The outlets - the operators of which have not yet been made public - will form the latest part of the redevelopment of the sprawling plot.
South Ribble Borough Council’s planning committee has granted outline permission for the facilities, as well as giving the green light to the detail of previously approved plans for a business park.
Work is currently ongoing on the construction of the first phase of up to 950 homes elsewhere on the wider site, with those properties having been given the go-ahead back in November 2019.
The filling station and drive-thru will be located to the east of the development and accessed from Titan Way, with Graeme Thorpe, the agent for the application, describing them as “complementary” to the overall test track scheme.
The commercial aspect of the permission will see a total of 70 units for "light industrial" use created across two separate parcels of land - 50 on a section to be known as Lower Titan, which will share the same access as the petrol station and drive-thru, and 20 on what will be called Upper Titan, for which a new entry point will be opened up from Aston Way.
Mr. Thorpe told the planning committee meeting that “a large number” of companies had already signed up for the units, which he said would “help support the local economy, providing valuable space for local businesses to grow and assist in creating employment growth within the borough”.
He added: “[With] buffer landscaping proposed along the southern and western boundaries to separate the site from the future residential phases…the proposed development will be read as an extension of the Moss Side industrial estate.”
Plans for an intervening parcel of land which sits between the two approved industrial parks will be brought forward at a late date, councillors were told.
Committee member Phil Smith said that the vision for the redundant site - which was last in regular use in 2005 - had always been based on the principle that “just building houses wasn't good enough”.
“We needed to build in jobs at the same time - and that is exactly what this does.”
The industrial buildings will range from just over seven to just over nine metres in height and will all be of a similar design, featuring a mixture of glazed sections and grey panelling.
Between two and nine parking spaces have been allocated to each unit depending upon its size, while bike storage will be shared between clusters of buildings.
The five-year funding of a bus service for the site, which is required as part of the residential development, will be triggered only upon the occupation of the 50th property.
However, highways officials at Lancashire County Council concluded that if the industrial units were completed before that point, the existing 112 bus service would be “suitable and capable of servicing the development in the interim”, according to a report presented to committee members.
