Erection of a Replacement Dwelling, The Smithy, Grafton, Shrewsbury, Shropshire

Case Study Reference: 14-04-03

Planning Authority: Shropshire Council

Planning Reference: 13/03382/FUL and 14/01023/DIS

Synopsis:

In order to discharge the contaminated land planning condition attached to the decision notice Demeter Environmental were commissioned to prepare a desk study report for the site.

The review of the site history revealed the site was formerly a Smithy which was present prior to the first edition Ordnance Survey map from 1871, a number of parcels of in-filled land were identified on the historical maps within 250m of the site.

A number of buildings as well as gravel made ground was identified during the walkover survey. Whilst the off site potential sources of contamination were discounted as credible sources as part of the qualitative risk assessment, the made ground on the site and the former smithy were credible sources and an intrusive Phase II investigation was required to fully assess the ground conditions  and the risk to the end users.

The Phase II investigation was undertaken in April 2014 and comprised of the excavation of fifteen trial pits across the site. Made ground was identified in an area around trial pit TP109, which chemical analysis indicated was impacted y elevated levels of contamination, and the report recommended that the made ground was removed from garden and landscaped areas.

Copies of the Phase I and Phase II report can be accessed via the Shropshire Council planning portal. The memo accepting the reports and partially discharging the contaminated land planning condition can be accessed here.
