For purposes of determining whether contiguous parcels are held by the same owner, ownership shall be determined as of the date that notice of intention to determine status is reported.

  • C. Procedure; Merger of Parcels.

    1. A merger of parcels becomes effective when the community development director causes to be filed for record with the county recorder a notice of merger specifying the names of the record owners and particularly describing the real property.

    2. Prior to recording a notice of merger, the community development director shall cause to be mailed by certified mail to the then current record owner of the property a notice of intention to determine status, notifying the owner that the affected parcels may be merged pursuant to standards specified by ordinance, and advising the owner of the opportunity to request a hearing on determination of status and to present evidence at the hearing that the property does not meet the criteria for merger. The notice of intention to determine status shall be filed for record with the county recorder on the date that notice is mailed to the property owner.

    3. At any time within thirty days after recording of the notice of intention to determine status, the owner of the affected property may file with the planning director a request for hearing on determination of status.

  1. Upon receiving a request for a hearing on determination of status, the community development director shall fix a date, time, and place for a hearing to be conducted by the director, and shall so notify the property owner by certified mail. The hearing shall be conducted not less than thirty days following the receipt by the community development director of the property owner's request therefor, but may be postponed or continued with the consent of the property owner.

    1. At the hearing, the property owner shall be given the opportunity to present any evidence that the affected property does not meet the standards for merger specified in subsection B of this section. At the conclusion of the hearing, the community development director shall make a determination that the affected parcels are to be merged or are not to be merged and shall so notify the owner of its determination. A determination of merger shall be recorded within thirty days after the conclusion of the hearing, as provided for in paragraph 1 of this subsection. The owner may appeal the decision pursuant to Chapter 12.64 .

    2. If, within the thirty day period specified in paragraph 3, the owner does not file a request for a hearing in accordance with paragraph 5, the community development director may, at any time thereafter, make a determination that the affected parcels are to be merged or are not to be merged. A determination of merger shall be recorded as provided for in paragraph 1 no later than ninety days following the mailing of notice required by paragraph 2.

  2. If, in accordance with paragraphs 5 or 6, it is determined that the subject property shall not be merged, the community development director shall cause to be recorded in the manner specified in paragraph 1 a release of the notice of intention to determine status, recorded pursuant to paragraph 2, and shall mail a clearance letter to the then current owner of record.
