What is the risk of coastal flooding to Lincolnshire?

Coastal flooding is caused by high tides, low pressure weather systems, and surge conditions caused by strong winds blowing large waves towards the shore.

Low atmospheric pressure allows the sea’s surface to bulge upwards in what is called a ‘storm surge’. If strong persistent onshore winds occur, these increase the height of the surge and generate waves that can damage the coastline.

Surges can occur at any point on the tidal cycle; at low tide they rarely cause flooding but at high tide the resulting flooding can be significant.

If there is a very large sea surge in the North Sea, with tides, gale force winds and potentially heavy rainfall, many coastal regions and tidal reaches of rivers could be affected, from South Yorkshire down the coast as far as Kent. Many coastal and estuary defences would be overtopped or breached, and drains would back up. Inundation from these breaches would be rapid and dynamic, with minimal warning and for some people, no time to evacuate.

How could flooding
affect you and your property?

  • Risk to life
  • Disruption to utilities (electricity and water supply)
  • Damage to property, businesses and agricultural land
  • Widespread structural damage
  • Risk to life of livestock
  • Flooding of properties for up to 14 days
  • Pollution and contamination of local environments
  • Evacuation of residents

  • Short, medium and long term businesses and agriculture
  • Loss of accommodation for those whose homes or businesses are flooded
  • Damage to national critical infrastructure (North Sea oil and gas installations)
  • Unrecoverable damage to businesses

We can all be better prepared to
respond and recover from flooding

Follow these practical steps so you and your family can be better prepared for flooding.


Check if your property is at risk

Find out if your property is within a flood risk area.


Write a personal flood plan

Find guidance and checklists to help you prepare for flooding.


Check on your neighbours

Identify neighbours who may need assistance or who may be able to provide assistance to you, in case of evacuation.


Create an emergency contact list

In an emergency, even a person with the best of memories may not remember critical phone numbers.


Make sure you have house insurance and check it covers flooding

Floods are the most common and costly natural disaster. Just a few inches of water can cause thousands of pounds of damage.

Fit appropriate flood protection devices to your property

What is being done to become
better prepared?

We work together to:

  • Prioritise support to vulnerable residents in the highest risk areas.
  • Assist people to evacuate an area if they require it.
  • Provide a helpline so people can request support.
  • Produce multi-agency plans so that every responding organisation knows what they can do, at the right time, to support people who may be affected by flooding.
  • Test the multi-agency plans through a variety of exercises.
  • Keep the public informed of the changing situation via local media stations, social media and the LRF website.
  • Maintain two-way communication with central government to ensure that any additional national resources can be provided to support the local response.

We can request military support when it is appropriate to assist with the response and rescue phase.

Lincolnshire County Council is our Lead Local Flood Authority and is responsible for pluvial flooding from overwhelmed drains.
