§ 18.12.1702. Permit.

(a)

Building and/or Grading Permit Required. Any person desiring to construct, locate, extend, convert, or alter a structure or alter any land within any flood hazard areas (zones A, A1—30, AH, AE, and AO) or limited flooding area (shaded X) must obtain a building and/or grading permit and none of the exemptions to the building code in effect in the city shall apply to any such development. The city shall determine whether the proposed development is within any flood hazard areas (zone A, A1—30, AH, AE, and AO) or limited flooding area (shaded X). If so, the procedures and requirements set forth hereinafter must be satisfied before a building and/or grading permit is issued.

(b)

Responsibilities of the Owner or Developer.  

(1)

The owner or developer shall submit the following information for review by the city:

a.

The elevation of the base flood at the site(s) proposed for development.

b.

In A, A1—30, AH, and AE zones, proposed elevation in relation to mean sea level, certified by an engineer or surveyor, lowest point of the lowest horizontal member of the lowest floor of all structures; in zone AO, elevation of proposed finish grade and proposed elevation of lowest floor of all structures.

c.

Proposed elevation in relation to mean sea level to which any structure will be floodproofed, certified by an architect, engineer or land surveyor.

d.

Certification by an engineer that the proposed development will comply with the provisions for flood hazard reduction required in Section 18.12.1703.

e.

Description of the extent to which any watercourse will be altered or relocated as a result of proposed development, certified by an engineer. The altered watercourse shall have a flood-carrying capacity that is at least equal to the unaltered course that it replaces, and is to be certified to that effect by an engineer.

f.

An operation and maintenance plan for any and all flood protection measures, such as levees, dams, dikes, reservoirs, etc.

(2)

The owner or developer shall obtain a permit from the Nevada Division of State Lands before altering or relocating any waterway. This permit will be provided to the city.

(3)

Notify, in riverine situations, adjacent communities and the state coordinating office prior to altering or relocating any waterway, and submit copies of such notifications to the Federal Insurance Administrator (for the purpose of RMC 18.12.1702(b)(3) "community" means any state or area or political subdivision thereof, or any Indian tribe or authorized tribal organization, or authorized native organization, which has authority to adopt and enforce floodplain management regulations for the areas within its jurisdiction).

(4)

The owner or developer shall provide the city with certification by an engineer that all development was completed in compliance with the provisions of this article and all other applicable city codes.

(c)

Responsibilities of the City.  

(1)

The city will review all permit applications to determine:

a.

That the requirements of this article have been satisfied.

b.

That the site is reasonably safe from flooding.

c.

That the cumulative effect of the proposed development when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point.

d.

That the flood discharge volume and velocity exiting the development after construction is equal to or less than the flood discharge at the location prior to development and that no property upstream or downstream will be subject to increased flood levels or velocities as a result of the development.

e.

That all required state and federal permits have been obtained by the applicant.

(2)

The city will maintain for public inspection and make available as needed for flood insurance policies all certifications required in this article.

(3)

The city will provide interpretations, where needed, as to the location of the boundaries of the flood hazard areas and limited flooding areas, and the elevation of the base flood.

(4)

When base flood elevation data has not been provided in accordance with Section 18.12.1701(c), the city shall obtain, review and reasonably utilize any base flood elevation data available from a federal, state, or other source in order to administer Section 18.12.1703. The city may require that the developer provide an engineering study which determines the base flood elevation.

(5)

The city will maintain on file in the Floodplain Administrator's office all operation and maintenance plans submitted by the developer for any and all flood protection measures.
