Welcome to the Future Resilience for Chelmsford project page
The Environment Agency have created this page to provide easy access to information on the Future Flood Resilience for Chelmsford project. This page will provide the most up to date information on the scheme as it progresses, so please keep checking back for what's new. The page was last updated in June 2025 to provide updated information on the ongoing flood risk modelling, replacing information on the channel survey from last summer.
Background
The Environment Agency, in partnership with Chelmsford City Council, are investigating options for reducing flood risk to the city of Chelmsford.
Following the successful completion of the flood risk management works at Chelmer Village back in the 2010s, the Environment Agency is now working to identify other measures that may be required to improve the resilience of Chelmsford to flood risk.
With a changing climate, the flood risk to the city is only likely to increase. Therefore, it is paramount that the Environment Agency, with Chelmsford City Council and other stakeholders, work together to better understand, prepare for, and mitigate the causes and impacts of flooding.
What are the next steps for the project?
Later this year, we will review the early results from the model to check that it reflects flooding experienced in the past. The flood risk model is expected to be completed by Autumn 2025 (previously we had hoped to do this by Spring 2025), following which a short list of options will be developed that could potentially reduce flood risk in Chelmsford. The project team will then consult on the options with stakeholders and the public, before identifying a preferred set of economically viable, buildable and sustainable measures to take forward to the next stage of appraisal and design.

Future Flood Resilience for Chelmsford Project has finished this stage
April 2021 - March 2023
We gathered information and made the case for public funding to improve flood protection in Chelmsford following delivery of the flood defence in Chelmer Village in the 2010s. This high-level business case was approved in March 2023, allowing us to move to the next stage.
Initial Appraisal Phase
Future Flood Resilience for Chelmsford Project has finished this stage
April 2023 - December 2025
We reviewed the available information and existing flood risk data, identifying areas where further information and data needed to be collected, and improvements completed.
Flood Risk Modelling Phase
Future Flood Resilience for Chelmsford Project is currently at this stage
September 2023 - March 2026
The flood risk modelling phase involves improving our understanding of flood riskby developing a new hydraulicmodel. Utilisingnewly collected channel survey and topographic data, updated hydrometric data, and the latest software and methods, we will create a robust flood risk model thatgives us more confident and accurateoutputs.These will be used to improve our understandingof flood risk mechanisms in Chelmsford,improve our flood warning and informing capabilities, and to investigate different measures to reduce flood risk.
Outline Business Case
this is an upcoming stage for Future Flood Resilience for Chelmsford Project
Spring 2027
The Outline Business Case will complete further investigations into potential measures to reduce flood risk to Chelmsford, developing a short list of ideas for informal consultation with stakeholders and the public. The Outline Business Case will identify a preferred option, which will be a set of economically viable, buildable and sustainable measures to take forward to the next stage of appraisal and design, and delivery mechanism.
Final Business Cases- selected measures
this is an upcoming stage for Future Flood Resilience for Chelmsford Project
Summer 2028
Each measure, or measures, will be developed by different risk management authorities as is appropriate. EachFinal Business Case will involve completing detailed designs and assessments for consultation with stakeholders and the public and to gain approval from relevant authorities.
Construction
this is an upcoming stage for Future Flood Resilience for Chelmsford Project
Following completion of business cases, measures to reduce flood risk to the city will be delivered. Where opportunities ariseto buildwe will construct sooner.
