Agenda item

The architectural illumination, as part of the Illuminated River proposal, of Waterloo Bridge (Application 1), Golden Jubilee Bridge (Application 2), Westminster Bridge (Application 3), Lambeth Bridge (Application 4), Vauxhall Bridge (Application 5), Grosvenor Bridge (Application 6) and Chelsea Bridge (Application 7) including the installation of fixtures, fittings and ancillary equipment and associated works.

The presenting officer tabled the following amendments to the draft decision letters:

Additional conditions

The illuminated displays hereby approved must not include corporate sponsorship or any form of advertising.

Condition 6

(1)      Where noise emitted from the proposed plant and machinery will not contain tones or will not be intermittent, the 'A' weighted sound pressure level from the plant and machinery (including non-emergency auxiliary plant and generators) hereby permitted, when operating at its noisiest, shall not at any time exceed a value of 10 dB below the minimum external background noise, at a point 1 metre outside any window of any residential and other noise sensitive property, unless and until a fixed maximum noise level is approved by the City Council. The background level should be expressed in terms of the lowest LA90, 15 mins during the proposed hours of operation. The plant-specific noise level should be expressed as LAeqTm, and shall be representative of the plant operating at its maximum.

(2)      Where noise emitted from the proposed plant and machinery will contain tones or will be intermittent, the 'A' weighted sound pressure level from the plant and machinery (including non-emergency auxiliary plant and generators) hereby permitted, when operating at its noisiest, shall not at any time exceed a value of 15 dB below the minimum external background noise, at a point 1 metre outside any window of any residential and other noise sensitive property, unless and until a fixed maximum noise level is approved by the City Council. The background level should be expressed in terms of the lowest LA90, 15 mins during the proposed hours of operation. The plant-specific noise level should be expressed as LAeqTm, and shall be representative of the plant operating at its maximum.

(3)      Following installation of the plant and equipment, you may apply in writing to the City Council for a fixed maximum noise level to be approved. This is to be done by submitting a further noise report confirming previous details and subsequent measurement data of the installed plant, including a proposed fixed noise level for approval by the City Council. Your submission of a noise report must include:

(a)            A schedule of all plant and equipment that formed part of this application;

          (b)      Locations of the plant and machinery and associated: ducting; attenuation and damping equipment;

          (c)      Manufacturer specifications of sound emissions in octave or third                        octave detail;

          (d)      The location of most affected noise sensitive receptor location and the                 most affected window of it;

          (e)      Distances between plant & equipment and receptor location/s and any mitigating features that may attenuate the sound level received at the most affected receptor location;

          (f)       Measurements of existing LA90, 15 mins levels recorded one metre outside and in front of the window referred to in (d) above (or a suitable representative position), at times when background noise is at its lowest during hours when the plant and equipment will operate. This acoustic survey to be conducted in conformity to BS 7445 in respect of measurement methodology and procedures;

          (g)      The lowest existing L A90, 15 mins measurement recorded under (f)                   above;

          (h)      Measurement evidence and any calculations demonstrating that plant and equipment complies with the planning condition;

          (i)       The proposed maximum noise level to be emitted by the plant and equipment.
