The blue foam comes from http://www.craftfoam.co.uk. Its pricy (approx £55 for a box) but you get a lot of foam for that money. The 25mm thick stuff that I am using on this board comes in a box of 12 sheets, and each sheet is 600mm square (just over 2' square). Perfect for splitting with friends or a club.
To cut it I have been using the score and snap method to get the pieces to the correct approximate size and then a hot wire cutter to tidy up the edges.

Couple of people asked me about the size - its a 3' square, the main canal is 6" wide and the sub canals are 3". Fortunately I can fit a 3' board in the back of my car so don't need to make it in 2 pieces.
The terrain on top of the board will be moveable scatter terrain but will have predefined places so that when I set it up it will be the same every time, not sure if I will mark those places somehow - black shadow areas perhaps - but will definitely have pictures so I remember how it goes together as one of the things I learnt from the 4M tables is that if you have a lot of complexity then you will forget where it all goes :)
Right, think that about covers it. Glued some of the sections onto the board last night but have run out of No More Nails so will have to wait a few days before I can pick up some more. Oh well will just have to paint figures instead.
