Flood Risk at York

Flood Risk Rivers and Sea

The presented dataset indicates the probability of flooding caused by rivers or the sea, with cells of 50m being the unit of measurement. Each of these cells is assigned to one of four categories of flood risk, considering the presence and state of flood defences.

Flood Risk Rivers and Sea - Planning

This map covers the flood risk from rivers and sea for planning purposes. This information was produced by the Environment Agency to support the flood risk assessments that are part of planning applications. The flood risk varies from Flood Zone 1 (low risk) to Flood Zone 3 (high risk).

If your development is in high risk zone, you will have more requirements to comply in order to get your development underway.

Flood Risk Surface Water

The flood risk from surface water shows the extent of flooding, the depth and the level of hazard. These flood risk maps don't take into account drainage systems for instance road drainage, pumping stations, ditches etc. Because of this, this information can not be used to evaluate the flood risk for single properties. However this gives you an indication of the potential risk of flood areas within your neighbourhood.

Extent of Flooding

The extent of flooding refers to the area that could be at risk of flooding from surface water. This information is not to be used at property level.

Please contact us if you need a detailed flood risk assessment.

Flood Risk Reservoirs

This is the maximum extent if a reservoir were fail and release its water. This is the worst case scenario, it's unlikely that any actual flood would be this big. This data is intended for emergency planning services only.

Historic Flood Map

These are areas of land that have been previously flooded in England. It is possible that an area has been flooded but has not been recorded. This data does not indicate if a property has been flooded internally.

Reduction in Risk of Flooding from Rivers and Sea due to Defences

This database indicates where areas have reduced flood risk from rivers and sea due to the presence of flood defences.

The dataset has been created to help initiate conversations about the impact our flood defences have on the risk of flooding from the rivers and sea,and as a prompt to find out more about the flood defences in a particular area of interest. It does not replace any local, more detailed information

Flood warning areas

This map shows the areas where the Flood Warning Service is provided by the Environment Agency. We recomend you register to the service if your property is expected to flood from fiver or sea.

5 Day Flood Forecast

The Flood Guidance Statement (FGS) is a 5-day risk-based product for England and Wales
  • It is produced by the Flood Forecasting Centre (FFC)
  • It shows the forecast level of flood risk for the coming 5 days for surface water, river, groundwater and coastal flooding
  • It uses a detailed risk matrix approach, based on a combination of likelihoods and impacts
  • It forecasts at a local authority scale
  • It provides a summary forecast for the 6 to 10 day period where necessary
Overview
Minor coastal flooding impacts are possible along parts of the Dorset coast today (Thursday) . Minor inland flooding impacts are possible but not expected in England and Wales today. The overall flood risk is VERY LOW.

Flood Risk Solutions

We need to adapt our way to live and learn to live with flooding. We can limit the impact of flooding by working together at a development, community and house level. These are some initiatives that you can start applying.

Green infrastructure is a cost-effective and sustainable flood management approach that gathers and removes water at its source.

Integrate sustainable drainage system Integrate sustainable drainage system

Use green roofs to soakaways. Make them part of the landscape. This will reduce their costs and increase the quality of your development.

Re-use water within buildings Re-use water within buildings

Re-use rainwater for the irrigation of plants, gardens and also within buildings. Design your development with temperate climate areas in which water is used.

Design with flooding as a principle Design with flooding as a principle

It is easy to forget that flood water can be part of the development. Although we can protect individual dwellings from flooding, we can also make the external areas enjoyable and part of the flood zone.

Create Zero carbon developments Create Zero carbon developments

Zero carbon will reduce climate change and in turn the risk and impact of future flooding.
