(b) Review process. Upon determining that all submittal requirements have been met, the agent shall coordinate a review process to determine conformity of the proposal with all applicable requirements of this chapter and other applicable ordinances, requirements, and regulations.

(1) The agent may transmit copies of the preliminary plan to those county departments and state and/or federal agencies deemed appropriate for their review and comment and shall establish a date for which written comments shall be returned to the agent.

(2) After receiving the comments of all reviewing departments or agencies, or within sixty (60) days of submission of the preliminary plan by a subdivider, whichever shall occur first, the agent shall consolidate all of the comments and provide a written response to the subdivider.  In the event of a resubmission of a preliminary plan which has been previously disapproved, the response shall be provided within forty-five (45) days.

Where review by one (1) or more state agencies, including, but not limited to, the health department and/or department of transportation, is necessary, the comments or approvals of such state agency or agencies shall be provided within thirty-five (35) days of their receipt by the agent.

(3) The agent's written response to the subdivider shall include notification of approval or disapproval or approval with conditions. Such notice shall state any actions, changes, conditions, or additional information that is required to secure final approval of the preliminary plan and, if disapproved, the reasons for such action with specific reference to an adopted ordinance, regulation or policy and identifying such modifications or corrections as will permit approval of the plan.

(4) Where the agent has required that revisions or other actions, changes, conditions, or additional information be incorporated into the preliminary plan prior to approval, the subdivider shall resubmit, without additional fee, thirteen (13) copies (12 folded, one rolled) of the revised plan together with the original or a copy of any marked plans returned to the subdivider by the agent. In addition, a narrative description shall be submitted regarding how each of the actions, changes, conditions, or additional information required has been addressed on the revised plan. The revised plan shall then be reviewed in the same manner and within the same time elements as was the original.

(c) Effect of approval.

(1) Approval of the preliminary plan shall not constitute a guarantee of approval of either the development plan or the final plat.

(2) Approval of the preliminary plan shall constitute authorization for the subdivider to proceed with the preparation of development plans in accordance with the provisions of this chapter and the layout and design depicted on the approved preliminary plan.

(d) Term of validity.

The subdivider shall have one (1) year from the date of official notification of approval of the preliminary plan within which to file a development plan meeting all of the submittal requirements established in article IV of this chapter for the subdivision or section thereof. Failure to do so shall make the preliminary plan approval null and void. The agent may, on written request of the subdivider received no fewer than ten (10) working days prior to expiration of validity and for good cause shown, grant one (1) six-month extension of preliminary plan approval.
