Erection of a Replacement 5 Bedroom Dwelling in Steep, Petersfield
Case Study Reference: 09-04-01
Planning Authority: East Hampshire District Council
A desk study was required as a contaminated land planning condition was attached to the decision notice (condition 6a – the decision notice can be accessed here). The condition was attached as historical maps held by Environmental Services show disturbed ground/potentially unknown in-filled ground within 50m of the site boundary.
The site comprised of a dwelling and associated gardens, and whilst the environmental data procured as part of the desk study identified a number of areas of in-filled land, they could not be located on the historical O.S. maps.
Hand held pits were excavated as part of the walkover survey which identified a thin layer of drift deposits over the chalk bedrock, based on the site observations the qualitative risk assessment in the report determined the risk from the potential in-filled land as sufficiently low not to warrant any further works/investigation.
The initial desk study report discounted the in-filled land identified, a revised desk study report was produced which assessed the risk from the in-filled land as very low, which did not require any further assessment / investigation.
The report was accepted by the local authority and the condition was discharged.
