When all of the owners of property to be benefited and assessed for a local improvement have signed a petition directed and presented to the council requesting the local improvement, the council may initiate and construct the local improvement without publishing or mailing notice to the owners of the affected property and without holding a public hearing regarding the proposed local improvement. Petitioners for a local improvement shall be liable for all costs of the improvements including costs incurred prior to abandonment pursuant to BC 3.02.215, except as otherwise provided by council. Petitioners’ liability shall be both personal and secured by a lien on the property. [BC 3.02.035, amended by Ordinance No. 3466, 9/17/85]
