Oxfordshire Local Flood Risk Management Strategy

A strategy document for dealing with flood risk management in Oxfordshire

Following the significant floods in 2007, the Government gave local authorities new powers to help manage local flood risk in a more coordinated way.

The Flood Water Management Act 2010 requires county councils to lead the coordination of flood risk management for surface water, groundwater and smaller watercourses in their area.  Main river flooding remains the responsibility of the Environment Agency.

Oxfordshire County Council has now produced a local flood risk management strategy and an action plan.  This provides a clear vision about how flood risk will be dealt with in Oxfordshire.

Flood investigation Thresholds

As the Lead Local Flood Authority (LLFA) for Oxfordshire, one of the Council’s duties is to investigate flood events that occur within in its area as it deems necessary.

Upon learning of a flood event within Oxfordshire, the Council will consider whether an investigation should be carried out, under Section 19 of the Flood and Water Management Act (2010), in order to determine:

  • which authorities and individuals have relevant flood risk management functions
  • whether each of those authorities or individuals have exercised, or are proposing to exercise, those functions in response to the flood

Adopted Flood Investigation Protocol

The investigating officer will use the following guidance to determine whether an investigation should be carried out. This will be based on the assessment of the consequences of flooding that are considered to be sufficiently serious in terms of risk to loss of life, residential & commercial property, critical infrastructure, transport, cultural sites and environmental sites.

The Council's thresholds for formal investigation of residential and commercial properties are as follows. A formal flood investigation will be carried out if one or more of the following occurs:

Criteria for flood investigation: 

  • Internal flooding (excluding to basements) to five or more residential properties or businesses within an area of 1km2
  • Internal flooding of a business premises employing more than 10 people within an area of 1km2
  • Internal flooding (excluding to basements) of at least one property or business for one week or longer
  • Flooding of one or more items of critical infrastructure, which could include hospitals, health centres, clinics, surgeries, colleges, schools, day nurseries, nursing homes, emergency services (police, fire, ambulance) stations, utilities and substations.

 

Caused a transport link to be impassable:

  • Motorways, trunk roads, Class A and B highway closures shall all be investigated.
  • Class C highways – 10 hours or more unless the route is the only means of access, or is primary route for critical infrastructure then reduce to 4 hours
  • Class U highways – 24 hours or more unless the route is the only means of access, or is primary route for critical infrastructure then reduce to 4 hours
  • All rail link closures shall be investigated.

 

Any flooding event that a risk management authority deems significant but does not meet the agreed thresholds should be put forward to the Strategic Flooding Group committee for consideration.
