UK council pilots AI to improve flood risk planning

Northumberland County Council in the UK is piloting the use of AI to assist with flood risk planning decisions in 2024.

The trial will run until September, with results expected by the end of the year.

AI will be used alongside human planning officers to review flood risk assessments submitted by developers, aiming to identify issues more quickly, and check compliance with planning policies.

Council staff will retain full oversight, with AI serving only as a support tool and not making any final decisions.

The initiative received £725,000 (US$974,762) in funding from the UK government’s Regulatory Innovation Office.

Northumberland, which has experienced major floods in recent years, is also involved in other AI projects, including efforts to predict flash floods.

The findings and a governance framework for responsible AI use will be shared with other local authorities.

🧠 Food for thought

Implications, context, and why it matters.

AI assists with flood risk assessments; flash flood prediction is a separate project

  • Northumberland runs two AI efforts 1, one for Flood Risk Assessments (FRAs) in planning files and another, FloodAI, for flash flood prediction in six river catchments 2.
  • A triage tool helps planning officers pull key details from developer documents and check them against planning policy, which matters because the council handles thousands of applications with uneven FRA quality 1.
  • FloodAI uses machine learning from Northumbria University to forecast flash floods in places like Hepscott and Ovingham, where hydraulic models (computer-based water flow simulations) struggle with rapid rises 3.
  • The planning tool aims to cut FRA review time without lowering safety standards 4, while FloodAI sends early warnings to communities that lack Environment Agency (England’s environmental regulator) alerts 3.

AI planning tools create procurement opportunities for compliance vendors

  • Northumberland’s £725,000 pilot hints at wider UK demand 1, and central government is tendering £10 million for an AI planning tool to cut decision times from eight weeks to four 5.
  • Developers and engineering consultancies could offer pre-submission FRA compliance checkers that mirror council AI validation rules so applicants catch policy issues before filing 1.
  • Software firms can pursue 25 local projects under the Department for Environment, Food & Rural Affairs (Defra) £200 million Flood and Coastal Innovation Programme with integration for AI flood prediction 2.
  • A new governance framework from Northumberland is due by year-end, giving compliance consultancies a template to help other councils set planning AI policies 1.
