@Morshawn - Thanks for your comments.
- I see the 'aliasing' you're referring to, that shouldn't be a big deal to fix, I had noticed it earlier and forgot about it. Thanks for pointing it out again.
- Only part of the town/city is even finished there is much more to add. The part by the coast is only the docks, warehouses, etc. Which you are correct, would be subject to destruction from bad storms, etc. I really have only barely begun to add the houses and other structures.
- The river does have a 'channel' I beleive it just "washed out" when I was playing around with the terrain effects.
