As data centers proliferate across Florida, local governments are being asked to approve increasingly large facilities without a consistent framework for evaluating them. Below is a starting point for the kind of ordinance language that communities can adapt to their own circumstances.
Start with definitions and tiers
Not every data center is the same size or carries the same impact, so a workable ordinance should define the use by tiers, based on square footage or power draw, with proportionally more rigorous review for larger facilities. A small colocation facility serving local businesses should not trigger the same scrutiny as a hyperscale campus drawing hundreds of megawatts.
Build on existing mechanisms
Most counties already have conditional use or special exception processes that can be adapted for data centers rather than built from scratch. The ordinance should require applicants to submit utility capacity letters confirming the local electric provider can serve the proposed load, water use projections if cooling will rely on municipal supply, and a decommissioning plan addressing what happens to the structure and site at end of life.
Address key impacts
Noise from backup generators and cooling systems should be addressed with specific decibel limits measured at the property line, not just a general nuisance standard. Setbacks and buffering from residential zones should reflect the industrial character of these facilities even when their exteriors are designed to look unobtrusive. And because data centers employ relatively few people per square foot compared to other industrial uses, communities should be realistic about the economic development case being made and weigh it against the infrastructure burden being created.
The FDISA model ordinance
The Florida Data Infrastructure and Siting Alliance has circulated draft model language that several counties are now reviewing, which incorporates many of these elements. It is not a perfect template for every jurisdiction, but it offers a useful baseline that local governments can modify to fit their own land use patterns and utility relationships rather than starting from a blank page.
The takeaway
Communities do not need to choose between welcoming investment and protecting their infrastructure and quality of life. A clear, tiered ordinance with specific technical requirements lets local governments say yes to responsible projects while giving staff and elected officials the tools to say no, or to negotiate meaningful conditions, when a proposal does not fit.
