Blackbutt Creek Flood Study Community Bulletin - Ku-ring-gai Council

Blackbutt Creek Flood Study Community Bulletin
18 June 2013
This Community Bulletin has been issued to inform the residents of Ku-ring-gai of the
Flood Study being prepared for the Blackbutt Creek Catchment. It is the first of a series of
Bulletins planned to inform residents. Ku-ring-gai Council has engaged consultants SKM
to undertake the Flood Study.
The purpose of the study is to develop an understanding of existing flooding behaviour in
the catchment. This will enable potential flooding trouble spots to be identified for future
assessment of management strategies to reduce the impact of flooding on the
community, and assist in managing future development of the area.
An integral part of the study process is community consultation and involvement. This
element of the process aims to inform the community of the study and invite residents to
provide information on their views and experiences with flooding in the area. The
management of flood prone land is primarily the responsibility of Councils and follows a
number of stages.

The Study Area
The Blackbutt Creek Catchment includes
parts of Pymble, Gordon and Killara, and
is bounded by the Pacific Highway to the
east, Avon Road to the north, Ryde Road
to the west and Fiddens Wharf Road to
the south. The creek joins the Lane Cove
River just downstream of Ryde Road
bridge.
The flood study will investigate flooding in
the main creeks, minor watercourses and
in overland flow paths.

The Flood Problem
Steep terrain and ridge-top development
has led to major flood risk in Ku-ring-gai,
arising from flash flooding along
headwater streams and drainage

flooding occurs means that there is
usually no time for damage reduction
measures to be put in place, or for
evacuation to be undertaken as required.
The Blackbutt Creek Catchment is one of
Ku-ring-gai’s most significantly flood
affected areas.
Objectives of the Study
1) Understand the current flooding
interested to receive records of
flooding in your area including
photographs, observations of flood depths or some comments on your experience. You
can help us with this information by completing the questionnaire which will be
distributed in the mail.
How can you get involved?
Engagement of the community in the floodplain risk management process is very
important to Council. We will be providing a number of opportunities for the community
to have input to the floodplain risk management plan. These are outlined below.

2) Construct a computer flood model
which can be used to simulate the
size and extent of potential future
floods.
3) Identify potential problem areas for
further investigation.
