At the public hearing, the council shall hear all interested persons who appear with respect to any matter covered by the preliminary resolution. After the public hearing, the council may adopt a resolution directing that the project or portions thereof be undertaken. The 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, and the projects authorized may not be greater in scope than the projects described in the preliminary resolution. If the council decides that a different percentage of the cost should be assessed than that proposed in the preliminary resolution, or that any project should be enlarged, it shall adopt and advertise a new preliminary resolution as herein provided.
