Native title of the NBS intervention
Renforcement des rives du Janon
Short description of the intervention
This intervention is about the restoration of the riverbanks of the Janon River along a street in the Terrenoire District of Saint Etienne. This area was abandoned for more than 10 years, without maintenance and cleaning. Therefore, this intervention was mandatory for clean up to avoid flood as well as bringing back vegetation and offering some quality walking areas for citizens (Ref. 1).

According to the article (Ref. 1), the rehabilitation works of the riverbanks took place for about a month and half.
Goals of the intervention
"Reinforcement of the banks which will be vegetated by a lawn and shrubs" (Ref. 1)
"The bed of the stream, clogged with a lot of waste, prevented the Janon from flowing normally. The work carried out today will revive it and also aim at the recovery of the banks." (Ref. 1)
"Its restored functioning will make it a place of relaxation and of walk and offer a framework in safety to the residents who remain on the adjacent bank side west." (Ref. 1)
Quantitative targets
" a budget of approximately 55,000 euros" (Ref. 1).
Monitoring indicators defined
Cost of works in EUR (Ref. 1).

Implementation activities
"Complete cleaning of the area, and a reinforcement of the banks which will be vegetated by a lawn and shrubs and equipped with furniture of relaxation." (Ref. 1).
"The banks collapsed, especially those bordering the dwellings, which presented serious major risks for the latter, with the appearance of very significant deterioration. The bed of the stream had become an open dump, filled with earthworks and all kinds of waste presenting the risk of flooding or accidents of all kinds. It was also invaded by a particularly polluting Japanese reed hedge vegetation" (Ref. 1).
-"Its restored operation will make it a place to relax and walk and provide a safe environment for residents who live on the adjacent shore on the west side" (Ref. 1).
-"The bank, on the rue du Carcaret side, was occupied in an unauthorized manner by “worker” -type gardens whose occupants were relocated, after consultation with the Volpette-La Châtaigneraie gardens for the most part (less than ten)" (Ref. 1).

Description of environmental benefits
Environmental quality:
-Improved waste management: "The bed of the stream had become an open dump, filled with earthworks and all kinds of waste presenting the risk of flooding or accidents of all kinds" (Ref. 1). This was cleaned through the NBS (Ref. 1).

Water management and blue areas:
-Improved water quality: "At present, a complete cleaning of the area has been carried out with depollution, and a strengthening of the banks" (Ref. 1).
-Increased protection against flooding: the banks which had previously collapsed were strengthened and the river returned to a controlled flow on its original riverbed (Ref. 1).
-Enhanced protection and restoration of freshwater ecosystems: "Thus the Janon will find its original bed with a controlled flow" (Ref. 1).

Green space and habitat:
-Prevent or control invasive alien species: a "particularly polluting Japanese reed hedge vegetation" was cleared in this NBS (Ref. 1).
