California Code, Government Code - GOV § 56667

If the report filed pursuant to Section 56665 indicates that more than 50 percent of the land proposed for incorporation is owned by or dedicated to the use of a city or county and that the proposed incorporation would result in a revenue loss to that city or county, and at the hearing held pursuant to Section 56666 the board of supervisors of the county or city council of the city presents a resolution objecting to the incorporation, no further proceedings shall be conducted by the commission and no new proposal involving incorporation of substantially the same territory shall be initiated for one year.

In the absence of a resolution of objection from a city or county, the commission may approve the proposal only if it imposes as a condition thereto that the newly incorporated city may not adopt any regulation or policy which would have a negative fiscal impact on any contract existing at the time of the incorporation which is related to the publicly owned land.

This section shall not preclude the completion of proceedings to incorporate territory which is the subject of incorporation proceedings filed with the executive officer of the commission prior to February 15, 1986.
