2 Emerald IR Response

                                                               -3-

RESPONSE:
The Ground Level plan arrangement has been changed on the amended proposal plans to accommodate the
increased road dedication width at the Wimmers Lane frontage. A total of 24 vehicle spaces are provided onsite
including a dedicated loading bay. The proposed carpark widths have been maintained at 2.6m typical minimum
width excepting the PWD space which is compliant with AS 2890.6.


ISSUE – LANEWAY DEDICATION
PO17 of the Cooroy Local Plan Code states that where access to a development is taken from a laneway then a 2 metre wide
resumption from the laneway frontage is required.

INFORMATION REQUESTED
4. Provide amended plans detailing the 2 metre wide resumption along Wimmers Lane.


RESPONSE:
The resumption along Wimmers Lane has been increased from 1.5 to 2m on the amended proposal plans as
requested.


ISSUE - STORMWATER
The proposed development considers a significant increase in hardstand areas (i.e. impervious). Given the natural contours of
the site, this increased stormwater volume will be directed to the existing on-street carpark along Emerald Street to the North.
The submitted material does not include an indication of how stormwater runoff from the proposed development will be
collected and controlled.

INFORMATION REQUESTED
5. Considering that no new development can create a worsening of stormwater conditions to neighbouring properties, provide
a preliminary stormwater management plan for the proposed development. The stormwater management plan must be
prepared by a suitably qualified person (RPEQ – Registered Professional Engineer of Queensland) and include, but not be
limited to:
5.1. the design levels for the various structures;
5.2. the discharge rates at the kerb and channel outlets. Please note that the maximum discharge at any one location is
25l/sec;
5.3. clarification on the pipe type within the road reserve. Please note that the pipe type must be suitable for use in the road
reserve;
5.4. Demonstrate that the proposed stormwater system will be able to convey the stormwater generated by the new
development on a 20% AEP event;
5.5. RPEQ certification that the design is in accordance with The Noosa Plan and QUDM.
Please note that the stormwater drainage system must be a gravity system and pumps are not acceptable.


RESPONSE:
Please find accompanying Integrated Water Management Plan Document Reference No: 2213 SWQMP_Rev1
prepared by Callaghan & Toth Engineers addressing this item. Each of the subpoints are detailed in section 1.1 of
this RPEQ response.


ISSUE – RAMP
During a site inspection, Council identified a pram ramp along the south side of Wimmers Lane. The submitted documentation
does not include a pram ramp along the north side of Wimmers Lane.

INFORMATION REQUESTED
6. Provide an amended layout plan which includes a pram ramp along the north side of Wimmers Lane. The pram ramp must
provide access to the pedestrian and cycle pathway. The amended layout plan must be prepared by a suitably qualified
person (RPEQ – Registered Professional Engineer of Queensland).


RESPONSE:
The requested pram ramp at the north side of Wimmers Lane has been shown on the amended proposal plans
including those prepared by the RPEQ.


ISSUE
During a site inspection, Council identified an existing drainage outlet discharging stormwater from neighbouring roofs into the
south-eastern corner of the subject site. Council are concerned that the discharged stormwater may create pooling and slip
hazards along the proposed pedestrian cycle pathway if left unaddressed.
