- Also recalling the state of conservation reports and reactive monitoring mission reports of March 2009, March 2010 and October 2010 that underscored the impacts of the Cinta Costera project, in particular the Maritime Viaduct, and the poor state of conservation of the property;
- Notes the progress with developing a Management Plan, with quantifying the number of buildings at risk and with work on the streetscapes, and undergrounding networks, and reiterates its deep concern about the overall state of conservation of the property and regrets that no sufficient progress has been made in comprehensively and sustainably addressing issues, or in implementing the emergency Action Plan agreed in 2009;
- Also regrets that the State Party decided to launch the construction of the Cinta Costera Phase III (Maritime Viaduct) that modifies in an irreversible manner the relation of the historic centre with its wider setting;
- Requests the State Party to submit by 1 February 2015 a significant modification to the boundaries to allow it to justify a revision of the Outstanding Universal Value of the property;
- Also requests the State Party to invite as soon as possible a high-level World Heritage Centre/ICOMOS Reactive Monitoring Mission, guided by the World Heritage Centre, to discuss the different possibilities of this modification;
- Considers that in the absence of the implementation of the request made in this decision, the property would be deleted from the World Heritage List at its 39th session in 2015 , in conformity with Chapter IV.C of the Operational Guidelines .
