(Environmental Protection Act, EPA)

¹ New build­ing zones in­ten­ded for res­id­en­tial build­ings or for oth­er build­ings in­ten­ded as long-stay ac­com­mod­a­tion may be planned only in areas where am­bi­ent noise levels do not ex­ceed the plan­ning val­ues or in areas where these val­ues can be met by the ap­plic­a­tion of plan­ning, design or struc­tur­al meas­ures. The rezon­ing of build­ing zones does not con­sti­tute the defin­i­tion of new build­ing zones.³¹

² If the plan­ning val­ues are ex­ceeded in an ex­ist­ing but as yet un­developed build­ing zone in­ten­ded for res­id­en­tial build­ings or oth­er build­ings in­ten­ded as long-stay ac­com­mod­a­tion, it must be real­loc­ated for a use that is less sens­it­ive to noise, un­less the plan­ning val­ues can be met in the great­er part of the area by the ap­plic­a­tion of plan­ning, design or struc­tur­al meas­ures.
