Flood Risk Management

Management of flood risk and erosion is carried out at a range of scales. At the broadest level, Shoreline Management Plans (SMPs) set the policy context for flood risk and erosion planning over large areas. The next tier of planning is the Flood and Coastal Erosion Risk Management Strategy (FCERMS). This identifies and assesses measures for the eventual implementation of the policies identified within the SMP.

The North Solent Shoreline Management Plan

The Shoreline Management Plan (SMP) is a non-statutory document that provides a broad assessment of the long-term risks associated with coastal processes. The North Solent SMP is the first revision to the Western Solent and Southampton Water SMP and the East Solent and Harbours SMP. The stretch of coastline covered by the plan extends between Selsey Bill in the east, to Hurst Spit, in the west, including the Southampton frontage. Southampton City Council contributed to the development of this plan, which was led by New Forest District Council.

The North Solent SMP was adopted by Southampton City Council on 25th October 2010. Following adoption of the plan by each of the contributing local authorities, the SMP was submitted to the Environment Agency and received formal sign off in December 2010. To view the final SMP documents, follow the link to the North Solent SMP website in the related links section of this page.

River Itchen, Western Shore, Netley and Hamble Coastal Technical Study

The Coastal Technical Study was originally being developed as a Coastal Defence Strategy, which begun in 2005. Development of the project was delayed due to the introduction of new legislation leading to a significant delay in the schedule. Due to the development of the project spanning several iterations of guidance updates and the minimal need for schemes for either coastal erosion or flood defence in the study area, it has not been considered appropriate to take this study forward to a formal Coastal Defence or Coastal Flood and Erosion Risk Management Strategy. Not withstanding this, the study has provided technical input to the finalised North Solent SMP (2010) and will provide technical support for any future coastal projects and schemes. To download the final study reports, see the downloadable documents section. The appendices are available on request using the contact details below.

Southampton Surface Water Management Plan (SWMP)

The Surface Water Management Plan maps the areas within Southampton where risk of surface water flooding exists, determining the potential extent and consequences in order to establish priority areas. Following a high level appraisal of the options, the SWMP outlines a number of recommendations which detail the preferred option to manage the risk for each of the high risk hot-spot areas. A total of eight hot-spot areas have been identified. They are

• Merging point of Tanners Brook and Holly Brook
• A33 Millbrook Road West
• Southampton Central Station
• City Centre (St Andrews)
• City Centre (Queens Park)
• West Quay retail area (Western Esplanade/Harbour Parade)
• Stoneham Way (Junction with Wide Lane)
• Shoreburs Greenway (Millers Pond)

The recommendations for managing surface water at these locations are outlined in the SWMP Volume 1 report, which is available to download below. Implementation of the SWMP will begin early in 2012, taken forward in partnership with the organisations that were involved during the development of the SWMP. These include the Environment Agency, Southern Water, Associated British Ports and Network Rail.
