Shock figures have revealed that more than 100,000 properties in Norfolk are at risk of being flooded.

A report to Norfolk County Council shows that 100,077 properties in the county are at risk from three types of flooding while hundreds of thousands of other properties have escaped being placed in the danger zone.

And the large number of properties at risk has helped place Norfolk, which has 396,000 homes, in a national top ten list for flooding fears.

The details of the large section of the county's families, homeowners and businesses facing flood waters are contained in a report to be discussed by the council on Tuesday.

A map in the report shows the flood hot zones with Norwich, King's Lynn, Great Yarmouth, Dereham, Thetford, North Walsham, Sheringham and Cromer said to be in the firing line.

According to a council breakdown of the 100,777 properties, 46,121 are at risk from tidal flooding, such as the 2007 tidal surge, while 37,991 are at risk from surface water flooding and 15,965 are at risk from fluvial,(river or stream) flooding.

The figures mean that according to Defra the county is ranked tenth on a risk list of 149 lead local flood authority areas.

On Tuesday the issue of how Norfolk tackles and can handle floods will be discussed by the county council's cabinet scrutiny committee.

Senior council leaders will hear how flood management in the county is complicated by several factors - its size, the number of dispersed communities at threat and the high risk of fluvial and tidal flooding, as the events of November 2007's surge showed with parts of Yarmouth being evacuated as a precaution in case tidal waters inundated homes.

Tuesday's county hall meeting comes four months after it was revealed that more than 300 homes on the outskirts of Norwich at Drayton were vulnerable to heavy rain flood waters - mirroring parts of other communities across the county who have problems with localised flash flooding, such as North Walsham

The committee will also hear how Norfolk is preparing itself for future flooding through a local flood risk management strategy and how it has taken on broad recommendations from a 2007 national review of flooding issues.

Included in the county wide action plan is the creation of four specialist boat and 10 first responder flood rescue teams for the fire service.

Other measures include a study into surface flooding in Norwich to help draw up an action plan, improving drainage systems and closer co-ordination between relevant organisations.

The MP for Yarmouth Brandon Lewis welcomed Tuesday's chance to scrutinise flood arrangements in the county but he added a note of caution on how the flooding report could create a false impression of the risks involved.

He said: 'Obviously in Yarmouth we are well aware of what has happened and what could have happened.

'It(flooding) is something we have to keep on top off. But I am always cautious when lines are drawn up on maps as they can cause unnecessary fear and worry over flooding.'

Paul Morse, chairman of the cabinet scrutiny committee and who represents North Walsham East, said: 'Flooding is obviously a very important issue for Norfolk and represents a significant risk for thousands of homeowners and businesses.

'My own division was badly affected by tidal flooding in 2007 and surface water flooding in 2008.

'Managing the risk long-term is a key issue for the county council.

'The cabinet scrutiny committee has received a number of reports on flood risk since the Pitt Review as new legislation has been introduced and been appraised of the key issues for the county council.

'This report brings the committee right up to date with the current situation and gives members the chance to examine where the authority is in terms of flood risk management and planning.'

Tuesday's meeting starts at 10am in the Edwards Room at County Hall.
