The Environment Agency and Sedgemoor District Council have met with representatives from a variety of organisations this week to discuss options for a £32 million flood barrier on the River Parrett, one of the actions proposed in the Somerset Flood Action Plan.
The meeting follows earlier discussions in June 2014, when a decision was made to prepare a technical review as part of Somerset's Flood Action Plan. The review drew upon experience from recent flooding as well as a wealth of information gathered over the years by various organisations including the Environment Agency, Sedgemoor District Council and the Internal Drainage Boards. It was published in December 2014.
The review supports previous findings that a tidal surge barrier (one which operates when it is necessary to exclude the highest tides and protect from storms) would provide the best long term flood protection and has the best prospect of being delivered. This is in line with the adopted Local Development Framework for Sedgemoor District Council previously approved by councillors and accepted by the Planning Inspectorate after independent Examination.
A spokesman for Sedgemoor District Council said:
'The technical review provides up to date evidence and analysis of flood risk and infrastructure options. The work funded so far by the Environment Agency and Sedgemoor District Council, is very important. We are working closely with the Environment Agency to accelerate the delivery of a barrier and improve flood protection for local homes and businesses'.
Current timetable for the project is as follows:
- Feasibility & Business case will start July 2015 for completion by July 2017
- Detailed Design & Planning to start August 2017 for completion by December 2019
- Construction to start January 2020 for completion by October 2022
- Ongoing commissioning and operation will commence in November 2022
The current best estimate of the capital cost to build a tidal surge barrier is £32.4 million. This includes work to downstream embankments which will cost approximately that will be required to mitigate for increased downstream water levels.
Assuming funding is available the structure could be built by 2022. Funding from Sedgemoor District Council through the tariff and other flood risk management funding has already been identified which will fund the feasibility and planning stages. The future construction cost will be secured through normal flood management funding routes.
