(c) (1) Subdivision (a) does not apply to the approval of a tentative map, or a parcel map for which a tentative map was not required, that would subdivide land identified in the open space element of the general plan for the managed production of resources, including, but not limited to, forest land, rangeland, agricultural land, and areas of economic importance for the production of food or fiber, if the subdivision is consistent with the open space purpose and if, for the subdivision of land that would result in parcels that are 40 acres or smaller in size, those parcels are subject to a binding and recorded restriction prohibiting the development of a habitable, industrial, or commercial building or structure. All other structures shall comply with defensible space requirements described in Section 51182 of this code or Sections 4290 and 4291 of the Public Resources Code.
