§ 330-10

Introduction

The flood hazard areas of Paulding County, Georgia are subject to periodic inundation which may result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood relief and protection, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare.

Flood hazard areas can serve important stormwater management, water quality, streambank protection, stream corridor protection, wetland preservation and ecological purposes when permanently protected as undisturbed or minimally disturbed areas.

Effective floodplain management and flood hazard protection activities can: (1) Protect human life and health; (2) Minimize damage to private property; (3) Minimize damage to public facilities and infrastructure such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; and (4) Minimize expenditure of public money for costly flood control projects associated with flooding and generally undertaken at the expense of the general public.

Article IX, Section II of the Constitution of the State of Georgia and O.C.G.A. § 36-1-20(a) have delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. Therefore, Paulding County, Georgia, does ordain this Chapter and establishes this set of floodplain management and flood hazard reduction provisions for the purpose of regulating the use of flood hazard areas. It is determined that the regulation of flood hazard areas and the prevention of flood damage are in the public interest and will minimize threats to public health and safety, as well as to private and public property.

§ 330-20

General Provisions

330-20.01 Purpose and Intent.

The purpose of Chapter 330 is to protect, maintain and enhance the public health, safety, environment and general welfare and to minimize public and private losses due to flood conditions in flood hazard areas, as well as to protect the beneficial uses of floodplain areas for water quality protection, streambank and stream corridor protection, wetlands preservation and ecological and environmental protection by provisions designed to:

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

B.Restrict or prohibit uses which are dangerous to health, safety and property due to flooding or erosion hazards, or which increase flood heights, velocities, or erosion;

C.Control filling, grading, dredging and other development which may increase flood damage or erosion;

D.Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands;

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

F.Protect the stormwater management, water quality, streambank protection, stream corridor protection, wetland preservation and ecological functions of natural floodplain areas.

330-20.02 Applicability.

Chapter 330 shall be applicable to all areas within unincorporated Paulding County, Georgia.

330-20.03 Designation of Ordinance Administrator.

The Paulding County Community Development Director or the Director's designee is hereby appointed to administer and implement the provisions of Chapter 330.

330-20.05 Compatibility with other Regulations.

Chapter 330 is not intended to modify or repeal any other ordinance, rule, regulation, statute, easement, covenant, deed restriction or other provision of law.

The requirements of Chapter 330 are in addition to the requirements of any other ordinance, rule, regulation or other provision of law, and where any provision of Chapter 330 imposes restrictions different from those imposed by any other ordinance, rule, regulation or other provision of law, whichever provision is more restrictive or impose higher protective standards for human health or the environment shall control.

330-20.06 Severability.

If the provisions of any section, subsection, paragraph, subdivision or clause of Chapter 330 shall be adjudged invalid by a court of competent jurisdiction, such judgment shall not affect or invalidate the remainder of any section, subsection, paragraph, subdivision or clause of Chapter 330.

330-20.07 Warning and Disclaimer of Liability.

The degree of flood protection required by Chapter 330 is considered reasonable for regulatory purposes and is based on scientific and engineering considerations.

Larger floods can and will occur; flood heights may be increased by manmade or natural causes. Chapter 330 does not imply that land outside the areas of special flood hazard or uses permitted within such areas will be free from flooding or flood damages. Chapter 330 shall not create liability on the part of Paulding County or by any officer or employee thereof for any flood damages that result from reliance on Chapter 330 or any administrative decision lawfully made thereunder.

Site: The parcel of land being developed, or the portion thereof on which the development project is located.

Start of Construction: Includes substantial improvement, and means the date the permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition placement, or other improvement was within 180 days of the permit date. The actual start means either the first placement of permanent construction of the structure on a site, such as the pouring of slabs or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include initial land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or part of the main structure. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.

Structure: A walled and roofed building (including a gas or liquid storage tank), that is principally above ground, or a manufactured home.

Subdivision: The division of a tract or parcel of land resulting in one or more new lots or building sites for the purpose, whether immediately or in the future, of sale, other transfer of ownership or land development, and includes divisions of land resulting from or made in connection with the layout or development of a new street or roadway or a change in an existing street or roadway.

Substantial Damage: Means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. This term also includes repetitive loss.

Substantial Improvement: Any reconstruction, rehabilitation, addition, or other improvement to a structure, taking place during a 10-year period, in which the cumulative cost equals or exceeds 50 percent of the market value of the structure prior to the improvement. The market value of the building means (1) the appraised value of the structure prior to the start of the initial repair or improvement, or (2) in the case of damage, the value of the structure prior to the damage occurring. This term includes structures which have incurred "substantial damage," regardless of the actual repair work performed. The term does not, however, include those improvements of a structure required to comply with existing state or local health, sanitary, or safety code specifications which are the minimum necessary to assure safe living conditions, which have been identified by the Code Enforcement Official. The term does also not include any alteration of a historic structure, provided that the alteration will not preclude the structure’s continued designation as a historic structure.

Substantially Improved Existing Manufactured Home Park or Subdivision: Is where the repair, reconstruction, rehabilitation or improvement of the streets, utilities and pads equals or exceeds 50 percent of the value of the streets, utilities and pads before the repair, reconstruction or improvement commenced.

Variance: A grant of relief from the requirements of Chapter 330.

Violation: The failure of a structure or other development to be fully compliant with the requirements of Chapter 330. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in Chapter 330 is presumed to be in violation until such time as that documentation is provided.

§ 330-50

Standards for Development

330-50.01 Definition of Floodplain Boundaries.

A.Studied "A" zones, as identified in the FIS, shall be used to establish base flood elevations whenever available.

B.For all streams with a drainage area of 100 acres or greater, the future-conditions flood elevations shall be provided by the director or director’s designee. If future-conditions elevation data is not available from the director or director’s designee, then it shall be determined by a licensed Professional Engineer using a method approved by FEMA and the director or director’s designee.

330-50.02 Definition of Floodway Boundaries.

The width of a floodway shall be determined from the FIS or FEMA approved flood study. For all streams with a drainage area of 100 acres or greater, the regulatory floodway shall be provided by the director or director’s designee. If floodway data is not available from the director or director’s designee, then it shall be determined by a licensed Professional Engineer using a method approved by FEMA and the director or director’s designee.

330-50.03 General Standards.

A.No development shall be allowed within any area of special flood hazard or area of future-conditions flood hazard that could result in any of the following:

1.Raising the base flood elevation or future-conditions flood elevation equal to or more than 1.0 foot;

2.Reducing the base flood or future-conditions flood storage capacity;

3.Changing the flow characteristics as to the depth and velocity of the waters of the base flood or future-conditions flood as they pass both the upstream and the downstream boundaries of the development area; or

4.Creating hazardous or erosion-producing velocities or resulting in excessive sedimentation.

B.Any development within any area of special flood hazard or area of future-conditions flood hazard allowed under Section 330-50.03(A) shall also meet the following conditions:

1.Compensation for storage capacity shall occur between the average ground water table elevation and the base flood elevation for the base flood, and between the average ground water table elevation and the future-condition flood elevation for the future-conditions flood, and lie either within the boundaries of ownership of the property being developed and shall be within the immediate vicinity of the location of the encroachment.

Acceptable means of providing required compensation include lowering of natural ground elevations within the floodplain, or lowering of adjoining land areas to create additional floodplain storage. In no case shall any required compensation be provided via bottom storage or by excavating below the elevation of the natural (pre-development) stream channel unless such excavation results from the widening or relocation of the stream channel;

2.Cut areas shall be stabilized and graded to a slope of no less than 2.0%;

3.Effective transitions shall be provided such that flow velocities occurring on both upstream and downstream properties are not increased or decreased;

4.Verification of no-rise conditions (less than 1.0 foot), flood storage volumes, and flow characteristics shall be provided via a step-backwater analysis meeting the requirements of Section 330-50.04;

5.Public utilities and facilities, such as water, sanitary sewer, gas, and electrical systems, shall be located and constructed to minimize or eliminate infiltration or contamination from flood waters; and

6.Any significant physical changes to the base flood floodplain shall be submitted as a Conditional Letter of Map Revision (CLOMR) or Conditional Letter of Map Amendment (CLOMA), whichever is applicable. The CLOMR submittal shall be subject to approval by the director or director’s designee using the FEMA community concurrence forms before forwarding the submittal package to FEMA for final approval. The responsibility for forwarding the CLOMR to FEMA and for obtaining the CLOMR approval shall be the responsibility of the applicant. Within six months of the completion of development, the applicant shall submit as-built surveys and plans for a final letter of map revision (LOMR).

330-50.04 Engineering Study Requirements for Floodplain Encroachments.

An engineering study is required, as appropriate to the proposed development activities on the site, whenever a development proposes to disturb any land within the future-conditions floodplain, except for a residential single-lot development on streams without established base flood elevations and floodways. This study shall be prepared by a licensed Professional Engineer and made a part of the application for a permit. This information shall be submitted to and approved by the director or director’s designee prior to the approval of any permit which would authorize the disturbance of land located within the future-conditions floodplain. Such study shall include:

A.Description of the extent to which any watercourse or floodplain will be altered or relocated as a result of the proposed development;

B.Step-backwater analysis, using a FEMA-approved methodology approved by the director or director’s designee. Cross-sections (which may be supplemented by the applicant) and flow information will be obtained whenever available. Computations will be shown duplicating FIS results and will then be rerun with the proposed modifications to determine the new base flood profiles, and future-conditions flood profiles;

C.Floodplain storage calculations based on cross-sections (at least one every 100 feet) showing existing and proposed floodplain conditions to show that base flood floodplain and future-conditions floodplain storage capacity would not be diminished by the development;

D.The study shall include a preliminary plat, grading plan, or site plan, as appropriate, which shall clearly define all future-conditions floodplain encroachments.

330-50.05 Floodway Encroachments.

Located within areas of special flood hazard are areas designated as floodway. A floodway may be an extremely hazardous area due to velocity flood waters, debris or erosion potential. In addition, floodways must remain free of encroachment in order to allow for the discharge of the base flood without increased flood heights.

Therefore the following provisions shall apply:

A.Encroachments are prohibited, including earthen fill, new construction, substantial improvements or other development within the regulatory floodway, except for activities specifically allowed in 330-50.05.B.

B.Encroachments for bridges, culverts, roadways and utilities within the regulatory floodway may be permitted provided it is demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the encroachment will not result in any increase to the pre-project base flood elevations, floodway elevations, or floodway widths during the base flood discharge. A licensed professional engineer must provide supporting technical data and certification thereof; and

C.If the applicant proposes to revise the floodway boundaries, no permit authorizing the encroachment into or an alteration of the floodway shall be issued by the director or director’s designee until an affirmative Conditional Letter of Map Revision (CLOMR) is issued by FEMA and no-rise certification is approved by Paulding County.

330-50.06 Maintenance Requirements.

The property owner shall be responsible for continuing maintenance as may be needed within an altered or relocated portion of a floodplain on his property so that the flood-carrying or flood storage capacity is not diminished. Paulding County may direct the property owner (at no cost to Paulding County) to restore the flood-carrying or flood storage capacity of the floodplain if the owner has not performed maintenance as required by the approved floodplain management plan on file with Paulding County.

§ 330-60

Provisions for Flood Damage Reduction

In all areas of special flood hazard and areas of future-conditions flood hazard the following provisions apply:

330-60.01 General Standards.

A.New construction and substantial improvements of structures (residential or nonresidential), including manufactured homes, shall not be allowed within the limits of the future-conditions floodplain, unless all requirements of sections 330-50.03, 330-50.04 and 330-50.05 have been met;

B.New construction and substantial improvements shall be anchored to prevent flotation, collapse and lateral movement of the structure;

C.New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage;

D.New construction and substantial improvements shall be constructed by methods and practices that minimize flood damage;

E.Elevated Buildings. All new construction and substantial improvements that include any fully enclosed area located below the lowest floor formed by foundation and other exterior walls shall be designed so as to be an unfinished or flood resistant enclosure.

Variances

330-70.01 Variance Procedures.

The following variance and appeals procedures shall apply to an applicant who has been denied a permit for a development activity or to an owner or developer who has not applied for a permit because it is clear that the proposed development activity would be inconsistent with the provisions of Chapter 330. A request for a variance may be submitted by an applicant who has been denied a permit by the Paulding County Community Development Department or by an owner or developer who has not previously applied for a permit for the reasons stated herein above.

A.Any person aggrieved by a decision or order of the Paulding County Community Development Department, may appeal in writing within 30 days after the issuance of such decision or order to the Paulding County Development Waiver Review Committee in accordance with the Administration article of the development regulations. The party appealing such decision shall be entitled to a hearing before the Paulding County Development Waiver Review Committee, as set forth in the administration article of the development regulations, within 30 days of receipt of the written appeal or at the next regularly scheduled meeting of the Development Waiver Review Committee.

B.Any person aggrieved by the decision of the Paulding County Development Waiver Review Committee may appeal such decision to the Paulding County Board of Commissioners, as provided in O.C.G.A. § 5-4-1.

C.Any person aggrieved by the decision of the Paulding County Board of Commissioners may appeal such decision to a court of competent jurisdiction, as provided in O.C.G.A. § 5-4-1.

D.Variances may be issued for the repair or rehabilitation of historic structures upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure, and the variance issued shall be the minimum necessary to preserve the historic character and design of the structure.

E.Variances may be issued for development necessary for the conduct of a functionally dependent use, provided the criteria of this section are met, no reasonable alternative exists, and the development is protected by methods that minimize flood damage during the base flood and create no additional threats to public safety.

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

G.In reviewing such requests, the Paulding County Development Waiver Review Committee and Paulding County Board of Commissioners shall consider all technical evaluations, relevant factors, and all standards specified in this and other sections of Chapter 330.

H.A variance shall be issued only when there is:

1.A finding 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, or the creation of a nuisance.

I.The provisions of Chapter 330 are minimum standards for flood loss reduction; therefore, any deviation from the standards must be weighed carefully. Variances shall only be issued upon determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

J.Any person to whom a variance is granted shall be given written notice specifying the difference between the base flood elevation and the elevation of the proposed lowest floor and stating that the cost of flood insurance resulting from the lowest floor elevation being placed below the base flood elevation will be commensurate with the increased risk to life and property, and that such costs may be as high as $25.00 for each $100.00 of insurance coverage provided.

K.The Director or Director’s designee shall maintain the records of all variance actions, both granted and denied, and report them to the Georgia Department of Natural Resources and the Federal Emergency Management Agency upon request.

L.Any person requesting a variance shall, from the time of the request until the time the request is acted upon, submit such information and documentation as the Paulding County Community Development Director and Paulding County Development Waiver Review Committee shall deem necessary to the consideration of the request.

Title 3: Chapter 330

M.Upon consideration of the factors listed above and the purposes of Chapter 330, the Paulding County Community Development Director and the Paulding County Development Waiver Review Committee may attach such conditions to the granting of variances as they deem necessary or appropriate, consistent with the purposes of Chapter 330.

N.Variances shall not be issued "after the fact."
