Erection of a Detached Dwelling, Whittle-Le-Woods, Chorley
Case Study Reference: 10-11-05
Planning Authority: Chorley Council
A contaminated land planning condition was attached to the decision notice due to the sensitive nature of the development and Demeter Environmental were commissioned to prepare a desk study report for the site.
The site appears to be open land from the first edition O.S map until 1962 when the site appears to be developed (a small building is present on the eastern corner of the site). This building is not present on the 2010 map.
Initially, the site boundaries are formed by Hardacre Farm to the south and open land on all other sides. By 1962 the eastern boundary is formed by a dwelling. No significant changes to the northern or western boundary were observed.
A number of ponds were identified on the 1893 map, 190m north east (in-filled circa 1962), three
180m east (in-filled between 1911 and 1962), 20m east (in-filled circa 1911), 230m south (in-filled circa 1962). A pond 100m north is identified on the 1962 map, which is still present on the 2010 map.
During the walkover survey it was observed that the site was open land and formed part of the garden of Hardacre barn.
As part of the walkover survey, a number of hand held boreholes were sunk and the absence of made ground on the site was demonstrated.
Whilst there was no potential sources of contamination on the site, a number of in-filled ponds were identified within 250m of the site.
The qualitative risk assessment demonstrated that the in-filled land would not affect the site as there were no credible pathways, and as a conceptual model could not be constructed, no further works were proposed.
The desk study report was formally submitted in December 2010 (the desk study report can be accessed from the ‘Documents’ tab on 10/01077/DIS )
