Introduction In order to effectively assess the fire cover provision which is required to achieve the stated aims of the Authority an assessment of the risk factors for Kent and Medway needs to be undertaken. This document forms part of a suite of Risk Profile documents which segment the county into 19 geographically identifiable areas thereby allowing for a simplification of the assessment of the county wide risk.
Kent and Medway Fire and Rescue Authority (KMFRA) divide the county into 19 clusters based on internal working arrangements and the day to day work activities of its personnel. These clusters have been in use since 2011 to analyse and report incident activity, creating a wealth of information which is used to gain a deep understanding of activity within each cluster. It therefore follows that these clusters be used as a backdrop to provide risk information, as this allows for a continuity of analysis across the RERP2 project. The map below illustrates these clusters.
Information regarding risk factors has been obtained from a number of sources in order to provide a detailed level of risk for individual clusters.
Much of the data within this document has been derived from information provided by the Office of National Statistics (ONS) a Government department charged with the collection and publication of statistics related to the economy, population and society. In March 2011 the ONS conducted the most recent census of the population. It is this information which is used extensively throughout this document as the most accurate census data available.

Each Borough Council within Kent and Medway has produced a Local Development Plan. These documents detail the strategic developments which are planned for their area of responsibility, and as such are referenced to give an indication of the future risk within the cluster.
KMFRA has significant experience in planning for emergencies in sites of specific risk; as such numerous sites have been identified through previous internal work. These sites have been included within this document.
This document describes the risk factors found in the Sevenoaks cluster.

RERP – Sevenoaks Cluster Risk Profile
Cluster Demographics and Population Risk Factors The most current and widely available information with which to highlight the population risk factors is the 2011 census data. This data has been used to describe the community composition of each cluster.
The following charts and tables provide information regarding the population, age and gender of the community which live within the Sevenoaks cluster.
The male to female ratio is comparable to the Kent and Medway average.
The age breakdown when compared to the Kent and Medway average indicates a lower proportion of 20-34 year olds live within the cluster.

One family households are categorised by the presence of children into those with dependent children, those with non-dependent children only, and those with no children. Other households are categorised by the presence or absence of dependent children. Married includes those in a civil partnership. Households with dependent children include natural, adopted and step-children aged 0 to15 and those aged 16 to 18 in full-time education or training for work and living at home with parent(s) or grandparent(s) (excluding those who have a spouse, partner or child(ren) living in the household). Non-dependent children are all those living in a household with parent(s) or grandparent(s) who are not classified as dependent children. Other households include: households of more than one family; households comprised of unrelated adults sharing; those including one family and other unrelated adults; all full-time student households; and households in which all occupants are aged 65 and over.
In March 2011 there were 8,147 households with dependent children in the area.
This represents 31.2% of households in the area. In addition 6,959 (26.65%) of households were comprised of a single person.
These figures are comparable to the rest of Kent and Medway.

Deprivation The indices of deprivation are used to classify households based on four selected household characteristics:
Employment Education Health and disability Housing
The map below shows the deprivation levels for the Sevenoaks cluster by output area when compared to the rest of Kent. Using the indices of deprivation as an indicator, the darker areas represent progressively more deprived localities.
There is a well-established correlation between dwelling fires and the measures of individual household characteristics detailed above.

Overall Cluster Risk Each Fire and Rescue Service has been provided with a tool with which to analyse risk within their area of responsibility. This tool is called the Fire Service Emergency Cover Toolkit, commonly referred to as FSEC.
FSEC can create a number of models relating to risk within the Kent and Medway area. The dwellings and special service models are detailed below as they provided the best representation of the work conducted by KMFRA and consist of incidents which present the highest level of risk to the community, namely Fires and Road Traffic Collisions.
Dwellings The dwellings model shown below shows the risks associated with the number of predicted fatalities within a localised area. This risk is derived from a number of factors including, but not limited to, demographic factors, historic incidents within the local area, the response provided by KMFRA into the output area, and underlying risk derived from nationally recognised risk factors such as the number of pensioners or the amount of rented accommodation within the area.
10
RERP – Sevenoaks Cluster Risk Profile
Special Service (RTC) The special service model shown below shows the RTC risks associated with the number of predicted fatalities within a localised area. This risk is derived from the amount of RTC incidents within a predefined area of the road network and other geographical features where rescues may be necessary.

Geodemographic Segmentation Geodemographic segmentation refers to a range of methods which can be used to classify and characterise neighbourhoods or localities based on the principle that people who live near each other are likely to have similar demographic, socio-economic and lifestyle characteristics. This information allows KFRS to understand the demographics, lifestyles, preferences and behaviours of the people of Kent and Medway and thereby specifically target those who need us most.
KFRS uses a product called Mosaic Public Sector (Mosaic) as a source of this information. Mosaic categorises each property into fifteen top level categories each of which is further subdivided into further groupings, however these groups provide a level of detail which is not required for this document.
Each top level category is named and described in the table below.
Category Description Well-off owners in rural locations enjoying the benefits of Country Living country life Established families in large detached homes living Prestige Positions upmarket lifestyles High status city dwellers living in central locations and City Prosperity pursuing careers with high rewards Thriving families who are busy bringing up children and Domestic Success following careers Mature suburban owners living settled lives in mid-range Suburban Stability housing Elderly people with assets who are enjoying a comfortable Senior Security retirement Householders living in inexpensive homes in village Rural Reality communities Younger households settling down in housing priced within Aspiring Homemakers their means Residents of settled urban communities with a strong Urban Cohesion sense of identity Educated young people privately renting in urban Rental Hubs neighbourhoods Mature homeowners of value homes enjoying stable Modest Traditions lifestyles Single people privately renting low cost homes for the short Transient Renters term Families with limited resources who have to budget to Family Basics make ends meet Elderly people reliant on support to meet financial or Vintage Value practical needs Urban renters of social housing facing an array of Municipal Challenge challenges

Building Usage as a Risk Identifier There is a well-established process embedded within Fire and Rescue Services nationally to recognise an identified building usage type as an indicator of the risk posed by that building. As such research has been undertaken to gain as much information on building usage within Kent and Medway, and wherever possible a quality assurance process has been undertaken to verify this data.
The first stage of acquiring this data was through the use of an Ordnance Survey Product called AddressBase Premium which is provided to KFRS under a public license agreement. It provides a geographic dataset of addresses, properties and land areas where services are provided. By comparing known property types gained through fire safety inspections and operational intelligence with the information contained within AddressBase it has been found to be a suitable dataset to use when analysing risk data.
However, part of the established practice of using an identified building usage type as an indicator of the risk involves Fire and Rescue Services recognising that approximately 80% of the total risk from fire fatalities involves buildings where people sleep. This 80% of total risk can be attributed to specific categories of building usage:
Hospitals Care Homes Houses of Multiple Occupancy (HMOs) Hotels
For this reason additional research and cross-matching has been undertaken on specific building usage types to ensure a robust dataset. This research has involved building on the work undertaken in a previous Review of Emergency Response Provision Project and combining it with current information.
As an example of this work AddressBase lists 324 HMOs within Kent and Medway. Operational intelligence and fire safety records strongly indicate that there are significantly more HMOs within Kent and Medway than are recorded within AddressBase. The reason behind this may lie in the licensing scheme for HMOs which is conducted on a purely voluntary basis. It is suspected that only the licensed HMOs are recorded within AddressBase thereby giving a false impression of the number of this type of building Kent and Medway.
Additional internal data has therefore been used to supplement the dataset for HMOs to provide a more accurate assessment of risk for Kent and Medway and the individual clusters.

RERP – Sevenoaks Cluster Risk Profile
Other Building Risk It is well established that the use of a building has a large impact on the amount of risk that building poses to a community. This section details the usage of buildings other than dwellings.
Sleeping Accommodation Risk Those buildings which provide sleeping accommodation account for approximately 80% of total other building risk due to them having people sleeping in them overnight. These buildings are:
Hostels Care Homes Houses of Multiple Occupancy (HMOs) Hotels

Specific Risks within the Cluster KFRS has a process which identifies sites which pose a specific risk to the community should an incident occur at these locations. These sites are subjected to specific planning and training regimes in order to ensure KMFRA has the ability to respond correctly and effectively to the risks associated with these sites.
The Sevenoaks Cluster has 9 such sites.

COMAH Sites The Control of Major Accident Hazards Regulations 1999 (COMAH) and their amendments 2005, are the enforcing regulations within the United Kingdom which are applicable to any site which stores or handles large quantities of industrial chemicals of a hazardous nature. The regulations operate on two levels which depend on the sites status, either Top Tier or Lower Tier sites.
The Sevenoaks cluster has no COMAH sites within its boundary.

RERP – Sevenoaks Cluster Risk Profile
Infrastructure Risk The risk posed by the clusters infrastructure can be broken down into 4 main areas:
Roads Rail Aviation Ports
35
RERP – Sevenoaks Cluster Risk Profile
Roads The Sevenoaks cluster contains a significant amount of the County’s Major roads including the M25 and M20. The cluster also contains some major trunk roads including the A21 and A25.
36
RERP – Sevenoaks Cluster Risk Profile
There are 355 miles of carriageway within the cluster. The Sevenoaks cluster road composition is comparable to the average for the rest of Kent and Medway.
37
RERP – Sevenoaks Cluster Risk Profile
Rail A number of rail lines pass through the Sevenoaks cluster.
38
RERP – Sevenoaks Cluster Risk Profile
Aviation There are no commercial airports within the Sevenoaks cluster.
The greatest risk is posed by Kent and Medway’s proximity to London airports including Heathrow and Gatwick and the fact that Kent and Medway sits below the flight path for many International flights.
Kent and Medway have a long established aviation tradition and there are many small airfields for light aircraft throughout the county.
The map below shows the major airports in the South East of England namely:
London Heathrow Airport Gatwick Airport London Biggin Hill Airport London City Airport Lydd Airport Rochester Airport
39
RERP – Sevenoaks Cluster Risk Profile
Ports Kent and Medway have a significant amount of coastline and as such numerous small ports and harbours. Most villages and towns along the coast contain a mooring location which coupled with the various inland marinas along the rivers of the county present a level of risk to the community.
The map below shows the major ports, harbours and docks within the Kent and Medway namely:
Folkestone Dover Sheerness Thamesport Chatham Ridham Ramsgate Whitstable Dartford Grain LNG The Medway Ports

Sites of Specific Scientific Interest (SSSI) Sites of Specific Scientific Interest (SSSI) are sites which support plants, animals, protected species or natural habitats that find it difficult to survive in the wider countryside. These unique and varied habitats have developed over hundreds of years through management practices such as grazing and forestry, and require active management to maintain their conservation status.
The Sevenoaks cluster contains SSSIs as shown in the map above, including;
Scords Wood and Brockhoult Mount Dryhill Sevenoaks Gravel pits Greatness Brickworks Knole Park Hubbards Hill One Tree Hill and Bitchet Common Polebrook Farm Cowden Meadow and Cowden Pound pastures Lingfield Cernes

Existing KFRS Arrangements The Sevenoaks cluster contains three fire stations, Sevenoaks, Westerham and Edenbridge. Each station has a set number of resources which are based at the station, these resources can be crewed through differing crewing systems and provide differing capabilities as detailed in the table below.
Station ID Station Name Crewing Appliances 1x HRP 68 Sevenoaks D 1x P 69 Westerham OC 1x RP 70 Edenbridge OC 1x P
OC = On-call
This crewing model uses firefighters who are called into the station when required from a remote location. These appliances are available either during the day, during the night or both as required by the Authority.
D = Day Crewed
This crewing model uses firefighters who are available at station during the day and on call at night. N.B. this cluster does not have any Day Crewed stations
W = Whole time shift
This crewing model uses firefighters who are continuously available for deployment 24 hours a day and are based at station. N.B. this cluster does not have any Whole time stations.
P = Pump
These appliances make up the majority of the fleet and provide the backbone of our response. They carry no specialist rescue equipment.
RP = Rescue Pump
These appliances are located at stations where it has been deemed that a requirement for specialist rescue equipment exists. They carry some specialist rescue equipment and can respond to most Road Traffic Collisions.
HRP = Heavy Rescue Pump
These appliances are located at strategic stations and carry specialist rescue equipment. They are able to provide a respond to all incident types.
43
RERP – Sevenoaks Cluster Risk Profile
The map below illustrates the area appliances can respond to from their base locations within 10 minutes. This includes the time period taken for the crews to respond into the station from another location, get ready and leave the station. This time period is known as turnout time.
The turnout time has been standardised as one minute for crews that are already on station and five minutes for crews responding from home or other locations.
Effectively, the turnout time reduces the distance an appliance can respond to within 10 minutes.
44
RERP – Sevenoaks Cluster Risk Profile
Future Development The Sevenoaks Cluster is comprised of only the Sevenoaks Local Borough Council.
Each local council is required to produce a Core Strategy Document under the National Planning Policy Framework which has been referenced to assess the projected development and associated future risk within the cluster.
45
RERP – Sevenoaks Cluster Risk Profile
The Sevenoaks Core Strategy Document identifies three locations for major development:
Sevenoaks Swanley Edenbridge
Population and Housing As with National trend predictions the population of the Sevenoaks Cluster is set to increase over the next ten years, necessitating an increase in available housing stock.
To meet the projected housing requirement within the Sevenoaks Borough 3,300 dwellings are required, the Core Strategy targets that at least two thirds of new housing is to be provided in Sevenoaks, Swanley and Edenbridge.
Major Developments There are no further major developments highlighted for the Sevenoaks cluster other than those detailed above.
