Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-4b3c3fbe819c6167 quantitative
laid out in September 2016 inside the perimeter of Badajoz, Pallars, Llacuna and Tànger
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city's own page on the superblock dates and locates it: "El setembre del 2016 es va crear la Superilla del Poblenou en el perímetre format pels carrers Badajoz, Pallars, Llacuna i Tànger, a cavall entre els barris del Poblenou i del Parc i la Llacuna del Poblenou."

Claim 2 clm-73f3ac284477c884 quantitative
the city had tested the idea in Gràcia back in 2003
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Guardian traces the lineage: "The superblocks idea was first outlined in 1987, after noise mapping revealed that levels were too high, and the first superblock was tested in 2003 in Gràcia."
Caveat

Claim 3 clm-41c8c38cdb9a9e75 descriptive
trialled with painted road markings, movable furniture and trees in containers
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The prize archive lists the tactical materials one by one: "the reversible application of signs painted on the ground, the temporary installation of elements of street furniture, and placement of trees planted in mobile containers." The city says the same: "es va actuar amb pintura, mobiliari urbà i arbres en torreta."

Claim 4 clm-689de0fc22ea7dc9 descriptive
at a tenth of what conventional works would have cost
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The archive states the cost ratio directly: the provisional solutions "cut expenditures to one tenth of what a conventional project would have cost".
Caveat
This is a comparison with an unbuilt alternative rather than a measured saving: no listed source gives the cost of either the tactical phase or the permanent works.

Claim 5 clm-cb2578412668e248 quantitative
then consolidated in concrete from autumn 2017
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The archive dates the second phase: "the second phase, initiated in autumn 2017, has consisted in consolidating the intervention on a permanent basis by means of conventional civil engineering work." The city describes the same works starting "a la tardor de 2017".
Caveat
Both sources date the start of the permanent works; neither states when they finished.

Claim 6 clm-74c9a21aaeb32b4b quantitative
Traffic on inner streets fell 58%
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The archive reports the measurement: "Although traffic in the four roads around the perimeter has increased by 2.6%, the number of vehicles circulating in the inner streets has dropped by 58%."
Caveat
The figures are the city's own evaluation as reported by the prize archive, which did not measure them itself; no listed source gives the measurement period or the baseline.

Claim 9 clm-29b69bc68fba3627 descriptive
daytime noise fell about five decibels
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The archive reports it against the earlier state: "In these streets which once exceeded the WHO's noise exposure limits, daytime noise levels have dropped by an average of five decibels."
Caveat
The five decibels are an average across the inner streets, which the source says had previously exceeded the WHO exposure limits.

What the mapping says
The archive counts both: "More than three hundred benches have been installed, 212 new trees planted, and open-air cultural activities have multiplied."

The pilot drew a media storm and sustained protest within days of the first phase
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The archive records the reaction rather than smoothing it over: "A few days after the first phase was implemented, a media storm was whipped up. This was an unprecedented phenomenon in Barcelona's urban planning in recent decades. A not inconsiderable number of local residents and businesspeople started a wave of continuous vociferous protests."

was adjusted through a residents' working group rather than abandoned
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The city describes the mechanism and its result: an assessment process open to the neighbourhood "amb la creació d'una Comissió de Treball amb els principals col·lectius i entitats", and "Fruit d'haver escoltat les queixes i les propostes, i de la feina feta en el marc de la Comissió de Treball, es va implantar la mobilitat definitiva a principis de 2017".

The city's own page on the Poblenou superblock: the September 2016 perimeter, the temporary and reversible first phase, the residents' working group that reshaped it, and the permanent works from autumn 2017. It carries no measurements.

Open the recorded source note

Published four months before the Poblenou pilot opened, so it describes the programme rather than this superblock. Source for the lineage: the idea was outlined in 1987 and first tested in Gràcia in 2003.

Open the recorded source note

The prize archive of the CCCB, and the only source in this entry that carries the measurements: 13,350 m² of pedestrian space gained, 58% less traffic on the inner streets against 2.6% more on the perimeter, five decibels less daytime noise, 212 trees and more than 300 benches. It also records the media storm and the resident protests that followed the first phase. The figures are the city's own evaluation, reported here rather than measured here.

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
