The planned Mulberry Place and supermarket developments will cause major parking disruption during their construction.
The plans affect some of the town’s most used car parks – in Primrose Hill, the old gas works, the former outdoor pool, and Chapel Lane between North street and the Moot Hall.
The proposals have been passed by Daventry District Council’s planning committee, an all these car parks will be affected by construction work across the two sites.
Henry Boot, DDC’s chosen developer, has drawn up plans to alleviate the problems. The first step will be constructing a temporary 275-space car park on the Eastern Way playing field.
As construction progresses, old car parks will close and new permanent ones will be open. Overall the two sites will go from 647 spaces to 885.
Concerns are already being raised though about the impact on shoppers.
Stepnells, which owns several units in the High Street, says: “The loss of the Primrose Hill car park will detract from the perceived ‘pop in’ convenience of the existing shops.”
The building work could also hit town centre shops and businesses.
La Patisserie, Scallywagz, Orchard Print and Heron Foods have all pointed out they need access to the rear of their units for deliveries.
Orchard Print say: “Access is required for 40ft trailers. Customers also call for heavy and bulky orders. The closure of Primrose Hill car park will also reduce parking for customers and staff.”
Heron Foods also points out it received regular deliveries in articulated lorries and 44ft rigid lorries.
Planning officers say a condition of approval includes details of any arrangements for service access.
