Appendix D - Civil Engineering Report

2 Stormwater Drainage

The strategy and constraints associated with stormwater drainage were assessed as part of a separate
investigation by Calibre Consulting and are not covered in detail within this report.

A summary of the stormwater drainage elements is provided in the following sections of this report.


2.1    Existing Drainage System

Stormwater runoff from the subject site currently discharge via overland sheet flow over the northern property
boundary.

No existing Council stormwater network has been identified downstream of the subject site as part of this
investigation.


2.2    Proposed Drainage Works

It is intended to direct the stormwater discharge from the subject site to detention and treatment infrastructure,
to attenuate and treat the site’s stormwater runoff during the post-development scenario prior to discharge to
the Lawful Point of Discharge.

For additional details on the prevailing stormwater drainage conditions, strategy and constraints please refer
to the Site Based Stormwater Management Plan for the subject site prepared by Calibre Consulting.

An engineering services layout detailing the proposed services for the site is included in Appendix C.
