A DRI is a development which, because of its character, magnitude, or location would have a substantial effect upon the health, safety, or welfare of citizens of more than one county. The DRI process is governed by Chapter 380.06, Florida Statutes ("F.S.") and Rules 9J-2.001 through
9J-2.0256, Florida Administrative Code ("F.A.C.").

There are 14 types of development which may be DRIs if they exceed certain numerical thresholds. The types of development include airports, hospitals,mines, hotels, marinas, industrial, office and retail uses, residential projects and multi-use developments. The types and numerical thresholds are identified in Section 380.0651, F.S., and Chapter 28-24, F.A.C.

The Florida Department of Community Affairs web site will provide a detailed discussion of the DRI process and provides downloadable DRI application forms. Legislation and rules applicable to the DRI process may also be found at this web site.

The Tampa Bay Regional Planning Council is also involved in the DRI process.
