ARTICLE 2 - Chapter 17.18

SPECIAL PURPOSE ZONING DISTRICTS

Sections:

17.18.010 Purpose.

17.18.020 Public District or (P) District.

17.18.030 Timberland Production District. 17.18.040 Mineral Preserve (MPZ) District.

17.18.010 Purpose. This Chapter lists the types of special purpose zoning districts and establishes the respective regulations for permitted land uses, conditional uses, minimum parcel size, building intensity, and transfer of ownership.

A. Purposes of Special Purpose Zoning Districts.

Public District or (P) District. The purpose of the Public (P) District is to acknowledge the limited ability of the County to impose regulations on land under the jurisdiction of public agencies, including, but not limited to, federal, state and local governmental bodies and public utilities. This zoning is compatible with all General Plan land use designations.
Timberland Production District. The Timberland Production (TPZ) District is for the protection of timberland and in order to prevent encroachment upon it by incompatible uses of land, and for the general welfare of the County as a whole. This zone is intended to qualify its land pursuant to Z'bergWarren-Keene-Collier Forest Taxation Reform Act of 1976 or such other legislative statutes or constitutional authorization as may be developed for defining a timberland preserve.
Mineral Preserve (MPZ) District. The Mineral Preserve (MPZ) District is for the protection of lands best suited for mineral or aggregate extraction from the encroachment of incompatible uses and to preserve such land for resource production.
