The Council invests
resources each year into maintaining its existing coastal defence
structures. This extends the life of the assets and ensures the
appropriate level of protection is sustained. Examples of
maintenance works undertaken are:
- Shingle Recycling.
- Beach Nourishment.
- Replacement of timber planking on groynes and revetments.
- Repairs and maintenance of topmarks.
- Concrete repairs to sea walls.
- Basket repairs to gabion sea walls.
- Repointing to masonry sea walls.
Eastoke Point Coastal Defence Works
Following the recommendations of the Eastoke Sectoral Strategy
Study, Havant Borough Council commissioned HR Wallingford to
undertake the 'Eastoke Point Coastal Defence Study'.
The primary objective of the study has been to develop a
sustainable coastal defence scheme for managing coastal erosion and
flooding risks along the Eastoke Point frontage. Situated in
the south eastern corner of Hayling Island, this is a highly
dynamic coastline that is becoming increasingly difficult to manage
and maintain.
The study was completed in 2009 and has identified an outline
scheme to reduce the risk along this frontage.

Nourishment Works September 2009
In September 2008, Havant Borough Council
successfully completed phase one of the Beach Nourishment scheme
placing 25,000m³ of material on the frontage of Eastoke.
After securing funding from the Environment Agency, Havant Borough
Council carried out the second phase of the operation
this summer (2009). This involved placing a further 65,000m³
of material on the frontage to raise the beach to the recommended 1
in 200 year Standard of Protection. The works took
approximately 1.5 months to complete.
Work started on the 19th June 2009 and was
completed on 2nd Aug 2009.

scheme please follow the link below:
Beach Recycling
The Eastoke Peninsula is a densely populated area. the
majority of it is low-lying with a record of serious flood
incidents prior to 1985. Since the 1930s hard defences were
constructed to fix the line of this frontage, but regular
overtopping and flooding was experienced. In 1985 the beach
nourishment scheme was implemented creating a man made beach in
front of the now redundant sea wall. Coastal processes are
constantly eroding this frontage and without intervention the
redundant sea wall would again be exposed. The result would be a
return to serious flooding to Eastoke, through continuing erosion
to the coastline.
The annual operation of moving
shingle, from areas of accretion to the East and West of Eastoke to
depleted areas along the Eastoke coastline, in accordance with the
Beach Management strategy. This is consistent with recommendations
from the East Solent Shoreline Management Plan (ESSMP) which
considers the community, economy and environment.
This year, we undertook our recycling operation
during March. The drawing illustrates the areas where we extracted
and deposited material. Extraction sites included behind
the revetment at Inn on the Beach, the Coastguard station and The
Ness. This is where there is a large amount of material naturally
accreting. This material was then transported back to the
Eastoke frontage to protect depleted areas.

South West Hayling Island Beach
Management Study
The South West Hayling Island Beach
Management Study is being carried out to develop a sustainable
framework for managing coastal risk, predominantly erosion, around
South West Hayling. The study is designed to inform and
enhance the coastal management capabilities of Havant Borough
Council around the Hayling open coast. The key issues to be
considered include co-management of the study area and the Eastoke
frontage, and the management of existing defences in line with the
current shoreline management policy.

Protection to Broadmarsh and
Southmoor
Coastal defences at Broadmarsh were renewed by the
Council in the early nineties and Southmoor in the late nineties.
Failure of these defences would have led to significant damage to
the environment, due to the subsequent erosion potentially causing
the waste materials deposited in these areas to contaminate the
Harbour.
Some repairs to the armor loc and armor flex revetment at
Broadmarsh revetment were carried out in 2008.
