The difficult puzzle to expand El Prat

Any answer that entails a bodily growth of El Prat airport, both with a fourth runway over the ocean or with an extension of the third runway on land, would require the declassification of the protected pure areas that may be affected and an specific authorization from the group authorities to hold it out, in addition to cowl the technical and air security necessities vital to advertise long-haul flights.

The difficult puzzle to expand El Prat

Any answer that entails a bodily growth of El Prat airport, both with a fourth runway over the ocean or with an extension of the third runway on land, would require the declassification of the protected pure areas that may be affected and an specific authorization from the group authorities to hold it out, in addition to cowl the technical and air security necessities vital to advertise long-haul flights. These two routes have an effect on areas of particular safety for birds (ZEPA); They're enclaves built-in into the European Natura 2000 community; and, due to this fact, a modification or discount of its limits would require the sunshine of the EU. Be that as it might, the way forward for the airport relies upon, within the occasion that it bets on its growth, on a political settlement that must contemplate each the aforementioned environmental situations and people referring to airport operations. On the backside of the talk on El Prat is the mannequin of financial and social improvement that's chosen for Barcelona and Catalonia. Ecologists, environmental specialists and engineers analyze the principle options which have targeted the general public debate so far, with their professionals and cons.

The marine possibility enters the fray for the primary time

in favor of learning it

The environmentalist Claudio Racionero stresses that "the choice of a marine growth deserves to be studied and shouldn't be dominated out from the outset", though he recollects that this area is a part of the Natura 2000 Community of European protected areas (it's a particular safety space for birds, ZEPA). Subsequently, its environmental viability "will depend upon detailed research" of the affect on the coastal migratory hall and within the marine feeding space of ​​sure nesting birds within the delta. “In any case, it's essential to make clear how these compensatory measures are adopted, and if all this may be executed at sea. It's a political query, ”he sums up. Racionero factors out that gaining floor from the ocean is already what the port did by advancing 1.5 km offshore. Different specialists level out that the seabed on which the third observe within the sea would settle is muddy and sandy, with banal fauna. There are not any meadows of phanerogamous vegetation (Posidonia oceanica or Cymodocea nodosa ) within the space, which needs to be protected. The proposal foresees masking the concrete pylons with carbonated and porous materials, which might facilitate the set up of organisms typical of the coral shields.

The questions of rising up within the sea

A path with opposition

Lluís Toldrà, environmental lawyer and Depana companion, is satisfied that the proposed answer (pylons on the seabed) is "technically, economically and geologically unfeasible", because the delta space is affected by subsidence (compaction and collapse of the river sediments). The ornithologist Pep Arcos believes that the impact of a runway of those traits on seabirds "could possibly be necessary, since in your entire mouth of the Llobregat there's a combination of waters of a sure productiveness and that draws terns or gulls, together with susceptible species." , reminiscent of Audouin's gull or the Balearic shearwater, in important hazard”.

Fourth observe of three,400 meters

Elevated capability, however technical limitations

Constructing a brand new runway over the ocean, as proposed by a gaggle of engineers and economists led by Joaquim Coello and Andreu Mas-Colell, would clear up the present operational issues. Planes of any measurement might land and take off at El Prat and it could even permit for a rise within the 90 operations per hour that the airport aspires to get well. Nonetheless, it could result in different issues, feedback César Trapote, professor on the Castelldefels-UPC College of Telecommunications and Aerospace Engineering. One of many fundamental ones, the taking pictures time. That's, how lengthy it takes for the airplane to cowl the space from when the passengers board till the plane reaches the top of the takeoff runway. With a observe over the ocean one mile from the coast, this time would improve significantly, which might additionally have an effect on the remainder of the operation. "Any change that's carried out on the airport should serve to make it extra aggressive, and growing the taxi time is much less engaging for airways, particularly if we need to promote people who function long-haul flights, to settle there," argues Trapote. .

Extension of the observe to the north (La Ricarda)

Slaughter with environmental compensations

The ornithologist and naturalist Jordi Sargatal endorses the thought of ​​extending the third observe in the direction of La Ricarda. "To the touch Ricarda a bit, however with out destroying it," he says. He proposes extending the third observe, however affecting solely "Ricarda, and never touching Remolar (to the south), as a result of Ricarda is worse ecologically than Remolar." His concept is that this doable motion ought to serve to attain an ecological restoration of Ricarda (enhancing its water flows). "It's essential to make an ecological enchancment, however not ornithological, as a result of if there are extra birds, they must be scared in order that there can be no affect with the planes." He argues that "lengthening the runway just a little doesn't essentially imply extending the concrete runway, however moderately growing the world of ​​the operational a part of plane, the clear half and the half with beacons". All this have to be compensated with a brand new inland wetland, in Viladecans, for migratory birds within the Llobregat delta, "as a result of Europe asks us to optimize the administration of pure areas."

floor extension

Prolong the third runway by 500 meters or 350 meters is sufficient?

“Extending the third runway by 500 meters can be the naked minimal so that enormous planes –people who fly distances higher than 7,000 kilometers– can take off from it in any environmental situation. It will even be extra operative to increase the runway by 800 meters and function impartial runways” says Trapote. This feature "would make airport operations extra strong." In accordance with his evaluation, an extension of 350 meters "wouldn't utterly clear up the operational issues as a result of the lengthy runway can be vital for some heavy takeoffs, however it's higher tailored to suit the gaps." The professor of Transport on the UPC, Francesc Robusté, for his half, defends a minor extension, "of between 200 and 300 meters" distributed to the east and west, additional optimizing operations, encouraging the return of a part of the low value flights to Reus and Girona with an excellent tariff and connection coverage with Barcelona. This, he maintains, would permit the airport to be decongested and solely a small a part of the long-haul flights would want to make use of the internal runway. It will require constructing a brand new satellite tv for pc terminal "and a major funding by Aena to soundproof houses in neighboring cities", thus mitigating the acoustic affect.

Environmental offsets on land, the place?

authorized downside

The land extension of the present observe in the direction of Remolar or Ricarda clashes with the truth that these are "partial pure reserves protected by the Regulation of Pure Areas of Catalonia", based on Claudio Racionero. As well as, they're protected by the EU as areas for birds (ZEPA). The growth of the airport in these reserves "can't be executed as a result of it presents severe, insurmountable authorized issues," says Toldrà, Depana's lawyer. The dearth of safety and declassification of those areas for birds with the specific authorization of the European establishments is "unimaginable", based on Toldrà, since "the compensatory measures agreed upon within the earlier enlargement (20 years in the past), included within the declaration of environmental affect and promised to the EU”. For that reason, confronted with this requirement, the Generalitat promotes an growth of the ZEPAs within the space, promised by the EU however not but authorised. Supporters of this extension haven't specified the place these environmental compensations would happen, bearing in mind that they need to not overlap with people who the Generalitat has already promised in its response to the EU file.
