Basement impact assessment

Due to the significant increase in basement redevelopment and extension in the London area over the past 10 years or so, several London borough councils, including the London Borough of Camden, Royal Kensington and Chelsea and Richmond upon Thames, have published planning guidance documents relating to basement development.

The guidance documents commonly require an assessment to be undertaken at the planning stage, as part of a Basement Impact Assessment, which includes an assessment of risks posed by groundwater and flood risk from surface water and sewers.

Contact Groundwater Solutions to discuss your requirements for a Basement Impact Assessment.
