Dear Sir/Madam

Information Request
Sustainable Planning Act 2009

I refer to your application and advise that Council requires further information to satisfactorily assess the proposal.
application details
Application No:	OPW15/0142
Proposal:	Development Permit for Operational Work - Stormwater, Drainage Works, Earthworks, Driveway, Car Parking & Landscaping
Street Address:	20 Topaz St COOROY  QLD  4563
Real Property Description:	Lot 102 SP 236318
information required
The information requested is set out below:

Civil Engineering Works

Issue
Linemarking for the internal parking areas and the on-street parking spaces.

Information Required
Amend submitted plans or provide additional plans to include:
The relevant measurements and linemarking for the parking areas and car parking spaces in compliance with AS 2890.1:2004 and AS 2890.6:2009.
Emergency vehicle space and associated manoeuvring area in compliance with the applicable current standards.
Linemarking for any changes to existing on-street parking including the proposed new two parking spaces and the additional parking spaces generated due the amendment to the access arrangement and the proposed reinstated kerb line.
Any required amendment to or removal of existing signs due to the access changes.

Issue
Additional information regarding the external stormwater drainage works is required.

Information Required
Provide a longitudinal section for the external stormwater drainage works near the proposed new access point and the northwest corner of the site including the design surface levels and invert levels.

Landscaping
Issue
Information Required
Condition 14 b) of the Material Change of Use approval (MCU13/0030.01) requires the provision of 1 street tree within the Topaz Street road reserve for every 8 metres of road frontage.

Information Required
Amend the relevant landscaping plans to include street trees and landscaping within the road reserve in compliance with the MCU permit approval. The trees shall have a minimum pot size of 45L, be consistent with other species within the street, located between the footpath and the curb, with consideration given so as to avoid interference with the door openings of cars parked within the road reserve.

Hydraulics and Water Quality
Issue
Condition 27 of MCU13/0030 requires that the stormwater treatment system is consistent with the latest version of the Water Sensitive Urban Design Technical Design Guidelines for South East Queensland. The latest version is Water by Design Bioretention Technical Design Guidelines Version 1.1 October 2014. These guidelines outline that the minimum depth of filter media should be 400mm. This is to facilitate healthy plant growth. The provided detail design drawings only propose 300mm depth of filter media.

Information Required
Update detail design plans including pipe invert levels to provide for a  minimum 400mm depth of filter media

Issue
Surface levels of the proposed swale shown on plan view Drawing 1303- 21 dated 07/15 are 105.010, which is lower than the proposed filter media surface level of the proposed biobasins which are 105.75.

Information Required
Provide plans that show finished surface levels that demonstrate that all areas of the catchment drain to the proposed water quality treatment structures pursuant to documents approved in MCU13/0030.

Issue
Details regarding separation distances between slotted underdrainage pipes, grade of fall required along pipes, requirement for un-slotted cleanout risers and details of how the underdrainage system swale will connect from the swale to the underdrainage system within the bioretention basin is absent from drawings.

Information Required
Update bioretention swale and bioretention basin underdrainage details on 1303-21 to demonstrate that there is adequate fall within the depth allocated for the drainage layer, the underdrainage system of the swale will function without causing ponding, and consistency with  Section 3.5.1.4 of Water by Design Bioretention Technical Design Guidelines Version 1.1 October 2014. Also include design details to demonstrate how the underdrainage of the swale will connect to the bioretention basin under drainage system.

Issue
Width of proposed overflow weir on drawing 1303-21.

Information Required
Demonstrate how the width of the proposed overflow weir shown on Drawing 1303-21 is consistent with Condition 27(b)(ii) of MCU13/0030 and Section 3.5.4 of Water by Design Bioretention Technical Design Guidelines Version 1.1 October 2014.

Issue
Condition 31 of MCU13/0030 provides design requirements for rainwater tanks within the development.  It is acknowledged that tanks are shown on the drawings, however no details are provided regarding their dimensions to confirm that adequate area and elevations are allocated for the required rainwater tanks.

Information Required
Provide design information for rainwater tanks on the plans to demonstrate that Condition 31 of MU13/0030 is achievable onsite.

Issue
Landscape drawings LP03-124 RvB and LP01-124RVb show similar hatching for two different landscape treatments. One of the hatching proposes for installation of 300mm topsoil and irrigation for resident gardening. This hatching is easily mixed up with the landscaping treatment required within the bioretention basin and swale.

Information Required
Update details on landscaping design plans to ensure landscaping treatments within bioretention basins are clear and consistent with Water by Design Bioretention Technical Design Guidelines Version 1.1 October 2014.

General
Issue
Payment of performance bond.

Information Required
Evidence of payment of performance bond ($10,000) is required in compliance with Condition 5 of the higher order approval (MCU13/0030.01) prior to the issue of a Development Permit for Operational Works.

Issue
Compliance with Portable Long Service Leave levy – Qleave.

Information Required
Conformation of compliance with Building and Construction Industry (Potable Long Service Leave) Act 1991 and the recent amendments to the Act.
