Maryland County Commissioners Section 189

      (a)      All benefited lands within the watershed association shall be assessed for the cost and expense of carrying out the proposed works of improvement; and the said board of watershed viewers shall adjudge thereof, and shall assess against such lands respectively a sum proportional to the benefits accruing thereto. In no case shall the assessment against any tract of land exceed the benefits that will accrue to such tract from the proposed improvement. The sums so assessed shall be sufficient, less such amounts in funds or services as may be received from the county commissioners or from any other source, to cover the costs of such works of improvement, the payment of damages awarded (if any), the payment of compensations for adopted improvements previously constructed (if any), the expenses of the board of watershed viewers, and the costs of establishing the watershed association.

      (b)      Notwithstanding any other laws to the contrary, the county commissioners are authorized to contribute in funds, services, equipment, or materials all or any part of the cost of any improvements authorized under this subtitle from general funds of the county, or to allocate for use in paying for all or any part of the costs of any such improvement any other funds which may become available for such improvements.
