Planning Case Study

In the late 1990's, Wyong Shire Council engaged Shirley Consulting Engineers [in conjunction with the University of NSW] to identify the potential for instability in the various cliff and headland areas within the Council area north of The Entrance. The study required the firm to provide specific recommendations / guidelines as to methods of dealing with the various hazards, and coastline hazard zoning maps for use by the Council's officers in development control & planning.

This major hazard zoning study resulted in:

• Detailed maps of the Wyong Council coastal area north of The Entrance at a scale of 1:4,000 which identified areas of potential landslip / rockfall / bluff instability; and
• Policy recommendations for the proposed coastal development control plan.

In 2004, and after unsuccessful attempts had been made by others to extend the original work by Shirley Consulting Engineers, the firm was re-engaged by the Wyong Shire Council to undertake a comprehensive investigation of the entire Wyong Shire coastline and to provide detailed hazard management options. The scope of the 2004 Coastline Management Study included both an update & expansion of the original work, as well as an extension of the study area to include the headland / bluff areas south of The Entrance, to the southern extremity of the Shire at Yumbool Point.
