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.
