Here are a few other considerations before you build, even if you're convinced you're in compliance with the law:

• Are you damaging the environment? Bodies of water are often delicate ecosystems, and building a dock can be destructive and disruptive to the wildlife.

• Are you blocking access? Lots of people like to use a lake, so you need to make sure your dock doesn't block public access to the water.

• Can you enclose the dock? Just because you can build a dock doesn't mean you can build any dock you want. Some areas don't allow enclosed docks, for example.

• Do you need to follow any specific rules or guidelines? Check with the National Oceanic and Atmospheric Association (NOAA) Office for Coastal Management for any guidelines you’ll need to follow, including size and type restrictions.

Repair costs range from $500 to $5,000, depending on material type, structural damage, and labor. Extensive piling or decking replacements increase the price.

Bulging walls, cracks in the seawall's top or side, and the appearance of a seawall "pulling away" are all signs that you need repairs or reconstruction. The area around the seawall can also provide clues. For instance, you may notice water bubbling over in areas of your yard if your seawall has holes or cracks. The soil around the seawall may also appear to be sloping or sinking.
