Dear Shane
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.	OPW18/0293 (Related Files: 132007.12.8, OPW18/0118, REC13/0109.01)
Street Address:	88a Goodchap St Noosaville Qld 4566
Real Property Description:	Part Lot 3 SP 264909 (and external site for Temporary Parking: Lot 1 RP230931)
Planning Scheme:	The Noosa Plan (8 June 2018)
INFORMATION REQUIRED
The information requested is set out below:
External Sites
Issue
The application proposes use of an external site which has not been not included in the application Form 1. Also, the current vehicle access to this external site is shared with another property and no consent from the adjoining owner (No 99 Eumundi Noosa Road) has been provided.
Information Required
The following information is required:
Submit an amended Form 1 that includes the external site for the “temporary” carpark use.
Provide written consent from the adjoining property owner (No 99 Eumundi Noosa Road) to utilise the existing access for the temporary carparking use.

Existing Stormwater Works
Issue
The submitted design has not addressed the existence of a large stormwater inlet pit and a connecting stormwater pipeline/s near the northwest corner of the site that receives stormwater runoffs from the Telstra site.
Information Required
Provide updated plans and details for the modification for the existing pit and pipeline supported by assessment of stormwater runoff quantities received from Telstra site and how this impact on the stormwater management on the development site and the proposed biobasin design. Also, to note an inter-allotment drainage easement will be required over any stormwater drainage works receiving stormwater flows from external property, such easement needs be indicated on the updated plans.
Pathway
Issue
It is noted that an existing pit north of the end of the proposed pathway upgrading works is poorly constructed or damaged and posing trip hazard.
Information Required
Update plans to include repair/upgrade of the above mentioned pit or extend the proposed pathway works further north to include the pathway adjoining this pit.
Stormwater Quality
Issue
Specific outcome O1 of Water Sensitive Design Code requires that downstream properties are not adversely impacted by the development.
Drawing 15652-SK1 shows the Bioretention basin will extend right up to the property boundary with the invert level from the outlet pipe at RL4.7, meaning that the outlet will daylight beyond the property boundary.
The response provided by the applicant to this same issue in application MCU 132007.12.8 stated that the outflow would be to an existing scour protection pad that is located within the rehabilitation area.
Information Required
Provide detailed information including survey levels to demonstrate how the 450mm RCP stormwater outlet will tie into the receiving scour protection area in a way that will not pond water or require works off the property, that the existing scour protection pad is a sufficient for the amount of flow expected, and the rights that exist for the scour protection to serve the subject property, to remain on the property it is currently located on.
Issue
The application includes excavations below the elevation of 5m AHD and as such triggers assessment against the Acid Sulftae Soil overlay code.
Information Required
Demonstrate how the application meets the Performance Outcomes of the Acid Sulfate Soils Overlay Code.

Issue
Although the Stormwater Management Plan by AquaIntel provided with and approved via 132007.12.8 includes the Telstra Site within the stormwater quantity treatment assessment, it does not include the Telstra site within the stormwater quality treatment component. The detail design plan shows for all runoff to be directed to the bioretention basin, which means that the bioretention basin will be treating the quality of runoff from the Telstra site, and is inconsistent with the MUSIC model provided in the Aquaintel report.
Information Required
Demonstrate how the development will be treating the quality of stormwater in accordance with the AquaIntel report provided with and approved via 132007.12.8 to achieve the required pollution reduction targets, and not causing the bio retention basin to be over loaded with nutrients from the Telstra site.
Issue
The batters to the bioretention basin are proposed to be 1:1. These are extremely steep, in excess of the Planning Scheme Policy and difficult to access the basin floor for maintenance. In addition, the information request response for 132007.12.8 proposed for maintenance access to be provided at the eastern end of the basin, however this has not been demonstrated within the application.
Information Required
Demonstrate why there is no alternative to the 1:1 batters for the bioretention basin and demonstrate how ongoing maintenance access to the biobasin will be achieved (Note: a consideration could be given to have a retaining wall for one side of the biobasin along the edge of parking area – with any necessary fall protection, if this can assist the overall design outcome).
Issue
Overland sheet flow to bioretention basins can lead to scour of the batters.
Information Required
Demonstrate how construction will be managed to prevent scour of the batters via overland flow to the bioretention basin.
Issue
There is no detail design provided for the overflow weir of the Biobasin.
Information Required
Provide detail design of the overflow weir from the biobasin.

due date for response to information request
The due date for providing the requested information is 3 months from the date of the request. 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.
