Great info. Thanks for capsulizing it.

In this neck of the woods/prairies we're getting far too many floodings from weather phenomena, such that building codes are now gearing up for so-called 1-in-1000-year rains, meaning that location (house-siting) must conform to new criteria relating to proximity to water bodies, slope of site, etc. Insurance on non-conforming properties (including those already extant) becomes problematic — not to put too fine a point on it.
