Sediment loss under spotlight

Smaller building sites are coming under the spotlight from compliance teams as Auckland Council tightens up on sediment loss.

Two years ago, Council started cracking down on sediment control in an effort to reduce the amount of uncontrolled sediment being washed into the waterways and surrounding harbours.

Regulatory Committee chair Councillor Linda Cooper says the Closing the Gap initiative has been largely successful and seen non-compliance on larger sites drop from 40 per cent to 20 per cent, over 18 months.

But smaller sites have largely flown under the radar until now.

While much of the sediment entering waterways and harbours in the north has historically come from farm runoff and forestry, with more building in the area sediment looks set to become more of a problem, even with high compliance rates.

New housing density rules come into play on August 20 and are likely to see more smaller building sites cropping up around the area. With no building consents needed to meet new Medium Density Residential Standards, compliance officers keeping a closer eye on builds for sediment control will be more important.
