Air Quality Assessment – Solent Retail Park, Havant


REC provided air quality consultancy services in support of the planning application for an extension to Solent Retail Park, Havant, Hampshire. The proposals entail the redevelopment of a plot of land which currently consists of industrial and commercial units into approximately 4,500m2 of retail floor space.

Pre-application consultation with Havant Borough Council indicated that air quality in the vicinity of the site was poor and deteriorating. As such, the council raised concerns about additional pollution and traffic congestion resulting from the proposed development.

An Air Quality Assessment was therefore necessary to determine the potential impact on local amenity levels as a result of the scheme. Furthermore, the scope of works included the identification of suitable mitigation techniques to control the effects of the development to an acceptable level.

REC was commissioned for the project and undertook a detailed dispersion modelling study using ADMS-Roads. Our Air Quality Assessment performed the following functions:

  • Quantification of pollutant concentrations at sensitive locations near the site.
  • Prediction of impacts resulting from emissions associated with additional traffic generated by the development.

Based on our dispersion model, we determined that the potential impacts on pollutant levels as a result of traffic generated by the development would not be significant at any sensitive location in the vicinity of the site.

We concluded that air quality issues were not considered to be a constraint to planning consent and that no mitigation measures would be necessary. Consequently, REC’s Air Quality Assessment resulted in the development proceeding as originally proposed whilst ensuring the protection of local residents.
