Sintesi Omnilex

The challenge concerned a building authorization on a parcel classified in noise sensitivity degree II. The court held that, because the relevant limit values for DS II would be exceeded, the authority had to require a noise forecast under environmental law. The permit was nonetheless confirmed, but only after a remediation plan is established in advance.

Massima Omnilex

Art. 25 al. 1 LPE; art. 36 OPB; noise forecast in case of exceedance of sensitivity-degree threshold values: where a parcel is assigned to sensitivity degree II and the applicable limit values are likely to be exceeded, the permit authority must require an acoustical forecast before deciding on the construction application. The permit may be maintained if the situation is addressed by prior remediation or assainissement measures; the authority must not dispense with the forecast merely because the project is otherwise admissible.

Résumé

Dès lors que la parcelle des recourants est soumise au degré de sensibilité II et que les valeurs correspondant au DS II seront dépassées, le département devait exiger un pronostic de bruit (art. 25 al. 1 LPE, art. 36 OPB). L'autorisation de construire doit être confirmée, moyennant l'établissement préalable d'un plan d'assainissement.
