6.5 Surface Water Run-off

All development will have regard to the drainage hierarchy of the London Plan. Developments will incorporate Sustainable Drainage Systems (SUDS) to manage surface water run-off.

As part of the FRA (Policy 6.4), developers will carry out ground investigations to check the suitability of SUDS for infiltration and storage. SUDS schemes focussing entirely upon infiltration will not be acceptable due to the presence of London Clay in Colindale.

The following are some good examples of the types of SUDS that can be used in the Colindale area:

  1. Flood storage (retention ponds)
  2. Permeable paving
  3. Green roofs
  4. Rainwater harvesting schemes - water butts installed on new development

The Council will either enter into S106 discussions with the developer relating to the future maintenance of the SUDS or attach relevant planning conditions.
