Flood Map for Planning

Our Flood map for Planning allows you to interact with different flood data in detail. All flood information at your finger tips

We have created this flood map for planning to help you understand in detail the flood risk that can affect your development.

Key advantages of using our maps:

Our Flood Map

In our flood map for planning, you will be able to see the risk of flooding from rivers or sea (planning), flooding from surface water and reservoirs or whether the development is affected by surface water run-off.

We have taken this information directly from the Environment Agency databases and prepared it so you can check in detail if your development need a flood risk assessment.

If you are uncertain about your requirements, give us a call, we are happy to talk you through the options.

• Flood Risk Map For Planning - Rivers And Sea

The Flood Map for Planning (Rivers and Sea) includes several layers of information. This dataset covers Flood Zone 2 &3.

This dataset is designed to support flood risk assessments in line with Planning Practice Guidance ; and raise awareness of the likelihood of flooding to encourage people living and working in areas prone to flooding to find out more and take appropriate action.

The information provided is largely based on modelled data and is therefore indicative rather than specific. Locations may also be at risk from other sources of flooding, such as high groundwater levels, overland run off from heavy rain, or failure of infrastructure such as sewers and storm drains. Follow the link above to read more.

• Flood Storage

This dataset covers Flood Storage Areas. It shows those areas that act as a balancing reservoir, storage basin or balancing pond. Their purpose is to attenuate an incoming flood peak to a flow level that can be accepted by the downstream channel. It may also delay the timing of a flood peak so that its volume is discharged over a longer time interval.

We have assumed that flood storage areas act perfectly and give the same level of protection as when our assessment of the area was carried out. Flood storage areas do not completely remove the chance of flooding and can be overtopped or fail in extreme weather conditions. Follow the link above to read more.

• Areas Benefiting from Defences

The Flood Map for Planning (Rivers and Sea) includes several layers of information one of which is areas benefiting from defences.

This dataset shows those areas that benefit from the presence of defences in a 1 in 100 (1%) chance of flooding each year from rivers; or 1 in 200 (0.5 %) chance of flooding each year from the sea. If the defences were not there, these areas would flood in a 1 in 100 (1%)/ 1 in 200 (0.5 %) or larger flooding incident. Follow the link above to read more.

• Spatial Flood Defences

The Flood Map for Planning (Rivers and Sea) shows the areas across England that could be affected by flooding from rivers or the sea.

It also shows flood defences and the areas that benefit from them.

The Flood Map is designed to raise awareness among the public local authorities and other organisations of the likelihood of flooding and to encourage people living and working in areas prone to flooding to find out more and take appropriate action.

• Historic Flood Map

Historic Flood Map is a GIS layer showing the maximum extent of all individual Recorded Flood Outlines from river, the sea and groundwater springs and shows areas of land that have previously been subject to flooding in England.

Records began in 1946 when predecessor bodies to the Environment Agency started collecting detailed information about flooding incidents, although we may hold limited details about flooding incidents prior to this date.

• Flooding Risk Reservoirs

This is the simplified version of the outline Reservoir Flood Map Outline (Extent) as shown on the Environment Agency website. Simplified in this context refers to the fact that unlike the detailed product, individual reservoir flood map extents are not shown separately, and one merged outline shows the maximum flood extent for all reservoir flooding scenarios together.

This is the simplified version of the outline Reservoir Flood Map Outline (Speed) as shown on the Environment Agency website. Simplified in this context refers to the fact that unlike the detailed product, individual reservoir flood map speeds are not shown separately, and one merged outline shows the maximum flood speeds for all reservoir flooding scenarios together.

This is the simplified version of the outline Reservoir Flood Map Outline (Depth) as shown on the Environment Agency website. Simplified in this context refers to the fact that unlike the detailed product, individual reservoir flood map depths are not shown separately, and one merged outline shows the maximum flood depth for all reservoir flooding scenarios together.

• Flooding Risk - Areas With Critical Drainage Problems

The Development Management Procedure Order (2015) requires that the Environment Agency is consulted on developments within Areas with Critical Drainage Problems (ACDPs). This layer displays the geographical coverage of ACDPs across England. Attribution statement: © Environment Agency copyright and/or database right 2016. All rights reserved.

• Flood Risk – Indicative Flood Risk Areas

This metadata record is for Approval for Access product AfA256. Flood Risk Areas identify locations where there is believed to be significant flood risk. The EU Floods Directive refers to Flood Risk Areas as 'Areas of Potentially Significant Flood Risk' (APSFR). Flood Risk Areas have been defined by the Environment Agency (main rivers and the sea) and Lead Local Flood Authorities (surface water). Other sources of flooding are not covered. This dataset includes Flood Risk Areas defined for both Cycle 1 (December 2011) and Cycle 2 (December 2018).

• Indicative flood risk areas clusters

The Indicative Flood Risk Areas are primarily based on an aggregated 1km square grid Updated Flood Map for Surface Water (1 in 100 and 1000 annual probability rainfall), informally referred to as the “blue square map”. • Cluster Maps – are aggregations of 3km by 3km squares that each contain at least 4 (in Wales) or 5 (in England) touching "blue squares" (i.e. 1km grid squares where one of the thresholds above is exceeded)

• Indicative Flood Risk Areas - Communities at Risk data

Shapefile for Indicative Flood Risk Areas generated using the Environment Agency's Communities at Risk Approach. This information is provided by the Environment Agency for use by LLFAs in their review during 2017 of Preliminary Flood Risk Assessments and Flood Risk Areas under the Flood Risk Areas. it must be used in conjunction with data for Indicative Flood Risk Areas generated by the Environment Agency using the cluster method as well.

The Indicative Flood Risk Areas are primarily based on an aggregated 1km square grid Updated Flood Map for Surface Water (1 in 100 and 1000 annual probability rainfall), informally referred to as the “blue square map”.

This dataset is a component of Indicative Flood Risk Areas

• Indicative Flood Risk Areas - People Sensitivity Grid

The Indicative Flood Risk Areas are primarily based on an aggregated 1km square grid Updated Flood Map for Surface Water (1 in 100 and 1000 annual probability rainfall), informally referred to as the “blue square map”. This dataset is a component of Indicative Flood Risk Areas (shapefiles)

• Indicative Flood Risk Areas - People Sensitivity by LLFA

The Indicative Flood Risk Areas are primarily based on an aggregated 1km square grid Updated Flood Map for Surface Water (1 in 100 and 1000 annual probability rainfall), informally referred to as the “blue square map”. This dataset is a component part of Indicative Flood Risk Areas (shapefiles)

• Indicative Flood Risk Areas - 1km Blue Squares

The Indicative Flood Risk Areas are primarily based on an aggregated 1km square grid Updated Flood Map for Surface Water (1 in 100 and 1000 annual probability rainfall), informally referred to as the “blue square map”. This dataset is a component of Indicative Flood Risk Areas (shapefiles)
