Introduction
Resilience of historic areas
While negative impacts of climate-related and other hazards on urban areas are widely discussed in
contemporary literature and research, their impacts on cities and communities, which are inextricably
linked to historic areas, have not yet been studied extensively. Combined work on disaster risk reduction
and climate change adaptation in and for historic areas, with their unique structure, calls for advanced
technologies, models, methods, processes and tools. To make a historic area resilient, the local
community, municipal staff, practitioners and decision-makers need to address both the chronic stresses
posed by climate change as well as the shocks and existing risks posed by other disasters. However, to
date, typical management frameworks for disaster risk management (DRM) and climate change
adaptation (CCA) still consider shocks and chronic stresses in isolation. Furthermore, the term “city
resilience” or additionally, “community resilience” can mean many different things to different actors,
depending on the context in which it is applied.
The ARCH DRM/CCA Framework
The aim of the CEN/WS ARCH, a temporary working group, was to further develop the ARCH Project’s
DRM/CCA Framework, together with a broader community of experts, including municipal staff. The
framework was created to help, for example, practitioners, decision-makers, heritage managers, public
administrators, and other actors in the field of DRM, CCA, and historic area management to:
– acknowledge the need for socially just resilience building activities,
– understand which steps are necessary to develop a Resilience Action Plan that combines DRM and
CCA processes and that takes into account the needs and opportunities of historic areas when
building resilience,
– provide guidance on how to operationalize the different steps of the DRM/CCA Framework,
– provide guidance on which stakeholders to involve in each step of the DRM/CCA Framework,
– provide a conceptual structure for the use of different supporting tools and materials within the steps
of the DRM/CCA Framework.
The content in this document is based on the DRM/CCA Framework of the ARCH project, which centres
on historic areas. Nonetheless, the DRM/CCA Framework can also be applied to other use cases in other
parts of a given city, not necessarily only on historic areas.
The framework is based on the DRM cycle proposed by Jigyasu, King, and Wijesuriya in the UNESCO
manual on managing disaster risk for world heritage [1] as a starting basis and extends it with the climate
change adaptation planning cycle of Climate ADAPT’s Urban Adaptation Support Tool [2]. This combined
planning cycle is then further extended with considerations from topic-specific frameworks relevant to
historic areas, like the Culture in City Reconstruction and Recovery Framework [3], the SMR European
Resilience Management Guideline [4], and the RESIN Conceptual Framework [5].
CWA 17300 series on “City Resilience Development”
This document complements the already existing standards series CWA 17300 on “City Resilience
Development”. This supports the uptake and consideration of the standards content in relation to
enhance resilience in cities and communities. The standards series consists of the following documents:
– CWA 17300 City Resilience Development – Operational Framework
– CWA 17301 City Resilience Development – Maturity Model

Introduction
Resilience of historic areas
While negative impacts of climate-related and other hazards on urban areas are widely discussed in
contemporary literature and research, their impacts on cities and communities, which are inextricably
linked to historic areas, have not yet been studied extensively. Combined work on disaster risk reduction
and climate change adaptation in and for historic areas, with their unique structure, calls for advanced
technologies, models, methods, processes and tools. To make a historic area resilient, the local
community, municipal staff, practitioners and decision-makers need to address both the chronic stresses
posed by climate change as well as the shocks and existing risks posed by other disasters. However, to
date, typical management frameworks for disaster risk management (DRM) and climate change
adaptation (CCA) still consider shocks and chronic stresses in isolation. Furthermore, the term “city
resilience” or additionally, “community resilience” can mean many different things to different actors,
depending on the context in which it is applied.
The ARCH DRM/CCA Framework
The aim of the CEN/WS ARCH, a temporary working group, was to further develop the ARCH Project’s
DRM/CCA Framework, together with a broader community of experts, including municipal staff. The
framework was created to help, for example, practitioners, decision-makers, heritage managers, public
administrators, and other actors in the field of DRM, CCA, and historic area management to:
– acknowledge the need for socially just resilience building activities,
– understand which steps are necessary to develop a Resilience Action Plan that combines DRM and
CCA processes and that takes into account the needs and opportunities of historic areas when
building resilience,
– provide guidance on how to operationalize the different steps of the DRM/CCA Framework,
– provide guidance on which stakeholders to involve in each step of the DRM/CCA Framework,
– provide a conceptual structure for the use of different supporting tools and materials within the steps
of the DRM/CCA Framework.
The content in this document is based on the DRM/CCA Framework of the ARCH project, which centres
on historic areas. Nonetheless, the DRM/CCA Framework can also be applied to other use cases in other
parts of a given city, not necessarily only on historic areas.
The framework is based on the DRM cycle proposed by Jigyasu, King, and Wijesuriya in the UNESCO
manual on managing disaster risk for world heritage [1] as a starting basis and extends it with the climate
change adaptation planning cycle of Climate ADAPT’s Urban Adaptation Support Tool [2]. This combined
planning cycle is then further extended with considerations from topic-specific frameworks relevant to
historic areas, like the Culture in City Reconstruction and Recovery Framework [3], the SMR European
Resilience Management Guideline [4], and the RESIN Conceptual Framework [5].
CWA 17300 series on “City Resilience Development”

1 Scope
The document specifies a resilience-building framework for historic areas within cities and communities
that defines and combines disaster risk management (DRM) and climate change adaptation (CCA)
activities in an integrated approach. The framework is applicable for historic areas that face natural and
climate change-induced hazards. The framework includes a:
– characterisation of historic areas and their exposure to natural and climate change-induced hazards,
– set of requirements and recommendations on how historic areas can become more resilient,
– step-by-step process to manage disasters, and to perform and monitor resilience-building activities.
This document is intended to be used by decision makers and technical staff at the city/community and
historic area levels, as well as by councillors working on risk and vulnerability assessment, climate
change adaptation and resilience enhancement. Other stakeholders who may wish to use the document
include disaster risk managers, heritage managers, public administrators, sustainability and resilience
officers, critical infrastructure managers, service providers, emergency service providers, civil society
associations, non-governmental organisations, academic and research institutions, as well as
consultancies.
