You may wish to consider sand in your wet soil if it has a high clay
content, which is likely. The sand will allow quicker drainage.
Compost is always rightly prescribed for just about any soil problem and it
will serve you well. Evergreen wood chips are super as a mulch but you may
be in a location with lots of slugs or snails. These aren't the beneficial
garden critters you were thinking of, I suspect. They will like that mulch
to hang out in. Your young tender bean plants and such will make a
tasty nightly salad for these critters.
Removing a few inches of soil from permanent garden paths and placing it
on your beds may give you enough elevation to keep the plants from being
submerged during a rain. Consider making wider paths and narrower beds to
get the soil level where you need it. Might save some work especially if
you decide to haul in some sand and compost.
I agree entirely with Don on the subject of the fabric and gravel. They are

I have started working with a teachers at a local middle school who
laying plans for a raised bed garden. The ground on which the beds
placed is typically soggy during the rainy season and there's some
that the soil in the beds will not drain properly. Someone has
that a layer of fabric and then a layer of gravel be placed in the
the beds before the soil.
My concern is that roots would be too restricted in a 8 to 10 inch layer
soil as the roots will be unable to reach threw to the ground. Also,
would be concerned that worms and other beneficial critters might not
able to reach the soil in the beds with this barrier.
Any comments or suggestions on this?
