I understand what you mean, but I know the low spots and high spots on my property and it is not reflected by the flood zone, I would say the topo line has been smooth out or generalized but is more accurate then the flood line... as a example see where the bleu circle is that is a low spot on my property which is why I put in my propose flood zone within the sky blue but it is not in the flood zone in red and you see the elevation line in pink above it.I realize you are in Canada but in the US my understanding is the flood elevations are fairly accurate the way they are calculated. What is not accurate is the elevations of peoples property. Say the base flood elevation is 290. That number is probably in the ballpark. They show a part of your property in the flood at elevation 287. Maybe that part of the property is really 295. That’s kind of what it sounds like is going on with your property.
this is the map they used for the flood zone limits, I am still trying to figures out where its came from and who did it, but notice on it there is no topographic lines on it, so it looks like a child draw boundaries around streams.
