A. A major misfortune or calamity, in an area or region subsequently proclaimed by the Governor to be in a state of disaster, if that property was damaged or destroyed by the major misfortune or calamity that caused the Governor to proclaim the area or region to be in a state of disaster. As used in this paragraph, "damage" includes a diminution in the value of property as a result of restricted access to the property where that restricted access was caused by the major misfortune or calamity.

B. A misfortune or calamity.

4.20.100 - Three-year installment tax payment of increased or escaped assessments…

A. Purpose. The board of supervisors of the county hereby declares that this section is adopted to achieve the following purpose: To provide a means by which a taxpayer whose taxes have been increased because of a correction of an error, not that of the assessee, resulting in an increased assessment, either by way of a roll correction under the provisions of Section 4831 of the Revenue and Taxation Code of the state or an escaped assessment under the provisions of Section 531 of the Revenue and Taxation Code of the state, can pay the increased taxes over a three-year period when such increase constitutes a hardship on the assessee.

B. Finding of Hardship. Upon timely filing of a request for spreading of payments for taxes on assessments made pursuant to the provisions of either Sections 4331 et seq., Revenue and Taxation Code of the state or Sections 531 et seq. of the Revenue and Taxation Code of the state, the board of supervisors shall determine whether the error causing the increase in assessment was that of the assessee and whether such increase in assessment and corresponding increase in taxes constitutes a hardship on the assessee.

C. Payment.

  1. In those instances where the board of supervisors of the county has determined that the payment of taxes on the increased assessment constitutes a hardship on the assessee, the assessee may elect to pay increased taxes in installments under this section.

  2. Effect of Payments. During the time payments are made under this section, there shall not be:

a. A deed to the state for taxes,

b. Any termination of the right of redemption,

c. Any imposition of interest, delinquent penalties, redemption penalties, costs or fees.

  1. Amount of First Payment. Election to pay delinquent taxes installments is made by payment, in the same manner as a redemption of thirty-three and one-third (33⅓) percent, or more, of the increased taxes.

  2. Time of Payment. The payment of the first installment shall be within one year from the date of the resolution of the board of supervisors of the county increasing the amounts of the assessment which date shall be known as the anniversary date.

  3. Succeeding Amounts.

a. In each succeeding fiscal year the assessee shall pay all current taxes, penalties and costs, and any installment on a valid five-year installment plan for payment of prior year delinquent taxes coming due in that fiscal year before the delinquent date of the last installment of current original taxes.

b. In each succeeding fiscal year the assessee shall pay, before the anniversary date, the sum of the following:

i. That amount which is computed to be not less than the difference between the amounts previously paid under the provisions of this section, and

ii. Sixty-six and two-thirds (66⅔) percent of the increased taxes when the payment is made during or prior to the first fiscal year following the year in which election was made to pay delinquent taxes in installments.

iii. One hundred (100) percent of the increased taxes when the payment is made during or prior to the second fiscal year following the year in which election was made to pay delinquent taxes in installments.

Payments under this section are subject to receipting, accounting and deposit in the same manner as a regular redemption, except that no certificate of redemption will be issued on final payment unless such final payment cures all existing delinquent taxes on the property involved. Receipts issued for payments will reflect that the payments are for use of the real estate under this plan for payment of increased taxes in installments.

  1. Effect of Default. If all payments are not made on or before the dates prescribed all provisions of the Revenue and Taxation Code of the state relating to the collection of delinquent taxes apply.

  2. Concurrent Defaults.

a. A three-year plan for installment payments under this section shall default if the current original taxes and any valid five-year installment plan for payment of prior year taxes are not maintained in a current status.

b. Similarly, any valid five-year installment plan for payment of prior year delinquent taxes shall default if the current original taxes and any three-year plan for installment payments under this section are not maintained in a current status.

  1. Other Provisions.

a. A three-year plan for installment payments under this section shall be allowed only in those instances where (i) current original taxes are not delinquent, and (ii) all prior year delinquent taxes are established on a valid five-year installment payment plan pursuant to Article 2, Chapter 3, Part 7, Division 1 of the California Revenue and Taxation Code.

b. Any property covered hereunder in a tax delinquent status shall be sold to the state on or before June 30th (unless previously sold to the state and not redeemed) in the year in which the increased taxes are entered on the roll.

c. All current original taxes, with penalties thereon, and any installment on a five-year plan for payment of prior year delinquent taxes due or coming due in the fiscal year in which the first installment payment is made under the provisions of this section shall be paid before the delinquency date of the last installment of the current original taxes, except that if election to pay the increased taxes installment is made after the delinquency date of the last installment of current original taxes in any fiscal year, the current original taxes, with penalties and costs thereon, shall be paid with or prior to the installment payment herein authorized.

d. The treasurer-tax collector of the county of Alameda shall maintain a separate public record entitled "Three-year Installment Tax Payment for Use of Real Estate" listing the current status of all installment accounts authorized by this section.
