B.
When granting approval to a preliminary plan, the Board shall state the conditions of such approval, if any, with respect to:
(1)
The specific changes that it will require in the final plan;
(2)
The character and extent of the required improvements for which waivers may have been requested and that, in the Board's opinion, may be waived without jeopardy to the public health, safety, and general welfare; and
(3)
The amount and type of all performance guarantees that it will require as prerequisite to the approval of the final plan.
C.
Approval of a preliminary plan shall not constitute approval of the final plan or intent to approve the final plan; rather, it shall be deemed an expression of approval of the design of the preliminary plan as a guide to the preparation of the final plan. The final plan shall be submitted for approval of the Board upon fulfillment of the requirements of this chapter and the conditions of preliminary approval, if any. Prior to the approval of the final plan, as a result of the further study of a subdivision or as a result of additional information received, the Board may require additional changes or other conditions that it deems necessary. The final plan shall satisfy all of the approval criteria for subdivision approval set forth in this chapter and in 30-A M.R.S.A. § 4404.
