Dear Sir/Madam
Information Request
Planning Act 2016
I refer to your application and advise that Council requires further information to satisfactorily assess the proposal.
application details
Application No.	MCU20/0013
Street Address:	1, 3 and 9 Maple Street COOROY  QLD  4563
Real Property Description:	Lot 1 RP 153299 Lot 2 RP 153299 Lot 3 RP 230055
Planning Scheme:	The Noosa Plan (8 June 2018)
INFORMATION REQUIRED
The information requested is set out below:
FLOODING
Issue:
Additional flood figures are required to properly understand the flood risk at the site.
Information Requested:
Provide flood model results for the 1 in 5 year ARI event in order to determine the extent of compliance with the LGIP desired standards of service for public parks
Provide flood hazard mapping for each AEP for the developed site based on the hazard categories of ARR2019 and include the description of each hazard category on each figure.
Update all flood mapping figures to show the extent of the car parking works on all figures.

Provide a topographic differences plot so the extent of earthworks for the park and the car parking can be clearly understood
Clarify the level of flood immunity achieved for proposed facilities and infrastructure such as toilets, shelters, bbqs
Provide further advice on the consequences of the predicted flood impacts to the Council-owned land at 4-8 Lower Mill Rd. Although owned by Council, this land contains tenants which may be affected by the predicted flood impacts. Either eliminate the flood impacts from this parcel or justify why the consequences of these impacts should be acceptable.  In the response, provide surveyed floor levels for each of the tenancies and specifically comments on the existing flood immunity of the tenancies and whether the development will increase over-floor flooding (either frequency of occurrence or depths).
Demonstrate that the development is resilient to natural hazard events by ensuring siting and design accounts for and minimises potential risks of natural hazards to people and property. In this regard, clearly demonstrate how the proposed design and materials minimise potential risks of natural hazards to people and property.
Issue:
Local overland flowpath flooding
Information Requested:
Provide flood inundation and flood impact mapping for the local flood event associated with the external urban catchment which flows through the site.
Issue:
Toilet Block
The proposed toilet block appears to be well below the applicable Minimum Floor Height in this area. This is very concerning for the potential of causing surcharge in the sewer system.).
Information Required
Provide plans/information to indicate the relevant levels of proposed plumbing works associated with toilet block and clearly specify the measures to prevent any potential of sewer surcharge during major storm events (1% AEP and over).
Update plan where required.
Issue
The location of the carpark requires users of the playground to traverse a bridge, at times likely to be affected by flooding.
Information Required
Demonstrate the suitability of the pedestrian path across the creek to the car park in the event of a flood event.
Demonstrate that the access path over the creek meets the relevant Australian Standards.
Issue:
The proposed park has been shown to be significantly inundated in very frequent flood events.
Information Requested:
Update the park design sections to include design flood levels on each section. Specifically identify the proposed level of flood immunity for facilities and infrastructure such as toilets, shelters, bbqs etc.
Demonstrate how proposed installations and furniture in the park (eg wooden structures, logs, trash/garbage bins) will not be dislodged in a flood event and cause blockage or impede flows through downstream culvert/s and or floodway.

WATER QUALITY
Issue:
It appears that the ‘frog pond’ will be created by impounding runoff from the upstream external urban catchment which flows through the site. This runoff will not be suitable for primary contact recreation and will be subject to persistent water quality issues.
Information Requested:
Revise the design for the management of the external urban catchment which flows through the site so that recreation and access is consistent with the anticipated water quality. It is suggested that a densely vegetated ephemeral swale (which restricts access and is free-draining) is a more appropriate outcome.
TRAFFIC
Issue
The application has not addressed the impact of the development on the traffic conditions in Maple Street, Mary River Road and Cooroy CBD.
Information Required
Provide traffic assessment prepared by suitably qualified RPEQ to address the impact of the development on the traffic in Maple Street, Mary River Road and Cooroy CBD. Update plans where required.

ENVIRONMENTAL
Issue
The playground is located within the Riparian Buffer Area of the Noosa Plan. The Noosa Plan seeks to exclude development from the Riparian Buffer Area.
Information Required
Clearly demonstrate how the proposed playground meets the Biodiversity Overlay Code for the Riparian Buffer Area, in particular Specific Outcome 5.
Demonstrate that there is an overall improvement to the water quality outcomes associated with the site by conserving, managing, enhancing and rehabilitating the ecosystem health and quality of stormwater entering receiving waters. In this regard, it is noted that water quality outcomes for the car parking within the Maple Street road reserve has not been addressed.
Issue
Vegetation in the riparian buffer area is proposed to be removed to facilitate a viewing platform(s) according to Attachment A in the Assessment of Environmental Values – Hinterland Playground, Callaghan and Toth. However the flooding study indicates no viewing platforms are proposed.
Information Required
Clarify if and where viewing platforms are proposed. Where they are proposed demonstrate no adverse impacts on the environmental values of the riparian buffer area.

Issue
Borehole 27 is required to be remediated in riparian buffer area in a radius of 5m.
Information Required
Demonstrate how the values of the riparian buffer area will be maintained and enhanced through the remediation process.
Issue
Appendix B of the Callahan and Toth Stormwater Management Plan shows the site soils contains traces of chemicals with previous uses of the site.
Information Required
Provide information from a suitably qualified health professional about the suitability of the site for a playground with respect to the proposed usage of the site as a children’s playground and the historic use of the land. Consideration of site excavations, soil loading and long term usage by children and other vulnerable users should be presented. In this regard, the qualified health professional’s response should make reference to the two reports prepared by Core Consultant’s (March and December 2019).
Provide copies of the two reports prepared by Core Consultant’s (March and December 2019) referenced in the Stormwater Management Plan.
Issue
Appendix B of the Callahan and Toth Stormwater Management Plan shows the site soils contains traces of chemicals associated with previous uses of the site. No information is provided for the portion of the playground in the road reserve of Maple Street.
Information Required
Provide information regarding the likelihood of the Maple Street road reserve containing traces of chemicals associated with previous uses of the site.

due date for response to information request
The due date for providing the requested information is 11 June 2020. Please advise Council of your response to this information request in accordance with section 13 of the Development Assessment Rules.
If you do not provide a response before the due date, it will be taken as if you have decided not to respond to the information request and Council will continue with the assessment of your application.
