Re: RECONFIGURATION OF LOT APPLICATION (1 INTO 2)
108 GOODWIN STREET, TEWANTIN
Dear Sir/Madam,
Contour Consulting Engineers (Contour) have been commissioned to prepare a concept civil
engineering plan in support of a Reconfiguration of Lot (RAL) application for a proposed 1 into 2
subdivision, at 108 Goodwin Street, Tewantin.
We understand that once the RAL approval has been issued that our Client will be lodging a separate
Operation Works (OPW) application for Council’s assessment.
Given there is no higher order approval in place prior to the completion of our Concept Civil design, we
have provided details of our proposed approach to the following key engineering matters:
• Driveways and Crossovers; and
• Stormwater Lawful Point of Discharge.
Engineering commentary on the above aspects of the civil design is provided below.
1 DRIVEWAYS AND CROSSOVERS
The existing driveway crossover will be retained to service proposed Lot 1.
A new crossover will be constructed to service proposed Lot 2. The location of the driveway will be
determined during detailed design. Street tree’s are to be retained along Goodwin Street, where
possible.
Refer Contour’s Concept design (2756-C01) for details regarding the location of the existing driveway,
attached within Appendix A.

2 LAWFUL POINT OF DISCHARGE The subject site grades in a west to east direction towards Goodwin Street, with approximately 2.0m of fall across both allotments. We note that the existing dwelling will be demolished and minor earthworks will occur to accommodate two new flat building pads with minimal retaining walls. The site will continue to convey external flows as per pre-developed conditions. Roof water will be discharged via new kerb adapters to Goodwin Street, flowing to existing council stormwater infrastructure downstream within Goodwin Street. We consider the above provides a lawful point of discharge for the development and will enable non- worsening of peak discharges from the development to adjacent properties. Refer Contour’s Concept design (2756-C01) for concept earthworks, retaining wall locations and roofwater kerb adapters, attached within Appendix A. 3 SUMMARY Based on our investigative works, we consider that Council has no impediment to the approval of this development within the context of the driveway, crossover and/or stormwater. We therefore recommend that Council approves the application subject to reasonable, relevant, equitable and justifiable conditions. Yours Faithfully, Matt Folker – Civil Engineer For and on behalf of: CONTOUR CONSULTING ENGINEERS PTY LTD http://www.contource.com.au/ CIV2756-SW01 – 108 Goodwin Street, Tewantin 2 MF/SC
