In addition to any other requirements, the chief building official may require the submission of such materials as are necessary to insure compliance with the provisions of this chapter, which may include, but shall not be limited to: plans in duplicate drawn to scale showing the nature, location, dimensions and elevations of the area in question; existing or proposed structures, fill, storage of materials, drainage facilities; and the location of the foregoing.
