Plans must be kept up to date and Government suggests a review is required at least every five years. Plans should also look ahead into the future at least 15 years. The current local plans, which include the Joint Core Strategy (JCS) and separate site allocations documents, were adopted at various times between 2011 and 2016. An early review of plans is often beneficial to reflect changing local circumstances or changing national planning policies.
The evidence supporting local plans goes out of date over time and needs reviewing as well. The current timetable is to have the local plan examined by an independent inspector in 2021 and for each local authority to adopt it in 2022. Whereas current plans look to 2026, the new Greater Norwich Local Plan will be to 2038.
