3. Notes the results of the April 2013 ICOMOS advisory mission to the property, invited by the State Party;
4. Takes note of the Heritage Impact Assessment (HIA) for the hydroelectric power plant Lehne and information provided by the State Party concerning a number of proposed new projects which may constitute negative impacts on the Outstanding Universal Value (OUV);
5. Encourages the State Party to continue to provide to the World Heritage Centre any development proposals before their official approval in line with Paragraph 172 of the Operational Guidelines for review by the Advisory Bodies;
6. Requests the State Party to initiate the modification of the project designs and proportions of the Residential Buildings City Life Rehrlplatz, the project at Schwarzstrasse 45 / Ernest-Thunstr. 2 and the Nelböck Viaduct Rainerstrasse / Bahnhofsvorplatz and to carefully consider all other developments proposed on the basis of HIAs, in conformity with the ICOMOS Guidelines on Heritage Impact Assessments for World Heritage cultural properties, before any building permission is granted;
7. Reiterates its request to revise the draft Management Plan and to fully implement the recommendations of the 2009 World Heritage Centre/ICOMOS reactive monitoring mission;
8. Expresses its concern about the apparent lack of adequate, legislative and planning mechanisms to protect the property from the various proposed, often aggressive, urban and infrastructure developments as well as a lack of an officially approved management system, which regulates compulsory participation of all concerned agencies in the review of these proposals;
9. Also requests the State Party to integrate standard requirements for HIA in urban planning and development approval policies, and to strengthen legal mechanisms for the protection of monuments in their setting, especially through an expansion of the Austrian Monument Protection Law;
10. Further requests the State Party to submit to the World Heritage Centre, by 1 February 2015 , a report on the state of conservation of the property and the implementation of the above, for examination by the World Heritage Committee at its 39th session in 2015.
