The Public Domain Zone (PDZ) as designated on the Mariposa County Zoning Map, is applied to lands under public ownership, primarily by the U.S. Forest Service or Bureau of Land Management outside the boundaries of the federal preserve known as Yosemite National Park.

1. Development standards for the PDZ. Due to the federal regulations governing public lands and to the limited use authority over such lands by the county of Mariposa, instead of using permitted, conditional and prohibited uses as in other zones, development standards for the PDZ shall be set forth as follows:
   1. Uses:
      1. Primary uses: The primary uses of lands designated as PDZs shall be: sustained yield timber management, harvesting, and associated activities; grazing and other agricultural uses; mining and mineral processing; non-commercial recreation; hydro-electric generation, and other similar uses. Wilderness and similar uses proposed for these lands shall be reviewed in accordance with the above primary uses and federal policy, or contemplated policy, and evaluated accordingly. In all instances motorcycle raceways, cross-country course, or similar vehicular uses are to be restricted within PDZs where such activities create a nuisance to adjacent or abutting private landholdings, or interfere with the above listed primary uses.
      2. Ownership transfers: When, in the event that a federal or other public agency transfers land to a private individual or non-public entity, the above-described use policies shall govern until such time as the site or land thus transferred is reclassified to another land use category in accordance with state law and county procedures. Until such reclassification is approved by the county, development proposals, subdivision applications, or use proposals not described above shall be considered inconsistent with this land use category and cannot be approved.
