From Alps to Atlantic (6) Lacq

Some years ago, while in Paris, I had a chance to listen to a speech by Jean Paul Lacaze, a French urban planner among those that had been everywhere in all the relevant places, as he explained a curious story. He talked about the French experience with new towns, and the growing complexity of the criteria to choose a place (to erect a city, an industrial area or whatever) in consistency with the sustainable development paradigm. He spoke about the urban planning project linked to the Lacq gas field, in Pyrénées Atlantiques. The field was discovered in 1951 and is somehow the origin of the present Total oil group; there are some parallels with the current shale gas, as it was a hard to obtain resource (high proportion of hydrogen and sulphur), but a relevant input for the national economy. Lacaze said that while the presentation of the project to the press around 1957, the mayor said something like “we chose the better place, no doubt; Jean Paul and I, we drove for an entire day on my car around the municipality to find it”. That is a far cry from what could be considered good practice now, but it is how Mourenx, a city of 7.000 now (10.000 in 1968) appeared.

The gas field closed in 2013, and the economic base of the city suffered, as in many other mining areas, even if there is a set of industrial projects. The city seems clearly a “ville nouvelle” of the first model, even a hybrid with the previous “grand ensemble” model. It is an architecture of lineal multi-storey blocks on a rather regular street grid in which every chance is taken to introduce a curve (and the terrain gives some room for that).

That day, Jean Paul and the mayor chose a relatively flat area surrounded by two large sets of hills giving a certain visual protection when seen from the close industrial areas. Each neighbourhood has a tower, but individual homes have become more important (after all, that is France). The Plan Local d’Urbanisme is being revised, with moderate growth previsions.
