Multi-disciplinary Technical Services – Pocklington

26.09.17

REC was commissioned to undertake multi-disciplinary technical services in support of a planning application for the proposed Phase 4 residential scheme at Pocklington, East Yorkshire. The proposals comprised the development of the site to provide up to 100 residential dwellings and associated infrastructure.

REC produced the following technical reports for the scheme:

  • Air Quality Assessment;
  • Construction Environmental Management Plan (CEMP);
  • Artificial Lighting Impact Assessment; and
  • Noise Impact Assessment.

Air Quality Assessment

Due to the size of the proposals, the development had the potential to cause air quality impacts at sensitive locations as a result of road vehicle exhaust emissions from additional traffic generated by the development. In addition, the development had the potential to introduce future residents into an area of poor air quality. An Air Quality Assessment was therefore conducted in order to quantify pollutant levels across the site, consider location suitability for residential use and provide consideration of potential effects as a result of the proposals.

Dispersion modelling was undertaken in order to quantify pollutant concentrations at the site. This indicated that pollutant concentrations were not predicted to exceed the Air Quality Objectives at sensitive locations across the site. The assessment also concluded that air quality impacts as a result of the traffic generated by the development were not predicted to be significant.

Based on the assessment results, air quality issues were not considered a constraint to planning consent for the proposed development.

Construction Environmental Management Plan

The site is located to the north-east of an area which has recently been developed for residential use. As such, potential dust impacts at existing sensitive receptors during the construction phase of the development were a particular concern. A CEMP was therefore produced in order to identify where impacts are likely to occur and present mitigation measures to control fugitive dust releases beyond the site boundary as a result of on-site construction activities.

Artificial Lighting Impact Assessment

Artificial lighting from floodlights associated with an adjacent amenity centre had the potential to impact on future residents at the proposed site. As such, an Artificial Lighting Assessment was undertaken as part of the planning application.

Baseline conditions were defined through a site survey and sensitive receptor locations within the development were identified, including general landscape considerations. A computer model of the development was also produced using lighting engineer software which enabled proposed building layouts to be considered in relation to existing floodlighting and any negative impacts therein.

Based on the assessment results, it was concluded that existing floodlighting would not cause unacceptable light spillage at the future residential dwellings and as such, lighting impacts from the adjacent amenity centre was considered to be within acceptable limits.

Noise Impact Assessment

Due to the proximity of the Henry Thirsk Amenity Centre and The Balk, noise had the potential to impact upon the proposed amenity of the development both externally and internally. Accordingly, REC undertook attended and unattended sound measurements of road traffic, the use of the pitches and to quantify the existing levels of background sound prevalent across the Site.

The Acoustics Team utilised the noise modelling software; SoundPlan, in order to accurately predict the passage of road traffic sound across the Site, within gardens and incident upon the facades. Hand calculations were used for the Henry Thirsk Amenity Centre.

Accordingly appropriate recommendations on site design and potential mitigation measures were specified in order to reduce these impacts for both external and internal habitable areas. Specifically, the assessment recommended that garden areas be located behind dwellings so that the building envelopes front on to the noise source to act as an effective barrier to the noise.  Acoustic Barriers would also need to be utilised at various positions. Furthermore, REC advised that an alternative ventilation scheme may be required for certain habitable rooms.

Based on the assessment, it was determined that noise need not be a constraining factor in the determination of the application and should be considered at the detailed planning stage when considering a suitable layout/masterplan.
