(a) The landowner may petition the board or council for cancellation of any contract as to all or any part of the subject land. The board or council may grant tentative approval for cancellation of a contract only if it makes one of the following findings:

1. (1) That the cancellation is consistent with the purposes of this chapter.
2. (2) That cancellation is in the public interest.

(b) For purposes of paragraph (1) of subdivision (a) cancellation of a contract shall be consistent with the purposes of this chapter only if the board or council makes all of the following findings:

1. (1) That the cancellation is for land on which a notice of nonrenewal has been served pursuant to Section 51245.
2. (2) That cancellation is not likely to result in the removal of adjacent lands from agricultural use.
3. (3) That cancellation is for an alternative use which is consistent with the applicable provisions of the city or county general plan.
4. (4) That cancellation will not result in discontiguous patterns of urban development.

5. (5) That there is no proximate noncontracted land which is both available and suitable for the use to which it is proposed the contracted land be put, or, that development of the contracted land would provide more contiguous patterns of urban development than development of proximate noncontracted land.

   As used in this subdivision “proximate, noncontracted land” means land not restricted by contract pursuant to this chapter, which is sufficiently close to land which is so restricted that it can serve as a practical alternative for the use which is proposed for the restricted land.

   As used in this subdivision “suitable” for the proposed use means that the salient features of the proposed use can be served by land not restricted by contract pursuant to this chapter. Such nonrestricted land may be a single parcel or may be a combination of contiguous or discontiguous parcels.

(c) For purposes of paragraph (2) of subdivision (a) cancellation of a contract shall be in the public interest only if the council or board makes the following findings: (1) that other public concerns substantially outweigh the objectives of this chapter; and (2) that there is no proximate noncontracted land which is both available and suitable for the use to which it is proposed the contracted land be put, or that development of the contracted land would provide more contiguous patterns of urban development than development of proximate noncontracted land.
