Flood Risk Assessment Reports for Properties in Lincolnshire

Lincolnshire is a county located within the East Midlands and Humber region of England with a medium-sized population. It features a network of rivers, which irrigate and nourish its highlands. While the North Sea forms its eastern border, the county has many major rivers traversing its landscape. The three main rivers consist of the River Witham, the River Trent and the River Welland. 

Lincolnshire faces frequent flooding risks due to its proximity to the North Sea and other significant water sources. It’s susceptible to fluvial and surface water flooding, with coastal areas vulnerable to tidal inundation. Six areas across the county are categorised as high risk of flooding, including Woodhall Spa, Boston, Lincoln, Holbeach, Gainsborough, and Skegness, where frequent rainfall leads to river overflow and flooding.

The flood risk assessment cost is as follows:


Minor Development

The flood risks in Lincolnshire

In Lincolnshire, flood risk percentages vary across different regions. Medium-risk areas, exemplified by Lincoln Central, face a 1-3.3% annual risk of flooding. Notably, local features can significantly influence the likelihood of flooding in this region.

In contrast, high-risk areas have a greater than 3.3% chance of flooding, signifying a considerably higher vulnerability. Meanwhile, low-risk areas face a more modest 0.1% annual chance of flooding.

Furthermore, a significant portion of Lincolnshire’s population, approximately one-third, reside in direct flood-prone areas, encompassing 336,500 residents and 212,350 properties exposed to high flood risks. 

Additionally, 12% of all properties throughout the county are categorized as being at high or medium flood risk.

The Environmental Agency plays a pivotal role in identifying and managing high-risk flood zones, offering critical support to mitigate potential losses. This proactive approach aids in safeguarding communities and properties from the significant challenges posed by flooding events.

Our Flood Maps

Our flood risk map tool determines the flood risk assessment for your development.

It has all of the relevant databases. You have all of the flood risk information at your fingertips. Use your postcode and zoom in to find your site. The flood risk map of Lincolnshire shows areas at risk of flooding from various sources like surface water, rivers, and coastal flooding.

Lincolnshire highlands are irrigated by several rivers and water sources which spread across its elevated terrain. With a length of 130 kilometres, Witham River is Lincolnshire’s longest river, originating in Lincolnshire Wolds and travelling through Boston, Lincoln, and Grantham.

Due to its geographical makeup and proximity to the North Sea and several other significant water sources, the county is susceptible to flooding.

Lincolnshire flood investigations show that flooding is highly likely in six areas across Lincolnshire. Woodhall Spa, Boston, Lincoln, Holbeach, Gainsborough, and Skegness are the locations in question. Even in the driest months, the majority of these areas get a lot of rain, which causes rivers to overflow and flood the lower land. Thus, flood risk in Lincolnshire depends on the condition of the weather.

The map highlights information regarding flood defences, and this info can be used to assist people in mitigating flood risk. The map also shows the percentage of flood risk that each area has, and based on the frequency of flooding, these areas are shown in different colours.

Moreover, Lincolnshire’s local flood risk management strategy can be carried out with the help of this map, and the number of people at risk could be minimized.

Frequently Asked Questions

How do I get a flood risk assessment?

Flood risk assessment examines the risk of flooding and the identification of mitigation measures before and after the flood. It can be done by;

  • Gathering information about the area that is prone to flooding and noting down all the current mitigation measures.
  • Identifying the source of flood in the area
  • Estimating the risk of flooding in the area
  • Evaluation of all possible consequences of flooding
  • Identifying potential mitigation measures
  • Provide effective recommendations to reduce flood risks in the future

Is Lincolnshire at risk of flooding?

Given its proximity to the East and the presence of significant rivers within its borders, Lincolnshire is at risk of floods. Additionally, the region has significant rainfall, which causes the river to overflow and raises the danger of flooding. According to the Environment Agency, there are a number of places in Lincolnshire that are very susceptible to floods. These locations are primarily close to the Witham and Glen rivers, as well as the shoreline between Mablethorpe and Skegness.

Do I need a flood risk report?

Given the county’s high risk of flooding, a flood risk report is always required to determine the likelihood of flooding in a specific area. The report will provide information regarding the possible risks, prevention strategies and mitigation measures for flooding. Notably, a flood risk report is also needed to purchase a property that is not vulnerable to flooding.

Which areas of Lincolnshire are prone to flooding?

Lincolnshire has a risk of fluvial flooding and surface water flooding. Its coastal areas are prone to floods from tidal inundation. The following six areas across Lincolnshire are at a high risk of flooding: Woodhall Spa, Boston, Lincoln, Holbeach, Gainsborough, and Skegness.

What areas are at risk of flooding in Lincolnshire?

Various areas in Lincolnshire are at risk of flooding, including;

  • High to medium risk: Boston, Louth, Horncastle, and Sleaford 
  • Low risk:  Grimsby Cleethorpes, Scunthorpe, and Grantham. 

Environment Agency has provided maps to identify the risk of flooding in the area.

How far above sea level is Lincolnshire?

Lincolnshire is 200 feet above sea level. Its maximum elevation is 225 m, minimum elevation is -2 m, and average elevation is 28m.

What areas are mostly affected by floods?

Various properties in the area of Spalding, Marke Rasen, and Pinchbeck were hit by the recent flood in August 2022, and the whole county is vulnerable to climate change.

More than one-third of the population is at high risk of flooding. In addition, areas between Bilsby and Thorpe St Peter are at a high risk of tidal flooding.

Has Skegness ever flooded?

Lincoln’s east coast; Skegness was hit by a major flood on 31 January 2023.

Skegness, including Winthrop, Seacrof, Seathorne, and Lincoln Road, is a flood warning area but has received no warning of floods currently. 

Is Mablethorpe a flood risk?

The North Sea is close to Mablethorpe. Flooding is likely to occur since it is on the shore of Lincolnshire. It has a significant danger of flooding during severe weather events and has previously suffered flooding.

When did Lincolnshire flood?

It flooded in 1953, and a considerable amount of the country was submerged.

When did Boston Lincolnshire last flood?

Due to tidal flooding, Boston frequently experiences floods. In December 2013, over 800 properties in Boston were affected. This led to establishing barriers in December 2019 and the project’s completion in 2020.
