I'm with Tanada on this one. Not only are the North American Great Lakes the largest bodies of fresh water on the planet, but their altitude makes the coming 10m or so of sea level increase a non-issue, as water levels are managed quite handily by the St. Lawrence Seaway series of locks. These locks are passive, requiring only the opening and closing of valves to operate. 10-30 meters of sea level rise will only impact the lowermost Lake Ontario locks, the other lake coastlines are likely stable until the glaciers come again.
The Western shore of Lake Michigan which is my target area has tides that are only 2-3 inches, and storms that seldom surge more than two feet. For the most part, the building codes require a setback beyond the 100-year storm line. There are some beautiful homes there:

Like most of rural America, the area is underpopulated and services are somewhat sparse. However there are no known oil or gas shales in the area, either, nobody is likely to begin drilling around you. The water table around the lake is so high that people don't bother to drill wells, they just drive a perforated "well point" down a few feet and they have clean water.
Tanada has already mentioned the moderating impact on the climate that is felt when one lives next to so much fresh water, the Winter temps are higher and the Summer temps lower than the inland areas. Most homes are heated by propane and have a 500-gallon or larger tank in the yard. Hot water baseboard and forced air are popular options, backed by wood heat. These homes are easily adapted to all-electric after super-insulation, which is absolutely required as the area is heating Zone 6, the Winters are quite harsh. If one is going to live there, one needs a snow machine for travel and a scheme for plowing snow out as far as the public paved road. (At least until the AGW kicks in, if one is a believer in such.)
