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 masonary sea walls.
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 now intends to carry out the second phase of the operation
this summer. This involves 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 will take
approximately 2 months to complete, dependant on weather and the
dredger commitments.
The estimated arrival date of the Dredger is
between 10th June - 17th June 2009. This start date is
subject to change dependant on weather and the dredger
commitments.

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
infront of the now redundant sea wall. Coastal processes are
constantly eroding this frontage and without intervention the
redundant se 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.

Protection to Broadmarsh and
Southmoor
Coastal defences at Broadmarsh were renewed by the
Council in the early ninties and Southmoor in the late ninties.
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 are due to be carried out in 2008.
