Waterfall Road work will cost $500,000
By Local Government correspondent Jeremy Smith
Re-opening Paraparaumu’s Waterfall road, closed by slips since September, will cost about half a million dollars.
But more than half of this, $287,000, will be subsidised by the New Zealand Transport Authority (NZTA), leaving the Kapiti Council to pick up the remaining $213,000. A part of this amount has been contracted to Hero Services, to take care of electrical works that would come up.
Work will drain KCDC special budget
KCDC will fund $50,000 of this from its Emergency Works budget, which will completely drain the budget. The remainder will come from contingency funds.
Councillors have been warned that they might have approve even more spending if the district is hit by storms like the ones which brought down slips on Waterfall Road in 2013 and 2014.
NZTA’s contribution to the work is because Waterfall Road is the only detour route if Highway One is closed between Raumati and Mackays Crossing.
The September closure came after an inspection showed cracks at the top of the slip site, which dates back to 2014, had widened and the slope was slumping.
Engineers estimate that 3000 to 5000 cubic metres of soil could come down on the road.
Some 2500 truckloads ahead
Clearing the area will require approximately 2,500 truck loads. The work could take two to three months. The material will go Otaihanga landfill but some may go to a company site at Poplar Avenue.
And work can’t start until Electra has moved two power poles which supply electricity to Paekakariki. The poles are close to the top of the slip above Waterfall Road.
KCDC’s Sean Mallon, Group Manager Infrastructure Services, says a start date also depends on receiving further engineering information.
