The Inner Moray Firth 2 Main Issues Report has been put on the Highland Council website for consultation.
You can visit that consultation page here and see a copy of the report. Nairn is on page 197. There is a map that shows the preferred sites (green), alternative sites (yellow) and non preferred sites (pink) by Highland Council.
Sandown is preferred for development by Highland Council and also part of the Farmers Showfield. The Gurn imagines that both sites will attract considerable comment.
