This layer shows the locations of dredge spoil deposit sites that are designated as disused (not used for at least 5 years) or closed (not used for at least 10 years or specifically closed). The spoil is usually as a result of navigational dredging (deepening of navigation channels) on the approaches to ports and harbours.
The laying of a permanent mooring or other equipment to hold a vessel requires consent from the relevant landowner. For the seabed, this consent will nearly always come from Crown Estate Scotland, who issue three types of mooring licence.
- Individual: This is suitable for private individuals
- Commercial: A licence for businesses such as ferry operators, boatyards, charter boats and diving vessels
- Associations: Once established, associations are given a seabed agreement enabling them to manage their members’ moorings within a specific area. Associations are suitable for groups of ten or more moorings and provide a degree of security as pressure on areas traditionally occupied by moorings increases.
