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.
