A walkover of the Quarry Gardens will start at 4:30pm to view some of the slips caused by Cyclone Gabrielle, and subsequent remedial works undertaken by WDC and the Quarry Gardens.
The Garden Manger Thomas Nance will talk through the effect the Weather Event had on gardens operations. Due to the slips the main access track into the gardens was blocked for several months, with the upper area of the gardens unsafe to access due to the access track passing below the slip scarp. Slip material has been moved offsite in the year since the cyclone and there has been an attempt to contain sediment before it enters the stream.
A slip inundated the stream and destroyed the old footbridge providing access to the gardens, this bridge has since been replaced. To facilitate access to the otherwise closed-off lake area, a new concrete foot bridge has been installed across the lake spillway.
Trevor Barfoote will discuss the two new pedestrian bridges at the gardens, including how a bridge from Moerewa has been recycled.
Geotechnical Director of Hawthorn Geddes, Callum Sands, will talk through the assessment of geotechnical risk undertaken and ongoing for the continual use of the gardens.
Challenges at this site include funding these works, ongoing wet weather, ongoing slip movement and safety.
