Management Act 2010 and the identification of Local Authorities within England and Wales as Lead Local Flood Authorities. The role of the LLFA’s was to formalise the flood management and mitigation measures as well as introduce a risk management approach across a number of differing disciplines within Local Authorities including, Development & Planning, Transportation, Response and Resilience. As part of this Flood Management process the introduction of the following elements ensured there was a standardised approach with milestones that could be auditable and managed so aiding the whole concept of Flood Risk Management. The elements included:- a) Flood Risk Strategy; b) Preliminary Flood Risk Assessment; c) Surface Water Management Plan; d) Multi Agency Flood Response Plan. e) Flood Risk regulations (consultation for implementation in Dec 2015) This foreword introduces the strategy of the London Borough of Havering as required by the Flood and Water Management Act 2010 and the liaison that has been carried out as part of the Drain London Project and the Lead Local Flood Authority responsibilities for flood risk management. This page has been left blank intentionally. Introduction The Havering Local Flood Risk Strategy is an important new tool to help understand and manage flood risk within the Borough. It principally looks to tackle ‘local flood risk’, that is to say flooding from surface water, groundwater and ordinary watercourses such as ditches and streams. This type of flooding is responsible for most of the households flooded in England, but until now there has been little to address these forms of risk. The strategy will look to address this gap. However, for those who suffer from flooding, it doesn’t matter what type of flooding it is, so this strategy also provides information
