# §4022. State and local land use controls

- (a) **Requirement for participation in flood insurance program—**
  - (1) **In general—** After December 31, 1971, no new [flood](/usc/42/4121.md?p=a-1) insurance coverage shall be provided under this chapter in any area (or subdivision thereof) unless an appropriate public body shall have adopted adequate land use and control measures (with effective enforcement provisions) which the [Administrator](/usc/42/4003.md?p=a-6) finds are consistent with the comprehensive criteria for land management and use under [section 4102 of this title](/usc/42/4102.md).
  - (2) **Agricultural structures—**
    - (A) **Activity restrictions—** Notwithstanding any other provision of law, the adequate land use and control measures required to be adopted in an area (or subdivision thereof) pursuant to [paragraph (1)](#a-1) may provide, at the discretion of the appropriate [State](/usc/42/4121.md?p=a-2) or local authority, for the repair and restoration to predamaged conditions of an agricultural structure that—
      - (i) is a [repetitive loss structure](/usc/42/4121.md?p=a-7); or
      - (ii) has incurred [flood](/usc/42/4121.md?p=a-1)-related damage to the extent that the cost of restoring the structure to its predamaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred.
    - (B) **Premium rates and coverage—** To the extent applicable, an agricultural structure repaired or restored pursuant to [subparagraph (A)](#a-2-A) shall pay chargeable premium rates established under [section 4015 of this title](/usc/42/4015.md) at the estimated risk premium rates under [section 4014(a)(1) of this title](/usc/42/4014.md?p=a-1). If resources are available, the [Administrator](/usc/42/4003.md?p=a-6) shall provide technical assistance and counseling, upon request of the [owner](/usc/42/13641.md?p=4) of the structure, regarding wet [flood](/usc/42/4121.md?p=a-1)-proofing and other [flood](/usc/42/4121.md?p=a-1) damage reduction measures for agricultural structures. The [Administrator](/usc/42/4003.md?p=a-6) shall not be required to make [flood](/usc/42/4121.md?p=a-1) insurance coverage available for such an agricultural structure unless the structure is wet [flood](/usc/42/4121.md?p=a-1)-proofed through permanent or contingent measures applied to the structure or its contents that prevent or provide resistance to damage from flooding by allowing [flood](/usc/42/4121.md?p=a-1) waters to pass through the structure, as determined by the [Administrator](/usc/42/4003.md?p=a-6).
    - (C) **Prohibition on disaster relief—** Notwithstanding any other provision of law, any agricultural structure repaired or restored pursuant to [subparagraph (A)](#a-2-A) shall not be eligible for [disaster](/usc/42/5204.md?p=2) relief assistance under any program administered by the [Administrator](/usc/42/4003.md?p=a-6) or any other [Federal agency](/usc/42/4003.md?p=a-2).
    - (D) **Definitions—** For purposes of this paragraph—
      - (i) the term “agricultural structure” means any structure used exclusively in connection with the production, harvesting, storage, raising, or drying of agricultural commodities; and
      - (ii) the term “agricultural commodities” means agricultural commodities and livestock.
- (b) **Community rating system and incentives for community floodplain management—**
  - (1) **Authority and goals—** The [Administrator](/usc/42/4003.md?p=a-6) shall carry out a [community](/usc/42/4003.md?p=a-1) rating system program, under which [communities](/usc/42/4003.md?p=a-1) participate voluntarily—
    - (A) to provide incentives for measures that reduce the risk of [flood](/usc/42/4121.md?p=a-1) or erosion damage that exceed the criteria set forth in [section 4102 of this title](/usc/42/4102.md) and evaluate such measures;
    - (B) to encourage adoption of more effective measures that protect [natural and beneficial floodplain functions](/usc/42/4121.md?p=a-12);
    - (C) to encourage floodplain and erosion management; and
    - (D) to promote the reduction of Federal [flood](/usc/42/4121.md?p=a-1) insurance losses.
  - (2) **Incentives—** The program shall provide incentives in the form of credits on premium rates for [flood](/usc/42/4121.md?p=a-1) insurance coverage in [communities](/usc/42/4003.md?p=a-1) that the [Administrator](/usc/42/4003.md?p=a-6) determines have adopted and enforced measures that reduce the risk of [flood](/usc/42/4121.md?p=a-1) and erosion damage that exceed the criteria set forth in [section 4102 of this title](/usc/42/4102.md). In providing incentives under this paragraph, the [Administrator](/usc/42/4003.md?p=a-6) may provide for credits to [flood](/usc/42/4121.md?p=a-1) insurance premium rates in [communities](/usc/42/4003.md?p=a-1) that the [Administrator](/usc/42/4003.md?p=a-6) determines have implemented measures that protect [natural and beneficial floodplain functions](/usc/42/4121.md?p=a-12).
  - (3) **Credits—** The credits on premium rates for [flood](/usc/42/4121.md?p=a-1) insurance coverage shall be based on the estimated reduction in [flood](/usc/42/4121.md?p=a-1) and erosion damage risks resulting from the measures adopted by the [community](/usc/42/4003.md?p=a-1) under this program. If a [community](/usc/42/4003.md?p=a-1) has received mitigation assistance under [section 4104c of this title](/usc/42/4104c.md), the credits shall be phased in a manner, determined by the [Administrator](/usc/42/4003.md?p=a-6), to recover the amount of such assistance provided for the [community](/usc/42/4003.md?p=a-1).
  - (4) **Reports—** Not later than 2 years after September 23, 1994, and not less than every 2 years thereafter, the [Administrator](/usc/42/4003.md?p=a-6) shall submit a report to the Congress regarding the program under this subsection. Each report shall include an analysis of the cost-effectiveness of the program, any other accomplishments or shortcomings of the program, and any recommendations of the [Administrator](/usc/42/4003.md?p=a-6) for legislation regarding the program.
- (c) **Replacement of mobile homes on original sites—**
  - (1) **Community participation—** The placement of any mobile home on any site shall not affect the eligibility of any [community](/usc/42/4003.md?p=a-1) to participate in the [flood](/usc/42/4121.md?p=a-1) insurance program under this chapter and the [Flood](/usc/42/4121.md?p=a-1) [Disaster](/usc/42/5204.md?p=2) Protection Act of 1973 (notwithstanding that such placement may fail to comply with any elevation or [flood](/usc/42/4121.md?p=a-1) damage mitigation requirements), if—
    - (A) such mobile home was previously located on such site;
    - (B) such mobile home was relocated from such site because of flooding that threatened or affected such site; and
    - (C) such replacement is conducted not later than the expiration of the 180-day period that begins upon the subsidence (in the area of such site) of the body of water that flooded to a level considered lower than [flood](/usc/42/4121.md?p=a-1) levels.
  - (2) **Definition—** For purposes of this subsection, the term “mobile home” has the meaning given such term in the law of the [State](/usc/42/4121.md?p=a-2) in which the mobile home is located.
