A minimum of 60 percent of the landscape elements utilized on a parcel that is between one-half and five acres shall be drought tolerant native species. Total landscape elements, excluding turf, shall not be comprised of more than 30 percent of any single species or 50 percent of any genus.

(3)

A minimum of 75 percent of the landscape elements utilized on a parcel that is greater than five acres shall be drought tolerant native species. Total landscape elements, excluding turf, shall not be comprised of more than 20 percent of any single species or 25 percent of any genus.

(H)

Tree Preservation. Preservation of existing high-quality trees within a new development or redevelopment site is highly encouraged. Preserved trees may fulfill a portion of the landscape requirements established in this section. Should the developer propose to maintain existing high-quality trees to count toward satisfying certain landscape requirements of this UDO, the City Planner may, upon receipt of a tree preservation plan, waive certain landscape requirements if mature, high quality trees on a lot are proposed to be preserved. If, upon inspection at the conclusion of the project, trees identified for preservation have been removed, damaged, or are otherwise in declining condition, all waived required landscape shall be installed.

(A)

Statutory Authorization. The Legislature of the State of Oklahoma has in (statutes) 82 O.S., §§ 1601—1620 delegated the responsibility of local governmental units to adopt regulations designed to minimize flood losses. Therefore, the City of Jenks, Oklahoma, City Council does ordain as is set out in the provisions of this section.

(B)

Findings of Fact.

(1)

The flood hazard areas of the City of Jenks are subject to periodic inundation that results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief, all of which adversely affect the public health, safety and general welfare.

(2)

These flood losses are created by the cumulative effect of obstructions in floodplains which cause an increase in flood heights and velocities, and by the occupancy of flood hazard areas by uses vulnerable to floods and hazardous to other lands because they are inadequately elevated, floodproofed or otherwise protected from flood damage.

(C)

Statement of Purpose. It is the purpose of this section to promote the public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to:

(1)

Protect human life and health;

(2)

Minimize expenditure of public money for costly flood control projects;

(3)

Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;

(4)

Minimize prolonged business interruptions;

(5)

Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains;

(6)

Help maintain a stable tax base by providing for the sound use and development of flood prone areas in such a manner as to minimize future flood blight areas; and

(7)

Ensure that potential buyers are notified that property is in a flood area.

(D)

Methods of Reducing Flood Loss. In order to accomplish its purposes, this section uses the following methods:

(1)

Restrict or prohibit uses that are dangerous to health, safety or property in times of flood, or cause excessive increases in flood heights or velocities;

(2)

Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;

(3)

Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters;

(4)

Control filling, grading, dredging and other development which may increase flood damage; and

(5)

Prevent or regulate the construction of flood barriers which will unnaturally divert floodwaters, or which may increase flood hazards to other lands.

(E)

Lands to Which This Section Applies. This Section shall apply to all areas of special flood hazard within the jurisdiction of the City of Jenks, Oklahoma.

(F)

Basis For Establishing the Areas of Special Flood Hazard.

(1)

The areas of special flood hazard identified by the Federal Emergency Management Agency in a scientific and engineering report entitled, "The Flood Insurance Study for Tulsa County, Oklahoma and Incorporated Areas" dated May 2, 2019, with accompanying Flood Insurance Rate Map (FIRM) are hereby referenced to be effective on October 16, 2012 and before, along with any future revisions thereof that are individually adopted by the Jenks City Council are hereby adopted by reference and declared to be a part of this section.

(2)

That all provisions of the flood management regulations of Section 60.3(d) of the National Flood Insurance Program (44 CFR 59 et seq.) as amended are hereby incorporated by reference and will determine standards for development unless existing Jenks ordinances or state requirements impose a higher standard, in which event the higher or restrictive standard shall apply.

(G)

Establishment of Development Permit. A development permit shall be required to ensure conformance with the provisions of this article.

(H)

Compliance. No structure or land shall hereafter be located, altered, or have its use changed without full compliance with the terms of this section and other applicable regulations.

(I)

Abrogation and Greater Restrictions. This section is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this section and another ordinance, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.

(J)

Interpretation. In the interpretation and application of this section, all provisions shall be:

(1)

Considered as minimum requirements;

(2)

Liberally construed in favor of the governing body; and

(3)

Deemed neither to limit nor repeal any other powers granted under State statutes.

(K)

Warning and Disclaimer of Liability. The degree of flood protection required by this section is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. On rare occasions greater floods can and will occur and flood heights may be increased by manmade or natural causes. This Section does not imply that land outside the areas of special flood hazards or uses permitted within such areas will be free from flooding or flood damages. This Section shall not create liability on the part of the community or any official or employee thereof for any flood damages that result from reliance on this section or any administrative decision lawfully made hereunder.

A recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities and security devices, and has no permanently attached additions.

(N)

Standards For Subdivision Proposals.

(1)

All subdivision proposals including the placement of manufactured home parks and subdivisions shall be consistent with section 16-6-8(B), (C), and (D).

(2)

All proposals for the development of subdivisions shall meet development permit requirements of section[s] 16-6-8(G) and 16-9-5 and the provisions of this section.

(3)

Base flood elevation data shall be generated for subdivision proposals and other proposed development including the placement of manufactured home parks and subdivisions which is greater than 50 lots or five acres, whichever is lesser, if not otherwise provided pursuant to section 16-6-8(F).

(4)

All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hazards.

(5)

All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage.

(O)

Standards For Areas of Shallow Flooding.

(1)

Located within the areas of special flood hazard established in section 16-6-8(F), are areas designated as shallow flooding. These areas have special flood hazards associated with base flood depths of one to three feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and where velocity flows may be evident. Such flooding is characterized by ponding or sheet flow; therefore, the following provisions apply:

(a)

All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified).

(b)

All new construction and substantial improvements of nonresidential structures:

(I)

Have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified); or

(II)

Together with attendant utility and sanitary facilities be designed so that below the base flood level the structure is water-tight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads of effects of buoyancy.

(c)

A registered professional engineer or architect shall submit a certification to the Floodplain Administrator that the standards of this section are satisfied.

(d)

Require within Zones AH or AO adequate drainage paths around structures on slopes, to guide floodwaters around and away from proposed structures.

(P)

Floodways.

(1)

Floodways located within areas of special flood hazard established in section 16-6-8(F), are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of floodwaters that carry debris, potential projectiles and erosion potential, the following provisions shall apply:

(a)

Encroachments are prohibited, including fill, new construction, substantial improvements, and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge.

(b)

If subsection (1)(a) of this section is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of this section 16-6-8.

(c)

Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Regulations, a community may permit encroachments within the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the community first applies for a conditional FIRM and floodway revision through FEMA.
