In June 2018 we started work on a Shoreline Management Plan for Jersey. This plan aims to ensure that our coastal defences continue to protect the island over the next 100 years.
draft Shoreline Management Plan is available for you to read.
Our existing sea defences and drains protect us from flooding during storms, high tides and heavy rainfall. However, rising sea levels and more rainfall will increase the risk of flooding in some areas of Jersey.
The following work has already been done in order to create the plan:
- analysis of coastal processes, existing coastal defences and future coastal change
- development of policies which consider different approaches to shoreline management
- Jersey’s shoreline split into coastal management areas and sub-units for separate consideration
- economic assessment of each policy option and understanding the implications for the community, environment and economy
- consultation on the draft Shoreline Management Plan (July to September 2019)
The following is still to come in 2019:
- review of consultation responses and finalising the Shoreline Management Plan (October to November 2019)
- create an action plan detailing flood management schemes for specific areas at higher risk of flooding (November to December 2019)
Shoreline Management Plan policy options
Shoreline Management Plan splits the island’s shoreline into units called coastal management units (CMUs). For each CMU the risks associated with coastal flooding have been assessed and a policy option proposed for managing those risks.
The 4 policy options are:
No action intervention
A policy decision to not invest in coastal defences or maintenance work. The shoreline is left to naturally evolve without intervention. This policy will generally be applied to natural areas of the coastline which are currently undefended.
Maintain the defence line
Existing coastal defences are maintained. The level of flood protection may decrease in some locations over time due to climate change. This policy will generally be applied where the existing defences provide a reasonable standard of flood protection or prevent erosion of the shoreline.
A policy to proactively manage and mitigate coastal flood or erosion risk. The policy will be delivered through various management initiatives depending on the level of risk and the circumstances. This could include improving the standard of flood protection for an existing sea defence, constructing new defences, raising awareness of local flood risk or recommending property level flood protection.
Advance the line
New sea defences are built seaward of existing defences. This policy will only be implemented in areas where there is a significant risk of coastal flooding or erosion, or where it will deliver additional benefits for the community, environment and economy, such as creating a new amenity space.
Policy options are proposed for each of the following periods:
- short term (next 20 years)
- medium term (between 20 to 50 years)
- long term (between 50 to 100 years)
Shoreline Management Plan public consultation
The consultation closed on 27 September 2019.
Consultation responses are being reviewed and changes to the draft Shoreline Management Plan considered. A consultation report will be published with the final Shoreline Management Plan by the end of November 2019.
The finalised Shoreline Management Plan will feed into the
Island Plan Review process.
During July 2019 we ran a series of information sessions. You can download the Shoreline Management Plan public consultation presentation.
