Sec. 17-17. - Subdivision.

(A) Definition. "Subdivision" is the division of land as defined by California Government Code Section 66424 (Subdivision Map Act).

(B) Exclusions. "Division of Land" does not include, nor shall this Chapter apply to:

(1) The financing or leasing of apartments, offices, stores, or similar space within an apartment building, industrial building, commercial building, mobile home park, or trailer park;

(2) Mineral, oil, or gas leases;

(3) Land dedicated for cemetery purposes under the Health and Safety Code of the State of California;

(4) The conveyance or transfer of any interest therein to the United States, to the State of California, to the County of Mendocino, or to any city, school district, special district, or public utility;

(5) A boundary line adjustment which has been approved by the Subdivision Committee and which meets the definition of such as expressly set forth in this Chapter;

(6) The conveyance, transfer, creation, or establishment of an easement for sewer, water, or gas pipelines and appurtenance, or electrical or telephone poles and lines and appurtenances, or drainage, or private road purposes except when such private road easements are created by a subdivider over lands he has previously divided and said easements did not appear on the tentative map thereof;

(7) A lot or parcel of land released from a deed of trust where the owner of record remains unchanged; for the purpose of this exception, the division of land shall be deemed to occur upon a sale of such parcel or parcels to others than the parties to the Deed of Trust;

(8) The transfer of land or any interest therein by a deed which expressly restricts the use of the land to the construction, maintenance, and operation of a public utility; and

(9) A boundary line agreement entered into for the purpose of, and having the sole legal effect of, clearly establishing the common boundary line or lines between two or more contiguous property owners, said boundary line, or lines, having heretofore been uncertain as to physical location.

(C) Condominiums. "Subdivision" includes a condominium project, as defined in Section 1350 of the Civil Code, and a community apartment project as defined in Section 11004 of the Business and Professions Code.

(D) Contiguity. Property shall be considered as contiguous units even if it is separated by roads, streets, utility easements, or railroad rights of way.

(e) Cumulation of Parcels. The following rules shall apply for computing the number of parcels being created at the time of a division of land:

(1) In addition to the parcel or parcels being created, there shall be counted as a parcel every parcel contiguous to that being created, or contiguous to a parcel created subsequent to April 27, 1971, which has at any time subsequent to the aforesaid date been sold, leased, financed, given, conveyed, transferred, owned, or retained by the owner or subdivider.

(2) For the sole and limited purpose of determining whether a division of land is to be processed as a minor division, or as a subdivision or parcel division, there shall be counted as a parcel every parcel contiguous to that being created, or contiguous to a parcel created subsequent to September 20, 1963, which has at any time between that date up to and including April 27, 1971, been sold, leased, financed, given, conveyed, or transferred by the owner or subdivider.

(3) The provisions of subdivisions (E)(1) and (E)(2) of this section do not apply if (a) the subdivider and the owner at the time of creating such previously-created parcel or parcels had no present intent to create any additional parcels out of contiguous property, and (b) the subdivider and the owner execute and file with the Director of Planning and Building Services a notarized affidavit to that effect on a form to be prescribed by the Director.

(4) Notwithstanding the provisions of subdivision (E)(3), if the Subdivision Committee determines there are facts which reasonably warrant a suspicion that the subdivider or owner intended to create an additional parcel or parcels at the time of the subdivision referred to in subdivision (E)(3), the subdivider and the owner, in addition to filing an affidavit, shall have the burden of proving, by clear and convincing evidence presented to the Committee, that there was a lack of such present intent to create an additional parcel or parcels at the time of that subdivision.

Sec. 17-17.5. - Boundary Line Adjustment.

"Boundary line adjustment" means the transfer of property by deed to a respective owner or owners of contiguous property for the purpose of adjusting a boundary line and not for the purpose of creating an additional lot or parcel. In order for a transfer of property to be treated as a boundary line adjustment rather than as a division of land, there shall be submitted to the Director of Planning and Building Services a tentative map. The tentative map shall be clearly marked "Boundary Line Adjustment." The tentative map shall be a sketch clearly and legibly drawn. The minimum sheet size shall be eight and one-half (8½) by eleven (11) inches, and the scale shall be consistent with the content of the map. The tentative map of a proposed boundary line adjustment shall contain the following information:

(A) A site sketch showing the location of affected properties.

(B) Assessor's parcel numbers of affected properties.

(C) Names, addresses, and phone numbers of affected property owners and their agents.

(D) Date map was prepared, north point, and scale.

(E) The approximate location of all existing or proposed easements together with the purpose thereof.

(F) Proposed boundary line adjustment showing approximate location of existing and proposed property boundaries.

(G) When deemed applicable by the Subdivision Committee, the approximate location of important physical features which are within or adjacent to the affected properties including, but not limited to, public and private streets, existing buildings, lakes and ponds, springs, significant water courses, fences, wells, private sewage disposal systems, culverts, underground structures, overhead structures, major excavations, and mining shafts.

(H) The tentative map shall be reviewed by the Subdivision Committee, which may approve the boundary line adjustment proposed therein subject to whatever conditions it deems reasonable and that conform to Government Code Section 66412, subdivision (d), including requirements to insure that the adjustment shall not have the effect of creating a new lot or parcel. When completed, a boundary line adjustment shall extinguish all underlying parcels, parcel fragments, and parcel lines, whether created by deed, patent, previous boundary line adjustment, or previous county subdivision.

(I) A boundary line adjustment shall not be approved by the Committee, nor shall the deed or deeds completing the adjustment be recorded, until the chairman of the Committee has certified in writing that all of the conditions of approval have been satisfied, including:

(1) That the Assessor has been notified, by a combining agreement, of the pending changes in parcel configuration; and

(2) That the Treasurer-Tax Collector certifies that all taxes and assessments due on each parcel affected by the adjustment have been paid or cleared, and that a deposit to secure payment of the taxes and assessments which are due but not yet payable have been made.

(J) Within two (2) years after approval by the Subdivision Committee, the owner or owners shall cause a deed or deeds to be recorded which shall cause the boundary lines to be adjusted as approved. No parcel map need be filed in order to accomplish a boundary line adjustment. Land which has been affected by a boundary line adjustment shall not be deemed by that fact alone to have been divided.
