At the public hearing, the board of commissioners shall hear all interested persons who appear with respect to any matter covered by the preliminary assessment resolution. At or after the hearing, the board may adopt a final assessment resolution directing that the project or portions thereof be undertaken. The final assessment resolution shall describe the project in general terms (which may be by reference to projects described in the preliminary resolution) and shall set forth the following:
The percentage of cost to be assessed may not be different from the percentage proposed in the preliminary assessment resolution, nor may the project authorized be greater in scope than the project described in that resolution. If the board decides that a different percentage of the cost should be assessed than that proposed in the preliminary assessment resolution, or that the project should be greater in scope than that described in that resolution, it shall adopt and advertise a new preliminary assessment resolution as provided in this Article.
