I'm not working with much space But I dug down far as I could - 3 feet sounds not so deep but it is for clay I built up about a foot of an interwoven core with tons of sticks - puzzled em together to fit as much as possible Filled in the soil Later I dug down 2 feet to the old core & added another tight bundle of stick jenga Got my little scythe & got 4 biiiiiig bundles of dry tall grass - u can pack as much as u can carry into a very small space. & then I just recently raked 6 inches of soil back to build a third core layer . Highly reccomend going crazy with cores. U can set aside a bed just for building soil. Stretching & balancing store bought soil out by a lot. Pop some potatoes or Jerusalem artichokes or ginger or garlic in there in the meantime. Very fun to know thats all getting eaten up by worms. Only way i know of to really improve drainage - also depending on ur area it would either increase or decrease drainage to your needs depending on what ur burying
