OPW22-0251 - DA Form1 & 2 & owners consent

It appears that operational works for the proposed revetment wall and bank stabilisation may
impact on marine plants. Under the Planning Regulation 2017, works involving the removal,
destruction or damage of marine plants must be undertaken in accordance with the relevant
accepted development requirements (ADR) or under a development approval (assessable
development). The proposed works may comply with the ADR if the impact to marine plants can
meet a prescribed work type. If the works cannot meet a prescribed work type, then a
development approval will be required for assessable development that is the removal,
destruction or damage of marine plant. Please refer the applicant to DAFs webpage, protection

and management of marine plants for more information.

Department of Environment and Science (DES)
Department of Environment and Science advised that they have no objections to the issue of
owners consent.
The following additional advice is recommended to be submitted to the proponent for any
subsequent development application:
e Revetment walls are defined as an erosion control structure and considered as coastal
protection works.
e Submission of adequate documentation and compliance with the SDAP State code 8 will
be a requirement for assessable development under the Planning Act 2016.

Please refer to the Guideline: State Development Assessment Provisions, State Code 8: Coastal
development and tidal works https://environment.des.qid.gov.au/coastal/development/pdf/state-
code8-coastal-development-tidal-works.pdf in responding to State Code 8. The guideline
provides background information and key concepts relevant for coastal processes and resources
and coastal protection and management applicable to complying with the code. The guideline
also contains information on how to respond to particular performance outcomes (PO) and
specific information requirements.

Revetment walls are generally only supported by the State under Performance Outcome PO11 &
PO12 of the State code 8 when there is an imminent threat to significant buildings or
infrastructure, and there is no feasible option for either:

a. beach nourishment; or

b. relocation or abandonment of structures;

Revetments differ to other erosion control structures in that they are designed to protect a
specific part of land, often defined by lot boundaries and provide a very high certainty of
protection. A smooth alignment of revetments along a coastline and riverine system is important
to ensure the impact on coastal processes is minimised. The preferred hierarchy of responses to
erosion risk applies to revetments just as it does for other erosion control structures. Noosa Shire
Council has endorsed a Shoreline Erosion Management Plan (SEMP) that has been supported
by DES, the recommendations of that plan are the preferred approach for deciding the location
and design of coastal protection works. Please check with Council’s SEMP regarding preferred
methodology for erosion control structures along the Noosa River.

Although owner's consent for the development or change application has been provided, your
client is always required to comply with the purpose, terms and conditions of Term Lease
0/238031 — Lot 164 on CP907410 and undertake works only if and when the development has
been approved by the assessment manager or responsible entity, and in accordance with the
conditions of that approval.
