The combined expected maximum traffic noise level from the proposed road scheme together
with other traffic in the vicinity (i.e. Do Something scenario) is greater than 60dB Lden at all
twenty-five of the locations assessed.
The Do Something levels for twenty-one of these locations is less than or equal to the
predicted Do Nothing levels. Therefore Condition (b) of the Design Goals (refer to Section
8.1.3) is not satisfied and no mitigation measures are required at these locations.
Mitigation measures will be required for the remaining four locations (i.e. R03, R04, R05 and
R06).
Year 2025
The combined expected maximum traffic noise level from the proposed road scheme together
with other traffic in the vicinity (i.e. Do Something scenario) is greater than 60dB Lden at all
twenty-five of the locations assessed.
The Do Something levels for twenty of these locations is less than or equal to the predicted
Do Nothing levels. Therefore Condition (b) of the Design Goals (refer to Section 8.1.3) is not
satisfied and no mitigation measures are required at these locations.
Mitigation measures will be required for the remaining five locations (i.e. R03, R04, R05, R06
and R07).
Planning Reference SD04A/0233
It is noted that planning permission has been granted for a residential development between
receptor location No. 18 and the mainline. The proposed development has been included in
the model and the assessment indicates that there is no requirement for mitigation at this
location.
Newlands Golf Club
The proposed route runs along the northern boundary of the Newlands Golf Club. The NRA
Guidelines typically call for mitigation measures to be considered solely in relation to long
term residential locations. However due to the high amenity value of the club, detailed
considered has been given to it during the design stage of the proposed route.
The following measures have been incorporated into the development in order to minimise
any potential noise impact of the route on the park:
• a 2m stone wall is proposed along the eastern and northern boundaries of the golf club
ground;
• a 2m berm to be planted with mature trees is proposed along the eastern and northern
boundaries of the golf club grounds.
The noise environment will also benefit from the low-noise surface along the mainline of the
scheme.
