The area is defined as follows:
The River Tavy between Vigo Bridge and Meadowlands swimming pool forms its south eastern boundary, which then wraps around the swimming pool and runs along the canal to Canal Road.
The boundary then runs north westwards along Canal Road, Chapel Street and West Avenue so that all premises to the east of that line are included.
The boundary crosses West Street from West Avenue to Rocky Hill to include all the premises to the east along West Street and up King Street as far as Madge Lane. From Madge Lane the boundary heads eastwards to include all of Market
Street, Pym Street and Barley Market Street before running along Old Exeter Road as far as, and including, the Brook Street supermarket and car park.
It returns to the River Tavy to include the premises at 1 Parkwood Road and both sides of Vigo Bridge Road.
