18.65.030 “FP” Floodplain Overlay Zoning District.
(A) Purpose. The purpose of this “FP” Floodplain Overlay Zoning District is to promote the public health, safety, and general welfare, and to minimize both public and private losses due to flood conditions by recognizing the impacts and hazards associated with flood conditions. It is the intent of this overlay to promote the public health and safety by minimizing the exposure of structures to potential flooding by encouraging future development to be located outside of the floodway and that appropriate uses and construction methods be utilized within the areas of the floodplain.
(B) General Provisions – “FP” Overlay Zoning District.
(1) This overlay district shall apply to all areas, within the jurisdictional boundaries of the City, that are designated as special flood hazard areas (SFHA) by the “Flood Insurance Study for Yuma County, Arizona (FIS),” dated December 15, 1983, and/or identified by FEMA in the specific Flood Insurance Rate Maps (FIRM), for those lands within the jurisdictional boundaries of the City of San Luis. The special flood hazard areas (SFHA) along with the FIRM are the minimum areas of applicability of this overlay zoning and may be supplemented by studies, amendments, and revisions. A set of FIRM maps shall be retained by the City and shall be available for inspection.
(2) If the Colorado River levee system is certified within two years from the date of adoption of the ordinance codified in this title, and continues to remain certified, then those areas protected by the levee system may be removed from the floodplain regulations.
(3) The Yuma County Floodplain Administrator and the Yuma County Flood Control District shall have regulatory powers over those lands identified as SFHA and delineated in the FIRM for the City.
(4) No structure or land shall hereafter be constructed, located, extended, converted or altered without full compliance with the terms outlined in the FIS for Yuma County, those of this overlay district and other applicable regulations.
(5) The degree of flood protection required by the “FP” Overlay Zoning District is considered minimum for regulatory purposes and is based on scientific and engineering considerations of the Yuma County Flood Control District. Larger floods can and will occur on rare occasions. Flood heights may be increased by manmade or natural causes. The “FP” Overlay Zoning District 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. This overlay district shall not create liability on the part of the City or any officer or employee thereof, or the Yuma County Flood Control District for any flood damages that result from reliance on this overlay district or any administrative decision lawfully made herein.
(C) Permitted Uses – “FP” Overlay Zoning District.
(1) Those uses permitted by right in the “OSC” and “OSR” Zoning Districts.
(2) Those uses permitted by right in the “RA-10” Zoning District, except for kennels for the boarding or lodging, breeding, or training of small domesticated animals.
(D) Conditional Uses – “FP” Overlay Zoning District. Those uses permitted as conditional uses in the “RA-10” Zoning District, except that the following uses shall not be permitted:
(1) Kennels for the boarding or lodging, breeding, or training of small domesticated animals; and
(2) Cemeteries, crematoriums, columbaria and mausoleums including associated on-site mortuary.
(E) Development Regulations – “FP” Overlay Zoning District.
(1) In all areas of special flood hazard all new construction and substantial improvements shall be anchored to prevent floatation, collapse or lateral movement of the structure and capable of resisting the hydrostatic and hydrodynamic loads.
(2) All new construction and substantial improvements shall be constructed using materials and utility equipment resistant to flood damage and with methods and practices that minimize flood damage.
(3) All new construction and substantial improvements shall be designed and constructed so as to prevent water from entering or accumulating within any and all service, mechanical, or utility equipment components of the structure during conditions of flooding.
(4) All subdivision proposals shall have adequate drainage and shall be designed to direct flood waters around and away from proposed structures. All lots shall have a building pad that is certified to be one foot above the level of the base flood elevation. (Ord. 312 § 2(13.2), passed 4-11-2012. Code 2012 § 152.197.)
