	Floodplain - Wikipedia, the free encyclopedia
		Floodplains are formed by the deposition of sediment carried by river as it floods.
		Still, floodplains are most commonly found near the mouth of a large river, such as the Rhine, the Nile, or the Mississippi, where there are occasional floods and the river usually carries a large amount of sediment.
		The floodplain during its formation is marked by meandering or anastomosing streams, ox-bow lakes and bayous, marshes or stagnant pools, and is occasionally completely covered with water.

	Community Involvement in Flood and Floodplain Management
		However, Australian floodplain management practice is largely directed towards alleviating the damage potential of existing development at risk of flooding and to ensure that there is no growth in the potential for loss due to development inappropriately sited on flood-liable lands.
		The Flood Authority is responsible for undertaking and supervising flood studies, for the preparation of flood maps, and for the delineation of floodway and flood fringe zones.
		However, on a state-wide basis, floodplain management was characterized at the municipal level by a lack of standards and a lack of coordinated programmes.

	City of Austin - Floodplain Development Information for Developers and Engineers
		Projects proposing development in the 25-year and 100-year floodplains have the potential for placing our citizens and their property at risk of flooding and producing changes in floodplain elevations and plan view extent.
		Excavation and fill of the floodplain and modification of the channel are subject to requirements to preserve the natural and traditional character of the land and waterway.
		Floodplain mapping that is outdated may create unnecessary encumbrances (such as federal requirements for flood insurance or building permit restrictions), or may allow citizens to be placed at undue risk of flooding.

	What Is A Floodplain?
		By their very nature, floodplains are the low, flat, periodically flooded lands adjacent to rivers, lakes and oceans and subject to geomorphic (land-shaping) and hydrologic (water flow) processes.
		As distinguished from the floodplain, a river' floodway is the dry zone typically between levees, which is designed to convey flood waters (making wonderful areas for bike trails and parkways because it is only periodically flooded).
		For land use planning purposes, the regulatory floodplain is usually viewed as all lands within reach of a 100 year flood.

		The flood-fringe is the portion of the floodplain outside of the floodway, which is covered by floodwater during the 100-year discharge.
		It is also that part of the floodplain wherein development is subject to a community's floodplain ordinance.
		Floodplain management means the operation of an overall program of corrective and preventive measures for reducing flood damage, including but not limited to emergency preparedness plans, flood control works and floodplain management regulations.

		Floodplain delineation involves the development of detailed topographic maps to determine where water goes, while incorporating the results of rainfall-runoff relationship studies to determine peak flood discharges and depths.
		The delineation studies are used by the District to better manage the floodplain, to reduce or prevent flood damage, and to maintain the natural and beneficial functions of the floodplains.
		Floodplain representatives are on hand at the District to help residents determine whether or not their property is in a flood hazard area and to provide information.

	WDFW - An Evaluation of Fish and Amphibian Use of Restored and Natural Floodplain Wetlands
		In floodplains, restoration projects with water control structures are often intended to conserve and restore wetland habitat characteristics including floodplain function, hydrologic connectivity, and critical habitat for migratory wildlife and threatened and endangered semi-aquatic and aquatic wildlife and plant species.
		In Carnation Creek watershed (a drainage in Vancouver, B.C.), a floodplain area of about 50 hectares in a given location, 15-25% of the total smolt yield were captured in off-channel sites, and most of those fish spent the winter in off-channels devoid of standing water during summer (Brown and Hartman 1988).
		The Chehalis River floodplain has seasonal wetlands that have infrequent surface water connections to the river, are temporarily flooded for brief periods, and are primarily rain-fed.

	Shoreland management guide - Floodplain management: Minnesota DNR
		Under state law, the floodplain is considered to be the land adjoining lakes and rivers that is covered by the "100-year" or "regional" flood.
		Under the statewide floodplain management standards, local communities cannot allow development in the floodplain that would cumulatively cause more than a 1/2 foot (6 inches) increase in the height of the 100-year flood.

		The State of Michigan’s Floodplain Regulatory Authority, found in Part 31, Water Resources Protection, of the Natural Resources and Environmental Protection Act (NREPA), 1994 PA 451, as amended, requires that a permit be obtained prior to any alteration or occupation of the 100-year floodplain of a river, stream or drain.
		The floodplain is divided into two parts, the floodway which carries most of the flow during a flood event, and the floodway fringe which is an area of very slow moving water or “slack water”.
		Floodways are the channel of a river or stream and those portions of the floodplain adjoining the channel which are reasonably required to carry and discharge the 100 year flood; these are high hazard areas of rapidly moving water during times of flood.

	EWP Floodplain Easement Facts \| NRCS
		Floodplain easements restore, protect, maintain, and enhance the functions of the floodplain; conserve natural values including fish and wildlife habitat, water quality, flood water retention, ground water recharge, and open space; reduce long-term federal disaster assistance; and safeguard lives and property from floods, drought, and the products of erosion.
		Under the floodplain easement option, a landowner voluntarily offers to sell to the NRCS a permanent conservation easement that provides the NRCS with the full authority to restore and enhance the floodplain’s functions and values.
		To the extent practicable, NRCS actively restores the natural features and characteristics of the floodplain through re-creating the topographic diversity, increasing the duration of inundation and saturation, and providing for the re-establishment of native vegetation.

	Floodplain Management
		For regulatory purposes, the floodplain is divided into two areas based on water velocity: the floodway and the flood fringe.
		Due to the high degree of hazard, most floodplain regulations require that proposed floodway developments do not block the free flow of flood water as this could dangerously increase that water's depth and velocity.
		Therefore, floodplain regulations for the flood fringe typically allow development to occur but require protection from the flood waters through the elevation of the buildings above the 100-year flood level, floodproofing buildings so that water cannot enter the structure and watershed improvements to assure overall flood elevation does not increase.

		The purpose of Executive Order 11988 - Floodplain Management is "to avoid to the extent possible the long and short term adverse impacts associated with the occupancy and modification of floodplains and to avoid direct or indirect support of floodplain development wherever there is a practicable alternative."
		The floodplain designated by FEMA as the Special Flood Hazard Area (SFHA) is represented on the flood map by darkly shaded areas designated with the letter "A" or "V." FEMA uses engineering studies to determine the delineation of these areas or zones subject to flooding.
		The critical action standard applies to the proposed use of HUD assistance to structures or facilities located within the 500-year floodplain, when the structures or facilities are likely to contain occupants who may not be sufficiently mobile to avoid loss of life or injury during flood or storm events.
