Ind. Code § 8-10-5-3
Any county, which seeks to create a port authority shall, prior to such creation of a port authority, and prior to the exercising of the hereinafter described rights, compensate in full the municipal corporations included in the territory of such county, in an amount of money equal to the waterfront investment of such municipal corporations in the territory or adjoining lands including but not limited to appropriations, expenditures, charges for materials used or labor performed by public officials or employees of said municipal corporation in the placing, construction, development, or improvement of land fills; waterfront shoreways or highways; bulkheads; connecting ways; tracts, breakwaters; soil erosion projects; harbor improvements; public beaches; boat harbor facilities; drainage systems; docks; bridges; wharves; piers; places; ways; buildings and appurtenances; sewers; public utility facilities for power, light, heat or water; dredging or channel improvement projects; communications systems; and lakefront improvements. Such municipal corporations may decline to demand compensation for any of the foregoing components of their waterfront investment and thereby retain their possession, custody, control, and property interest in the component for which no compensation is demanded.
Such compensation paid to the municipal corporation may not be derived or take origin directly or indirectly from levies, taxes, assessments, fees, or charges of any kind or nature which were imposed or will be imposed upon the citizens, electors or taxpayers of the municipal corporation which receives such compensation.
