All the chatter may be around Frank Gehry and the Los Angeles River, but that waterway is not the only channelized river on the West Coast. More than 40 years ago a 10.5-mile long stretch of the Tijuana River was concretized as a flood control channel to make more development possible. If Gehry’s scheme is all about hydrology, a new proposal for the Tijuana River is about electricity. René Peralta and Jim Bliesner’s scheme for an energy farm combines large arrays of solar panels with an algae system to remediate the water headed for the Tijuana River Estuary and the Pacific Ocean. According to Peralta, the system would produce enough megawatts to power 30,000 homes or a 112-acre industrial park. The plan came out of a class developed as part of UC San Diego Urban Studies and Planning Program, where both men teach. Additionally Peralta directs Woodbury University’s Landscape + Urbanism Master of Science program and Bliesner leads the nonprofit Center for Urban Economics and Design. While generating power is important, the pair see overall regional sustainability as critical goals. According to a story in the San Diego Union-Tribune, they’ve presented their work at the environmental conference Green Tijuana-San Diego Verde and have spoken to North American Development Bank. Their preliminary analysis suggests that the solar panels could help decrease the current heat island effect impacting Tijuana’s dense urban neighborhoods by lessening solar radiation in the summer. They also proposed a partially roofed section of the river to create shade over the brutal concrete channel. Other potential infrastructural upgrades would include tree grids on top of the canal and floating algae pools that would sequester CO2 levels generated by vehicle emissions (the canal is flanked by roadways). Although the project is in preliminary stages and still needs governmental support, it offers a much needed “hack” in the face of ecological and social costs in Mexico. Or as Peralta told Sandra Dibble of the Union-Tribune, “[Tijuana] does not have the luxury of reinventing the river to what it once was.” He noted that the solution comes from “hybridizing its old infrastructure with new technologies.” It’s about teaching an old channel some new tricks.

Despite a smattering of gray skies, Chicago inaugurated another stretch of its revamped riverwalk this Memorial Day weekend, and visitors were eager to explore the newly expanded public space. Kayakers, pedestrians, locals and tourists alike came to check out the partially opened project, which will remain under construction through the summer. Along with Ross Barney Architects, Benesch, and Jacobs Ryan and the Chicago Department of Transportation, Sasaki Associates led design on the project—a major component of Mayor Rahm Emanuel's bid to rebrand the Chicago River as the city's “second shoreline.” Work began in 2013, and many of the storefronts built along the riverwalk's newest section—from State Street to Clark Street—still await tenants. Construction work continued right up until opening day.

In keeping with Paris’ mounting aversion to automobiles, Mayor Anne Hidalgo recently announced plans to bar motorists from the banks of the River Seine by summer 2016. This latest blow to motorists occurs in tandem with the all-or-nothing anti-pollution target Hidalgo set last year of banning all non-electric or hybrid vehicles from Paris’ most polluted streets by 2020. Renderings for the futuristic River Seine project a motor-free parkland consisting of a tree-shaded promenade with space for children’s playgrounds and sports facilities. The length of this promenade is TBD, with some proposals occupying a modest 0.9 miles, while others insist on a 2.05-mile car-free quayside, potentially freeing up 1.4 acres of parkland. “All of this is part of a comprehensive policy in which we assume very deliberately that there will be fewer cars in Paris,” Hidalgo told reporters at a press conference. “Therefore, in calculating the flow of spillover traffic I don’t project myself into a world where there are as many cars as today. Objectively, that will no longer be the case.” The Seine has a distinctive double-tiered embankment that has allowed it to moonlight as a motorists’ artery into the city center without detracting from the romance of the riverscape. The upper embankment sits at street level, and has remained a scenic promenade dotted with quaint booksellers’ stalls. The lower embankment, where the roads traverse, is at water level and is sunken below high walls, with sections of road encased in tunnels. The City of Paris began reclaiming the Seine in 2002 under the "Paris Plages" program, when it closed down sections of the quayside to create a temporary summer beach complete with real sand and sun loungers. In 2013, the city barred cars permanently from a long stretch of the Left Bank to create a waterside park. According to the mayor, the city’s slow assail on motorways is part of “an urban, almost philosophical project which consists of seeing the city in another way than through the use of cars.” In Hidalgo's car-cutting schemes along the Seine are also architected toward freeing up the Georges Pompidou Highway on the North side, part of a UNESCO World Heritage Site.
We’ve been collecting dribs and drabs about the next phase of development along the already booming Los Angeles River, and the next is that the LA River Revitalization Corporation—the non-profit created to oversee development around the changing waterway—is hoping to put together a dream team of architects and planners to do something ambitious. The group won’t comment on the specifics (though their last board meeting did discuss “projects, infrastructure, and investment, according to the agenda), but we’re very curious to learn more about this.
