§ 4015. Chargeable premium rates
(a)
Establishment; terms and conditions
On the basis of estimates made under section
4014 of this title, and such other information as may be necessary, the Director shall from time to time, after consultation with the advisory committee authorized under section
4025 of this title, appropriate representatives of the pool formed or otherwise created under section
4051 of this title, and appropriate representatives of the insurance authorities of the respective States, prescribe by regulation—
(b)
Considerations for rates
Such rates shall, insofar as practicable, be—
(1)
based on a consideration of the respective risks involved, including differences in risks due to land use measures, flood-proofing, flood forecasting, and similar measures.
(2)
adequate, on the basis of accepted actuarial principles, to provide reserves for anticipated losses, or, if less than such amount, consistent with the objective of making flood insurance available where necessary at reasonable rates so as to encourage prospective insureds to purchase such insurance and with the purposes of this chapter,
(c)
Actuarial rate properties
Subject only to the limitations provided under paragraphs (1) and (2), the chargeable rate shall not be less than the applicable estimated risk premium rate for such area (or subdivision thereof) under section
4014
(a)(1) of this title with respect to the following properties:
(1)
Post-firm properties
Any property the construction or substantial improvement of which the Director determines has been started after December 31, 1974, or started after the effective date of the initial rate map published by the Director under paragraph (2) of section
4101 of this title for the area in which such property is located, whichever is later, except that the chargeable rate for properties under this paragraph shall be subject to the limitation under subsection (e) of this section.
(2)
Certain leased coastal and river properties
Any property leased from the Federal Government (including residential and nonresidential properties) that the Director determines is located on the river-facing side of any dike, levee, or other riverine flood control structure, or seaward of any seawall or other coastal flood control structure.
(d)
Payment of certain sums to Director; deposits in Fund
With respect to any chargeable premium rate prescribed under this section, a sum equal to the portion of the rate that covers any administrative expenses of carrying out the flood insurance and floodplain management programs which have been estimated under paragraphs (1)(B)(ii) and (1)(B)(iii) of section
4014
(a) of this title or paragraph (2) of such section (including the fees under such paragraphs), shall be paid to the Director. The Director shall deposit the sum in the National Flood Insurance Fund established under section
4017 of this title.
(e)
Annual limitation on premium increases
Except with respect to properties described under paragraph (2) or (3) [1] of subsection (c) of this section, and notwithstanding any other provision of this chapter, the chargeable risk premium rates for flood insurance under this chapter for any properties within any single risk classification may not be increased by an amount that would result in the average of such rate increases for properties within the risk classification during any 12-month period exceeding 10 percent of the average of the risk premium rates for properties within the risk classification upon the commencement of such 12-month period.
(f)
Adjustment of premium
Notwithstanding any other provision of law, if the Director determines that the holder of a flood insurance policy issued under this chapter is paying a lower premium than is required under this section due to an error in the flood plain determination, the Director may only prospectively charge the higher premium rate.
