INTRODUCTION
Adverse weather systems can produce storms that generate strong winds, large waves and elevated
ocean water levels along the NSW coastline. These conditions are generally short lived but can result
in extensive erosion along sandy beaches, and seawater inundation where waves can overtop
coastal dunes or sea defence barriers.
Extreme beach erosion can directly threaten assets and infrastructure on an active beach.
Erosion can occur either through erosion of the dunal system as a result of undermining, or indirectly
because the foundation of the remaining dune adjacent to the eroded area has been reduced.
Erosion can also lower the beach berm (a nearly horizontal plateau on the beach face or backshore,
formed by the deposition of beach material by wave action, or by means of a mechanical plant as part
of a beach recharge scheme), often resulting in a tall, unstable, near-vertical back-beach erosion
escarpment. Damaged berms can also present hazards for beach users.
Even without severe coastal storms, an erosion escarpment can erode and migrate landward.
Relatively minor wave action coinciding with high spring tides can induce erosion and undercut an
erosion escarpment.
A council’s long-term strategy for managing these threatening processes should be documented in a
coastal zone management plan (CZMP). An emergency action subplan (EASP) forms an integral
component of a CZMP. It outlines a council’s intended response to a coastal erosion emergency and
explains ways in which and where beachfront property owners can place emergency coastal
protection works according to the Coastal Protection Act 1979 (CPA). (OEH, July 2011)
1.1
Context and a ssociated Plans and Guidelines
This Emergency Action Sub Plan (EASP) has been prepared in accordance with provisions of the
Coastal Protection Act 1979 and is intended as an interim measure, prior to the implementation of
the Wooli Village Coastal Zone Management Plan. This Emergency Action Subplan for Wooli
Beach should be read in conjunction with the following associated plans and guidelines:

NSW State Storm Plan (SES 2007) – prepared under the State Emergency and Rescue
Management Act 1989 and State Emergency Service Act 1989.

Clarence Valley Local Flood Plan (interim) – A Sub-Plan of the Clarence Valley Local Disaster
Plan (DISPLAN) (CVC, November 2007)

Coastal zone management guide note – Emergency action subplans (OEH, July 2011)

Guide to the Statutory Requirements for Emergency Coastal Protection Works (DECCW
2011a)

Code of Practice under the Coastal Protection Act 1979 (DECCW 2011b).
Page 2
Exhibtion Draft – October 2011
ITEM 12.201/11 - 5
This EASP should be reviewed periodically in conjunction with the review of Council’s DISPLAN,
Flood Plan and following a coastal erosion emergency event as defined in Section 1.2.
1.2
P u r p o s e o f E m e r g e n c y Ac t i o n P l a n
The objective of the Emergency Action Plan is to document the actions that Clarence Valley Council
and/or landowners will or can undertake in response to a coastal erosion emergency situation at
Wooli Beach. This includes actions performed by Council/landowners whether associated with action
under any plan made under the State Emergency and Rescue Management Act 1989 (SERMA) or
not. However, in accordance with section 55C(2)(a) this Plan will not include matters dealt with in any
plan made under the SERMA in relation to emergency responses by Council/landowners.
To achieve this objective action is required in emergency planning/preparedness, response and
recovery phases of an emergency. The primary focus of Council will be to prevent harm to, or loss of
human life. Secondly, Council will seek to ensure public assets, such as formal beach access and/or
infrastructure are managed in a safe manner. Private property management has a lesser priority and
in this regard Council will facilitate authorised and lawful actions by landowners once Council’s priority
obligations are fulfilled. This is consistent with standard emergency management procedure.
The NSW Government has issued a direction to CVC to prepare a draft emergency action plan for the
costal erosion hot spot at Wooli Beach, being the beach opposite the Main Street & Riverside Drive
intersection south to the Wooli Wooli River. This draft Subplan will cover that area plus the length of
Beach to the northern side of the new residential area, in the vicinity of the beach access known
locally as ‘One Tree’.
A “coastal erosion emergency” is classified (for the purposes of this plan) as an oceanic event that
could result in lowering of beaches, high unstable erosion escarpments and/ or direct threats to
public and private assets from undermining or wave action. A coastal erosion emergency could
occur due to a combination of elevated ocean water levels and waves that are not generated by a
severe weather event that would otherwise trigger actions under the State Storm Plan, Local Flood
Plan or DISPLAN.
1.3
As s e t s p o t e n t i a l l y a f f e c t e d b y B e a c h E r o s i o n
Wooli Beach suffered severe storm damage in 1954, 1974, 1996 and 2009. More recent erosion
events have eroded the frontal dune leaving a high, steep escarpment along much of the beachfront.
The steep escarpment remains unstable and has continued to recede due to slumping.
Page 3
Exhibtion Draft – October 2011
ITEM 12.201/11 - 6
A review of coastline hazard lines for Wooli (WorleyParsons, 2010a) has identified that 44 lots are
located in the zone of wave impact for a severe storm (although a few dwellings on these lots are
located landward of the immediate impact line). These beachfront properties are all located south of
the bowling club. In addition, monitoring by Council in 2007 identified approximately 20 beachfront
dwellings located within the ‘zone of reduced foundation capacity’ (less than 18m from the dune crest)
which are susceptible to structural damage due to the reduced bearing capacity of sand in this zone.
Of the 20 properties, the nine most at risk were located around 13 to 14m from the dune crest.
Management of the impacts of coastal erosion at Wooli is further complicated as the village is not
serviced by reticulated sewerage. On-site effluent management systems are located on each
property containing development. Most of these systems and associated disposal areas (as
applicable) are located on the seaward side of beachfront dwellings along the frontal dune. Erosion
that enters private lands or other lands containing effluent systems is likely to adversely impact such
systems with implications for occupants as well as public and environmental health.
In addition to wave impacts from coastal storms, Wooli is subject to flooding from the Wooli Wooli
River. During a 1% or 2% Annual Exceedance Probability (AEP) flood event, inundation of Wooli
Road (in the vicinity of the Wooli Sportsground) is estimated to be 0.35m. In a more severe event,
the road would be cut between the northern portion of Wooli and the original village .
In addition, flooding in the adjacent catchment, which typically occurs a day or more after a major
coastal storm event, can cut road access at Sandy Crossing and Whites Bridge, isolating Wooli from
between a few hours to a few days. This occurred following the storm in late May 2009.
The latest review of coastal hazards at Wooli Beach (WorleyParsons, 2010a) as well as the Wooli
Beach Coastline Study (1997) endorsed the finding of an earlier Public Works (1989) report, Wooli
Coastal Process Investigation, that if the frontal dune were ultimately to disappear there is potential
that the ocean could breakthrough to the River during times of high seas and river flooding in the
future. See Appendix 1 for a map showing the potential break through location.
Council infrastructure may also be at risk in some locations. In the short term this is
expected to be confined to pedestrian and 4WD beach accessways. Continued landward
recession of the dune escarpment would affect road assets, public infrastructure and
services, in the longer term.
1.4
Clarence Valley Local Flood Plan
The 2007 Clarence Valley Local Flood Plan (sub-plan of the Clarence Valley Local Disaster Plan
(DISPLAN)), being a Plan prepared under the SERMA, guides emergency activities in the event of
flood and/ or coastal erosion. This Plan is currently an interim document and is being revised by SES
personnel. General evacuation triggers in the Local Flood Plan are:

failure of essential services;
Page 4
Exhibtion Draft – October 2011
ITEM 12.201/11 - 7

flooding affecting properties; and

isolation of properties (particularly where residents require access to medical help).
The Local Flood Plan also covers resupply of settlements which become isolated. All of Wooli is
affected by the Probable Maximum Flood (apart from the foredune). In a 1% AEP flood event, Wooli
Road, some properties to the east of Wooli Road and some properties to the west of Main Street (at
the northern end of the original Wooli Village) are affected.
Flood evacuation triggers (i.e. flood heights) are still to be determined for Wooli. However, the
northern and southern portions of Wooli can be cut off from each other before over-floor flooding of
dwellings occurs.
Information on major flooding and storm events is available to residents by phoning the State
Emergency Service (SES) 132 500 number (the SES advises on local road flooding). In the event
that power and phones are out, the Wooli Post Office is the point of contact for residents. The SES
has access to a boat which can be used to ferry people out and bring supplies in when the road at
Sandy Crossing floods. In the event of a medical or other emergency the Wooli Sportsground oval
would be used as a helicopter landing pad. Signs are also installed to warn that roads are
impassable (pers. comm. Ann Mara, local SES Coordinator).
Annex Z of the Local Flood Plan addresses the management of coastal erosion. When the
Bureau of Meteorology (BoM) issues a Severe Weather Warning for dangerous waves or storm surge
(a forecast for onshore waves of 5m or more, or storm surge of 0.5m or more for the NSW North
Coast) the role of the SES is to advise the community of the storm; protect life through warning and
evacuation; and coordinate lifting/ relocation of readily moveable household items and commercial
stock and equipment. It is also noted in Annex Z that the SES may initiate response operations when
large storm induced waves are observed locally and no BoM warning has been issued.
When a BoM warning has not been issued, and the SES has not mobilised in response to an
imminent storm, Council’s role is essentially the same as the SES’s role because the adopted
Coastline Management Plan (1997) nor the Draft Wooli Village Coastline Management Plan
(WorleyParsons, 2010) proposes property protection works. See also Sections 1.3 and 1.4 of this
Subplan. An event that prompts an SES response under the Local Flood Plan may still require
certain actions to be undertaken by Council. This Subplan documents all actions to be taken by
Council associated with a coastal erosion emergency, whether the event is administered under the
Local Flood Plan or not.
1.5
Code of Practice for Emergency Coastal Protection Works
A Code of Practice (DECCW, March 2011), under the CPA 1979, and a Guide to Statutory
Requirements for ECPW (DECCW, 2011) details the requirements for ‘emergency coastal protection
works’ undertaken by landowners where certain physical and weather conditions exist. This includes
the ability to install such works where the most landward part of the erosion escarpment is within 20
metres of the most seaward wall of a building lawfully used for residential, commercial or community
Page 5
Exhibtion Draft – October 2011
ITEM 12.201/11 - 8
purposes. Monitoring (as at 2009) by CVC estimates that 35 dwellings are 20 metres or less from the
erosion escarpment. These properties are shown in Schedule 1.
Under the Code works can be comprised of either placement and maintenance of sandbags up to 1.5
metres in height or the placement of sand against the seaward side of the erosion escarpment.
Any works performed by landowners must be in accordance with a permit issued under Part 4C of the
CPA 1979 and Regulations, the Code of Practice (DECCW, 2011) and the Guide to Statutory
Requirements (DECCW, 2011). Sand bags used for ECPW can only be made of geotextile or woven
polypropylene fabric (not hessian) up to a capacity of 0.75m3. It needs to be recognised that
compliance with the Code will not guarantee protection of property from the impacts of an erosion
event.
Access to the Beach to undertake ECPW must be via the 4WD beach access off South Terrace (see
Figure 1) as the ‘authorised beach access’ specified in the Code of Practice and Guide to Statutory
Requirements.
Landowners of beachfront properties with residential, commercial or community buildings need to be
made aware of the potential to undertake ECPW and requirements for such actions in the
planning/pre-storm phase.

EMERGENCY ACTION SUBPLAN
Under each phase in emergency management the triggers for response and emergency actions are
outlined. Table 2.1 lists actions to be taken by Council prior to, and if the triggers are met. It is
envisaged that the SES would be involved if a significant number of dwellings at Wooli were
threatened and/ or a coastal erosion event coincided with a major flood event, requiring whole scale
evacuation from the original Wooli Village. Accordingly, only arrangements for evacuation within
Wooli are included in Table 2.1. A diagrammatic representation of the actions in Table 2.1 is shown
in Appendix 2.
