Either party may propose an amendment to, or cancellation in whole or in part, of an executed development agreement. If proposed by the developer, the procedure for proposing and adoption of an amendment to or cancellation in whole or in part of the development agreement shall be the same as the procedure for entering into an agreement in the first instance. However, where the City initiates the proposed amendment to or cancellation of the development agreement, it shall first give at least thirty (30) days notice to the property owner of its intention to initiate such proceedings in advance of the giving of public notice of hearing.
