The restored stretch of Rio Tepice in the urban area of Chieri

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)throught these kind of actions: - restoration (cutting, new plantations with autoctonous species, bioengeneering works)of the riparian vegetation and of the river banks; - revegetation of an area of 1.08 hectare previously occupied by a manufacturing; - creation of new footpaths adjacent to the watercourse
