Madison committee reviews a proposed framework that would exclude hyperscale data centers
What changed
Madison staff presented a proposed data-center zoning framework to the Sustainable Madison Committee on October 19. The framework would define size tiers, restrict large facilities to industrial areas, and not allow hyperscale facilities over 100,000 square feet; it is staff guidance under review, not enacted zoning.
