Without even studying yours... here's my ideas.. and those I "wish I had done"
-- put the dust/chip producers together on a simple central 1.5hp collector with 6" s&d pipe -- refitted the TS, jointer, and BS with 6" dc ports. Another "branch" of the line could accomodate miter station / planer / other. I grouped them all close together and in aligment so as to simplify the dust pipe plumbing.
-- outlets along the wall at about 4-foot high (already there -- had to cut out one single gang box and make it a double (4 outlets) -- would have liked to have them about every 4' apart
-- dedicated 220 outlet for DC
-- 3 220 outlets on same circuilt for TS, Jointer, and TBD
-- dedicated outlets circuit
-- dedicated lights circuit
-- outlets in ceiling to which I just plug standard 4' shop lights -- works very well -- just drive a screw threw the fixture into a ceiling
2x
-- hate the cord web on my ceiling from the previous solution -- should have added 2 more outlets and planned this out better
-- situated the TS near the garage door -- when cutting 4' material, no problems; when cutting >4' just open the garage door (also this fits into the DC design well)
-- overhead cabinets along 1 wall - attached to wall with french cleats -- 3 cabinets
-- open legged workbench under those cabinets -- plan was to put rolling drawer carts under the open bench -- might scrap that idea and just build-out the drawer cabinets, sit on leveled base, and put workbench atop
-- priming all the walls, then painting (do this BEFORE you add a bunch of stuff!!!!!!!)
-- planning 16' of shelving along 1 wall (ww stuff but also other shop items -- oil, battery charger, etc.
-- thinking about a low-cost way to cover-up that shelving. thinking maybe a clear shower curtain -- see-through, but blocks-out dust build- up
-- sheet goods on roller cart plan-in-the-works
