The city has carried out a rock slope assessment in the wake of a series of slides and rockfalls in recent years on its mountain accesses.
The report finds that the 300 thousand dollars that is spent each year on rock scaling should remain “sufficient” but Brian Hughes, Hamilton’s technical operations manager, says it also identifies seven crossings as “maintenance priorities” due to highest risk.
Hughes adds that the visual inspection involved consultants who in some cases were rappelling on the rock face. They examined a total of 17 accesses.
Risk factors include instability, consequences of falling rock and traffic volumes.
Tagged for “maintenance priority” are the Sherman and Jolley Cut, Queen Street Hill, Wilson Street, New Mountain Road and Dewitt Road.
The Sherman Cut has also been outfitted with “steel mesh” to “control the way the rock comes down”.
