Site Appraisal, this is a limited service that PRP can provide to potential developers, the purpose of this service is to advise developers on engineering and environmental hazards present on a site, such hazards may include visible contamination, disposal of surface and foul water and topographical issues. Access to the national geological database will provide useful information which can be useful to determine preliminary guidance on foundation types for all kinds of buildings at a very early stage. 
 
Preparation of full and interpretative reports including GQRA and DQRA risk assessments.

flood risk assessment
flood risk assesment 
 
Flood Risk Assessments (via PPS 25) are a planning requirement on many sites. Factors to be considered vary from site to site but always require appraisal of the site surface, water drainage and the effects of climate change.

Work that might be required on a project might include assessment of flooding effects from the sea, or watercourses such as rivers, streams, and ditches. This would include, when necessary, hydraulic modelling of water courses or breach analysis when flood defences are involved. An outline analysis of the storm water drainage design is a fundamental requirement in most cases. 
 
Our site specific reports cover all relevant issues, including the results of liaison with The Environment Agency. These reports encapsulate the appropriate analysis and assessments and, where necessary, will include specifying design considerations to mitigate flooding effects and the preparation of evacuation plans.
