Replacement Dwelling, Neds Lane, Stalmine-With-Staynall, Poulton-Le-Fylde, Lancashire, FY6

Given the sensitive nature of the development (residential) and the history of the site a contaminated land planning condition was attached to the decision notice for the proposed development.

The first stage of discharging the condition was to prepare a Phase I desk study report in order to determine if the site has the potential to be impacted by elevated levels of contamination, and to determine the source as well as the likelihood of the risk occurring.

A desk study determines what issues relating to historical contamination may affect the site, this is undertaken by reviewing the site history using a combination of O.S. maps, aerial, plates and street level imagery, a review of data held by regulatory bodies (Environment Agency, local authority, BGS etc.) as well as a site walkover survey.

The history of the site and surrounds were researched using a combination of Ordnance Survey (O.S.) maps, street level imagery and aerial plates, this revealed the site was developed circa 1951 when the site was occupied by Ash Grove. The 2000 aerial plate identified a dwelling on the south western boundary.

A number of ponds were noted within 250m of the site, the closest being 50m from the site, the majority had been in-filled.

Street level imagery confirmed the building on the site was a single storey dwelling.

The planning history of the site was reviewed as part of the desk-based research and the reports associated with any previous application and the subject were located and studied, no salient information was obtained

The published geological maps identified the site as being underlain by Devensian Till, which in turn was underlain by the Singleton Mudstone formation. As no publicly available boreholes for the areas were available from the BGS no further information ion ground conditions could be obtained.

Data provided by regulatory bodies confirmed the presence of a number of ponds within 250m.

On completion of the desk based research a site reconnaissance visit was undertaken, at the time of the walkover survey the dwelling had been demolished with the demolition rubble present on the site.

Once the walkover survey was completed a qualitative risk assessment was undertaken on the potential sources of contamination identified in the desk study report in order to determine if any warranted further investigation, this concluded that the risk posed by the potential sources of contamination identified in the report were sufficiently low to not warrant further assessment and a watching brief was proposed.

The report was submitted to discharge the condition (18/00094/DIS), the proposals were accepted and subject to a watching brief being submitted on completion of the development.
