There has been a strong desire amongst Solent Forum members to find solutions to the many barriers which are preventing the effective use of dredged material to augment Solent intertidal sites and, hence, to provide other benefits associated with such restoration work (especially enhanced coastal protection). The Forum’s role will be to manage the project and facilitate future communications. For more detailed information please download the BUDS Terms of Reference.
The Solent Forum now seeks to build on past work and lead on the development of a proposal that will:
More specifically the project will aim to:
This work should build on a wealth of information much of which relates to the Solent including amongst others work from the River Hamble Harbour Authority, the University of Southampton and Lymington Harbour. It is important that the work does not replicate previous work and that the budget is used to further the delivery of beneficial use projects.
It will only be possible to make real advances in the Solent if the benefits of the re-use of dredging material is really understood and costed, and these benefits are aligned to objectives of regulatory bodies and coastal managers.
The project comprises three phases. Download the project brief.
Phase 1 of the project was conducted by ABPmer. This phase included a Stakeholder Workshop. The main areas of work included:
Feasibility Study and Detailed Cost Benefit
Develop options for the Solent for a project(s) for beneficial use within a set time period and for preferred options to develop full feasibility plans for actual use of dredging at some key sites. Key site selected: Western Solent and Lymington Marshes. To consider whether a scheme may be a one off or one that can be repeated. This study would detail exact timings and costs of sources of sediment to match with receiver site needs. It would identify funding sources for complete projects. The beneficial costs will be firmed up so as to fully calculate cost benefit. Licences and permissions to be fully scoped ready to obtain. EIAs conducted.
ABPmer were contracted for this work.
The Phase 2 report was published in February 2020.
Key stakeholders helped develop strategic guidance and a protocol. Led by the Solent Forum it built on from Phase 1 work, using workshops and stakeholder meetings. Specifically it:
The aim of this phase is to secure a Marine Licence (and any other necessary consents) that will enable the bottom placement of sediment in a number of locations in the Western Solent (west of Lymington), by third parties operating under their own dredge disposal licence. This phase will include all consents and permissions to place dredging’s. This phase will include the identification of a methodology/system that will enable third parties to have a viable alternative to their current practices of disposal providing that the dredge material to be disposed of is of suitable sediment type and has passed Cefas contaminants analysis. This will thereby ensure that there is an opportunity to facilitate change. The success of this phase will mark an important success for BUDS and the overall objective of the project, to offer third parties a beneficial alternative to the current practise of disposal at licensed offshore deposit ground. Once the grounds become used, income can be derived to ensure that on-going project costs are met including any monitoring costs. This phase includes setting up this system. Phase 4 is more ambitious and involve higher costs as would involve placement of sediment on the marshes at Lymington. Funds for this phase have not yet been raised. Phase 3 does however include some Phase 4 elements including: full costings and cope for phase 4 and consents for phase 4 where possible.
Please see the project brief for more information. The project started in April 2021 and will conclude in March 2023.
Phase 4 will be progressed once Phase 3 is complete and funding has been secured.
This report reviews the status of Wightlink Ltd.’s saltmarsh enhancement and mitigation project at Lymington. This enhancement project was completed nearly eight years ago. It involved the use of maintenance dredge sediment from the Lymington marinas and harbour approaches to ‘recharge’ an eroding area of saltmarsh (Boiler Marsh) to the east of the Lymington River entrance.
