Retaining Walls around Kotara
Development on a Kotara slope is stepped to the same cut and fill limits as anywhere else in Newcastle: a maximum of 3 m of cut and 1 m of fill inside the building envelope. The suburb's own retaining walls are named in the plan as a feature of the area.
A site with a slope of 35 degrees or more, a known history of landslides, or a major cut or fill variation needs a site-specific geotechnical report. The concrete sleeper page below sets out the cut, fill, boundary and drainage lines in full.
Permits and City of Newcastle rules
A wall that is not exempt or complying development needs a development application to City of Newcastle. Exempt means no more than 600 mm high and clear of boundaries, easements, sewer and water mains, so check the lines on the main retaining walls page and confirm with Council before work starts.
