As a result of this and other changes, notably plans for abandoned industrial land along the Avon, the city's status as a World Heritage Site was reviewed by UNESCO in 2009. The decision was made to let Bath keep its status, but UNESCO has asked to be consulted on future phases of the Riverside development, saying that the density and volume of buildings in the second and third phases of the development need to be reconsidered. It also demands Bath do more to attract world-class architecture in new developments.
