Hamburg (Germany): the floodable city

Goal 1.1

Including joint City Port measures to prevent inundation and flooding of the port and connecting infrastructure in strategic planning documents, and through a suitable land management policy.

Goal 8.2

Revising the status of port and City Port heritage to properly reflect the site’s historical significance.

Challenge(s)

How can port cities tackle the issue of rising sea levels and the risk of coastal flooding?

Best Practice

Regardless of the debate surrounding the extent of rising sea levels due to climate change, this growing risk can be considered at a very early stage of development projects, specifically in their urban planning and architectural aspects. However, rather than merely adapting existing facilities to cope with greater environmental challenges, this resilience strategy also offers the opportunity to create brand-new spaces. This way, the project can be used for longer if the possibility of flooding is already an integral part of the design. Correspondingly, HafenCity public places were designed for this purpose.

This good practice also includes objectives 1.1 (Including joint City Port measures to prevent inundation and flooding of the port and connecting infrastructure in strategic planning documents, and through a suitable land management policy) and 8.2 (Revising the status of port and City Port heritage to properly reflect the site’s historical significance) of the AIVP’s 2030 Agenda.
