Prevention

After the floods in 2002 and 2006 the strategic approach,

based on flood protection concepts has become operational

on Saxon level. Its relevance and importance was under

scrutiny during the floods in 2010, 2011, 2012 and 2013.

All implemented preventive measures worked according to the

strategic settings.

EPRI nationale 2011

Context

French territories are not adapted to flood

« Vendéennes style» houses in la Faute sur mer – Xynthia

Storm Dordrecht

Mainz Context

Insufficient protection

Context

In financial terms : a national frame based on two major axis

Insurance Protection = 90% of flood risk management policy

Increasing costs No national strategy

Administrative complexity

Repairs of dikes

Role of local authorities

Local authorities finance

2/3 of this axis

A decreasing involvement of

State…

In legal terms : National level defines rules and responsabilities

Local level : operationnal level

What are the responsabilities ? Mayor is responsible for people safety in case of local flood

Local representative of State is responsible for people safety in case of wide scale flood

National level gives legal tools to the municipalities

But, in parallel to the municipalities, different types of other local authorities may undertake, under their own responsability, actions for flood risk management

Role of local authorities

Diversity of local authorities in France

22 regions

No legal hierarchy between the different levels

100 « départements »

2500 « intercommunalités »

36 000 municipalities

Several hundred of River basin management Authorities

Actions of Municipalities

Crisis management People awareness

Elaboration of legal document of Land management

Maintenance of dikes

Major

difficulties

Lack of human

capacities to

implement legal

obligations

Actions of « Intercommunalités »

Helping municipalities in respecting their legal obligations (technical terms)

Innovative urban regeneration

Maintenance of

dikes(sometimes)

Major

difficulties

Lack of

knowledge and

political

willingness

Elaboration of activity continuity plans for their public services exposed to flood risk

Implementation of action for the reduction of vulnerability of houses

Actions of « départements »

Actions of « régions »

Maintenance of dikes (financial action)

Major

difficulties

Lack of

knowledge and

political

willingness

Reduction of vulnerability of compagnies

Actions of « river basin Authorities »

Helping municipalities in respecting their legal obligations (financial and technical terms)

Implementation of structural measures

Major difficulties

Lack of financial

capacities and of

strong political

position

Reduction of vulnerability

A general schema

But in fact a very important diversity of cases

No national rules to define precisely actions of local authorities at the different level (except for municipalities)

But an essential action to face the decreasing involvement of state

An important challenge for governance With the progressive decentralization, and the implemenation of the

flood directive, local authorities becomes the major stakeholders for the risk management (2/3 of fundings)

But …

…a very high complexity

…an expensive cost

… a real difficulty to make a good articulation between the different scales of local authorities

A new law of decentralization « Acte III » : a solution to precise « who does what » in

the future ?

Are we creating safe and sustainable communities?
