Two parcels of land either side of a railway had been purchased for residential redevelopment. The Northern area of land had been previously used for the storage of coal and fuel products. The Southern site had similar uses, plus a former (in filled) reservoir that dated back to the use of steam trains. Part of the Southern site operated as a garage with several out buildings (Sandbrook Gorge).
A Phase I desk study was completed to assess the general environmental liability associated with the sites. Following this, Phase II and III intrusive Site Investigations were undertaken to establish geotechnical design parameters for highway, drainage and foundations design. In addition, the type degree and extent of residual chemical contamination was established at the sites. Elevated organic chemicals were found within the infill material of the reservoir, which was suitably remediated prior to redevelopment.
