Heyho, a few questions that might help me with my new Genesis fort:
1. A well is built above open space and will need at least (5/7 or was it 4?) water in any tile below it (the further below the longer getting water will take). The best way to get water depends on your embark. If you have a river or brook you can get the water by digging an underground tunnel to it (make a lever operated door or floodgate for safety with a constructed fortification in front of it). If you have no water outside but have some in a cavern a similar method is used, you can carve the fortification into the stone to let the water in and keep swimming monsters out (they might get pushed through the fortification by moving water, so again make a floodgate/door to switch off the flow once your cistern is full.
It's preferable to make the area below the below the well 2 z-levels tall so the upper level contains water without mud (dwarfs don't like muddy water, it also increases the chance of infections when cleaning patients). Use a pressure regulator so your well doesn't spill over.

3. Random x-y direction (i think 5 tiles max). I think you might want to replace this with a retracting bridge as the current design has probably a 50% chance of throwing attackers back on the path or into your fort.
