"30. [The World Heritage Committee] notes that the pressures on historic urban areas arising from inappropriate or inconsistent development controls, rapid, uncontrolled and planned development, including large development projects, additions that are incompatible in their volume, mass tourism, as well as the accumulated impact of incremental changes have continued within numerous World Heritage properties and in their buffer zones and settings, and considers that these present potential and actual major threats to the Outstanding Universal Value (OUV) of properties, including their integrity and authenticity, as well as increasing their vulnerability to disasters, including those resulting from climate change;
(…)
34. [The World Heritage Committee] (s)tresses the importance of carrying out Heritage Impact Assessments to evaluate and thereby avoid or manage potential threats to the OUV of the property arising from new urban development projects."

Synthesis based on relevant Committee decisions
The World Heritage Committee recommends to put in place appropriate protection and planning measures and to develop an integrated urban conservation and development tool, in the urban settlement and its wider context, in order to address development pressures, to protect the urban landscape and prevent the construction of new buildings that could have a visual impact (based on Case law on decisions on the State of Conservation).

25. "[The World Heritage Committee] notes with concern that the number of cases of ground transport infrastructure having potential impact on the Outstanding Universal Value (OUV) of World Heritage properties is continuing to grow, and calls upon States Parties to carry out Strategic Environmental Assessments (SEAs) early in the process of transportation planning to allow for potential impacts of the OUV, including those resulting from foreseeable associated future developments, to be identified prior to the development of specific projects;
26. Encourages States Parties to carry out Environmental Impact Assessments (EIAs) and Heritage Impact Assessments (HIA) on ground transport projects, once they are designed, with multiple options to ensure that transportation needs can be met with minimal impacts on the OUV of World Heritage properties."

The World Heritage Committee requests Heritage Impact Assessments and Environmental Impact Assessments of all significant development proposals in the property and of any major transportation infrastructure project, before approval for the schemes is granted and prior to making any decisions that would be difficult to reverse, including definitive location and plans for construction, in order to identify any adverse impacts on the property and ways to mitigate these impacts, and to submit the HIA and the EIA to the World Heritage Centre for review by the Advisory Bodies, in accordance with Paragraph 172 of the Operational Guidelines (based on Case law on decisions on the State of Conservation).
