The Timber Exclusive Zone (TEZ)is a timber preserve zone for the growing and harvesting of timber for those uses which are an integral part of a timber management operation. Land use under a TEZ shall be restricted for a minimum of ten (10) years to growing and harvesting timber, and to compatible uses approved by the county.

1. Development standards for the TEZ. Development standards for the TEZ shall be as follows:
   1. Uses.
      1. Permitted uses: Growing and harvesting of timber and forest products; uses and facilities appurtenant to timber growing and harvesting, including but not limited to roads, log landings, and log storage areas. Residential, grazing, wildlife preserves; management for watershed, fish and wildlife habitat; hunting, fishing, hiking and camping; forest fire lookout stations; fire stations provided they are located on timberland converted to non-timber use in accordance with section 1104.1 of Title 14, California Code of Regulations; exploration or prospecting for minerals; portable saw mills and portable planing mills; gas, electric, water or communication transmission facilities; wholesale nurseries and similar horticultural enterprises; and those applicable uses listed under Chapter 17.108.
      2. Conditional uses: The following uses shall be permitted only with a conditional use permit: Timber products processing plants, including but not limited to such permanent facilities as saw mills, lumber and plywood mills, planing mills, provided that the plants are secondary or incidental to timber growing and harvesting operation on the same parcel; logging camps or labor camps appurtenant to timber harvesting or planting operation for the duration of one year; additional dwellings when necessary for the timber management operation; membership or public parks and camps which require no permanent facilities; guest ranches, hunting clubs, public stables and riding trails in conjunction with a bona fide timber management operation; mining and quarrying for the removal of minerals and such appurtenances as required; surface mining operations shall include, but are not limited to: in-place distillation, retorting or leaching; production and disposal of mining waste.
      3. Prohibited uses: All uses listed in section 17.108.200 of this title and other uses not listed above are prohibited, except similar uses in compliance with section 17.108.120 and 17.108.030 of this title.
   2. Property development standards: In addition to Title 5, Division 1, Chapter 6.7 of the California Government Code, the following property development standards shall apply to all land and structures in the TEZ: Each parcel prior to acceptance into the TEZ, shall have a minimum of ten thousand (10,000) board feet per acre, or meet the minimum timber stocking standards of the state within five (5) years.
      
      A timber management plan shall be presented to and approved by the Mariposa County planning commission. This plan shall be prepared by a registered professional forester. The parcel shall currently meet the timber stocking standards as set forth in section 4561 of the Public Resources Code and the forest practice rules adopted by the California State Board of Forestry for the zone in which the parcel is located; or, the owner must sign an agreement with the board to meet such stocking standards and forest practice rules by the fifth (5th) anniversary of the signing of such agreement. If the parcel is subsequently zoned as timberland preserve under Subdivision (a) of section 4561 listed above, then failure to meet such stocking standards and forest practice rules within this time period provides the board with a ground for rezoning of the parcel pursuant to section 51121 of the Government Code.
      
      Other provisions of this title notwithstanding, all lands zoned in a TPZ in accordance with County Ordinances 464 and 557 are hereby zoned in accordance with the provisions of this chapter as a TEZ. All rules, policies and provisions of previous TEZs are deemed consistent with the provisions of this chapter and nothing contained herein shall be deemed to minimize, null, or otherwise set aside any permits, plans, or other benefits granted or otherwise obtained under the provisions of a previous TEZ.
      
      
   3. Minimum parcel or lot size: No parcel or real property shall be divided or split into two (2) or more parcels by voluntary transfer, court action or other conveyance where any one (1) of the parcels so created will be less than forty (40) acres or a legal quarter-quarter section.
   4. Density: Two (2) single family residences per forty (40) acres or a legal quarter-quarter section.
