No persons, firm or corporation shall strip, excavate or otherwise remove topsoil for sale or for use other than on the premises from which the same shall be taken, except in connection with the construction or alteration of a building or paved parking area on such premises and excavation or grading incidental thereof; provide, however, that the Town Board may, by special permit, grant an application for such stripping where it finds that such will not be detrimental to the adjoining land and building development.
