Waterfront Design

Waterfront design is the planning and design of the edge where a city meets a river, harbour, lake or sea: its promenades, parks, quays, public buildings and the flood defences that hold the line. Most urban waterfront projects today are regenerations, turning docks, shipyards, rail yards and polluted banks into public space while managing the floods and tides that made them hard to use in the first place.

What is waterfront design?

Waterfront design sits between urban design, landscape architecture and civil engineering. Its subject is not a single building but a strip of city along the water: the continuous public route at the edge, the streets that lead down to it, the buildings that face it, and the wall, slope, steps or wetland that separate land from water. A good waterfront lets people reach and touch the water, keeps working uses such as fishing, ferries or markets where they still matter, and stays safe when the water rises.

It differs from coastal architecture, which deals with individual buildings by the sea and how they resist salt, wind and storms. Waterfront design works at the scale of the district and the public realm, and it is as likely to happen on a river or canal as on the coast. A whole family of related work deals with rivers in particular; see riverfront development.

Most of the field's landmark projects share one story. Ports moved downstream to deeper water and container terminals, railways and industry left the centre, and cities were left with large, central, often contaminated sites along their oldest water edges. Waterfront design is the discipline of giving those edges back to the public without losing their character or exposing new neighbourhoods to flood risk.

A short history of waterfront design

The modern waterfront regeneration began in Baltimore. The city's renewal programme was extended in 1963 to 240 acres around the Inner Harbor, where office headquarters and hotels rose around the shoreline and a public park and promenade were added. The Harborplace festival marketplace by The Rouse Company opened in 1980, alongside the National Aquarium and the Maryland Science Center. According to the history of Baltimore's Inner Harbor, the scheme influenced as many as 100 other cities.

Barcelona followed with a different emphasis. Before the 1992 Olympic Games, Port Vell, the old harbour, was a run-down area of empty warehouses, railway yards and factories. It was rebuilt as part of an urban renewal programme, and a pedestrian walkway, the Rambla de Mar, now connects La Rambla to Port Vell, with a swing bridge that lets ships enter and leave the harbour.

Bilbao showed how a declining industrial river could become the centre of a city again. At Abandoibarra, the public company BILBAO Ría 2000 was given the task of converting a shipyard, port facilities and a railway line into a promenade along the estuary, a riverside park and a mixed district, following a master plan by Cesar Pelli, Diana Balmori and Eugenio Aguinaga. Work began in 1998, the promenade and riverside park opened in 2003, and the action was completed in 2011.

Two later projects added flood risk to the brief. In Hamburg, HafenCity is turning an area once dominated by port and industrial uses on the Elbe into a new inner-city district. In Ahmedabad, the Sabarmati Riverfront project lists among its objectives reducing erosion and flooding, diverting sewage to clean the river, and bringing new life to the centre of the city.

Key principles of waterfront design

Public access along the whole edge

The first rule of a city waterfront is a continuous public route along the water. Private plots that reach the edge break the route and turn the water into a view for a few. Baltimore's promenade, Barcelona's harbour walk and Bilbao's estuary promenade all start from this idea, and later schemes treat the public edge as fixed infrastructure that buildings must respect.

Flood defence as public space

Waterfronts are on the front line of storm surges, river floods and sea level rise. The traditional answer, a high wall or dike, cuts the city off from the water. HafenCity Hamburg took the opposite route: apart from the quays and promenades, the district is being raised to between 8 and 9 m above sea level on artificial compacted mounds (warfts). The district keeps its access to the water and its port atmosphere while the raised ground protects it from floods.

"The intensive interaction between land and water is also unique, for despite the risk of occasional flooding, HafenCity is neither surrounded by dikes, nor cut off from the water."

The same logic works at the scale of a suburb. MORE THAN A CHANNEL by Tianyi Jiang, a Runner-up in UnIATA '19, is a landscape design in the South East Wedge of Edinburgh that gives existing watercourses room to flood safely and uses water to bring play to the area. For more on this approach, see flood-resilient architecture.

Bringing people down to the water

A vertical quay wall keeps people at a distance. Steps, terraces, ramps and floating pontoons let them sit at the water's level, dip their feet in, launch a boat or swim. Stepped edges also absorb changing water levels gracefully, since a few steps can disappear at high tide without closing the promenade.

Cape in Flow, an Editor's Choice in the Ripple competition, starts from Istanbul's long social and spatial relationship with water and proposes strategies at both micro and macro scale to make its site an active part of the city again.

Water as a working system

The best recent waterfronts clean and store water as well as framing views. Planted terraces filter runoff before it reaches the river, wetlands hold stormwater, and floating structures can collect litter. In WaterCell Park by Andra Gheorghiu, Alexandru Pomazan, Alexandra Burecu and Irina Panait, a People's Choice Award winner in the Ripple competition, the brief is a regenerative intervention in an Istanbul neighbourhood that opens towards the sea, with water recycling features that serve the wider city.

Keeping the working waterfront

Regeneration has often meant replacing fishermen, boatyards and markets with cafes and apartments. Many designers now argue for keeping working uses where they still serve the city, because they give the edge its identity and its year-round life.

Waterfront design on uni.xyz

Waterfront projects on uni.xyz cluster around competitions such as Ripple, whose entries here are set on the Istanbul shoreline, and Street City Vietnam, which centred on the street market, along with a growing body of thesis work on rivers and canals in South Asia.

Pumakalle Park, a shortlisted Ripple entry by Scott Getz, borrows the stepped travertine pools of Pamukkale and sets them along the Bosphorus as terraced seating, sloping paths and filtration gardens, with an amphitheatre that steps down to the water.

"Rather than flattening the shoreline into a conventional promenade, the design stacks it into cascading tiers that manage stormwater, frame views, and create layered public space all at once."

The fish market is a recurring waterfront theme. The market as a place to gather by Louie T. Navarro, shortlisted at Street City Vietnam, was given a lot set back from the water and chose to reach the river anyway: the market flows into a waterfront promenade, and a broad plaza descends towards the water in long terraces. Revitalizing Karnaphuli Riverbank Fishery Ghat by Md. Emam Meraj Hossain, an UnIATA '26 entry, reorganises a chaotic fish market into a modular waterfront that improves circulation, auctioning and logistics for fishermen and labourers, then becomes a public riverfront with walkways and community spaces after market hours.

Industrial harbours appear too. Forging a New Dawn by Rishu Jaiswal, an UnIATA '25 thesis, reimagines Darukhana, Mumbai's historic shipbreaking hub, with a community centre, a public promenade, a museum of the site's past and safer, reorganised shipbreaking yards.

Editorial journals cover built examples. Pier 22 in Vienna by Mostlikely Architecture opened its first phase in 2024: an 18,000 m² public realm on the Danube Island with a waterfront promenade, a park and working area, and a future cultural kiosk. The Beitang Street Grand Canal project in Wuxi, by Shanghai Daguan and Zebai Landscape, stretches 3.6 km along the canal, combining new construction in the north with selective renovation in the south around a continuous 10 m wide promenade. The topic also includes AGOS by Frialyn, a water hyacinth research and development complex conceived to recover a degraded waterfront through industrial ecology, and a journal on Estudio Herreros' Trosten floating sauna on Oslo's Harbour Promenade.

Challenges and future directions

Climate change is the defining challenge. Sea level rise and heavier rain will test every low-lying promenade, and the choice between walls and designs that let water in will shape cities for a century. Raised ground as in HafenCity, stepped edges and wetlands that can flood are likely to spread, but each needs space, money and long maintenance.

The second challenge is who the waterfront is for. Successful regenerations raise land values, and the fishermen, traders and residents who used the old edge can be priced out. Projects that keep the working waterfront and invest in public space before private plots tend to share the benefits more widely.

Revitalizing Asadganj by Fawjia Afroj, an UnIATA '26 entry, addresses both challenges at once: it aims to turn the historic Chaktai Canal, its warehouses and congested streets, into a connected spine of heritage, trade and public life. Water quality is the third challenge, since many urban rivers remain polluted, and the public edge only works when the water is clean enough to be near.

Waterfront design for students and designers

Waterfronts make strong thesis sites because they combine history, ecology, infrastructure and public life. Useful angles include a fish market or ghat that stays working while opening to the public, a former port or shipyard, a canal choked by encroachment, or a flood defence that doubles as a park. Begin with a section from the street to the riverbed at high and low water: most decisions follow from it. Related topics include landscape design, and open briefs on water, public space and regeneration appear regularly on uni.xyz competitions.

Frequently asked questions

What is waterfront regeneration?

Waterfront regeneration is the redevelopment of former port, industrial or neglected land along a river, harbour or coast into public space, homes, workplaces and culture. Baltimore's Inner Harbor, Barcelona's Port Vell, Bilbao's Abandoibarra and Hamburg's HafenCity are well-known examples.

What makes a good urban waterfront?

A continuous public route along the edge, easy access from the streets behind, places to reach the water, a mix of uses that keeps it active through the year, and flood protection that does not cut the city off from the water.

How do waterfronts deal with flooding?

Options include walls and dikes, raising the ground for buildings and streets while keeping quays and promenades low by the water (as in HafenCity), stepped or terraced edges, and wetlands and parks that store water. Many schemes combine several.

What is the difference between waterfront design and coastal architecture?

Waterfront design works at the scale of the district and the public realm along any body of water. Coastal architecture focuses on individual buildings on the sea coast and how they respond to its climate and hazards.
