Project summary

Edit project overview to modify the project summary.


This project concerned the restoration of a stretch of Rio Tepice in the urban area of Chieri (TO) through this kind of actions:

  • restoration (cutting, new plantations with autochthonous species, bioengineering works) of the riparian vegetation and of the river banks;
  • revegetation of an area of 1.08 hectares;

Moreover new footpaths adjacent to the watercourse were created.
