32% of applications still shown as pending in REPD were submitted more than two years ago, and only 37% of pending records were updated in the last 12 months, so some of them may already have been decided. Projects belong to Cardiff by location (nearest postcode to the REPD grid reference); decisions are counted by the planning authority named in REPD.
