            Information Required
            2. Provide an amended Roadworks and Stormwater Drainage Plan that includes the
                 ongoing/future works downstream (i.e., the removal and relocation of the existing
                 stormwater pit fronting 22 Grant Street). The amended plans must be prepared by a
                 suitably qualified person (RPEQ).

RESPONSE
Please refer to the Engineering Responses and updated Engineering Plans in Attachments 3 and 4. Barlow
Shelley has contacted the adjacent property developer and builder to coordinate the outcome. It is proposed
that the adjacent property builder remove the existing pit and cap the line. Our client’s proposed development
would then extend the stormwater pipe from the top of the existing line to the site frontage to provide
connection. The adjacent site owners are amenable to this as it avoids trenching through their newly constructed
driveway. The proposed solution is documented on the revised Engineering Drawings in Attachment 4.



            ITEMS 3 & 4:
            Issue – Earthworks Levels
            The interface between the proposed finish levels within the subject site and the existing
            natural ground levels of the adjacent properties is unclear. Council is unable to accurately
            assess the impacts of the proposed earthworks on adjoining properties.

            Information Required
            3. Provide site-specific survey data detailing the existing levels along the north-western
                 and south-eastern shared property boundaries. The site-specific survey data must be
                 prepared by a suitably qualified person.
            4. Provide amended Bulk Earthworks Plan (C101) and Earthworks Sections (C102) that
                 highlights the levels at the interface between the subject site and the neighbouring
                 properties. The amended plans must be prepared by a suitably qualified person (RPEQ),
                 incorporate data for site-specific survey, and include, but not be limited to:
                 a. Spot levels of the proposed finished levels along the north-western and south-
                       eastern shared property boundaries; and
                 b. Natural ground line in all earthworks sections.

RESPONSE
Please refer to the Engineering Responses and updated Engineering Plans in Attachments 3 and 4. There is
active construction occurring on the south-eastern property boundary shared with No. 22 Grant Street. The
levels and cross sections shown on the updated plans in relation to this boundary refer to the current
construction drawings for the adjacent site when referencing the adjacent basement construction. The
boundary shared with No. 18 Grant Street is consistent with the levels shown on the survey plan prepared by
LSD surveyors, except where adjacent to the carport. The existing retaining wall here is approximately 0.4 –
1.4m high. In this location, stairs for access are required for Unit 1 so the proposed development finished levels
are consistent with the existing site levels.

The updated Engineering Plans (Attachment 4) include levels from the survey file along each boundary and
sections with the natural ground lines (as surveyed) shown.
