Dana Point City Zoning Code

CHAPTER 9

31 FLOODPLAIN OVERLAY DISTRICT

§ 9.31.010 Intent and Purpose.

The three Floodplain Overlay (FP) districts protect the public health, safety, and general welfare from flood hazards by assuring proper use and development.
The FP-1 district is applied to areas shown as "floodway" areas on the FEMA Flood Insurance Rate Map (FIRM), as "floodway" on the other areas in which the City has determined that a floodway exists.
The FP-2 district is applied to "areas inundated by 100 year flood" which are shown as "A," "A1" through "A30," "AO," "AH," "A99," and "M" on FEMA Flood Insurance Rate Maps and areas in which the City has determined to be a special flood hazard area.
The FP-3 district is applied to coastal areas subject to wave action, which are specifically shown as "AE," "E," "VE," "V," and "V1" through "V30" on the FEMA Flood Insurance Rate Maps and areas in which the City has determined to be a coastal high hazard area.
The Floodplain Overlay districts are overlay districts which may be combined with any other zoning district. The floodplain overlay districts provide use, development, and permit requirements that are applied in addition to the underlying zoning district and the requirements of other overlay districts. In the event of conflicting provisions between the underlying district and the overlay districts, the more restrictive requirements shall prevail.
The purposes of the Floodplain Overlay Districts include:
(a) 
The Floodplain Overlay districts and the flood hazard areas of the City of Dana Point are subject to periodic inundation which may result in loss of life 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.
(b) 
These flood losses are caused by the cumulative effect of obstructions in areas of special flood hazards which increase flood heights and velocities and when inadequately floodproofed, elevated, or otherwise protected from flood damage also contribute to the flood loss.
(c) 
It is the purpose of this Chapter to promote the public health, safety, and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed:
(1) 
To protect human life and health;
(2) 
To minimize expenditure of public money for costly flood control projects;
(3) 
To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;
(4) 
To minimize prolonged business interruptions;
(5) 
To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone, and sewer lines, streets and bridges located in areas of special flood hazard;
(6) 
To help maintain a stable tax base by providing for the second use and development of areas of special flood hazard so as to minimize future flood blight areas;
(7) 
To ensure that potential buyers are notified that property is in an area of special flood hazard; and
(8) 
To ensure that those who occupy the areas of special flood hazard assume responsibility for their actions on the property.
(d) 
In order to accomplish its purposes, this Chapter includes methods and provisions for:
(1) 
Restricting or prohibiting uses within the Floodplain Overlay Districts which are dangerous to health, safety, and property due to water or erosion hazards or which result in damaging increases in erosion or flood heights or velocities;
(2) 
Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;
(3) 
Controlling the alteration of natural floodplains, stream channels, and natural protective barriers, which help accommodate or channel flood waters;
(4) 
Controlling filling, grading, dredging, and other development which may increase flood damage; and,
(5) 
Preventing or regulating the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards in other areas.
(Added by Ord. 93-16, 11/23/93)

§ 9.31.020 General Provisions.

(a) 
Lands to Which this Chapter Applies. This Chapter shall apply to all areas of special flood hazards, areas of flood-related erosion hazards, and areas of mudslide (i.e., mudflow) hazards within the jurisdiction of the City of Dana Point.
(b) 
Basis for Establishing the Areas of Special Flood Hazard. The areas of special flood hazards, areas of flood-related erosion hazards, and areas of mudslide (i.e., mudflow) hazards identified by the Federal Emergency Management Agency (FEMA) or the Federal Insurance Administration in a scientific and engineering report entitled "Flood Insurance Study" for Orange County, California, and incorporated areas dated September 15, 1989, and February 5, 1992, with accompanying Flood Insurance Rate Map (FIRM) and all subsequent revisions are hereby adopted by reference and incorporated in this Chapter. This Flood Insurance Study is on file at the City of Dana Point. This Flood Insurance Study is the minimum area of applicability of this Chapter and may be supplemented by studies for other areas which allow implementation of this Chapter and which are recommended to the City Council by the Floodplain Administrator.
(c) 
Compliance. No structure or land shall be constructed, located, extended, converted, or altered without full compliance with the terms of this Chapter and other applicable regulations. Violation of the provisions of this Chapter by failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with conditions) shall constitute a misdemeanor. Nothing herein shall prevent the City Council from taking such lawful action as is necessary to prevent or remedy any violation.
(d) 
Abrogation and Greater Restrictions. This Chapter is not intended to repeal, abrogate, or impair any existing easements, covenants or deed restrictions. However, where this Chapter and another Ordinance, easement, covenant, or deed restriction conflict or overlap, whichever imposes the more stringent restrictions shall prevail.
(e) 
Interpretation. In the interpretation and application of this Chapter, all provisions shall be:
(1) 
Considered as minimum requirements;
(2) 
Liberally construed in favor of the governing body; and
(3) 
Deemed neither to limit nor repeal any other powers granted under State Law.
(f) 
Warning and Disclaimer of Liability. The degree of flood protection required by this Chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur on rare occasions. Flood heights may be increased by man-made or natural causes. This Chapter does not imply that land outside the areas of special flood hazards, areas of flood-rated erosion hazards, and areas of mudslide (i.e., mudflow) hazards, or uses permitted within such areas will be free from flooding or flood damages. This Chapter shall not create liability on the part of the City of Dana Point, any officer or employee thereof, for any flood damages that result from reliance on this Chapter or any administrative decision lawfully made thereunder.

(4) 
Generally, exemptions may be issued for new constructions and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, provided Sections 9.31.070(a)(3)(A) through 9.31.070(a)(3)(K) have been fully covered. As the lot size increases beyond one-half acre, the technical justification required for issuing the exemption increases.
(5) 
Upon consideration of the factors of Section 9.31.070(a)(3) and the purposes of this Chapter, the City Council may attach such conditions to the granting of exemptions as it deems necessary to further the purposes of this Chapter.
(6) 
The Director of Community Development shall maintain the records of all appeal actions and report any exemptions to the Federal Insurance Administration upon request.
(b) 
Conditions for Exemption.
(1) 
Exemptions may be issued for the reconstruction, rehabilitation, or restoration of structures listed in the National Register of Historic Places or the State Inventory of Historic Places, without regard to other conditions set forth herein.
(2) 
Exemptions shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.
(3) 
Exemptions shall only be issued upon a determination that the exemption is the minimum necessary, considering the flood hazard, to afford relief.
(4) 
Exemptions shall only be issued if the Zoning Map includes property within a Floodplain Overlay District of that property does not meet the purpose and intent for that district. The determination to exempt a property shall be based on a study of topographic and design flood elevation contours on the subject property and on such additional information as he finds necessary or appropriate.
(5) 
Exemptions shall only be issued if flood protection or floodproofing work adequate to protect against the design flood, and in compliance with City and other applicable flood control and flood protection standards and policies, has been completed. The finding of exemption shall confirm that any stream, channel, storm drain, or landfill improvements fully offset flood surface elevations established by the applicable map and that, if the property is included on a Flood Insurance Rate Map or a Flood Boundary and Floodway Map, all such flood protection or flood control work has been approved by the appropriate Federal agency and the property removed from the floodplain designation on such maps.
(6) 
Exemptions shall only be issued upon:
(A) 
A showing of good and sufficient cause;
(B) 
A determination that failure to grant the exemption would result in exceptional hardship to the applicant; and
(C) 
A determination that the granting of an exemption will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public or conflict with existing local laws or ordinances.
(7) 
Exemptions may be issued for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use provided that the provisions of Sections 9.31.070(b)(1) through 9.31.070(b)(4) are satisfied and that the structure or other development is protected by methods that minimize flood damage during the base flood and create no additional threats to public safety.

Any applicant to whom an exemption is granted shall be given written notice that the structure will be permitted to be built with a lowest floor elevation below the regulatory flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation. A copy of the notice shall be recorded by the Floodplain Board in the Office of the County of Orange County Recorder and shall be recorded in a manner so that it appears in the chain of title of the affected parcel of land.
