A local government may approve a site-specific vesting plan upon any terms and conditions that may reasonably be necessary to protect the public health, safety, and welfare. Conditional approval results in a vested right, although failure to abide by the terms and conditions of the approval will result in a forfeiture of vested rights. A local government shall not require a landowner to waive the landowner's vested rights as a condition of developmental approval. A site-specific vesting plan is deemed approved upon the effective date of the local government's decision approving the plan or another date determined by the governing board upon approval. An approved site-specific vesting plan and its conditions may be amended with the approval of the owner and the local government as follows: any substantial modification must be reviewed and approved in the same manner as the original approval; minor modifications may be approved by staff, if such are defined and authorized by local regulation.
