BEACH EROSION AND
REHABILITATION PROJECT: ST
FRANCIS BAY
Introduction
This report has the
objective of informing
Council of the progress with
regard to the beach erosion
in St Francis Bay. Emanating
from the research a way
forward is proposed and
certain decisions are
required from Council in
order to support and resolve
the beach erosion challenge.
This report which may be
seen as an executive
summary, is supported by the
Final Report by ASR Ltd
(Marine Consultants and
Research) dated June 2006
and which will be available
in the main Library (not
attached due to the length
of the report). In addition
during the meeting at which
this report is tabled a
presentation will be made by
the St Francis Bay Beach
Trust to Council.
1.
Background
Development to the west of
St Francis has stabilized
the dunes and thus the
natural ability of the coast
to replenish the beach
within the bay has been
lost.
The Final Report states the
following:
|
“This erosion
has forced
beachfront home
owners to
install rock
revetments “in a
last ditch
effort” to save
their properties
from the sea.
The state of the
beach is now so
severely
degraded that
the high tide
laps up against
the rock
revetments
leaving little
or no beach for
recreational
use. Large
easterly swells
are responsible
for the most
damage with the
most recent
event during
November 2005
causing such
severe erosion
that public
toilets
collapsed onto
the beach.” |
The Final Report emphasizes
the downstream effects of
the erosion on the economy,
in particular the negative
effects on tourism and
longer term job creation.
After years of ineffective
lobbying for a solution to
the erosion problem at St.
Francis Bay residents
combined to form the St.
Francis Bay Beach Trust (SFBBT
– a copy of the Trust Deed
is attached to this report)
and contracted ASR Marine
Consulting and Research
Limited in New Zealand. ASR
are world leaders in the
field of coastal processes,
have developed cutting edge
numerical modelling and
completed the seminal work
in the design and
construction of
multi-purpose reefs.
2. Results of research
Past studies and the ASR
Report have all to a greater
or lesser degree considered
the following options:
The Final Report explains
that due to either cost,
economic losses, unsuitable
environmental conditions in
the Bay area, the
possibility of encouraging
further erosion or a
combination of the
aforementioned reasons the
first five options are
deemed unsuitable. The cost
effective results obtained
from the artificial reefs is
recommended as the most
suitable solution for St
Francis Bay.
The project therefore
envisages:
-
Restore the beach and
therefore the
sustainable supply of an
ecosystem Service.
-
Enhance tourism and
therefore create and
sustain job
opportunities in this
important core industry.
-
Use local services and
suppliers during
implementation, wherever
possible, to support
local industry and
provide employment
opportunities to the
local community,
including initiation and
support of BEE
initiatives.
-
Source funding from the
private sector as much
as possible. The
intention is to raise
the estimated R 20
million required for
implementation and repay
this through a beach
levy paid by property
owners in St. Francis
Bay. (The investigatory
phase including
feasibility study and
detailed modelling and
design phase totalling
some R 1 million has
been entirely funded by
donations from the
residents/private
sector).”
The reference to restoring
the beach involves
acquisition and placement of
the envisaged artificial
reefs and the transfer of
sand from the estuary to the
beach on an ongoing basis.
“The project
offers an opportunity to
provide technology transfer,
through the collaboration of
international and national
experts, to sustain
ecosystem services and its
associated benefits and to
enhance job creation by
promoting St. Francis Bay as
a prime tourism destination
and jump-off point for
nature tourism as indicated
in the report.”
The following extract from
the report summarises the
previous experience and
extent of involvement in the
concept of artificial reefs:
“The first
reef designed by ASR Ltd at
Narrowneck on the Gold Coast
in Queensland, Australia,
won the State Environmental
Award. This project has
demonstrated the
effectiveness of
multi-purpose reef
technology, with significant
widening of the beach
without down stream impacts
(the Narrowneck area of the
Gold Coast has a net
northerly sediment transport
of ~500,000 m3/yr), enhanced
marine life and quality
surfing waves. Similar
multi-purpose reef projects
undertaken by ASR world-wide
are at various stages,
projects that are primarily
for either coastal
protection (erosion control,
submerged port walls), the
creation of surfing breaks
or ecological enhancement,
in New Zealand (8),
Australia (5), the USA (3)
India (2), Bahrain (1), Fiji
(1), Costa Rica (1), Spain
(1) and the UK (4), with
construction of two of these
reefs currently underway and
several others scheduled to
proceed in the next 12
months.
The majority of these reef
projects are in locations
where the existing coastline
is already developed, and
where much of their income
is derived from the tourism
industry – these projects
are 5 often driven by the
socio-economic benefits that
multi-purpose reefs provide.
Indeed, the public’s demand
for beaches for recreation,
combined with the increasing
value society places on the
natural environment, has led
to a dramatic increase in
the development of submerged
reef projects world-wide
(e.g. Ahren and Cox, 1990;
Hsu and Silvester, 1990;
Pilarczyk and Zeidler, 1996;
Hall and Seabrook, 1998;
Black et al., 1998; Harris,
2001; Mead et al., 2003;
Babtie, 2003), and more
recently independent
research is strongly
supporting the findings of
the initial ARP (e.g.
Nielsen, 2001; Houston,
2002; Pilarzyck, 2003;
Ranashinge and Turner, 2005;
Jackson et al., 2005).”
3. Costs and Implications
for the Community within the
Bay Area
Using the ASR Feasibility
Study as a starting point as
well as including other
information available to the
SFB Beach Trust a broad
estimate of costs and timing
(cost as at July 2006) is as
follows:
|
Construction
Phase 1: Year
2007/8 |
|
|
1 x Submerged
Reefs |
R 4 500 000
|
|
Dredger – IMS
Model 5012 |
R 2 800 000 |
|
Sand Pumping &
Renourishment |
R 3 000 000 |
|
Professional
Fees |
R 500 000 |
|
Contingencies |
R 1 000 000 |
|
Total Phase 1 |
R 11 800 000 |
| |
|
|
Construction
Phase 2: Year
2008/9 |
|
|
2 x Submerged
Reefs @ R 4.5 m
ea |
R 9 000 000 |
|
Dune Sculpting
and Replanting |
R 700 000 |
|
Professional
Fees |
R 250 000 |
|
Contingencies |
R 750 000 |
|
Total Phase 2 |
R 10 700 000 |
| |
|
|
Grand Total |
R 22 500 000 |
There is a possibility that
one additional reef may be
required. To be confirmed
following completion of
design phase.
The operational costs would
include:
-
Servicing external
finance and depreciation
-
Dredging costs
(including the fuel,
insurance, labour and
maintenance)
-
Some cost to monitor the
artificial reef
The estimated operational
cost would be in the order
of R 3.5 million per annum.
In order to finance the
operational cost an
estimated special levy (a
beach levy) based on
property valuations for the
properties deemed to be
within the Bay area is
calculated to be in around
R150 per month for each
property owner. This figure
will be further refined in
the months leading to the
budget cycle for 2007/8.
4. Requirements for the
Project
The primary role-players for
this project would include:
-
The National Department
of Environmental Affairs
which has been consulted
and the Minister has
been appraised of the
circumstances and
intentions of the
project. There is
general support for the
initiative from his
Department.
-
The St Francis Bay Beach
Trust which represents
the affected Community
-
Kouga Municipality. This
report formalises the
discussions and contact
with the Municipality
that has taken place via
the Office of the Mayor
to date.
It is not clear whether or
to what extent the spheres
of government will
contribute financially and
hence all costing and
implications in this report
are stated so as to reflect
the maximum burden on the
community. There is an
argument to be made that the
impact of further beach
erosion affects the entire
Municipal area of Kouga.
Nevertheless, the Beach
Trust is proceeding on the
basis that there will be no
contribution in view of the
other priorities facing all
spheres of Government.
The Beach Trust is expecting
to source external finance
and maintain the project
after installation. The
primary aim of this report
is therefore to seek the
support and assistance from
the Kouga Municipality
through the ability of the
Municipality to support the
project via the following
means
-
The external finance (at
this stage an approach
has been made to the
Development Bank of
Southern Africa) will no
doubt require some
security from the
Municipality and in
particular some
assurance of the
appropriate revenue
stream to repay the
loan.
-
To assist the Beach
Trust in accessing the
envisaged revenue stream
through a special levy
to be administered via
the Municipal revenue
systems.
Other than the above support
no other financial
commitment is envisaged at
this stage nor is the
Municipality to accept any
other risks for the venture
such as risks associated
with ownership. With regard
to collection of the special
levy the Beach Trust
envisages doing the
collection of any unpaid
levies and thus there should
be little impact on the
existing administrative
capacity.
The above arrangement would
require a legal agreement in
addition to the external
finance agreement with the
eventual bank. This project
has already had extensive
public participation and
will receive further public
consultation in the coming
months as more specifically
indicated below.
5. Way Forward
In order for the Beach Trust
to proceed there is a need
for the in principle support
from the Kouga Municipality
to assist with raising the
external finance as
mentioned in the report and
to administer and approve
the special beach levy for
the 2007/8 financial year.

7.2 Subject to
recommendation 7.1 Council
supports the initiative and
in principle will support
the St Francis Bay Beach
Trust to acquire external
finance by providing
reasonable security (in the
form of a dedicated revenue
stream),
7.3 Subject to
recommendation 7.1 Council
supports in principle a
beach levy to be determined
in terms of Section 22 of
the Rating of Property Act,
to be applied and recovered
for an area to be designated
in due course, accrue such
levy via the revenue systems
of the municipality provided
that the St Francis Bay
Trust shall accept
responsibility for the debt
collection process for any
unpaid levies and subject to
the SFBBT assisting the
Municipality to obtain the
consent of the majority of
the community affected by
the levy.
7.4 For the purposes of this
project the required consent
of the community be obtained
by recording community
members not in favour of a
beach levy, expressed either
in writing or by signing a
register at any public
meetings for this purpose to
record members of the
community not in favour of
the special beach levy.
