Reduction of Flood Losses
Containing the Problem.
COMMUNITY INVOLVEMENT IN FLOOD
AND FLOODPLAIN MANAGEMENT
Integrated floodplain management involves a
range of technical, policy and implementation
It requires an effective partnership between all
levels of government, the private sector and the
ROLE OF GOVERNMENT
The three tiers of Government
involved in floodplain management :-
Local Government has prime responsibility for
State Government has the principal responsibility
for land and water resources management;
Federal Government assumes a supervisory role
and grants financial assistance.
DEVELOPMENT OF FLOODPLAIN
Structural Works Phase
• Flood protection relied almost entirely on structural
• Importance of land-use planning to control growth in
damages was realised.
Flood Emergency Management Phase
• Recognition of emergency planning as a component of
Integrated Planning Phase
• Pro-active approach incorporating resource
management and sustainable development concepts.
INTEGRATION OF FLOODPLAIN
INTEGRATED FLOODPLAIN MANAGEMENT
RECOGNISES THREE DISTINCT PROBLEMS
ASSOCIATED WITH DEVELOPMENT ON FLOOD-
Existing problem which relates to current
Future problem which relates to development
yet to occur;
Residual problem which relates to the
occurrence of floods which exceed existing
THIS APPROACH REQUIRES THE INTEGRATION OF:-
INDIVIDUAL FLOODPLAIN MANAGEMENT MEASURES.
ROLES AND RESPONSIBILITIES OF THE STAKEHOLDERS.
FLOODPLAIN MANAGEMENT AND FLOOD EMERGENCY
RESOURCE MANAGEMENT CONSIDERATIONS AND
STORMWATER AND MAINSTREAM FLOODING EFFECTS.
ADOPTION OF AN INTEGRATED CATCHMENT
MANAGEMENT APPROACH TO FLOODING.
NEW SOUTH WALES FLOODPLAIN
This system was upgraded in January, 2001
with the release of a revised floodplain
The manual aims to foster the wise, rational
and sustainable use of flood prone land by:-
• reducing the social and financial cost resulting from the
risks of occupying the floodplain;
• increasing the sustainable social, economic and ecological
benefits of using the floodplain;
• improving or maintaining the diversity and well-being of
riverine and floodplain ecosystems.

NEW SOUTH WALES FLOODPLAIN
Community participation is encouraged under
Representatives of the public, particularly
owners of flood liable land, are actively involved
in the preparation and review of floodplain
Management plans are exhibited and public
comment is considered before plan is finalised
State Governments have the primary responsibility
for the management of land, water and the
Responsibility for floodplain management is
fragmented across many pieces of legislation;
In New South Wales, more than 40 separate Acts
relate to water management alone;
Several important and powerful Acts apply for
floodplain management purposes.
The more important of the available Acts are:-
Water Supplies Authorities Act, 1987
provides for the establishment of flood mitigation
authorities to ensure effective local government
involvement in integrated catchment management.
Catchment Management Act, 1989
this Act encourages the the application of
integrated management principles to the
management of land, water, vegetation and other
natural resources of the State’s catchments. There
is no provision for the formal implementation of
plans formulated under this Act.
Environmental Planning and Assessment Act, 1979
under this Act local government councils are required
to prepare and publish plans relating to zoning and
development standards. These plans must be
preceded by a detailed environmental study. Draft
plans are prepared in consultation with other
authorities and made available for public display and
comment before adoption.
Local Government Act, 1993
this Act requires local councils to properly manage
and conserve the environment under their control. It
allows councils to prepare orders for the control of
Water Act, 1912
this Act controls earthworks constructed on floodplains
which have been designated as floodplain areas.
Works include levees and related structures in rural
areas. The work is refused if it is likely to affect the
distribution of flood flows.
Soil Conservation Act, 1938
this Act is primarily concerned with the management of
soil conservation. It extends to the preparation of plans
for surface drainage and sub-catchment management
plans. It is not widely used for flood mitigation
Aspects of floodplain management which
require direct involvement and cooperation
of the floodplain community are:-
identification of the flood problem;
formulation and analyses of potential flood mitigation
implementation of long-term management strategies;
flood awareness and response.
Effective community consultation requires
consideration of the following aspects:-
informing the community of the need to undertake a
floodplain management study and its purpose;
assessing the community’s level of concern, knowledge and
understanding in relation to flood issues and flood readiness;
obtaining information community members may have relating to
historic flood levels, behaviour, etc.
assessing community aspirations in relation to floods;
providing the community with information on alternative
floodplain management measures;
providing a mechanism for the community to have an input
into the selection of appropriate measures.
FLOODPLAIN MANAGEMENT COMMITTEE
Membership of the committee i s a balanced mix of elected,
administrative, community representatives and technical
The principle objective of the management committee is to assist
the flood authority in the development and implementation of
the floodplain management plan.
Community representatives include people from affected
residential and business areas.
The committee is responsible for supervising the preparation
of reports covering:-
• data collection;
• flood study;
• floodplain risk management study;
• floodplain risk management plan;
• implementation of plan.
Public participation in the collection and collation of
flood data can provide useful data as input to a flood
Information collected includes flood heights, areas of
rural lands inundated and the urban areas and
facilities affected by floodwaters;
Information collected is useful for calibrating and
verifying flood models and describing flood
FLOOD AWARENESS AND RESPONSE
A typical flood emergency plan includes the
the nature of the flood threat;
areas affected by flooding;
sources of flood intelligence;
roles and responsibilities of involved agencies;
trigger conditions for plan activation;
liaison and communications arrangements.
COMMUNITY EDUCATION AND
Floodplain management plans include regular
education programmes which create community
readiness to cope with flooding.
The tools employed include:-
• community events;
• schools programmes;
• radio and television;
• brochures and action guides;
• flood action cards;
• commemoration of well remembered floods.
Effective integrated floodplain management
requires the full support of the catchment
Support can only be achieved by the involvement
and participation of the floodplain community from
the initial planning phase to the implementation
Community education, community involvement and
acceptance ,community ownership and
responsibility for flooding problems are
prerequisites for the satisfactory solution of such
The need for effective community participation in the
floodplain management process cannot be over
