Hurricane Katrina lasted only eight days and ended nearly 15 years ago, yet the residents of New Orleans are given daily reminders of the presence it wrought in their city after levees constructed by the Federal government failed to redirect excess stormwater. With 80% of the city destroyed, reflecting a citywide property damage price tag of over $125 billion, the broken levees came to signify the largest engineering failure in modern history that left many residents to decide between building off of what had been affected or starting anew. The city's local nuns have been shepherding a former Catholic convent weakened by the man-made disaster and are working with the city of New Orleans to transform the site into Mirabeau Water Garden, a 25-acre wetland that will one of the largest in the United States when complete. Led by Mary Kincaid, sustainable infrastructure program manager at the City of New Orleans project delivery unit, and designed by local firm Waggonner & Ball Architects, the project was originally conceived of by the Sisters of St. Joseph, a group of nuns that once occupied the convent before the building damage became too great to ignore. Their choices, as they have debated them since 2005, were to rebuild the convent or work with the city towards determining a better function for the site. The wetlands will have the capacity to absorb roughly 10 million gallons of stormwater runoff to combat the flash floods that have become common in the city within the last 20 years. Though that water will eventually reach the city's outdated drainage system, the wetland will act as a much-needed filter and partial barrier to prevent sewage overflows. As the most substantial wetland effort taken on by New Orleans in its centuries-long history, the Mirabeau Water Garden will be a signature element of Resilient New Orleans, a city-wide initiative to enact solutions to climate change and other issues facing future generations, and is being developed in accordance with the Greater New Orleans Urban Water Plan, a set of guidelines developed by the State of Louisiana’s Office of Community Development - Disaster Recovery Unit in 2010. The project is estimated to cost $30 million and city officials have already begun soliciting construction bids. The city is hoping to have construction begin in the spring of this year, though no completion date has been set.

On October 26, a historic deal was implemented in New Orleans: the Port of New Orleans (PNO) and the Public Belt Railroad (PBR) swapped riverfront properties, unlocking a key stretch of land to what may soon be the largest uninterrupted public riverfront in the U.S. In the swap, PNO took ownership of a stretch of railroad along the Mississippi River and PBR took ownership of two large wharves–Esplanade Avenue and Governor Nicholls Street Wharves. PBR is owned by the City of New Orleans, which now plans to redevelop both wharves as public space (à la Mandeville Wharf). This redevelopment will connect two existing riverfront parks, Bywater's Crescent Park and the French Quarter's Woldenburg Park. This linkage is key in the long-term vision to develop the entire New Orleans riverfront as one contiguous public parkway, as detailed by Eskew Dumez + Ripple's 2008 Reinventing the Crescent plan. In a press conference on October 27, New Orleans Mayor Mitch Landrieu announced several major riverfront redevelopments, including the keystone wharf redevelopments. The wharves themselves have been allocated $15 million. The other developments announced are generally focused on improving existing public amenities along the Mississippi riverfront from the French Quarter to Bywater neighborhoods. They include a $7.5 million renovation of Spanish Plaza, a $400 million renovation of the World Trade Center at the Four Seasons hotel, a new $37 million terminal for the Canal Street Ferry, a new $7.3 million pedestrian bridge over the railway to the ferry terminal, $6 million in park improvements for Woldenberg Park in the French Quarter, $3 million in green space improvements for part of the Riverwalk, and $31.2 million for expansions to Crescent Park. Many of these projects are ongoing. After a series of major floods this summer, water experts in New Orleans are paying close attention to how the city is spending on water management. "The challenge in New Orleans is that we can't rub two nickels together to wrap up our water infrastructure and drainage problems," said Ramiro Diaz, a designer at architecture firm Waggonner and Ball, in a call with The Architect's Newspaper (AN). "Overall, I think it's a positive development, though. People have been waiting for these riverfront projects for years." Waggonner and Ball were the lead designers behind the Greater New Orleans Water Plan. According to Eskew Dumez + Ripple principal Steve Dumez, his firm is now looking into implementing the western end of the Reinventing the Crescent plan. This would open up riverfront property around the Ernest N. Morial Convention Center, extending the parkway even further.
In early April, the ten finalists in the Rebuild By Design competition unveiled their proposals to protect the Tri-state region from the next Sandy. And in the near future, a jury will select a winner—or winners—to receive federal funding to pursue their plans. But before that final announcement is made, AN is taking a closer look at each of the final ten proposals. Here's how Waggonner and Ball, unabridged and Yale ARCADIS' team plans to create a more resilient Bridgeport, Connecticut. Waggoner and Ball, unabridged Architecture, and the Gulf Coast Community Design Studio propose "Resilient Bridgeport"—a framework of design and planning principles to protect the Connecticut region. "The design proposals are place-specific design solutions ranging from green streets in upland areas to wetland park buffers in coastal areas," explained the team in a statement. "Included, too, are places throughout the city that provide safety and services in times of storm and instruct people on how to transition to a way of living and thriving with water." Specifically, the team protects Bridgeport's South End with a new waterfront berm and offshore breakwaters. At this site, they also create the South End Resilience Education and Community Center—a hub, which includes a co-op, job training programs, a healthcare clinic, and childcare services. During sever weather, the Center transforms into a shelter. The full team includes Waggonner and Ball, unabridged Architecture, the Gulf Coast Community Design Studio, Yale's Urban Ecology and Design Laboratory, and ARCADIS.
[beforeafter][/beforeafter] On September 9th, New Orleans unveiled an innovative proposal for flood management: the New Orleans Greater Water Plan. Designed by Dutch engineers and led by chief architect and planner David Waggonner of locally-based firm Waggonner & Ball Architects, the plan seeks to mitigate the damages caused during heavy rainfalls. The concept is simple: keeping water in pumps and canals instead of draining and pumping it out. The idea is to retain the water in order to increase the city’s groundwater, thereby slowing down the subsidence of soft land as it dries and shrinks. [beforeafter] [/beforeafter] New Orleans is built on swampland and suffers ravaging damages when floods occur, as sea levels rise quickly and the community becomes quickly submerged. The current floodwater management system uses a forced drainage mechanism that dries lands quickly. This heavy reliance on drainage practices leads to damaged lands, severe soil imbalances, and subsidence. As the ground sinks, the city’s infrastructure weakens. Not only does this increase residents' exposure to risk when faced by a natural disaster, but it also diminishes the value of the area’s waterways as public assets. Under the Greater New Orleans Urban Water Plan, floodwaters are retained rather than drained. During rainfall, water is slowed down through water retention and corralled into areas used as parks during dry seasons. The retained water is then channeled into canals and ponds that will help sustain wildlife, improve soil quality, and increase safety levels in case of flooding. Water will flow year round, ultimately maintaining the stability of soils and the general health of the city’s eco-system. [beforeafter][/beforeafter] Nowadays, water-management is a particularly important issue as the world is looking for ways to appease and manage the impacts of climate change and increased human activity. Louisiana is currently experiencing the highest rates of sea-level rise, making the ‘Big Easy’ highly vulnerable to damages caused by intense downpours. The $6.2 billion plan would help mitigate flooding during heavy rainfalls, and repair soils that have been dried up by the previous flood management system, hence preventing further sinking of the ground under sea level. Refurbishing centuries’ old infrastructures will be challenging and it still remains unclear how the plan will be funded. The project’s estimated competition date is 2050. City officials believe that it would be effective in mitigating the risks induced by floods and will bolster the appeal of acquiring local real estate.The Urban Water Plan re-envisions New Orleans as a vibrant metropolis of ponds and canals. The core idea is to efficiently manage water, instead of trying to get rid of it. If successful, the plan will transform the city into an urban landscape filled with rain gardens and bioswales, create appealing waterfront properties, and promote home values. New Orleans is on the right track to becoming a potential leader in water management and a potential model for other cities around the world.
