Kentucky Revised Statutes Title IX. Counties, Cities, and Other Local Units § 100.121.Joint planning units

(1) At any time, the legislative bodies of cities and the fiscal court of the county containing the cities may enter into an agreement to form a joint planning unit by combining planning operations in order that they may carry out a joint city-county planning program. Combinations may include any combination of cities with their county or parts thereof; provided, however, that no self-excluded city in such county may form an independent planning unit.

(2) When a planning unit includes a county and a city of the first class or consolidated local government created pursuant to KRS Chapter 67C, then all other cities within the county shall also be parts of the unit.
