Article 6 — Lake County Zoning Code

SEC. 21-6. REGULATIONS FOR THE TIMBERLAND PRESERVE ZONE OR “TPZ” DISTRICT. ¶

6.1 Purpose: To provide for timberland preserve zoning and the conservation and protection of land capable of producing timber and forest products. The uses specified in this Section have been determined to be compatible uses consistent with the Timberland Productivity Act of 1982. The following regulations shall apply in all “TPZ” districts.
6.2 Applicability : Parcels proposed for Timberland Preserve Zone shall comply with the following criteria:
- (a) The land area concerned shall be in the ownership of one person, as defined in Section 38106 of the Revenue and Taxation Code and shall be comprised of single or contiguous parcels totaling eighty (80) acres, or forty (40) acres for Class I or II timberland soils.
- (b) The land shall be a site quality Class V or higher under Section 434 of the Revenue and Taxation Code.

(a) Applicants shall submit to the Planning Department a legible map drawn to scale defining the parcel(s) to be included. Said map shall be accompanied by an accurate legal description of the subject parcel(s).
- (b) Applicants shall submit to the Planning Department a plan for forest management either prepared by or approved as to content by a registered professional forester. The plan shall provide for the eventual harvest of timber within a reasonable period of time, as determined by the preparer of the plan.
- (c) The parcel(s) 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 State Board of Forestry for the district in which the parcel(s) is located, or the owner must sign an agreement with the Board of Supervisors to meet these stocking standards and forest practice rules by the fifth anniversary of the signing of the agreement. If the parcel is subsequently zoned as “TPZ”, failure to meet the stocking standards and forest practice rules within this time period provides the Board with grounds for rezoning of the parcel pursuant to Government Code Section 51121. (Ord. 1749, 7/7/1988)
- (d) The parcel(s) shall be timberland, as defined in Subdivision (f) of Government Code Section 51104.
