 are exempt from needing state approval and can be placed in lakes and rivers the same as they always have with few limitations.
