Section 1. Coastal Consents Works and Development Matrix

This matrix illustrates the potential consents that are likely to be needed for coastal development and works. It is not prescriptive and as all developments will be different in their scale, location and nature it can only act as a guide to the exact consents that may be needed. It is an applicants responsibility to apply for the correct consents and you should always refer to the consenting body for a definitive answer. This is particularly the case where the work is maintenance based such as replacement or refurbishment as local rules may apply. Minor works may also be exempted.

Once you have looked through the table, please refer to our page on consents details for more information on consents, consenting authority and exemptions. Please also read our Other Considerations page as this includes information on important issues that may need to be considered when applying for consents.

Footnotes:

  1. Planning permission applies within the jurisdiction of the local planning authority (LPA), this is normally works or development above the Mean Low Water Mark (MLWM). However in some estuaries and rivers, such as the River Hamble, the LPA boundary can extend into the river or estuary hence planning permission for waterside works or development should be sought.
  2. Only applicable where the activity takes place within a Harbour or the Harbour Limit. Harbours have different terms of reference so you will need to contact the relevant Harbour Authority to definitively check whether a Licence is needed.
  3. Landowner is normally the Crown Estate below MLWM. The Crown Estate also owns approximately half of the foreshore. There is a public right of fishing that may exempt some fishery activities from landowner consent, contact the Crown Estate for a definitive answer.
  4. Flood Defence Consent covers all works in, under or over a 'main river'. Main rivers in the Solent include Lymington Harbour, Beaulieu River, River Itchen, River Hamble, Portsmouth, Langstone and Chichester Harbours, River Yar, Newtown Creek, River Medina, Wootton Creek and Bembridge Harbour. It also covers sites close to sea defences. The Environment Agency is the consenting authority.
  5. Applicable if you are going to be making a discharge to surface waters during the development or as a consequence of the works undertaken. The Environment Agency is the consenting authority.
  6. Mean High Water Mark (MHWM).
  7. Mean Low Water Mark (MLWM).
