e It has apparently been acknowledged by Council that the group of Melaleucas identified
in the second dot point will be disturbed by the required kerb and channel works;

e We believe that only one of the two Bloodwood trees identified in the third dot point —
that in front of Lot 11 — will need to be removed;

e The two Blackbutt trees identified in the fourth dot point should be able to be retained;

e Unfortunately, one other large tree — a Blackbutt in front of Lot 5 — will need to be
removed, due to its unavoidable disturbance by the required kerb and channel works.

2. Provide an assessment of the likely works on the health and structural integrity of trees
within the road reserve.

(a) This assessment is to include a situational report on the current health of the trees to
be retained and estimate useful life expectancy in their current state.

(b) The assessment must include recommendations for works within the tree tunnel
boring to protect root zones.

(c) The assessment must coordinate the requirements of the other disciplines and may
include the re-positioning of driveways, non0O-standard alignment of services and
other methods to reduce and/or eliminate works within the tree protection zones.

Response:
The trees proposed to be removed due to their conflict with construction works have been

identified above. It is anticipated that all of the other tress within the road reserve — those
intended to be retained - will be assessed by an arborist once detailed operational works plans
have been completed, following approval of the application (REC15/0011) for reconfiguration.

3 Please remove from the plans the 3m wide gravel access along the western perimeter of
proposed lots 9 & 11, and the specific access driveway within the road reserve for direct
access to the bioretention basin.

Response:
This has been attended to — refer to the enclosed, amended proposal plans prepared by TOD

and RPS.
Frontage Works

There are concerns the construction of the proposed open drain and access pipes (300mm)
along the front boundaries would likely cause damage to the roots of the existing trees with the
road reserve warranting retention.

Information Required

4. Amend the plans to include a kerb edge for the full length of the frontages of the site as
follows:

(a) Provide kerb and layback for the driveways by replacing the existing flush kerb or
constructing it along and adjoining the existing kerb.

(b) Provide grassed verge between the internal top of kerb and the edge of the existing
concrete footpath generally at 1:4 batter.

(c) Provide stormwater collection pits at both ends of the kerb line and direct flows to
the proposed bio-retention basin or treatment train.

Response:
The above items are reflected in schematic terms on the enclosed, amended Layout Plan, Sheet

15513-SK01 Revision E prepared by TOD.

Services Alignment

There are concerns regarding the alignment and depth of the trenches for the proposed sewer
main and their impact on existing trees.

It is acknowledged the assessment and approval for the design and the construction of the sewer
main is the responsibility of Unitywater. However, given the depth of the proposed sewer main,
Council seeks to ensure the impact on existing mature trees is prevented or minimised.

Information Required

5. Provide a preliminary design for the proposed sewer main that include:

(a) Alignment and depth of the sewer main.

(b) Existing trees that may be affected by the works and measures to protect them.

(c) The sections of the line that will be tunnel-bored to protect existing trees and

services.

Response:
Refer to the enclosed, amended Layout Plan, Sheet 15513-SKO1 Revision E prepared by TOD;
the alignment has been chosen to have minimal impact on existing trees, as is evidenced by the
preliminary layout depicted on Sheet 3 of the plan. The depth of the sewer can be established
from the designed lid and invert levels shown on the plan. Also, there appear to be no significant
trees likely to be impacted by the proposed route of the sewer after it leaves the site and heads
east along George Street, before crossing the road (by tunnel bore) between two large trees
(which are yet to be precisely located) to an existing manhole. There would seem to be sufficient
grade and space along George Street to ensure that the indicative layout depicted will very
closely approximate the final design, subject to detailed survey to be undertaken as part of the
operational works design and approval process.

6. Provide details on how methods will be engaged to ensure third party service providers
and inexperienced operators do not impact on trees designated for retention.

Response:

It is anticipated that a report addressing this matter will be prepared once a detailed survey has
been undertaken and operational works plans have been completed, following approval of the
application (REC15/0011) for reconfiguration.
