Over the following decades after Geddes's plan was realized the area began to decay and there was significant public lament and dissatisfaction with the decay of the city. This deterioration was later used as justification for the rapid redevelopment of the area in the 1950s. However, it was noted that this disapproval of the decay of the city quickly changed to nostalgia when old buildings began being razed to make way for new development. Resultantly significant effort was made to preserve the historical neighborhoods planned by Geddes and in 1984 the Council for the Preservation of buildings and Sites was established to protect them.
