Full Breakdown
Chapter 34 of the county code, adopted March 3, 2015 and amended April 18, 2023, governs development within areas of special flood hazard in the unincorporated areas of Effingham County (Sec. 34-6). Sec. 34-8 requires a development permit before any development activity begins in a flood hazard area, applied for through the planning and engineering department under Sec. 34-47, which must show elevations, structure dimensions, fill placement, and drainage facilities. Sec. 34-9 bars locating, extending, converting, or altering any structure or land without full compliance.
The general standards in Sec. 34-81 require new construction and substantial improvements to be anchored against flotation, collapse, or lateral movement; built with materials and utility equipment resistant to flood damage; and constructed by methods that minimize flood damage. Enclosed areas below the lowest floor must be flood-resistant and equalize hydrostatic forces through openings sized at one square inch per square foot of enclosed area, with the bottom of openings no higher than one foot above grade. Manufactured homes must be anchored against flotation and lateral movement consistent with state wind-resistance rules, and new water, sewer, and on-site waste systems must be designed to prevent floodwater infiltration or contamination.
The county engineer, designated administrator under Sec. 34-46, reviews permits for compliance and can require certification from a registered professional engineer or architect. Sec. 34-13 makes a violation of the chapter a misdemeanor punishable under Sec. 1-19 of the county code, with each day of continuing violation a separate offense, in addition to any other lawful county action.
Violations & Fines
Sec. 34-13 makes failure to comply with Chapter 34, including its permit and construction standards, a misdemeanor punishable under Sec. 1-19 of the Code of Effingham County, with each day of continued violation charged as a separate offense, plus payment of all costs and expenses of the case; the county may also pursue other lawful remedies to prevent or correct the violation.
