A.

Notice of intention to determine status of affected parcels. The city planner, or other person designated by the city manager, shall mail a notice of intention to determine the status of the affected parcels by certified mail to the then current owners of record. The notice shall advise the owner that the affected parcels may be merged under the standards specified in this chapter and advise the owner of the opportunity to request a hearing on the determination of status and to present evidence at the hearing that the affected parcels do not meet the criteria for merger.

B.

Recordation of notice of intention. The city planner, or other person designated by the city manager, shall file the notice of intention to determine status for record with the recorder of the county on the date that the notice is mailed to the property owner.

C.

Hearing. If the owner presents to the city planner, or other person designated by the city manager, a request for a hearing on determination of status within thirty days after recordation of the notice of intention to determine status, the city planner, or other person designated by the city manager, shall fix the time, date

and place for a hearing to be conducted by the planning commission. The city planner, or other person designated by the city manager, shall notify the owner by certified mail of the hearing. The planning commission shall conduct a hearing not less than thirty days after the city has received the property owner's request for a hearing. The hearing date may be postponed or continued with the mutual consent of the planning commission and the owner.

D.

Determination of status following hearing. At the hearing, the owner may present evidence that the affected parcels do not meet the standards for merger specified in this section. At the conclusion of the hearing, the planning commission shall determine whether the affected parcels are to be merged or are not to be merged, and shall notify the owner of its determination.

E.

Recordation of notice of merger. The city shall cause a notice of merger specifying the names of the record owners and particularly describing the real property to be recorded within thirty days after conclusion of the hearing.

F.

Determination of merger where no hearing requested. If, within the thirty-day period after recordation of the notice of intention to determine status, the owner of the affected parcel does not file a request for a hearing, the city engineer may make a determination that the affected parcels are to be merged or are not to be merged. A notice of merger shall be recorded not later than ninety days after the date when the department mailed the notice of intention to determine status.

G.

Determination not to merge. If the planning commission or city engineer determines that the affected parcels are not to be merged pursuant to this section, the city shall have recorded a release of the notice of intention to determine status and shall mail a clearance letter to the then current property owner of record. If a property owner initiates or consents in writing to a lot merger, the city engineer may cause the merger of the affected lots without referring the proposed merger to the planning commission for a public hearing.
