We use woodchips here in Philly for the same reason. Many gardeners put down carpet scraps to keep weeds from coming up, then cover them with chips. Over time (usually a few months) the chips break down, so spring and fall we shovel them up into the beds to supplement the soil, then spread more chips.
Even if powers-that-be insist on plowing/tilling, chips spread out in the fall will have broken down enough and shouldn't be a problem to spring plowing. Just put cardboard or newspaper down as a base instead of the carpeting. Sally McCabe > Since wood chips are delivered free to our garden, we use them.
