Initially material may look darker than the beach at present and some “cliffing” of the newly deposited material is anticipated as the material sorts itself through natural processes. However the beach will return to its natural profile in time.

Beach Nourishment is the placing of material from offshore onto the beach, in order to raise the Standard of Protection along the frontage for the residents of Eastoke, Hayling Island.

After securing funding from the Environment Agency, Havant Borough Council intends to carry out nourishment to the Eastoke frontage . We are proposing to place 10,000m of material on the front-age to raise the beach to recommended 1 in 200 year Standard of Protection.

The works will involve the following activities:I. Dredging shingle for nourishment from the Chichester Harbour Approach channel;II. Temporary closure of small areas of Eastoke Beach to receive nourishment material;III. Pumping ashore of the shingle from the dredger;

Once the nourishment material has been dredged the shingle will be pumped onto the beach from the dredger by ‘Rainbowing’ previous operations (as shown in photographs). The dredger has a very shallow draft allowing the vessel to come very close in shore and a jet pump was used to put material onto the shore.This will be a 24 hour operation due to the tidal nature of the works. The project may cause some noise disturbance, however we will endeavour to keep the level of inconvenience to a minimum. We request your co-operation for the duration of the works as the project aims to reduce the risk of continuing erosion of the coastline and serious flooding of the Eastoke area.

‘A spectacular sight’

Material for this operation will be dredged from the approach channel to Chichester Harbour.

Shingle material has recently accreted in this area causing a navigational hazard to local mariners. Dredging this approach channel maintains the safe navigation whilst provid-ing flood and erosion risk management to the properties of Eastoke.

Approx. location of dredge

The site for the nourishment is the southern Eastoke frontage at Hayling Island. This area of ongoing erosion requires periodic maintenance. The nourishment operations to help restore beach levels long the front, in order to provide protection to the residents of Eastoke;

In order of preference, the discharge will take place in in front of the Creek Road Car Park (preferred discharge area), with secondary areas further West along the beach are between Groynes 22 - 25.In 1992 a Beach Management Plan was introduced, enabling the sustainable management of the Eastoke frontage. Further developments led to the Eastoke Sectoral Strategy Study, which sets out the Beach Management plan in detail for defending the Eastoke Peninsula.
