Coasttocity

Coasttocity is a planning concept and umbrella term for strategies that aim to shape coastal urban areas as integrated, resilient, and accessible cities. It encompasses policies, designs, and governance approaches intended to balance shoreline development with the protection of coastal ecosystems and public coastal access.

Origin and scope of use: The term has appeared in urban planning discussions as cities confront rising sea levels, intensified coastal development, and the need for sustainable waterfronts. It is used to describe a range of initiatives from policy frameworks to specific redevelopment projects that connect coastal protection with urban growth.

Core principles: Coasttocity centers on resilience to climate risks, including floods and storm surge, through nature-based solutions and engineered defenses. It emphasizes public access to the shoreline, mixed-use and higher-density development near the coast, adaptive zoning that can respond to changing conditions, and data-driven risk assessment. Community involvement and transparent governance are considered essential to ensure equitable outcomes.

Applications and components: Typical applications include waterfront redevelopment plans, coastal transit corridors, living shorelines and floodable parks, and the integration of housing, commerce, and employment opportunities along waterfronts. Design elements often combine ecological restoration with resilient infrastructure, such as elevated promenades, permeable surfaces, and microgrids to maintain services during disruptions.

Benefits and criticisms: Proponents cite increased economic vitality, enhanced climate resilience, and improved public access. Critics caution about high implementation costs, potential displacement or gentrification, governance complexity, and the need for reliable data to guide decisions.
