Please use this page to find out the latest information for our Houghton Brook Flood Storage Area.

COVID-19 Update

In line with government advice, we are continuing to deliver all of our Flood Risk Management projects where it is safe for our teams and delivery partners to do so. We are following the latest guidance from Public Health England regarding safe working on construction sites. The safety of our staff, partners and the communities we work in remains a priority for us.

On 18 May, our construction partner, BAM Nuttall, began on site for early enabling works, including some site clearance and setting up the site compound. This work was supervised by an ecologist to ensure that there was no impact on nesting birds or other wildlife. Main construction activities are planned to start in late June and the project is expected to be completed by spring 2021

Below are some photos of the site setup:

The Houghton Brook Flood Storage Area (FSA)

Central Bedfordshire Council granted planning permission for the construction of the Flood Storage Area in December 2019.

Our objectives of the scheme are:

  1. to reduce the risk of flooding to people and property along the Houghton Brook and River Lea in Luton
  2. to create a better place for people and wildlife that is more resilient to the impacts of flooding and climate change
  3. to work with local communities to improve their understanding of flooding, how it impacts them and how they can be more prepared.

Funding

The total cost of this project is £8.5 million and it is funded by Defra, Thames Regional Flood and Coastal Committee, SEMLEP Local Growth Fund and Luton Borough Council.

Below is a summary of our scheme

Why are we doing this work?

Luton has a long history of flooding from the River Lea and its tributaries, in particular where the Houghton Brook joins the River Lea around Toddington Road. In 2007, Luton Central Fire Station, the A6, local roads and Wardown Park were all impacted by flooding.

Our project will benefit approximately 600 residential and commercial properties who will have improved protection from flooding in Luton, as well as key roads and other infrastructure.

In order to reduce flood risk, our project involves building a flood storage area (FSA). The FSA is designed to fill and hold water at times of heavy rainfall, when river levels are high, and to allow water to drain away slowly into the Houghton Brook as river levels reduce. The FSA will consist of an earth embankment to hold back water. Another structure will control the water flowing out of the FSA. By controlling the flow, water is stored in the FSA, reducing the risk of flooding to areas downstream.

We have also allowed for space in the FSA for some surface water runoff from the surrounding area. This is water that collects during heavy rainfall on impermeable surfaces like concrete and paving. After heavy rainfall you may see water collecting in smaller attenuation ponds within the main FSA.

It is important to note the scheme will not eliminate the risk of the flooding for all residents in Luton. Please consider the steps you can take to be more resilient to flooding, this may include:

  • ensuring you are signed up to our free Flood Warning Service, and understanding what to do for each level of warning
  • working with your neighbours to create a community flood plan so you know who may be able to help a venerable resident in times of flood
  • gathering essential items in a personal flood kit so you are ready to respond

Engaging with communities

Unfortunately, subject to current Government restrictions we will not be holding any public engagement events. We will be using this webpage as our primary way to keep you informed. We are always keen to receive your feedback and answer your questions so please do get in touch at the address below. We will also work with our partner, Luton Borough Council, to contact people who will directly benefit from a reduced risk of flooding in Luton.

Houghton Brook environmental improvements

The Houghton Brook will be an attractive green corridor with public open space and recreational areas, creating a better place for people and wildlife. Occasionally, when there is water in the storage area, this will form quite a large water body. This will naturally and safely drain away into the Houghton Brook. Other smaller areas of water will fill after heavy rainfall and these may stand for a longer time, providing additional habitat.

As part of the project we will be realigning Houghton Brook and we will ensure this continues to provide a valuable wildlife corridor that people can enjoy.

As part of the project we will be incorporating species rich grassland and meadows will increase the number of important plant species, with most flowers in bloom over the summer months. Many other species, such as bumble bees, butterflies, birds and bats, will benefit. We will also be planting a variety of native trees and shrubs which will create pockets of improved habitat for birds and insects, and ensure that over time the landscape improves as the trees start to mature and grow tall.

Construction

The construction works for the flood storage area are expected to last 8-9 months. We will make every effort to limit disruption to the local community in the construction phase. Where possible, we will use the new Woodside Link road to minimise traffic impacts to local residents. Our contractors BAM Nutall are adapting their usual work practices to ensure they fit in with the latest Public Health England guidelines.

Footpath and Cycleway

We will need to divert the public footpath and cycleway around the flood storage area to accommodate the embankment; this will be will be re-installed once the works are complete.

The existing Right of Way and cycle path along Houghton Brook will be temporarily closed in the summer and diverted around the site to keep the public safe during construction. The cycle path will initially remain open, but will need to be closed as the embankment starts to take shape. Alternative access will be available via Kestrel Way and the cycle paths next to the Woodside Link. The replacement Right of Way, footpath and cycle path should be ready to open later in 2020-21.

We will continue to update this page as the project develops to keep you informed. Thank you for visiting. If you would like any more information about the scheme, please see the links below.
