Two primary things to consider: Fetch and surge.
If your dock has open exposure to a large body of water (say 1/4mi or more in any direction), the seas will build and tear things up. If in a canal or protected basin, should not be a problem.
Look at pilings, docks and tie points. Now imagine water ten feet higher. How will things be then. Best case is floaters with very tall piles. Every thing goes way up, then comes way down. No muss, no fuss. Fixed docks, piling ties, bulkhead ties can be a challenge. Floaters on 8' piles, no bueno.
Haulouts: Look at elevation. Six feet above SL, no bueno (Sandy). 15' above, good. Also look at drainage around storage area. In one local yard, the rain wash came down the hill and washed out around boat stands and few boats fell over. The boats on the higher side of the lane were fine. Some had the forethought to insist on that side as they saw the gullies on the other. Paved storage area should not be an issue, but up here in redneck land that is super rare. Often just dirt, expensive ones have some gravel.
