Snohomish County is slated to have 35 retail pot shops, with 16 of them in unincorporated parts of the county. The planning department released proposed legal pot zoning regulations which will help those pot businesses figure out where to lease. The catch? Pot shops will be allowed in 0.58% of the county-controlled zoning. That's a total of 11.23 square miles of unincorporated Snohomish County where a cannabis retailer may locate.
