give them the meaning they have in common usage and to give this ordinance its most reasonable application.
"Area of special flood hazard"- means the land in the floodplain within a community subject to a one
percent or greater chance of flooding in any given year.
"Base flood"- means a flood which has a one percent chance of being equaled or exceeded in any given
year (also called the "100-year flood"). Base flood is the term used throughout this ordinance.
"Building"- see "Structure".
"Development" means any man-made change to improved or unimproved real estate, including but not
limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations
• or storage of equipment or materials.
"Flood or Flooding" means:
1. A general and temporary condition of partial or complete inundation of normally dry land areas from:
the overflow of inland or tidal waters; the unusual and rapid accumulation or runoff of surface waters from any
source; or mudslides (i.e., mudflows) which are proximately caused by flooding as defined herein and are akin
to a river of liquid & flowing mud on the surface of normally dry land areas, as when earth is carried by a
current of water & deposited along the path of the current.
2. The collapse or subsidence of land along the shore of a lake or other body of water as a result of
erosion or undermining caused by waves or currents of water exceeding anticipated cyclical levels or suddenly
caused by an unusual and unforeseeable event which results in flooding as defined in this definition.

source - see "Flooding".
"Floodplain Administrator" is the individual appointed to administer and enforce the floodplain
management regulations.
"Floodplain management" means the operation of an overall program of corrective and preventive
measures for reducing flood damage and preserving and enhancing, where possible, natural resources in the
floodplain, including but not limited to emergency preparedness plans, flood control works, floodplain
management regulations, and open space plans.
"Floodplain management regulations" means this ordinance and other zoning ordinances, subdivision
regulations, building codes, health regulations, special purpose ordinances (such as grading and erosion control)
and other application of police power which control development in flood-prone areas. This term describes
federal, state or local regulations in any combination thereof which provide standards for preventing and
reducing flood loss and damage.

Interior or directly by the Secretary of the Interior in states with approved programs.

required utilities. The term "manufactured home" does not include a "recreational vehicle"

"Start of construction" includes substantial improvement and other proposed new development and
means the date the building permit was issued, provided the actual start of construction, repair, reconstruction,
rehabilitation, addition, placement, or other improvement was within 180 days from the date of the permit. The
actual start means either the first placement of permanent construction of a structure on a site, such as the
pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of
excavation; or placement of a manufacture home on a foundation. Permanent construction does not include
land preparation, such as clearing, grading, and filling; nor does it include the installation of streets and/or
walkways; nor does it include excavation for a basement, footings, piers, or foundations or the erection of
temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or

development of a structure, the cost of which equals or exceeds 50 percent of the marked value of the structure

• c. With electrical heating, ventilation, plumbing and air conditioning equipment and other service facilities
that are designed and/or located so as to prevent water from entering or accumulating within the components

proposal or other proposed new development, including manufactured home parks or subdivisions, is in a flood-
prone area, any such proposals shall be reviewed to assure that:
