  3. Also recalling the concerns expressed by the 2012 mission regarding the critical level of urban development reached since inscription and its cumulative impacts on the Outstanding Universal Value (OUV) of the property, the need for new tools to guide the development process towards sustainable development that protects the attributes of the OUV, and the specific recommendations of the 2015 mission to the property,
  4. Noting the information provided by the State Party including design changes and a Heritage Impact Assessment for the proposed Vienna Ice-Skating Club – Intercontinental Hotel – Vienna Konzerthaus project, the resolution of the City Council of Vienna dated 5th May 2017, the intention to analyze and review existing urban planning instruments, and the advice regarding proposed projects in the the Karlsplatz-area,

  6. Notes with regret that the changes made to the proposed Vienna Ice-Skating Club – Intercontinental Hotel – Vienna Konzerthaus project do not comply with the previous requests of the Committee, and that the proposed project remains inconsistent with the recommendations of the 2012 and 2015 missions and would adversely affect the OUV of the property if implemented in its current form, and therefore reiterates its requests to the State Party to submit a further revised design to the World Heritage Centre, for review by the Advisory Bodies, before any decisions are made regarding its implementation, in accordance with Paragraph 172 of the Operational Guidelines;
  7. Reiterating its concern that the High-Rise Concept abolishes exclusion zones for high-rise buildings in the Vienna urban areas, without having applied appropriate instruments of control for height, volume and urban density respecting the OUV of the property, and that the Glacis Master Plan permits the construction of buildings of a scale that would have an adverse impact on the urban form and character of the Glacis area, expresses its regret that these instruments have not been repealed or substantially amended, and therefore also reiterates its request to the State Party to facilitate the preparation of revised planning rules and guidelines, which:
    1. Establish parameters for the urban density as well as specific standards for building height and volume for the property and buffer zone,
    2. Safeguard the urban morphology that is an essential attribute of the property,
    3. Encourage sustainable development in the property and its buffer zone in harmony with its OUV,
    4. Require that all high-rise projects are evaluated through a comprehensive Heritage Impact Assessment (HIA), prepared in accordance with the ICOMOS Guidance on HIAs for Cultural World Heritage properties, including reference to 3D visual simulations, so that the effects of the proposed development on the OUV of the property can be properly considered;
    5. Incorporate the intent of the resolution of the City Council of Vienna, dated 5 May 2017 within the revised planning rules and guidelines;
  8.

  9. Urges the State Party not to amend the current land use and development plans and to halt any further approvals for high-rise projects, pending the preparation of the revised planning rules, and submit the proposed designs and related HIAs for any future high-rise projects to the World Heritage Centre for review by the Advisory Bodies, in accordance with Paragraph 172 of the Operational Guidelines;
  10. Regrets that the State Party has not complied with the requests expressed by the Committee in Decision 40 COM 7B.49, in particular related to the lack of change to existing planning controls and the inadequate extent of change proposed for the Vienna Ice-Skating Club – Intercontinental Hotel – Vienna Konzerthaus project;
  11.

  4. Takes note of the conclusion of the reactive monitoring mission that so far, the Outstanding Universal Value (OUV) of the property has been preserved in part thanks to its isolation but that the region is undergoing rapid changes characterized by numerous planned infrastructure developments;
  5. Notes with concern the many infrastructure projects being developed around the property, which could potentially impact on its OUV, and requests the State Party not to authorize infrastructure inside the property or in its vicinity, without having conducted an Environmental Impact Assessment (EIA) in conformity with IUCN’s “World Heritage Advice Note: Environmental Assessment” and to ensure that all EIAs are validated by the Scientific Council of the property and submitted to the World Heritage Centre prior to making any decisions that would be difficult to reverse, in accordance with Paragraph 172 of the Operational Guidelines ;

Also requests the State Party to ensure that the draft EIA for the water sourcing system linked to the extension of the Tasiast mine is completed to assess its potential impacts on the OUV of the property, and submitted to the World Heritage Centre prior to making any decisions that would be difficult to reverse, in accordance with Paragraph 172 of the Operational Guidelines;
  8. Appreciates the fact that no oil or mining exploration permits were attributed within the property, but also expresses concern about potential impacts if any of the on-going exploration projects lead to exploitation, in particular, in oil blocks close to the property where exploratory drilling is going forward in 2014;
  9.
