Its a mod, that i found, what it does is it raises the water level of only portland (so far)
All the items are raised about 30 feet up in the game. so when you are wasted, you spawn on the awning of the hopstial instead of underneath it.
If you stand at the shore long enough, all the people that are walking along, under the water (cause the pedpath wasnt modded) will eventually drown. cars will drive out of the water, but car that drive in will float. cant remember if they explode or not
heres a rough map of what the new shoreline looks like
