Is the status up to date?

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. Near SL4, 1 project has a status that may be out of date (pending for over two years, or approved with a permission expiry date already passed). Check the council's planning register for the latest decision.
