The Urban Design Manual for the Historic Center of Asunción (CHA) is a technical and strategic instrument that guides and unifies criteria for the design of public space in the city’s central area, promoting its patrimonial, environmental, and social revitalization. It was developed within the framework of the Urban Resilience Project for the Asunción Waterfront, led by the Government of Paraguay with financing from the World Bank.

The document is conceived as a methodological guide that organizes design criteria and technical sheets applicable to public spaces—streets, plazas, and parks—incorporating principles of universal accessibility, sustainability, climate comfort, identity, and urban maintenance.

Its scope is limited to the Historic Center and its buffer area, and it is binding for all public and private works developed within this territory.

The Manual is structured into four chapters:
• Urban Morphology: defines typologies of streets, sidewalks, and intersections.
• Green and Blue Infrastructure: integrates nature-based solutions and sustainable drainage strategies.
• Materiality: proposes materials for pavements, edges, and surfaces.
• Urban Furniture: specifies street furniture, lighting, signage, and complementary elements.

Its purpose is to ensure coherence in urban interventions, enhance environmental quality, and strengthen the environmental and social resilience of the Historic Center as a symbolic and functional core of Asunción. In this sense, the Manual proposes a vision of the Historic Center as a living and evolving territory, where urban design articulates memory, identity, and future.
