The brief
We were commissioned by a primary school in the London Borough of Hillingdon, following accusations of the school drainage systems leading to neighbouring residential surface water flooding.
What we did
Our freshwater ecology team, alongside our GIS specialists, undertook digital mapping and a desk study of the following:
- site drainage and asset location,
- topography,
- geology,
- soil permeability,
- groundwater, and
- Environment Agency flood mapping.
We also conducted site visits to establish the site configuration and constraints. This included meeting with the complainants and school representatives to establish current understanding of the issues.
The outcome
We were able to summarise the functioning of the site, alleviate the concerns of the residents as to the school’s contribution to the flooding and make recommendations for the residents to improve the situation.
