Councillors have granted planning permission to a new business park at Inverness Airport by 10 votes to five.
Two community councils objected to the development, which will be built in phases over 50 years.
Go-ahead was given by Inverness, Nairn, Badenoch and Strathspey planning committee.
Croy and Culloden Community Council said it had been promised a hearing before the application went before councillors for a decision.
Ardersier and Petty Community Council also objected to the plans.
Councillors decided last month to visit the site before taking a decision on the planning application.
