I've been working on a TDM that takes place in a flooded city. It has two teams: the Army and the Resistance. The Resistance gets a Jetski and a Lifeboat. The Army gets a Rowboat, and there is a Blocko Sedan near their base.
The middle street in the map is pretty bare of cover, which is realistic, and makes it easier to drive the vehicles. There is also many choke points and good vantage points. The water slows you down a bit, so you should stay on the rooftops and inside of houses.
Here are some pictures.

The Resistance base is to the right with the bridge on it.

Most of the area, with the Resistance base in the background.

Another angle from right above the Police Department, which is where the Army's base is.

One of the rooftops, with an ammo pickup.

Another view from the Resistance base.

Fancy DOF shot from the bridge.

A look at the billboard, and the Army base.

I'm not sure when this will be hosted, or who will host it.
Feel free to rate and give constructive criticism.
I fixed the water due to popular demand.
