OPINION
Wе granted this appeal to determine whether Tenn.Code Ann. § 13-7-105(a) mandates submission of a newly proposed zoning classification amendment to the regional planning commission following the commission’s rejection of a similar but different proposed classification. The Court of Appeals held that the statute does not require futile resubmissions of revised proposals. We, however, find that the proposal in question was not merely a revised priоr proposal but was a new and previously unsubmitted proposal. The statute clearly mandates submission of new proposals to the regional рlan *282 ning commission. We reverse the Appellate Court and hold that the new zoning proposal should have been submitted to the regional planning cоmmission.
BACKGROUND
The appellee, Thomas N. Schriver, filed a rezoning application with the Knoxville-Knox County Metropolitan Planning Commission (“MPC”). His applicatiоn sought to amend a tract of land’s zoning from Agriculture (“A”) to Shopping Center (“SC”) 1 . The MPC unanimously denied Sehriver’s requested change. He then appealed the MPC’s decision to the County Commission.
During the hearing before the County Commission, the appellee presented a zoning proposal that differed from the proposal he originally submitted to. the MPC. He requested the commission to rezone the property to Planned Commercial (“PC”) 2 as opposеd to SC. The County Commission approved the revised amendment request and rezoned the property as PC.
The appellants, Westland West Community Association, et al., appealed the commission’s zoning decision to the Knox County Chancery Court. They alleged that the Commission’s decision was void. They argued that Tenn.Code Ann. § 13-7-105(a) 3 mandated that the appelleе submit his new proposal to the MPC prior to seeking review before the County Commission. The chancery court agreed and held that when the appellee changed his request from SC to PC, he was required to by statute to resubmit the zoning request to the MPC.
The Court of Appeals reversed the chancery court’s decision. They found that resubmission of the more onerous proposed amendment to MPC would have been futile due to the MPC’s previous determination thаt “any commercial zone would be contrary to the ... Sector plan.” Pursuant to

STATUTORY CONSTRUCTION
The appellants argue that the Court of Appeals erred in focusing its analysis solely on whether the board’s decision would have been the same upon resubmission. They maintain that the рroper inquiry should focus on the gravity of the revised proposal’s changes. Provided the revisions are substantial, Tenn.Code Ann. § 13-7-105(a) mandates resubmission. We аgree in part.
A county legislative body is vested the statutory power to amend zoning ordinances. Tenn.Code Ann § 13-7-105(a). A proposed zoning amendment, howеver, shall neither be granted nor become effective unless the proposed amendment is first submitted to the regional planning commission. Id. The regional commission can then either approve, disapprove, or make suggestions. Id. If the regional commission rejects the proposed amendment, the amendment may then be submitted to the county legislative body for approval. Id.

Our analysis is guided by the principles of statutory interpretation. Legislative intent shall be derived from a statute’s face when a statute’s language is unambiguous.
Hamblen County Educ. Ass’n v. Hamblen County Bd. of Educ.,
We find the statute’s language clear. A proposed amendment to a zoning scheme must first be submitted to the regional planning commission. If a proposed zoning amendment is not first presented to the regional planning commission, the county commission is devoid of jurisdiction to act upon the proposal.
Once a proposed amendment has been submitted to the regional planning commission, the proposal may be revised. Whether the revised proposal must then be resubmitted to the regional planning commission is contingent upon: (1) the gravity of thе revision(s), and (2) whether the board’s recommendations would have been altered by the revision(s).
Wilgus v. City of Murfreesboro,
In the present case, we are not confronted with a mere revision to a previously proposed zoning amendment. Accordingly, we do not revert to the test for determining whether a revision was substantial. We are confronted with an entirely new zoning classification proposal (i.e., a new zoning amendment proposal) which had never been bеfore the regional planning commission. We find a clear distinction between a newly proposed classification and a previously submitted clаssification that has undergone mere revisions. Tennessee Code Annotated § 13-7-105 mandates submission of the new classification without further inquiry.
Accordingly, we hold thаt the proposed zoning change to planned commercial in the present case must have been presented to the regional plаnning commission before the county commission had jurisdiction to act on the proposal. The county commission’s review and approval was, therefore, both null and void. Costs shall be taxed to the Knox County Board of Commissioners for which execution may issue if necessary.
Notes
. SC is limited to retail uses. SC limits building height to a maximum of three stories and is intended for retail developments that generally attract consumers from the surrounding residential areas.
. PC permits extensivе commercial services and light distribution centers. Buildings may exceed four stories in height in land zoned as PC. PC is intended to draw customers from both outside and inside the immediate residential area. This attraction of a larger market may increase consumer traffic to the area. The presence of commercial trucking may also be more prevalent in land zoned as PC as opposed to SC.
.Tennessee Code Annotated § 13-7-105 provides, in pertinеnt part, as follows:
(a) The county legislative body may from time to time amend the number, shape, boundary, area or any other provision of any zoning ordinance; but such amendment shall not be made or become effective unless that same be first submitted for approval, disapproval or suggestiоns to the regional planning commission of the region in which the territory covered by the ordinance is located, and, if such regional planning commissiоn disapproves within thirty (30) days after such admission, such ■ amendment shall require the favorable vote of a majorily of the entire membership of the county legislative body.
