What is a TDD?
A Transportation Development District (TDD) is a special taxing district whereby a petitioner of 100% of the landowners in an area request either the levy of special assessments or the imposition of a sales tax of up to 1% on goods and services sold within a given area. Upon creation of a TDD by a municipality, the revenue generated by TDD special assessments or sales tax under Kansas law may pay the costs of transportation infrastructure improvements in and around the new development.
