I don't like doing the `parseInt` twice.  We can move that out of the switch to the top.  Also, a `NaN` value is falsey so we can probably simplify this statement as well to just

```coffeescript
# above the switch statement
unfloodProtectionDelay: (unflood) ->
  unfloodDelay = parseInt(unflood) or 1000
  # .. snip switch ..
    when true then unfloodDelay
```

And since it's now just a switch on a true and false value it should probably be just an if statement.
