2. Require that uses vulnerable to floods, including community facilities, be protected against flood damage

3. Control the alteration of natural floodplains, stream channels, and natural protective barriers that accommodate flood waters

4. Control filling, grading, dredging and other development that may increase erosion or flood damage

5. Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards.

D. Objectives –

The objectives of this Ordinance are:

1. To protect the health, safety, and general welfare of it citizenry.

2. To minimize expenditure of public funds for costly flood control projects

3. To minimize the need for rescue and relief efforts associated with flooding

(3) In or outside of an existing or new manufactured home park or subdivision, or in an expansion of an existing manufactured home park or subdivision, on which a manufactured home has incurred "substantial damage" as the result of a flood, any manufactured home placed or substantially improved must meet the standards of Section 3.

(4) All manufactured homes must be securely anchored to an adequately anchored foundation system to resist flotation, collapse and lateral movement.

(5) All recreational vehicles placed on identified flood hazard sites must either:

(a) Be on the site for fewer than 180 consecutive days;

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

(c) The recreational vehicle must meet all the requirements for new construction, including the anchoring and elevation requirements of this section above if on the site for longer than 180 consecutive days.

(d). Absent base flood elevations the manufactured home chassis is elevated and supported by reinforced piers (or other foundation elements) at least three (3) feet in height above the highest adjacent grade.

3. Standards For Areas Of Special Flood Hazard Zones AE With Established Base Flood Elevation But Without Floodways Designated -
Located within the areas of special flood hazard established in Section 3, where streams exist with base flood data provided but where no floodways have been provided, (Zone AE) the following provisions apply:

a. Certification for Encroachments - No encroachments, including fill material, new structures or substantial improvements shall be located within areas of special flood hazard, unless certification by a registered professional engineer is provided demonstrating 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 (1) foot at any point within the community. The engineering certification should be supported by technical data that conforms to standard hydraulic engineering principles.

b. Elevating or Flood-proofing - New construction or substantial improvements of buildings shall be elevated or flood-proofed to elevations established in accordance with Section 3.

4. Standards for Areas of Shallow Flooding (AO And AH Zones) - Located within the areas of special flood hazard established in Section 3 are areas designated as shallow flooding areas. These areas have special flood hazards associated with base flood depths of one to three feet (l' - 3') where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate; therefore, the following provisions apply:

a. All new construction and substantial improvements of residential buildings and non-residential buildings shall have the lowest floor, including basement, elevated to at least one (1’) foot above the flood depth number specified on the Flood Insurance Rate Map, in feet, above the highest adjacent grade. If no flood depth number is specified, the lowest floor, including basement, shall be elevated, at least three (3) feet above the highest adjacent grade. Openings sufficient to facilitate the unimpeded movements of floodwaters shall be provided in accordance with standards of section 3 and “elevated buildings".

b. All new construction and substantial improvements of nonresidential buildings may be flood-proofed in lieu of elevation. the structure together with attendant utility and sanitary facilities must be flood proofed and designed water tight to be completely flood proofed to at least one (1’) foot above the specified firm flood level with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy.

(1) If no depth number is specified, the lowest floor, including basement, shall be flood proofed to at least three (3) feet above the highest adjacent grade. A registered professional engineer or architect shall certify that the design and methods of construction are in accordance with accepted standards of practice for meeting the provisions of this ordinance and shall provide such certification to the city engineer as set forth above and as required in section 3.

(2) Adequate drainage paths shall be provided around slopes to guide floodwaters around and away from proposed structures.

(3) The administrator shall certify the elevation or the highest adjacent grade, where applicable, and the record shall become a permanent part of the permit file.

c. Drainage Paths - Adequate drainage paths shall be provided around slopes to guide floodwaters around and away from proposed structures.

5. Standards for Areas Protected by Flood Protection System (A-99 Zones) -
Located within the areas of special flood hazard established in Section 3.B are areas of the 100-year floodplain protected by a flood protection system but where base flood elevations and flood hazard factors have not been determined. Within these areas (A-99 Zones), all provisions of Sections 3 shall apply.

6. Standards for Areas of Special Flood Hazard with Established Base Flood Elevation and With Floodways Designated - Located within the areas of special flood hazard established in Section 3 are areas designated as floodways. A floodway may be an extremely hazardous area due to the velocity of floodwaters, debris or erosion potential. In addition, the area must remain free of encroachment in order to allow for discharge of the base flood without increased flood heights and velocities. Therefore the following provisions shall apply:

a. Encroachments are prohibited, including earthen fill material, new construction, substantial improvements or other developments within the regulatory floodway. Development may be permitted however, provided it is demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practices that the cumulative effect of the proposed encroachments or new development, when combined with all other existing and anticipated development, shall not result in any increase the water surface elevation of the base flood level, velocities or floodway widths during the occurrence of a base flood discharge at any point within the community. A registered professional engineer must provide supporting technical data and certification thereof.

b. New construction or substantial improvement of buildings shall comply with all applicable flood hazard reduction provision of section 3.


6.Standards for Areas Of Special Flood Hazard With Established Base Flood Elevations But Without Floodways Designated (AE Zones)- Located within the City of Lakeland established in Section 3 where streams exist with base flood data provided but where no floodways have been designated (Zones AE) the following provisions apply

a. No encroachments, including fill material, new structures or substantial improvements shall be located within areas of special flood hazard, unless certification by a registered professional engineer is provided demonstrating 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 (1) foot an any point within the community. The engineering certification should be supported by technical data that conforms to standard hydraulic engineering principles

b. New construction or substantial improvements of buildings shall be elevated or flood-proofed to elevations established in accordance with Section 3.


8. Standards For Streams Without Established Base Flood Elevations Or Floodways (A Zones)

Located within the areas of special flood hazard established in article iii, where streams exist, but no base flood data has been provided (A Zones), or where a floodway has not been delineated, the following provisions shall apply:

a. When base flood elevation data or floodway data have not been provided in accordance with section 3, then the city engineer shall obtain, review and reasonably utilize any scientific or historic base flood elevation and floodway data available from a federal, state or other source, in order to administer the provisions of section 3. Only if data is not available from these sources, then the following provisions (b & c) shall apply:

b. No encroachments, including structures or fill material, shall be located within an area equal to the width of the stream or twenty feet, whichever is greater, measured from the top of the stream bank, unless certification by registered professional engineer is provided demonstrating 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 (1) foot at any point within the community. The engineering certification should be supported by technical data that conforms to standard hydraulic engineering principles.



c. In special flood hazard areas without base flood elevation data, new construction or substantial improvements of existing shall have the lowest floor of the lowest enclosed area (including basement) elevated no less than three (3) feet above the highest adjacent grade at the building site. Openings sufficient to facilitate the unimpeded movements of floodwaters shall be provided in accordance with the standards of Section 3 and “elevated buildings".

9. Standards for Subdivision - Subdivisions and other proposed new developments, including manufactured home parks or subdivisions, shall be reviewed to determine whether such proposals will be reasonably safe from flooding. All subdivision proposals shall be consistent with the need to minimize flood damage. If a subdivision proposal or other proposed new development is in a flood-prone area, any such proposals shall be reviewed to ensure that:

a. Public Utilities and Facilities - 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.

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

c. Base Flood Elevation Data - Base flood elevation data shall be provided for subdivision proposals and other proposed development (including manufactured home parks and subdivisions) which is greater than fifty lots and/or five acres.

d. Streets - The lowest point of all subdivision streets shall be no less than 12 inches above base flood elevations.

e. Design - Subdivision designs will include a routing of the 100 year storm through the development. Minimum finish floor elevations will be set by the developer’s engineer on critical lots to ensure 12 inches above the 100 year storm is maintained.

D. Variance Procedures - The provisions of this section shall apply exclusively to areas of special flood hazard.

1. Board of Appeals –

a. The City of Lakeland Board of Appeals shall hear and decide appeals and requests for variances from the requirements of this Chapter.

b. Variances may be issued for the repair or rehabilitation of historic structures (see definition) upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum to preserve the historic character and design of the structure.

c. In passing upon such applications, the Board of Appeals shall consider all technical evaluations, all relevant factors, all standards specified in other sections of this Ordinance, and:

(1) The danger that material may be swept onto other property to the injury of others.

(2) The danger to life and property due to flooding or erosion;

(3) The susceptibility of the proposed facility and its contents to flood damage;

(4) The importance of the services provided by the proposed facility to the community.

(5) The necessity of the facility to a waterfront location, in the case of a functionally dependent facility;

(6) The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use.

(7) The relationship of the proposed use to the comprehensive plan and floodplain management program for that area.

(8) The safety of access to the property in times of flood for ordinary and emergency vehicles;

(9) The expected heights, velocity, duration, rate of rise and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site, and;

(10) The costs of providing governmental services during and after flood conditions including maintenance and repair of public utilities and facilities such as sewer, gas, electrical, and water systems, and streets and bridges.

d. Upon consideration of the factors listed above, and the purposes of this Ordinance, the Board of Appeals may attach such conditions to the granting of variances, as it deems necessary to effectuate the purposes of this Ordinance.

e. Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.

2. Conditions For Variances -
a. Minimum Relief Necessary - Variances shall be issued upon a determination that the variance is the minimum relief necessary, considering the flood hazard; and in the instance of a historical building, a determination that the variance is the minimum relief necessary so as not to destroy the historic character and design of the building.

b. Justification of Need - Variances shall only be issued upon (1) a showing of good and sufficient cause, (2) a determination that failure to grant the variance would result in exceptional hardship; and (3) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisance, cause fraud on or victimization of the public, or conflict with existing local laws or Ordinances.

c. Written Notice - Any applicant to whom a variance is granted shall be given written notice that the issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance, and that such construction below the base flood level increases risks to life and property.

d. Record Keeping and Reporting - The City Engineer shall maintain the records of all appeal actions and report any variances to the Federal Emergency Management Agency upon request.

Section 3. This Ordinance shall take effect fifteen (15) days after its final passage and publication, the public welfare requiring it.
