In 2011 Truro residents set up a Save Truro campaign against a planned Waitrose store on a greenfield development outside Truro.
On 15th December 2011 Cornwall Council's Strategic Planning committee gathered to decide the fate of 55 acres of farmland outside the built area of Truro, in an Area of Great Landscape Value which regularly produces invaluable winter feed for one of the best dairy farms in Cornwall. The Committee voted to defer the decision so that further work to be done on traffic modeling, testing the splitting of Waitrose from Cornish Food Hall to see if either or both can be accommodated in the town centre (where they should be), and how the Planning authority and Applicants can make the proposal to establish a ‘buffer’ zone more substantial.
In 2007 residents in Calenick, Truro were concerned that Tesco could relocate to a green-field site as part of the Higher Newham development which included plans for 800 houses on part of the 100-acre site. Calenick Resident Association submitted a petition against the development in March 2007.
