The board may hold a hearing to determine if any property located outside of a division will benefit from any construction, improvement, or maintenance project proposed to be undertaken by the division.
Notice of the hearing shall be published in accordance with Section 1196. Notice shall also be mailed by the board, at least 10 days prior to the hearing, to all landowners whose property located outside of the division may benefit from the proposed project. The failure to mail any notice, or the failure of any person to receive such notice, shall not affect the validity of any action taken by the board under this section.
If, after hearing all of the evidence introduced at the hearing, the board finds and determines that property located outside of the division will benefit from the project proposed to be undertaken by the division, the board may order the boundaries of the division to be modified so as to include such property. Thereafter, the boundaries as modified shall be the legal boundaries of the division.
