W. Va. Code § 39-1-16
In case a proposed subdivision of any lot or parcel of land is situate within the corporate limits of any municipality, or abutting thereon, it shall be the duty of the owner, or owners, or his or their agent, to submit a plat or plan of such subdivision to the council or commissioners of such municipality, showing the street and alley connections that such subdivision makes with such municipality, and furnishing full information for the purpose of determining whether the proposed subdivision will impede or prevent the further development and extension of such municipality where such subdivision is situate. Before any such subdivision is finally laid out, it shall have the approval of the council or commissioners of the municipality wherein the subdivision is situate, or upon which it abuts, and such approval and the date thereof shall be indicated on the plat or plan of such subdivision before the same is finally filed in the office of the clerk of the county court and the county assessor's office.
