Shoreline Management Plan 1999 (SMP1)

The SMP1 covers the coastline of Cornwall and the Isles of Scilly. The SMP1 was superseded by the SMP2.

The first round of SMPs were carried out in the late 1990s. At the time of the original SMP studies, the Government guidance suggested that SMP’s should be reviewed and, if  necessary, updated approximately every 5 years.

There were four initial SMP's (SMP1) covering the coastline of Cornwall and the Isles of Scilly:

Note that all of the documents within the SMP1 links above are PDF files scanned from paper documents.

Each of these documents outlined the most appropriate action for their stretch of coastline.

In each plan, to facilitate easier reference to information and assessment of issues, the coastline was divided into a number of lengths, termed 'Areas'. In providing this sub-division an initial assessment of the likely processes was carried out to ensure that any given Area, had a single specific physical characteristic.

A further division of these areas into 'Units' based upon coastal processes and coastal usage was made. This enabled strategic coastal defence policies to be developed which take account of the interactions of any processes, e.g. sediment supply, transport and deposition mechanisms, and the demands from the natural and developed environments.

For each Unit, one of the following  strategic coastal defence options was decided upon, based on clear guidance:

  • Do-nothing
  • Retreat the existing line
  • Hold the existing line
  • Advance the existing line

These strategic policy options were all collated, together with the background information and research to form the SMP.

The Local Authorities adopted these plans and  subsequent coastal defence decisions have followed these policies.
