4.08.140 Development permit and certification requirements.

(1)

Development permit. Application for a development permit shall be made to the local floodplain administrator on forms furnished by him or her prior to any development activities. The development permit may include, but not be limited to, plans in duplicate drawn to scale showing: the nature, location, dimensions, and elevations of the area in question; existing or proposed structures; and the location of fill materials, storage areas, and drainage facilities. Specifically, the following information is required:

a.

A plot plan that shows the one hundred-year floodplain contour or a statement that the entire lot is within the floodplain must be provided by the development permit applicant when the lot is within or appears to be within the floodplain as mapped by the federal emergency management agency or the floodplain identified pursuant to either the duties and responsibilities of the local floodplain administrator of subsection 4.08.150(11) or the standards for subdivision proposals of section 4.08.180 and the standards for streams without estimated base flood elevations and floodways of section 4.08.190. The plot plan must be prepared by or under the direct supervision of a registered land surveyor or professional engineer and certified by it. The plot plan must show the floodway, if any, as identified by the Federal Emergency Management Agency or the floodway identified pursuant to either the duties or responsibilities of the local floodplain administrator of subsection 4.08.150(11) or the standards for subdivision proposals of subsection 4.08.180(12) and the standards for streams without estimated base flood elevations and floodways of section 4.08.190.

b.

Where base flood elevation data is provided as set forth in section 4.08.040 or the duties and responsibilities of the local floodplain administrator of subsection 4.08.150(11) the application for a development permit within the flood hazard area shall show:

1.

The elevation (in relation to mean sea level) of the lowest floor of all new and substantially improved structures, and

2.

If the structure will be floodproofed in accordance with the non-residential construction requirements of subsection 4.08.180(2) the elevation (in relation to mean sea level) to which the structure will be floodproofed.

c.

Where base flood elevation data is not provided as set forth in section 4.08.040 or the duties and responsibilities of the local floodplain administrator of subsection 4.08.150(11), then the provisions in the standards for streams without estimated base flood elevations and floodways of section 4.08.190 must be met.

d.

(2)

Certifications.

a.

Floodproofing certification. When a structure is floodproofed, the applicant shall provide certification from a registered, professional engineer or architect that the non-residential, floodproofed structure meets the floodproofing criteria in the non-residential construction requirements of subsection 4.08.180(2) and subsection 4.08.210(2)b.

b.

Certification during construction. A lowest floor elevation or floodproofing certification is required after the lowest floor is completed. As soon as possible after completion of the lowest floor and before any further vertical construction commences, or floodproofing by whatever construction means, whichever is applicable, it shall be the duty of the permit holder to submit to the local floodplain administrator a certification of the elevation of the lowest floor, or floodproofed elevation, whichever is applicable, as built, in relation to mean sea level. Said certification shall be prepared by or under the direct supervision of a registered land surveyor or professional engineer and certified by it. Any work done prior to submission of the certification shall be at the permit holder's risk. The local floodplain administrator shall review the floor elevation survey data submitted. The permit holder immediately and prior to further progressive work being permitted to proceed shall correct deficiencies detected by such review. Failure to submit the survey or failure to make said corrections required hereby shall be cause to issue a stop-work order for the project.

(3)

Watercourse alterations.

a.

Notify adjacent communities and the South Carolina Department of Natural Resources, Land, Water, and Conservation Division, State Coordinator for the National Flood Insurance Program, prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Emergency Management Agency.

b.

In addition to the notifications required watercourse alterations per subsection 4.08.150(3)a., written reports of maintenance records must be maintained to show that maintenance has been provided within the altered or relocated portion of said watercourse so that the flood-carrying capacity is maintained. This maintenance must consist of a comprehensive program of periodic inspections, and routine channel clearing and dredging, or other related functions. The assurance shall consist of a description of maintenance activities, frequency of performance, and the local official responsible for maintenance performance. Records shall be kept on file for FEMA inspection.

c.

If the proposed project will modify the configuration of the watercourse, floodway, or base flood elevation for which a detailed flood insurance study has been developed, the applicant shall apply for and must receive approval for a conditional letter of map revision with the Federal Emergency Management Agency prior to the start of construction.

d.

Within sixty days of completion of an alteration of a watercourse, referenced in the certification requirements of subsection 4.08.140(2)d., the applicant shall submit as-built certification, by a registered professional engineer, to the Federal Emergency Management Agency.

(4)

Floodway encroachments. Prevent encroachments within floodways unless the certification and flood hazard reduction provisions of subsection 4.08.180(5) are met.

(5)

Adjoining floodplains. Cooperate with neighboring communities with respect to the management of adjoining floodplains and/or flood-related erosion areas in order to prevent aggravation of existing hazards.

(6)

Notifying adjacent communities. Notify adjacent communities prior to permitting substantial commercial developments and large subdivisions to be undertaken in areas of special flood hazard and/or flood-related erosion hazards.

(7)

Certification requirements.

a.

Obtain and review actual elevation (in relation to mean sea level) of the lowest floor of all new or substantially improved structures, in accordance with administrative procedures outlined in subsection 4.08.140(2)b. or the coastal high hazard area requirements.

b.

Obtain the actual elevation (in relation to mean sea level) to which the new or substantially improved structures have been floodproofed, in accordance with the floodproofing certification outlined in subsection 4.08.140(2)a.

c.

When floodproofing is utilized for a particular structure, obtain certifications from a registered professional engineer or architect in accordance with the non-residential construction requirements outlined in subsection 4.08.180(2).

d.

A registered professional engineer or architect shall certify that the design, specifications and plans for construction are in compliance with the provisions contained in the coastal high hazard area requirements.

(8)

Map interpretation. Where interpretation is needed as to the exact location of boundaries of the areas of special flood hazard (for example, where there appears to be a conflict between a mapped boundary and actual field conditions), make the necessary interpretation. The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in this article.

(9)

Prevailing authority. Where a map boundary showing an area of special flood hazard and field elevations disagree, the base flood elevations for flood protection elevations (as found on an elevation profile, floodway data table, etc.) shall prevail. The correct information should be submitted to FEMA as per the map maintenance activity requirements outlined in subsection 4.08.180(7)b.

(10)

Use of best available data. When base flood elevation data and floodway data has not been provided in accordance with section 4.08.040, obtain, review, and reasonably utilize best available base flood elevation data and floodway data available from a federal, state, or other source, including data developed pursuant to the standards for subdivision proposals outlined in subsection 4.08.180(12), in order to administer the provisions of this chapter. Data from preliminary, draft, and final flood insurance studies constitutes best available data from a federal, state, or other source. Data must be developed using hydraulic models meeting the minimum requirement of NFIP approved model. If an appeal is pending on the study in accordance with 44 CFR Ch. 1, Parts 67.5 and 67.6, the data does not have to be used.

(11)

Special flood hazard area/topographic boundaries conflict. When the exact location of boundaries of the areas special flood hazards conflict with the current, natural topography information at the site; the site information takes precedence when the lowest adjacent grade is at or above the BFE, the property owner may apply and be approved for a letter of map amendment (LOMA) by FEMA. The local floodplain administrator in the permit file will maintain a copy of the letter of map amendment issued from FEMA.

(12)

On-site inspections. Make on-site inspections of projects in accordance with the administrative procedures outlined in subsection 4.08.160(1).

(13)

Administrative notices. Serve notices of violations, issue stop-work orders, revoke permits and take corrective actions in accordance with the administrative procedures in section 4.08.160.

(14)

Records maintenance. Maintain all records pertaining to the administration of this chapter and make these records available for public inspection.

(15)

Annexations and detachments. Notify the South Carolina Department of Natural Resources Land, Water and Conservation Division, State Coordinator for the National Flood Insurance Program within six months, of any annexations or detachments that include special flood hazard areas.

(16)

Federally funded development. The President issued Executive Order 11988, floodplain management May 1977. E.O. 11988 directs federal agencies to assert a leadership role in reducing flood losses and losses to environmental values served by floodplains. Proposed developments must go through an eight-step review process. Evidence of compliance with the executive order must be submitted as part of the permit review process.

(17)

Substantial damage determination. Perform an assessment of damage from any origin to the structure using FEMA's residential substantial damage estimator (RSDE) software to determine if the damage equals or exceeds fifty percent of the market value of the structure before the damage occurred.

(18)

Substantial improvement determination. Perform an assessment of permit applications for improvements or repairs to be made to a building or structure that equals or exceeds fifty percent of the market value of the structure before the start of construction. Cost of work counted for determining if and when substantial improvement to a structure occurs shall be cumulative for a period of five years. If the improvement project is conducted in phases, the total of all costs associated with each phase, beginning with the issuance of the first permit, shall be utilized to determine whether "substantial improvement" will occur.

The market values shall be determined by one of the following methods:

a.

The current assessed building value as determined by the county's assessor's office or the value of an appraisal performed by a licensed appraiser at the expense of the owner within the past six months.

b.

One or more certified appraisals from a registered professional licensed appraiser in accordance with the laws of South Carolina. The appraisal shall indicate actual replacement value of the building or structure in its pre-improvement condition, less the cost of site improvements and depreciation for functionality and obsolescence.
