Rhode Island General Laws Title 45. Towns and Cities § 45-22.1-6. Interstate participation

Wherever a joint municipal planning commission has been or is being established to serve the Rhode Island portion of an area, which for planning purposes constitutes a logical planning area and extends beyond the boundaries of the state, the commission may admit to membership counties or municipalities that are part of the same area but located in other states. Municipalities may participate through membership and financial support in joint municipal planning commissions that have been or are being established in other states when the municipalities are part of the same region served by the out-of-state joint municipal planning commission.
