S.C. Code Ann. § 6-29-520: Advisory committees; notice of meetings; recommendations by resolution; transmittal of recommended plan.

(A) In the preparation or periodic updating of any or all planning elements for the jurisdiction, the planning commission may use advisory committees with membership from both the planning commission or other public involvement mechanisms and other resource people not members of the planning commission. If the local government maintains a list of groups that have registered an interest in being informed of proceedings related to planning, notice of meetings must be mailed to these groups.

(B) Recommendation of the plan or any element, amendment, extension, or addition must be by resolution of the planning commission, carried by the affirmative votes of at least a majority of the entire membership. The resolution must refer expressly to maps and other descriptive matter intended by the planning commission to form the whole or element of the recommended plan and the action taken must be recorded in its official minutes of the planning commission. A copy of the recommended plan or element of it must be transmitted to the appropriate governing authorities and to all other legislative and administrative agencies affected by the plan.

(C) In satisfying the preparation and periodic updating of the required planning elements, the planning commission shall review and consider, and may recommend by reference, plans prepared by other agencies which the planning commission considers to meet the requirements of this article.
