Flood Risk Assessment
EMBM undertakes all aspects of flood risk assessment, drainage design and SuDs assessment in line with the requirements of the national Planning Policy Framework
Flood risk assessments are required for any development in areas of high flood risk, and for all major developments.
Drainage Strategy Reports
Drainage strategy reports have also become a common requirement, and where an increase in runoff results from the development, a sustainable drainage system (SuDS) assessment and design may further be required.
Many business and industrial processes also require flood risk assessments to prevent flood damage and disruption and to comply with the requirements of their environmental permits.
