Greater Wellington works with communities to manage flood risk from the region's rivers and streams. We develop floodplain management plans, provide a free advice and consultation service in relation to flood and erosion risks, maintain and build flood protection works, work with the community to maintain or improve the environment and recreational opportunities and provide management and advice to Civil Defence during large floods.
Greater Wellington Regional Council manages and maintains flood protection assets along 800km of river across the region. These assets are valued at $263million, and include 290km of stopbanks and 554,000 tonnes of rock. We also manage 155km of drainage channels which support farming or allow established land-uses to continue, and the single most expensive asset owned is the Lake Wairarapa Barrage gate, which is valued at $18million, its purpose is to manage the water levels within lake Wairarapa.
Maintenance of these assets is carried out all year round by our own skilled Operation and Maintenance teams based in the Hutt Valley, Wairarapa Valley and on the Kapiti Coast.
