Auckland Council has today advised that works will be commencing mid-April on further planned remediation/asbestos containment alongside the seawall south of the Omaha boat ramp.
Tons of asbestos was previously removed along this seawall but remnants of the asbestos, which was folded into the seawall vicinity, are working their way to the surface. Hydro-seeding late last year did not achieve the protective grass coverage needed to lock down the asbestos-containing materials.
Contractors will soon be on-site to lay established Kikuyu turf over the areas which currently have the least coverage. This will be laid over a protective underlay, designed to stop materials from reaching the surface, reduce dust generation and inhibit ground disturbance. Once the turf is laid, significant watering will be undertaken for a period of 10 to 12 days to maximise the chance of it taking hold. By laying established turf, the current impact of the rabbits digging in the softer exposed materials should also be reduced. The area will remain fenced until we are confident in the success of the application.
Physical works will be carried out by UMS (Ian Miller Ian.Miller@umsnz.co.nz) and subcontractor, Turf and Drainage.
