Dear Sir
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.	OPW21/0219
Street Address:	12 Grosvenor Tce Noosa Heads Qld 4567
Real Property Description:	Lot 19 SP 188268
Planning Scheme:	Noosa Plan 2020 (25 September 2020)
INFORMATION REQUIRED
The information requested is set out below:
Issue
Council has concerns with the submitted plan that indicates the levels and direction of surface flows for the hardstand area within the site between the built structures and the road reserve. The plan has not been prepared by a suitably qualified person (either a registered surveyor or a registered engineer). Council has concerns that the catchment areas used during the engineers calculations are not correct and additional runoff will be directed to the road formation. It is noted that the constructed driveway does not include a grated drain adjacent to the front boundary to collect flows to the on-site infiltration system
Information Required
Provide a plan of the levels and slopes of the existing hard stand areas within the site between the built structures and the road reserve. The plan must include sufficient detail to demonstrate where runoff is directed (on-site infiltration or off site) and be prepared by a suitably qualified person (either a registered surveyor or a registered engineer).
Provide commentary from the design engineer that makes reference to the abovementioned plan and the calculated flow rates in Grosvenor Terrace and if necessary, provide amended commentary/design plans.
Issue
The submitted document prepared by AAA Design and Development make reference to the plans approved for the adjoining property (No 14 – OPW20/0247) and assumes that the direction of flows from the “swale” to the road edge are intended as a permanent solution. This is not correct. The redirection of flows to the road edge are intended as a temporary solution until the issues with the constructed access to No 12 are resolved. Council has concerns that the constructed driveway to No 12 will impact on the flows to such an extent that runoff from the road verge will top the highpoint in the driveway to No 14 and enter the basement garage area.
Information Required
Provide certification from a Registered Engineer of Queensland (RPEQ) that states that the constructed driveway to No 12 Grosvenor Terrace will not impede surface flows for all events up to an including the 1% AEP to such an extent that flows will top the highpoint in the driveway to No 14 Grosvenor Terrace and enter the basement garage area of No 14 Grosvenor Terrace.
Issue
Council has some concerns with the construction of the proposed M1 kerb and the long and short term impacts on the road formation.
Information Required
Provide a construction management plan prepared by a Registered Engineer of Queensland (RPEQ). The plan must include but not be limited to:
the methodology for the removal of the existing flush kerb and the construction of the new kerb
any site specific measures/methods to ensure that water will not impact on the road formation
a traffic management plan
due date for response to information request
The due date for providing the requested information is 17 December 2021. Email your response to [email protected]. 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.
