| Conditions / Reason for Refusal: |
01
Prior to the commencement of the development an assessment of all significant noise sources likely to affect the proposed development including noise from the busy town centre, activities in the ground floor retail premises and fixed plant in the area shall be carried out by a suitably competent person and be submitted in writing to the Local Planning Authority for approval. The report shall:
a) Determine the existing noise climate.
b) Include raw data in table format in the appendices.
c) Predict the noise climate bedrooms and other habitable rooms of the development (daytime & night-time).
d) Detail the proposed attenuation/design necessary to protect the amenity of the occupants of the new residences.
If the noise attenuation measures include windows being kept closed, then details of alternative ventilation over background ventilation will be required. If noise levels are such that mitigation is necessary, good acoustic design in terms of orientation of buildings and the positioning of non-habitable rooms on noisy facades is a preferable method of mitigation. The following noise criteria as detailed in BS8233:2014, needs to be achieved:
a) The 16-hour LAeq shall not exceed 35dB between 0700 and 2300 hours when measured inside any noise sensitive rooms in the development.
b) The 8-hour LAeq shall not exceed 30dB between 2300 and 0700 hours when measured inside any bedroom in the development.
c) The 15-minute LAF1 shall not exceed 45 dB between 2300 and 0700hrs when measured inside any bedroom in the development.
Fixed plant shall be assessed in accordance with the criteria set out in BS4142:2014+A1:2019.
The approved mitigation measures shall be implemented prior to the first occupation of each dwelling.
Note: All noise assessments should be carried out by a competent person. Developers may wish to contact the Association of Noise Consultants http://www.association-of-noise-consultants.co.uk/ (020 8253 4518) or the Institute of Acoustics http://www.ioa.org.uk (0300 999 9675) for a list of members.
Reason
To safeguard the amenities of the occupiers of the proposed development in accordance with RMBC Policy SP52 and parts 12 and 15 of the NPPF.
Informative(s)
The applicant is reminded to apply for any necessary Building Regulations and if necessary HMO Licensing (through the Council’s Environmental Health department) that may be required prior to the conversion which are considered under separate legislation. The applicant should liaise with Environmental Health and Building Control to ensure that the internal layout meets the required Regulations.
