There are three 'statutory reservoirs' on Hampstead Heath but two chains of more than 12 reservoirs.
The presentation will describe the process followed, which identified a significant deficiency in spillway capacity down the two chains, the way in which the flood study calculations were carried out, the risk assessments made, and the design decisions made.
The works include a new embankment and a raised dam to provide additional flood storage capacity.
The presentation will describe the significant amount of consultation undertaken and the concerns voiced by the stakeholders.
This event is being broadcast online. Please join the lecture 10 minutes before the start time of 6pm.
