Critical Drainage Area (CDA) projects

Where the projects will take place

We are working on these projects included in the national Flood and Coastal Erosion Risk Management (FCERM) programme:

  • Muswell Hill Critical Drainage Area (CDA)
  • Decoy Brook Critical Drainage Area (CDA)
  • Mill Hill Circus Critical Drainage Area (CDA)

Project stages

Any project in the FCERM programme has 3 key stages, these are:

  • Initial Assessments
  • Detailed Option Assessment
  • Business Case

The business case will need to be approved by the Environment Agency. 

If stakeholders agree, the scheme can go through to Detailed Design and Construction.

When the projects will be completed

We have identified our top 10 priority Critical Drainage Areas (CDAs) from the Barnet’s Local Flood Risk Management Strategy and included them in the national FCERM program.  

The priority CDAs have finished the Initial Assessments stage.
