Statutory authorization. The Legislature of the State of Florida has authorized and delegated in F.S. ch. 125, the responsibility of local government units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. Therefore, the Board of County Commissioners of Collier County does hereby adopt the follow- ing Floodplain management regulations. (Ord. No. 2019-01, § 1) Sec. 62-27. Findings of fact. (1) The Flood hazard areas of Collier County are subject to periodic inundation from intense rain storms and/or tropical cyclone storm surge, which could result in loss of life and property, health and safety hazards, disruption of com- merce and governmental services, extraordinary public expenditures for Flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety and general welfare. (2) These Flood losses are caused by the cumulative effect of obstructions in Floodplains causing increases in Flood heights and veloci- ties, and by the occupancy in Flood hazard areas by uses vulnerable to Floods or hazardous to other lands which are inadequately elevated, Floodproofed or otherwise unprotected from Flood damages. (Ord. No. 2019-01, § 1) Sec. 62-28. Statement of purpose. It is the purpose of this Ordinance to save lives, promote the public life health, safety and general welfare and minimize public and private losses due to Flood conditions in specific areas by provisions designed to: (1) Restrict or prohibit uses which are danger- ous to health, safety and property due to water or erosion hazards, which result in damaging increases in erosion or in Flood heights and velocities; (2) Require that uses vulnerable to Floods including facilities which serve such uses be protected against Flood damage throughout their intended life span; (3) Control the alteration of natural Floodplains, stream channels, and natural protective barriers which are involved in the accommodation of Floodwaters; (4) Control filling, grading, dredging and other Development which may increase erosion or 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. (Ord. No. 2019-01, § 1) Sec. 62-29. Objectives. The objectives of this Ordinance are to: (1) Protect human life, health and to eliminate or minimize property damage; (2) Minimize expenditure of public money for costly Flood control projects; *Editor’s note—Ord. No. 98-1, adopted Jan. 6, 1998, set out provisions regulating the conversion of swales to culverts in the public rights-of-way within an area of Naples Park. This material has been included as §§ 110-41—110-52 to read as herein set out at the discretion of the editor. Former § 62-1 provided for a moratorium which expired on Jan. 1, 1997 relating to the same matter. See the Code Comparative Table. †Editor’s note—Ord. No. 2019-01, §§ 1—19, adopted Jan. 8, 2019, repealed the former Art. II, §§ 62-26—62-161, and enacted a new Art. II as set out herein. The former Art. II was entitled "Flood Damage Prevention,"and derived from: Ord. No. 86-28, §§ 1—21; Ord. No. 87-80, § 1—21; Ord. No. 90-31, §§ 1—5; Ord. No. 2005-51, §§ 1, 2; and Ord. No. 2010-36, §§ 1, 2; Ord.

A.Title.These regulations shall be known as the Floodplain Management Ordinance of Col- lier County, Florida. B.Scope.The provisions of this ordinance shall apply to all development that is wholly within or partially within any flood hazard area, including but not limited to, the subdivision of land; filling, grading, and other site improve- ments and utility installations; construction, alteration, remodeling, enlargement, improve- ment, replacement, repair, relocation or demoli- tion of buildings, structures, and facilities that are exempt from the Florida Building Code; placement, installation, or replacement of manufactured homes and manufactured build- ings; installation or replacement of tanks; place- ment of recreational vehicles; installation of swimming pools; and any other development. This ordinance shall also apply to establishing minimumfloorelevationsforbuildingsconstructed within areas identified as Zone X and X-500 on the Flood Insurance Rate Maps adopted in Sec- tion 4, C (§ 62-72.C) of this ordinance. C.Intent.The purposes of this ordinance and the flood load and flood-resistant construction requirements of the Florida Building Code are to establish minimum requirements to safeguard the public health, safety, and general welfare and to minimize public and private losses due to flooding through regulation of development in flood hazard areas to: (1) Minimize unnecessary disruption of com- merce, access and public service during times of flooding; (2) Require the use of appropriate construc- tion practices in order to prevent or minimize future flood damage; (3) Manage filling, grading, dredging, mining, paving, excavation, drilling operations, storage of equipment or materials, and other development which may increase flood damage or erosion potential; (4) Manage the alteration of flood hazard areas, watercourses, and shorelines to minimize the impact of development on the natural and beneficial functions of the floodplain; (5) Minimize damage to public and private facilities and utilities; (6) Help maintain a stable tax base by provid- ing for the sound use and development of flood hazard areas; (7) Minimize the need for future expenditure of public funds for flood control projects and response to and recovery from flood events; and (8) Meet the requirements of the National Flood Insurance Program for community participation as set forth in Title 44 Code of Federal Regulations, Section 59.22. D.Coordination with the Florida Building Code.This ordinance is intended to be administered and enforced in conjunction with the Florida Building Code. Where cited, ASCE 24 refers to the edition of the standard that is referenced by the Florida Building Code. E.Warning.The degree of flood protection required by this ordinance and the Florida Build- ing Code, as amended by this community, is considered the minimum reasonable for regula- tory 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. This ordinance does not imply that land outside of mapped special flood hazard areas, or that uses permit- ted within such flood hazard areas, will be free from flooding or flood damage. The flood hazard areas and base flood elevations contained in the Flood Insurance Study and shown on Flood Insurance Rate Maps and the requirements of Title 44 Code of Federal Regulations, Sections 59 and 60 may be revised by the Federal Emergency Management Agency, requiring this community to revise these regulations to remain eligible for participation in the National Flood Insurance § 62-53 COLLIER COUNTY CODE CD62:10Supp. No. 103 Program. No guaranty of vested use, existing use, or future use is implied or expressed by compliance with this ordinance. F. Disclaimer of Liability. This ordinance shall not create liability on the part of the Board of County Commissioners of Collier County, Florida or by any officer or employee thereof for any flood damage that results from reliance on this ordinance or any administrative decision law- fully made thereunder. (Ord. No. 2019-01, § 3) Sec. 62-72. Applicability. A. General. Where there is a conflict between a general requirement and a specific require- ment, the specific requirement shall be applicable. B. Areas to Which This Ordinance Applies. This ordinance shall apply to all flood hazard areas within the unincorporated Collier County, as established in Section 4, C (§ 62-72.C) of this ordinance. Additionally, the requirements for establishing minimum floor elevations shall be applicable for all areas identified as Zone X and X-500. C. Basis for Establishing Flood Hazard Areas.
